A zafin jiki a cikin Cosmos

Yan fim da kuma almarar kimiyya marubuta suna kullum kokarin tabbatar mana da cewa mutum wanda ba zato ba tsammani samu a cikin bude sarari ba tare da wani spacesuit, za a rasa a tsaga biyu. Suna da'awar da yawan zafin jiki a sarari yake cewa wata dabba ba tare da musamman kayan aiki ba zai iya zama a cikin wani fili daga cikin talikai fiye da wata biyu. Alal misali, shi ne quite ban sha'awa da kuma rubuta a fili daya daga cikin ayyukan Artura Klarka: gwarzo, makale a bude sarari, nan take ya kashe saboda tsananin frosts da ciki matsa lamba. Duk da haka, bisa ga ka'idojin lissafin da zamani masana kimiyya, mutuwa na wani mutum a irin wannan yanayi zo ba nan da nan.

Sau da yawa ya nuna cewa mutumin, wanda ya juya daga cikin bude sarari na halittu da za a yage baya daga ciki da cika fuska kara matsa lamba. Cosmos - cikakken injin, da kuma jikin mutum ne da goyan bayan wani matsin lamba na kimanin daya yanayi. A duban farko shi iya ze cewa irin wannan rawa ne quite isa ga rai ana nan take ya kashe ta "fashewa".

A gaskiya, babu wani "fashewa" ba zai faru - jikin ta kyallen takarda ne halin da isasshen ƙarfi ne, kuma suna iya jimre da matsa lamba na daya yanayi. Maimakon sa ran dauki auku quite daban-daban: fashe capillaries cewa samar jini da fata, shi ne quite wani m sabon abu, amma ba m.

Wani dalili saboda wanda mutum zai iya mutuwa da sauri sosai a bude sararin samaniya na duniya - da sosai halittu zazzabi, wadda bisa ga wasu kimomi zuwa cikakken sifili Kelvin (-273,15 ° C). More musamman, kamar yadda mutane da tunani, ba su sani ba wani abu game da thermal fasali na interplanetary sarari. A zafin jiki a bude sarari, m kamar yadda sauti - shi ne rashin wani zazzabi. Space, bisa ga bincike, yana da wani zazzabi daidai da, shi iya ba kuma ba mai tsanani kuma sanyaya, shi ne a wani rai gabar.

Wannan gargajiyance nufi da wannan sharuddan kamar "zazzabi"? Farko - a m motsi na atoms ko kwayoyin na wanda ya kunshi duk abin da jiki. A mafi tsanani da kwayoyin matsawa, don haka, saboda haka, mafi girma da ma'aunin zafi da sanyio. Inda wani abu kamar yadda irin wannan akwai na iya zama babu tambaya na irin wannan abu, da kuma, kamar yadda da yawan zafin jiki. Space - ne kawai irin wannan wuri, inda al'amarin ne kadan. Saboda haka, da suka ce, cewa da yawan zafin jiki a sarari - shi ne mai cikakken rashin daga gare ta. Duk da haka, da jiki da suke a interplanetary sarari, da dama thermal sigogi, wanda ya dogara a kan sa na duk yiwu sigogi.

Space aka cika da kafofin daga radiation tare da mafi bambancin tsanani da kuma mita. Kuma da yawan zafin jiki a cikin sararin samaniya, daga wannan hangen zaman gaba, an fahimci matsayin total radiation makamashi a wani musamman batu a sarari.

The ma'aunin zafi da sanyio a bude sarari zai farko nuna da yawan zafin jiki, wanda ya halayyar da matsakaici, daga abin da aka cirewa, misali, daga cikin ciki na da kumbon sama jannati.
