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

Pehea i lanakila ai nā kānaka ʻepekema Kinahydrogena me ka helium hiki ole ke hookaheia? ʻOiai ke kūlana i waena o nā mea maikaʻi loa ma ka honua? E hōʻike mākou i nā kumuhana wela e like me "Ice Arrow" a me ka helium leakage, a hele pū i ka mokuna nani o ka ʻoihana cryogenic o koʻu ʻāina.

ʻO Ice Rocket: ʻO ka hana mana o ka wai wai wai a me ka wai oxygen

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

No ke aha e koho ai i ka wai hydrogen?

He maʻalahi ke kumu: ka nui like ohydrogenhe 800 ka nui o ko ka hydrogen wai. Me ka hoʻohana ʻana i ka wahie wai, ʻo ka "huela pahu" o ka rocket e mālama i ka nui o ka manawa, a hiki ke ʻoi aku ka lahilahi o ka pūpū, i hiki ke lawe i nā ukana hou aʻe i ka lewa. ʻO ka hui pū ʻana o ka hydrogen wai a me ka oxygen wai ʻaʻole ia wale nō ka pilina o ke kaiapuni, akā hiki ke hoʻonui i ka wikiwiki wikiwiki a hoʻomaikaʻi i ka hana ʻenekini. ʻO ia ka koho maikaʻi loa no ka rocket propellant.

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

Ua hoʻomaka 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 ʻana oheliumleak ma mua o ka hoʻomaka ʻana. Hoʻokani ʻo Helium i ke kuleana o ka "hāʻawi lima iā ʻoe" ma ka rocket. Hoʻopuka ia i ka oxygen wai i loko o ka ʻenekini e like me ka syringe.

Eia naʻe,heliumHe liʻiliʻi ke kaumaha molekala a he maʻalahi loa ka leak, 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 i ke ao holoʻokoʻa

Hydrogen a meheliumʻaʻole wale nā ​​"hoa noho" i ka papaʻaina manawa, akā ʻo nā mea nui loa i 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 liquefaction ohydrogena me ka helium e hoʻohana ana i ke ʻano hoʻoheheʻe ʻana like, a he haʻahaʻa loa ko lākou wela hoʻoheheʻe ʻana, ma -253 ℃ a me -269 ℃ pakahi. Ke hāʻule ka mahana o ka helium wai i -271 ℃, e hiki mai ana kahi hoʻololi superfluid, ʻo ia ka hopena quantum macroscopic.

ʻO ka hoʻomohala ʻana i nā ʻenehana ʻokiʻoki e like me ka quantum computing e piʻi nui ana ka makemake no nā kaiapuni haʻahaʻa haʻahaʻa loa, a e hoʻomau ka poʻe ʻepekema Kina i mua i ka huakaʻi haʻahaʻa haʻahaʻa a hāʻawi hou aku i ka holomua ʻepekema a me ka ʻenehana. Aloha i ka poʻe ʻepekema, a e kakali kākou i kā lākou mau hana maikaʻi i ka wā e hiki mai ana!
