Ngaphandle kobuchwepheshe be-liquidi-hydrogenkanye noketshezii-helium, ezinye izinsiza zesayensi ezinkulu zingaba yinqwaba yezinsimbi ezilahliwe… Ibaluleke kangakanani i-hydrogen noketshezi lwe-helium?

Ososayensi baseShayina banqoba kanjanii-hydrogenkanye ne-helium engenakwenzeka ukucwiliswa? Ngisho ukleliswe phakathi kwabahamba phambili emhlabeni? Ake siveze izihloko ezishisayo njengokuthi “I-Ice Arrow” nokuvuza kwe-helium, futhi singene esahlukweni esihle kakhulu semboni yezwe lami ndawonye.

I-Ice Rocket: Isimangaliso se-Liquid Hydrogen kanye ne-Liquid Oxygen

Thina i-Long March 5 carrier rocket yaseChina, i-"Hercules" yemboni ye-aerospace, "90% kaphethiloli iwuketshezii-hydrogenku-minus 253 degrees Celsius kanye ne-liquid oxygen at minus 183 degrees Celsius” - lokhu kuseduze nomkhawulo wezinga lokushisa eliphansi, futhi kungumsuka wegama elithi "Ice Rocket".

Kungani ukhetha i-hydrogen ewuketshezi?

Isizathu silula: isisindo esifanayo sei-hydrogeninomthamo ophindwe izikhathi ezingaba ngu-800 we-hydrogen ewuketshezi. Ngokusebenzisa uphethiloli owuketshezi, “ithangi likaphethiloli” lerokhethi longa isikhala esiningi, futhi igobolondo lingaba lincane, ukuze lithwale imithwalo eyengeziwe esibhakabhakeni. Inhlanganisela ye-hydrogen ewuketshezi kanye ne-oxygen ewuketshezi ayigcini nje ngokuhambisana nemvelo, kodwa futhi ingakhiqiza ukukhuphuka kwesivinini esikhulu futhi ithuthukise ukusebenza kahle kwenjini. Kuyisinqumo esihle kakhulu se-rocket propellant.

Ukuvuza kwe-Helium: Umbulali ongabonakali emkhakheni we-aerospace

I-SpaceX ibihlelelwe ukuthi yenze umsebenzi othi “North Star Dawn” ekupheleni kuka-Agasti, kodwa ukwethulwa kwahlehliswa ngenxa yokutholwai-heliumukuvuza ngaphambi kokuqala. I-Helium idlala indima "yokukunika isandla" ku-rocket. Ikhipha umoya-mpilo owuketshezi enjinini njengesirinji.

Nokho,i-heliuminesisindo esincane samangqamuzana futhi kulula kakhulu ukuvuza, okuyingozi kakhulu kubuchwepheshe bomkhathi. Lesi sigameko siphinde sibonisa ukubaluleka kwe-helium emkhakheni we-aerospace kanye yinkimbinkimbi yokusetshenziswa kwayo.

I-Hydrogen ne-helium: izakhi eziningi kakhulu endaweni yonke

Hydrogen kanyei-heliumababona nje kuphela “omakhelwane” ku-periodic table, kodwa futhi bayizici eziningi kakhulu endaweni yonke. I-hydrogen fusion ikhipha ukushisa kube yi-helium, into eyenzeka nsuku zonke elangeni.

Uketshezi lwe-i-hydrogenfuthi i-helium isebenzisa indlela efanayo yesiqandisi, futhi amazinga okushisa azo okuncibilika aphansi kakhulu, ku- -253℃ naku -269℃ ngokulandelanayo. Lapho izinga lokushisa le-helium ewuketshezi lehla laya ku-271℃, uguquko lwe-superfluid luzokwenzeka, okuwumphumela we-quantum we-macroscopic.

Ukuthuthukiswa kobuchwepheshe obusezingeni eliphezulu obufana ne-quantum computing kuzoba nesidingo esandayo sezindawo zokushisa eziphansi kakhulu, futhi ososayensi baseShayina bazoqhubeka nokuqhubekela phambili ohambweni olunezinga lokushisa eliphansi futhi banikele kakhulu enqubekelaphambili yesayensi nezobuchwepheshe. Ngibingelele ososayensi, futhi masibheke phambili ezimpumelelweni zabo ezinhle esikhathini esizayo!
