cryogenic kua xws li kua nitrogen thiab kua helium tuaj yeem tau txais qhov kub qis ntawm 77K thiab 4.2k

1） cov kua dej cryogenic xws li kua nitrogen thiab kua helium tuaj yeem tau txais qhov kub qis ntawm 77K thiab 4.2k.

Qhov ntsuas kub ntawm lub pas dej ua kua tuaj yeem hloov los ntawm kev ua kom tsis sib haum ntawm qhov chaw siab dua theem kua nrog lub tshuab nqus dej. Qhov qis dua dua, qhov qis dua kub. Qhov cuam tshuam ntawm lub siab vapor siab thiab ntsuas kub ntawm kua nitrogen thiab kua helium tau muab rau hauv rooj 2 thiab daim duab 2 feem. Qhov siab yam tsawg kawg nkaus ua tiav los ntawm decompression tsis yog tsuas yog nyob ntawm lub nrawm nrawm ntawm decompression system, tab sis kuj nyob rau lub cua sov ntws mus rau lub pas dej. Txhawm rau kom tau txais qhov kub tsawg tshaj plaws, nws yog ib qho tseem ceeb uas yuav tsum sim ua kom txo qis kub.
