液體的導熱系數

今日出廠產品展示及部分報價

2、液體的導熱系數
2, the coefficient of thermal conductivity of liquid
在液體材料中,除液態金屬這個特例之外,在眾多的液體中,它們的導熱系數也是隨著溫度變化而發生變化,其中變化是呈成正比的。
In the liquid material, except in the case of liquid metal, in a large number of liquid, thermal conductivity are the changes with the temperature change, the change is proportional to the.
3、氣體的導熱系數
3, the coefficient of thermal conductivity of gas
氣體的導熱系數是隨著溫度的提高而增大,但是氣體的導熱系數一般與氣體的壓力有密切關系;總之,導熱系數表征了物質導熱本領的大小,在相關對固、液、氣三種狀態的導熱系數作了定義特征的表述之后,我們提供常見物質的有關常數(見表1-1):
Thermal conductivity of gases increases with temperature increasing, but there is a close relationship between the thermal conductivity of gas and gas pressure; in short, thermal conductivity characterization of material thermal power size, after defining characteristics stated in the related coefficient of thermal conductivity of solid, liquid, gas three states, we provide the relevant constants common substances (Table 1-1):
