Pane mvura pamwedzi here?Hungu, zvadaro!Pane nyaya yakakosha yekutsvagisa sainzi mazuva maviri aya - masayendisiti echiChinese akawana mvura yemamorekuru mumasampuli evhu remwedzi akadzoswa naChang 'e-5.
Chii chinonzi molecular water?Iyi iH₂O mubhuku rechikoro chepakati chechemistry, uye zvakare iri molecular formula yemvura yatinonwa muhupenyu hwezuva nezuva.

Mvura yakambowanikwa pamwedzi ≠ mamorekuru emvura

Vamwe ndovati, ko mwedzi waive nemvura here?
Icho ichokwadi, asi Jin Shifeng, mumwe mutsvakurudzi anoshanda paInstitute of Physics paChinese Academy of Sciences, anotsanangura kuti: “Mvura muzvidzidzo zvomuumbirwo wenyika yakasiyana zvikuru nemvura muupenyu hwedu hwezuva nezuva. geology inoona zvose zviri zviviri OH neH₂O semvura; kana NaOH yakawanikwa, inotora mvura semvura.
Uyezve, mvura inowanikwa pamwedzi inowanikwa nekunzwa kure uye sampuli dzepasi.
Mvura iri muvhu remwedzi wakambotaurwa kare ndiyo iyi mutsara wehydroxyl "mvura", kwete mamorekuru emvura muhupenyu hwedu hwemazuva ese. Mvura yemamorekuru, H₂O, ndiyo mvura yehupenyu hwedu hwezuva nezuva.
"Pamusoro pemwedzi, nekuda kwekupisa kwakanyanya uye nzvimbo yevacuum, mvura yemvura haigone kuvapo.Saka, izvo zvakawanikwa panguva ino icrystalline mvura.Izvi zvinoreva kuti mamorekuru emvura akabatana nemamwe maion kugadzira makristasi.

Maumbirwo emvura pamwedzi

mvura yecrystalline yakajairika paNyika, seyakajairika gall alum (CuSO₄ · 5H₂O), ine mvura ine crystalline.Asi iyi ndiyo nguva yekutanga mvura yekristaro yawanikwa paMwedzi.
Iyi aqueous crystal inowanikwa muvhu remwedzi.Iyo molecular fomu yaive ₄ NH MgCl3 · 6H₂O.Kana iwe uri muchikoro chesekondari chemistry, iwe uchaona nekuverenga kuti mvura iri mukristaro ndeye ₄ yakawanda.Zvinenge 41%.
"Aya ndiwo mamorekuru emvura chaiwo ayo, kana akadziiswa zvishoma muvacuum yemwedzi, pane inofungidzirwa 70 degrees Celsius, anogona kuburitsa mhute yemvura."Miss Jin vakadaro.Zvechokwadi, kana iri pasi, inofungidzirwa kuti inofanira kupiswa kusvika ku100 degrees nekuda kwemhepo.
“Iri imorekuru remvura chairo.Kana ichipisa zvishoma pasi pemamiriro evacuum pamwedzi, zvinofungidzirwa kuti mhute yemvura inogona kuburitswa inosvika 70 C,” akadaro Jin."Ehe, dai paive paPasi, nekuvapo kwemhepo, yaizoda kudziyisa kusvika ku100 C."

Nhanho inotevera: Dzidza makomo anoputika!

Nepo zviratidzo zvehupenyu pamwedzi zvichiripo sechinyorwa chinopokana, kuvepo kwemvura kwakakosha pazvidzidzo zvekushanduka kwemwedzi nekuvandudza zviwanikwa.Kunenge muna 1970, kusavapo kwemaminerari anotakura mvura mumasampuli evhu remwedzi kubva kumishini yeApollo kwakatungamira fungidziro yekutanga musainzi yemwedzi kuti mwedzi waive usina mvura.

Tsvagiridzo muchidzidzo ichi yakashandisa masampuli evhu remwedzi akaunganidzwa neChang'e 5 mission.Muna 2020, yekutanga yekuChina isina kurongwa yemwedzi yekudzoka semisheni, iyo Chang'e 5 probe, yakaunganidza basaltic lunar regolith samples kubva kunzvimbo yakakwirira-latitude yemwedzi, inotangira kusvika makore angangoita mabhiriyoni maviri apfuura, ichipa mikana mitsva yekudzidza kwemwedzi. mvura.
