Feem ntau hais lus, qhov kub ntawm lub cev muaj zog yog qhov tsim nyog, uas nyob ntawm qib rwb thaiv tsev ntawm lub cev muaj zog. Yog tias nws yog Chav Kawm A, ces qhov kub ib puag ncig yog 40 ° C thiab qhov kub ntawm lub cev muaj zog lub plhaub yuav tsum tsawg dua 60 ° C.
Qhov kub txwv ntawm lub cev muaj zog kuj muaj feem cuam tshuam nrog chav kawm rwb thaiv tsev ntawm lub cev muaj zog. Piv txwv li, qhov kub txwv ua haujlwm ntawm chav kawm A yog 105 ° C, thaum qhov kub siab tshaj plaws uas tso cai ua haujlwm ntawm chav kawm A yog 90 ° C.
Yog tias lub cev muaj zog nyob rau hauv qhov ntsuas, qhov kub ntawm lub plhaub yuav tsum tsis txhob siab tshaj 80 degrees, feem ntau nyob ib puag ncig 60 lossis 70 degrees, tshwj tsis yog lub cev muaj zog twj tso kua dej.
Kev sib raug zoo ntawm qhov kub nce thiab kub thiab lwm yam:
1. Thaum qhov kub poob qis, qhov kub nce ntawm lub cev muaj zog ib txwm yuav txo qis me ntsis. Qhov no yog vim qhov tsis kam ntawm winding R txo qis thiab qhov poob tooj liab txo qis. Thaum qhov kub poob qis 1 ℃, R poob qis li 0.4%.
2. Rau cov cav uas txias nws tus kheej, kev hloov pauv kub muaj feem cuam tshuam ntau dua rau cov cav loj thiab cov cav kaw. Rau txhua qhov nce 10 ° C hauv qhov kub ib puag ncig, qhov kub nce yuav nce ntxiv 1.5 txog 3 ° C vim tias qhov poob tooj liab ntawm cov xov hlau nce ntxiv nrog rau qhov kub nce.
3. Thaum cov av noo ntawm huab cua nce 10%, qhov kub nce tuaj yeem txo tau los ntawm 0.07 ～ 0.38 ℃, nrog rau qhov nruab nrab ntawm 0.19 ℃ vim yog kev txhim kho ntawm kev coj cua sov.
4. Qhov siab kuj cuam tshuam rau qhov kub nce. Qhov siab yog 1000m ua tus qauv. Rau txhua 100m liv, qhov kub nce yuav nce 1% ntawm qhov kub nce txwv tus nqi.
