Lub laj thawj engineering tom qab cov kev cai ntawm daim ntawv pov thawj
Cov ntawv pov thawj tsis yog cov npe teev tseg uas tsis muaj kev txwv - lawv yog cov hauv paus ntsiab lus tseem ceeb ntawm kev tsim kho uas cuam tshuam ncaj qha rau kev ua haujlwm thiab kev nyab xeeb ntawm lub kaw lus. Xav txog peb hom kev hloov pauv cua sov tseem ceeb: kev coj mus los, kev sib hloov pauv, thiab kev tawg. Hauv ib qhoCov Yeeb Nkab Nqus Tsevlos yog cov yeeb nkab cryogenic, lub qhov nqus tsev ntawm cov kav dej sab hauv thiab sab nraud tshem tawm cov cua sov hloov pauv tag nrho, txo qhov xau cua sov tag nrho ntau dua 90% piv rau cov kav dej rwb thaiv tsev ib txwm muaj. Qhov kev txo qis ntawm cov cua sov nkag mus rau hauv qhov no txhais tau tias qis dua qhov kub npau npau, txo cov nqi ua haujlwm, thiab cov txheej txheem kub ruaj khov dua.
Txawm li cas los xij, kev tswj lub tshuab nqus tsev ntawd mus ntev yog ib qho nyuaj. Txawm tias cov dej xau me me lossis cov pa tawm ntawm cov khoom sab hauv tuaj yeem ua rau lub tshuab nqus tsev ua haujlwm qeeb qeeb. Qhov ntawd yog qhov uas pebLub Tshuab Nqus Tsev Dynamiclos ua si.
