Me ka ʻole o ka ʻenehana waihydrogena me ka waihelium, ʻo kekahi mau hale ʻepekema nui he puʻu metala ʻōpala… Pehea ke koʻikoʻi o ka hydrogen wai a me ka helium wai?

Pehea i lanakila ai nā kānaka ʻepekema Kinahydrogena me ka helium i hiki ʻole ke hoʻoheheʻe ʻia? Aia kekahi ma waena o nā mea maikaʻi loa o ka honua? E hōʻike kākou i nā kumuhana wela e like me "Ice Arrow" a me ka helium leakage, a hele pū i loko o ka mokuna nani o ka ʻoihana cryogenic o koʻu ʻāina.

ʻO ka Ice Rocket: Ka Hana Mana o ka Hydrogen Wai a me ka Oxygen Wai

ʻO mākou ka rocket lawe Long March 5 o Kina, ka "Hercules" o ka ʻoihana aerospace, "90% o ka wahie he waihydrogenma ka minus 253 degere Celsius a me ka oxygen wai ma ka minus 183 degere Celsius” - kokoke kēia i ka palena o ka mahana haʻahaʻa, a ʻo ia nō hoʻi ke kumu o ka inoa ʻo "Ice Rocket".

No ke aha e koho ai i ka hydrogen wai?

He maʻalahi ke kumu: ʻo ka nui like ohydrogenhe 800 manawa ka nui o ka hydrogen wai. Ma ka hoʻohana ʻana i ka wahie wai, mālama ka "pahu wahie" o ka rocket i kahi ākea, a hiki ke lahilahi ka pūpū, i mea e lawe ai i nā ukana i ka lewa. ʻO ka hui pū ʻana o ka hydrogen wai a me ka oxygen wai ʻaʻole wale ia he mea aloha i ke kaiapuni, akā hiki nō hoʻi ke hoʻonui i ka wikiwiki a hoʻomaikaʻi i ka pono o ka mīkini. ʻO ia ke koho maikaʻi loa no ka propellant rocket.

Helium leak: ʻO ka mea pepehi kanaka ʻike ʻole ʻia ma ke kahua aerospace

Ua hoʻonohonoho mua ʻia ʻo SpaceX e hoʻokō i ka misionari "North Star Dawn" i ka hopena o ʻAukake, akā ua hoʻopanee ʻia ka hoʻokuʻu ʻana ma muli o ka ʻike ʻia ʻana oheliumka liki ma mua o ka hoʻokuʻu ʻana. Hoʻokani ka Helium i ke kuleana o ka "hāʻawi ʻana iā ʻoe i kahi lima" ma ka rocket. Hoʻopuka ia i ka oxygen wai i loko o ka ʻenekini e like me ka syringe.

Eia naʻe,heliumhe kaumaha molekala liʻiliʻi kona a he maʻalahi loa ke kahe ʻana, he mea weliweli loa ia no ka ʻenehana lewa. Hōʻike hou kēia hanana i ke koʻikoʻi o ka helium ma ke kahua aerospace a me ka paʻakikī o kāna noi.

ʻO ka hydrogen a me ka helium: nā mea nui loa ma ke ao holoʻokoʻa

ʻO ka hydrogen a meheliumʻaʻole wale nā ​​"hoalauna" ma ka papa manawa, akā ʻo nā mea nui loa hoʻi o ke ao holoʻokoʻa. Hoʻokuʻu ka hydrogen fusion i ka wela e lilo i helium, kahi hanana e hana ʻia i kēlā me kēia lā ma ka lā.

ʻO ka hoʻoheheʻe ʻana ohydrogena hoʻohana ka helium i ke ʻano hoʻomaʻalili like, a he haʻahaʻa loa ko lākou mahana liquefaction, ma -253℃ a me -269℃. Ke hāʻule ka mahana o ka helium wai i -271℃, e hana pū ʻia kahi hoʻololi superfluid, ʻo ia ka hopena quantum macroscopic.

ʻO ka hoʻomohala ʻana o nā ʻenehana holomua e like me ka helu quantum e loaʻa ka koi nui no nā wahi mahana haʻahaʻa loa, a e hoʻomau nā kānaka ʻepekema Kina i ka holomua ma ka huakaʻi mahana haʻahaʻa a hāʻawi hou aku i ka holomua ʻepekema a me ka ʻenehana. Aloha i nā kānaka ʻepekema, a e nānā kākou i mua i kā lākou mau hoʻokō kupaianaha i ka wā e hiki mai ana!
