Kev khaws cia khoom noj khoom haus txias

Kev khaws cia khoom noj khoom haus txias feem ntau yog siv los khaws cov khoom noj hauv dej, khoom noj khoom haus, thiab lwm yam.

Qhov kub ntawm ntau hom khoom noj hiav txwv txias tsis zoo ib yam, tab sis feem ntau nws yog ntawm -30 thiab -5 ° C.

Kev faib tawm ntawm cov khoom noj khoom haus txias:

1. Khoom noj hiav txwv txias cia

Qhov kub ntawm cov khoom noj hiav txwv txias cia yog txawv raws li lub sijhawm cia:

① Qhov chaw cia khoom txias nrog qhov kub thiab txias ntawm -5 ~ -12 ℃ feem ntau yog siv rau kev hloov pauv ib ntus thiab kev lag luam ntawm cov khoom noj hiav txwv tshiab.

Lub sijhawm khaws cia feem ntau yog 1-2 hnub. Yog tias cov khoom noj hiav txwv tsis raug xa tuaj hauv 1-2 hnub, cov khoom noj hiav txwv yuav tsum muab tso rau hauv lub tub yees khov sai kom khov tau sai.

② Lub tub yees khov uas muaj qhov kub thiab txias ntawm -15 ~ -20 ° C feem ntau yog siv rau kev khaws cia cov khoom noj khov ntev los ntawm lub tub yees ceev. Lub sijhawm khaws cia dav dav yog 1-180 hnub.

③ Cov chaw cia khoom txias nrog ob qhov kub saum toj no feem ntau siv thiab pom ntau hauv peb lub neej. Qhov thib ob yog chaw cia khoom txias rau khoom noj hiav txwv nrog qhov kub tsim ntawm -60 ~ -45 ℃. Qhov kub no siv tau los khaws cov ntses tuna.

Cov dej nyob hauv cov qe nqaij ntses pib khov ua cov siv lead ua thaum kub txog -1.5°C, thiab cov dej nyob hauv cov qe nqaij ntses khov ua cov siv lead ua thaum qhov kub txog -60°C.

Thaum cov ntses tuna pib khov ntawm -1.5 ° C ~ 5.5 ° C, lub cev cell ntawm cov ntses ua crystalline ntau dua, uas ua rau lub cell membrane puas tsuaj. Thaum cov ntses lub cev yaj, cov dej yooj yim ploj thiab cov saj tshwj xeeb ntawm cov ntses tuna ploj, uas ua rau nws tus nqi txo qis heev.

Yuav kom ntseeg tau tias cov ntses tuna zoo, kev khov sai siv tau rau hauv kev khaws cia txias kom khov sai kom luv lub sijhawm ntawm "-1.5 ℃ ~ 5.5 ℃ thaj chaw tsim dej khov loj dua" thiab ua kom qhov ceev khov sai dua, uas kuj yog ib txoj haujlwm tseem ceeb dua hauv kev khov ntses tuna.

2. Khoom noj hiav txwv ceev ceev-khov txias cia

Kev khaws cia khoom noj hiav txwv kom khov sai yog rau kev khov cov ntses tshiab sai sai kom tswj tau qhov tshiab ntawm kev lag luam kom nws tuaj yeem muag tau tus nqi zoo.

Lub sijhawm khov sai feem ntau yog 5-8 teev, thiab qhov kub thiab txias yog -25 ~ -30 ℃. Khov sai thiab hloov mus rau -15 ~ -20 ℃ chaw cia khoom noj ntses txias rau kev khaws cia tshiab.
