Kev siv lub tshuab nqus tsev kom qhuav yog cov khoom siv ntub dej lossis kev daws teeb meem ntawm qhov kub qis (10 ℃ ~ - 50 ℃) hauv qab khov rau hauv cov khoom khov, tom qab ntawd nqus hauv nqus (1.3 ~ 13 mpa) los ua kom cov dej tsis muaj kua ua kom ncaj qha rau cov roj, thaum kawg ua rau cov khoom siv ntawm lub cev qhuav dej kom qhuav tshuab. Tuam Tshoj yog cov chaw tsim khoom loj ntawm API, yog li daim ntawv thov kev cia siab ntawm cov thev naus laus zis yog qhov dav heev. Txawm li cas los xij, nws yuav tsum raug sau tseg tias lub tshuab nqus tsev khov-ua kom qhuav tshuab tau nthuav dav heev hauv Suav teb. Hauv kev sib piv, nws txoj kev tshawb fawb theoretical yog qhov rov qab thiab tsis muaj zog, thiab tsis muaj ntau tus kws tshaj lij kev tshaj lij. Tsis tas li ntawd, piv nrog lwm txoj kev siv tshuab ziab hluav taws xob xws li cua tshuab kom qhuav thiab tshuaj tsuag kom qhuav, lub tshuab nqus tsev khov-qhuav kom muaj cov peev ntau dua, siv zog thiab tshuaj ntau lawm, uas txwv qhov kev txhim kho ntxiv ntawm cov thev naus laus zis no. Yog li, nws tau dhau los ua qhov teeb meem tseem ceeb tshaj plaws hauv kev ua haujlwm ntawm lub tshuab nqus tsev khov-siv tshuab kom khov kho cov kev tshawb fawb theoretical thiab paub txog kev txuag hluav taws xob, kev siv tsawg thiab txo tus nqi tsim khoom thaum xyuas kom zoo ntawm cov tshuaj.
