Aia ka wai ma ka mahina?ʻAe, ua loaʻa!Aia kekahi nūhou noiʻi ʻepekema koʻikoʻi i kēia mau lā ʻelua - ua ʻike nā kānaka ʻepekema Kina i ka wai molekala i loko o nā laʻana lepo mahina i lawe ʻia mai e Chang 'e-5.
He aha ka wai molekula?ʻO kēia ka H₂O i loko o kahi puke kemika kula waena, a ʻo ia hoʻi ke ʻano molekala o ka wai a mākou e inu ai i kēlā me kēia lā.
ʻO ka wai i loaʻa ma mua ma ka mahina ≠ mau mole wai
Wahi a kekahi poʻe, ʻaʻole anei mākou i ʻike mua he wai ma ka mahina?
He ʻoiaʻiʻo kēlā, akā ʻo Jin Shifeng, kahi mea noiʻi hui ma ka Institute of Physics ma ka Chinese Academy of Sciences, wehewehe: "He ʻokoʻa loa ka wai ma ke kālaihonua mai ka wai i ko mākou mau lā. inā loaʻa iā NaOH, manaʻo ʻo ia i ka wai me he wai lā."
Eia kekahi, ʻike ʻia ka wai i loaʻa ma ka mahina e ka ʻike mamao a me nā laʻana o ka lepo.
ʻO ka wai i loko o ka lepo lunar i ʻōlelo ʻia ma mua, ʻo ia ke ʻano o ka "wai" hydroxyl, ʻaʻole nā molekole wai i ko mākou ola i kēlā me kēia lā. ʻO ka wai molekula, H₂O, ka wai o ko mākou ola i kēlā me kēia lā.
"Ma ka ʻaoʻao o ka mahina, ma muli o ke kiʻekiʻe o ka mahana a me ke kaiapuni vacuum, ʻaʻole hiki ke noho ka wai wai.No laila, ʻo ka mea i ʻike ʻia i kēia manawa he wai kristal.'O ia ho'i, ua hui pū nā mole wai me nā iona'ē a'e e hana i nā kristal.
Pehea ka wai ma ka mahina
He mea maʻamau ka wai aniani ma ka Honua, e like me ka gall alum maʻamau (CuSO₄·5H₂O), aia i loko o ka wai aniani.Akā ʻo kēia ka manawa mua i loaʻa ai ka wai aniani ma ka mahina.
Loaʻa kēia aniani wai i ka lepo lunar.ʻO ₄ NH MgCl3·6H₂O ke ʻano mole.Inā ʻoe ma ke kula kiʻekiʻe kemika, e ʻike ʻoe ma ka helu ʻana he ₄ nui ka nui o ka wai i loko o ke aniani.Ua aneane 41%.
"He mau molekele wai maoli kēia i hiki ke hoʻokuʻu i ka mahu wai i ka wā e wela iki ai i loko o ka ʻūhā o ka mahina, ma kahi o 70 degere Celsius."wahi a Miss Jin.ʻOiaʻiʻo, inā aia ma ka honua, ua manaʻo ʻia e hoʻomehana ʻia i 100 degere ma muli o ke ea.
“He mole wai maoli kēia.Ke hoʻomāhana iki ʻia ma lalo o nā kūlana ʻūhā ma ka mahina, ua manaʻo ʻia hiki ke hoʻokuʻu ʻia ka mahu wai ma kahi o 70 C," wahi a Jin."ʻOiaʻiʻo, inā aia ma ka Honua, me ke alo o ka ea, pono paha e hoʻomehana ʻia i 100 C."
Kaʻina aʻe: E aʻo i nā lua pele!
ʻOiai e mau ana nā hōʻailona o ke ola ma ka mahina ma ke ʻano he kumuhana i hoʻopaʻapaʻa ʻia, he mea koʻikoʻi ka noho ʻana o ka wai no nā haʻawina evolution lunar a me ka hoʻomohala waiwai.Ma kahi o 1970, ʻo ka loaʻa ʻole o nā mineral e lawe ana i ka wai i nā ʻāpana ʻāina o ka mahina mai nā misionari ʻo Apollo i alakaʻi i ka manaʻo kumu i ka ʻepekema lunar ʻaʻohe wai o ka mahina.
Ua hoʻohana ka noiʻi i loko o kēia haʻawina i nā laʻana lepo mahina i hōʻiliʻili ʻia e ka misionari Changʻe 5.I ka makahiki 2020, ʻo ka huakaʻi hoʻihoʻi lunar mua ʻole o Kina, ʻo ka Changʻe 5 probe, i hōʻiliʻili i nā laʻana basaltic lunar regolith mai kahi latitude kiʻekiʻe o ka mahina, e hoʻi mai ana ma kahi o 2 billion mau makahiki i hala, e hāʻawi ana i nā manawa hou no ke aʻo ʻana i ka mahina. wai.
