38 C’est le même phénomène qui fait monter le parfum dans mon vaporisateur _____________________________________________________________________ The same effect makes the perfume come out of my spray. _____________________________________________________________________
_____________________________________________________________________ …and it sucks smoke up chimneys – with help from the wind. _____________________________________________________________________ ... и поради това пушекът се всмуква в камината. _____________________________________________________________________ Depuis quand les cheminées parlent-elles ? _____________________________________________________________________ I never knew chimbleys spoke before! _____________________________________________________________________ Откога камините могат да говорят? _____________________________________________________________________ Bizarre, j’aurais plutôt cru que l’air se serait entassé dans cet entonnoir. _____________________________________________________________________ Nuts. I’d always fought that the air got trapped in this bloomin’ funnel! _____________________________________________________________________ Странно, по-скоро бих си помислил, че въздухът се е насъбрал в тази фуния. _____________________________________________________________________ Enoncé suivant la LOI DE BERNOULLI : Pression et vitesse varient inversement. La Direction _____________________________________________________________________ Here is an announcement:
Pressure and speed vary inversely The Boss _____________________________________________________________________ Обявяваме, че според ЗАКОНА НА БЕРНУЛИ: Колкото е по-голяма скоростта на въздушния поток, толкова е по-малко налягането в него и обратно. Ръководството ____________________________________________________________________ A la vérité, la mécanique des fluides défie bien souvent notre intuition et notre sens commun. _____________________________________________________________________ It’s true – fluid mechanics really does defy intuition and common sense. _____________________________________________________________________ Всъщност, механиката на флуидите често не се подчинява на нашата интуиция и здрав разум. _____________________________________________________________________ 39 Exemple de PARADOXE lié à la loi de Bernoulli : _____________________________________________________________________ Example of a
_____________________________________________________________________ Пример за ПАРАДОКС, свързан със Закона на Бернули: _____________________________________________________________________ C’est pas intuitif pour un rond. Enfin… _____________________________________________________________________ It sure ain’t h’intuitive an’ that’s a fact! Now - _____________________________________________________________________ Интуицията е неприложима към опита с диска и тръбата. Тогава... _____________________________________________________________________ Qu’est-ce que c’est que cela ? Encore un de leurs trucs ! _____________________________________________________________________ ‘ere, wot’s this ‘ere there then? Anuvver one of their bleedin’ toys? _____________________________________________________________________
_____________________________________________________________________ ASPIRISOUFFLE _____________________________________________________________________ BLOWSUCKER _____________________________________________________________________ ДУХАТЕЛНА ТРЪБА _____________________________________________________________________ Apparemment c’est un simple tube collé sur un disque _____________________________________________________________________ It jus’ looks like a cardboard choob stuck to a disc… _____________________________________________________________________ Прилича на най-обикновена тръба, прикрепена към диск. _____________________________________________________________________ Tube qu’il pose sur une boite d’allumettes !!! _____________________________________________________________________ _____________________________________________________________________ Now, why’s ‘e stickin’ the choob on to that box of matches? _____________________________________________________________________
_____________________________________________________________________ 40 Il…souffle…et il soulève la boite !!! _____________________________________________________________________ Wotthe’eck? ‘e – ‘e’s blowin’ an’ it’s liftin’ the box!! _____________________________________________________________________
_____________________________________________________________________ Misère… _____________________________________________________________________ Cripes _____________________________________________________________________ Олеле! _____________________________________________________________________ Comment peut-on aspirer en soufflant ? _____________________________________________________________________ ‘ow can yer suck by blowin’? _____________________________________________________________________ Как можеш да вдишваш въздух, докато го издишаш? _____________________________________________________________________ Au raccord cylindre - disque, la section de passage du gaz diminue brusquement et l’air est violemment accéléré. La pression devient alors inférieure à la pression atmosphérique. _____________________________________________________________________ At the junction of the cylinder and the disc, the width for the gas to pass through drops suddenly, and the air speeds up violently. The pressure drops below that of the atmosphere. _____________________________________________________________________ На мястото, където цилиндърът и дискът се свързват, широчината на прохода за газа изведнъж се свива и скоростта на въздуха рязко се покачва. Налягането става по-ниско от атмосферното. _____________________________________________________________________ La partie périphérique est, par rapport à la pression atmosphérique, en dépresson _____________________________________________________________________ …the outside part is at a lower pressure than the atmosphere. _____________________________________________________________________ Налягането в периферната част е по-ниско от атмосферното. _____________________________________________________________________ La portion de la paroi de la boite qui est en face de canal central, se trouve, vis-à-vis de la pression ambiante, en surpression _____________________________________________________________________ The part of the box opposite the hole in the tube is at a higher pressure than its surroundings… _____________________________________________________________________ Тази част от стената на кутията, която е разположена срещу централния канал, се намира в състояние на повишено налягане по отношение на околния въздух. _____________________________________________________________________ 41 Il se trouve que le résultat de tout cela est une succion _____________________________________________________________________ It turns out that the result of all that is suction… _____________________________________________________________________
_____________________________________________________________________ Vous pouvez réaliser une expérience analogue avec une simple feuille de papier : _____________________________________________________________________ You can produce a similar effect using only a sheet of paper. _____________________________________________________________________ Можете да осъществите подобен опит с най-обикновен лист хартия: _____________________________________________________________________ Tenez-la comme ceci _____________________________________________________________________ Hold it like this… _____________________________________________________________________ Дръжте го ето така. _____________________________________________________________________ Soufflez ici, très fort. _____________________________________________________________________ Blow here, very hard… _____________________________________________________________________ Духнете силно тук. _____________________________________________________________________ Dès que vous soufflez, lâchez la feuille. Elle restera un court moment plaquée. _____________________________________________________________________ As you blow, let go of the paper. It will stay in place for a few moments. _____________________________________________________________________ Докато духате, пуснете листа. Той ще остане прегънат за известно време. _____________________________________________________________________ Nota bene : Il faut souffler FORT ! La Direction _____________________________________________________________________ N.B. Blow HARD!! The Boss _____________________________________________________________________ Забележка: Трябва да се духа СИЛНО! Ръководството _____________________________________________________________________
Tu viens voler un peu ? _____________________________________________________________________ How about coming for a flight? _____________________________________________________________________
_____________________________________________________________________ Avec tout ce que j’ai vu aujourd’hui, je préfère aller à pied ! _____________________________________________________________________ After wot I seen today, mate, I’d rather walk!!! _____________________________________________________________________ След всичко, което видях днес, предпочитам да вървя пеша. _____________________________________________________________________ Fluide, densité, pression, température, réaction Bernoulli. J’ai tous les maîtres - mots pour voler. _____________________________________________________________________ Fluid, density, pressure, reaction, Bernoulli – I should have all the words I need to get off the ground. _____________________________________________________________________ Течна среда, плътност, налягане, температура, формула на Бернули.

Non, il t’en manque un _____________________________________________________________________ No, there’s one missing. _____________________________________________________________________ Не, една дума ти липсва. _____________________________________________________________________ Lequel ? _____________________________________________________________________ Which? _____________________________________________________________________ Коя? _____________________________________________________________________ 43 LE SONGE DE LANTURLU : _____________________________________________________________________ ARCHIBALD’S DREAM: _____________________________________________________________________ СЪНЯТ НА ЛАНТУРЛУ _____________________________________________________________________ Nom d’un vortex où suis-je ?? _____________________________________________________________________ Good grief! Where am I? _____________________________________________________________________ И таз добра! Къде съм? _____________________________________________________________________ Apparemment je suis dans un submersible. Quel endroit inquiétant !... _____________________________________________________________________ Apparently in some kind of submarine. That gives me a sinking feeling… _____________________________________________________________________ Май съм в подводница. Много несигурно място. _____________________________________________________________________ Il faut que je sorte d’ici au plus vite _____________________________________________________________________ I’ve got to get OUT of here fast! _____________________________________________________________________ Трябва час по-скоро да изляза оттук. _____________________________________________________________________ Cette machine a deux modes de propulsions, des rames et une hélice mue par des pédales. _____________________________________________________________________ There seem to be two ways to move this machine – Oars, and a propeller driven by pedals. _____________________________________________________________________ Тази машина може да се задвижи по два начина – с гребла и с витло, задвижвано от педали. _____________________________________________________________________ 44 Diable, je pédale depuis une heure… _____________________________________________________________________ Hell, I’ve pedaled for an hour _____________________________________________________________________
_____________________________________________________________________ …et je n’avance pas d’une pouce ! _____________________________________________________________________ …and I haven’t budged a millimeter! _____________________________________________________________________ ... и не напредвам и сантиметър! _____________________________________________________________________ Essayons les rames…ça ne donne rien non plus…et je ne sens aucune résistance !! _____________________________________________________________________ Let’s try the oars…they’re not doing anything either. There isn’t even any resistance! _____________________________________________________________________ Да опитам с греблата... Пак нищо не става... Не усещам никакво съпротивление! _____________________________________________________________________ Je dois être dans le vide ? Et non, si j’étais dans le vide, mon submersible ne flotterait pas ! _____________________________________________________________________ Am I in a vacuum? No, the submarine wouldn’t float… _____________________________________________________________________ Сигурно се намирам в пустотата. Не, ако бях в пустотата, подводницата ми нямаше да се движи. _____________________________________________________________________ 45 Tiens, on dirait que je remonte _____________________________________________________________________ Crikey, it looks like I’m surfacing! _____________________________________________________________________
_____________________________________________________________________ Par tous les tourbillons de l’enfer, Sophie, explique-moi ce que tout cela signifie ! _____________________________________________________________________ By all the wind-devils of hell, Sophie – what’s been going on? _____________________________________________________________________ В името на всички дяволи, Софи, обясни ми какво означава всичко това? _____________________________________________________________________ HELIUM SUPERFLUIDE _____________________________________________________________________ SUPERFLUID HELIUM _____________________________________________________________________ ХЕЛИЙ СУПЕРФЛУИД _____________________________________________________________________ 46 Tu étais simplement dans de l’hélium SUPERFLUIDE. Rappelle toi l’histoire de la caisse de sable. Le frottement des grains les uns sur les autres était tellement important que le sable s’écoulait avec difficulté. Ici c’est l’inverse. En dessous d’une certaine température, très basse, la fluidité de l’hélium devient infinie et les frottements nuls. _____________________________________________________________________ You were just in some SUPERFLUID helium. Remember what happened in the sandbox? The friction of the grains of sand against each other was so great that the sand only flowed with difficulty. Here it’s the opposite. Below a certain very low temperature, the fluidity of helium becomes infinite, and there is no friction at all. _____________________________________________________________________
_____________________________________________________________________ Mais quel rapport entre les frottements, et le fait de ramer, de voler, ou de se propulser à l’aide d’une hélice ? _____________________________________________________________________ But what’s friction got to do with rowing, flying, or propelling yourself with a propeller? _____________________________________________________________________ Но каква е връзката между триенето и гребането, летенето или придвижването с помощта на витло? _____________________________________________________________________ Tu avais raison, en un sens, avec ton parapluie. Pour prendre appui sur l’air, il faut avoir prise sur lui. _____________________________________________________________________ You had the idea, in a way, with your umbrella. To get support from the air you have to grab hold of it. _____________________________________________________________________ В известен смисъл имаше право, с чадъра. За да се задържиш във въздуха, трябва да се държиш за него. _____________________________________________________________________ Si l’air était SUPERFLUIDE, ton parachute ne te servirait à rien. Pire, il ne se gonflerait même pas et tu tomberais en chute libre ! _____________________________________________________________________ If the air were SUPERFLUID, your parachute wouldn’t be any use. Worse – it wouldn’t open, and you’d fall like a stone. _____________________________________________________________________ Ако въздухът бе СУПЕРФЛУИД, парашутът нямаше да ти послужи за нищо. Дори по-зле – той нямаше да се издуе и ти щеше да паднеш! _____________________________________________________________________ 47 Le premier animal qui entreprit d’escalader les cieux comprit vite qu’il lui faudrait s’accrocher, d’une manière ou d’une autre, à ce milieu. _____________________________________________________________________ The first creature who tried to reach for the sky quickly found out that one way or another, it would have to grab the air… _____________________________________________________________________
_____________________________________________________________________ So the flight of a heaver-than-air device is like an endless attempt to gain a hold on something so tenuous that it always slips from your grasp. _____________________________________________________________________ По този начин полетът на един обект, който е по-тежък от въздуха, прилича на безкраен опит да се задържиш за нещо толкова разредено, че винаги ти се изплъзва. _____________________________________________________________________ Encore faut-il pouvoir prendre appui sur ce milieu. _____________________________________________________________________ So you have to find some way to get support from such a medium. _____________________________________________________________________ Може още веднъж д опиташ да намериш опора в такава среда. _____________________________________________________________________ Si celui-ci est SUPERFLUIDE les molécules glissent les unes sur les autres et sur les objets sans aucun FROTTEMENT. Les oiseaux sont alors contraints d’aller à pied, les éoliennes ne tournent pas et les transports aériens ne peuvent être assurés que par des ballons propulsés par réaction. _____________________________________________________________________
If it’s SUPERFLUID, the molecules slip past each other, and past objects, with no FRICTION. The birds would have to go on foot, windmills wouldn’t turn, and aerial transport would have to be achieved using balloons with reaction motors. _____________________________________________________________________ Ако тя е СУПЕРФЛУИД, молекулите се плъзгат една в друга и върху обектите без никакво ТРИЕНЕ. Тогава птиците щяха да бъдат принудени да ходят пеша, вятърните мелници нямаше да се движат, а въздушният транспорт щеше да се извършва само с балони, които се движат благодарение на реактивна тяга. _____________________________________________________________________ Le vol est donc lié au frottement gazeux. _____________________________________________________________________ Flying thus depends on gaseous friction. _____________________________________________________________________ Следователно полетът е свързан с триенето на газовете. _____________________________________________________________________ Каталог: JPP -> telechargeables -> bulgare bulgare -> Joyeuse apocalypse bulgare -> Всичко е относително jean-Pierre Petit Жан-Пиер Пети bulgare -> Приключенията на анселм лантюрлю énergétiquement vôtre bulgare -> A quoi revent les robots run, robot, run bulgare -> Cosmic Story bulgare -> Знание без граници Le Trou Noir bulgare -> Les Aventures d’Anselme Lanturlu Изтегляне 0.6 Mb.
