Thermal Conductivity of Air的意思|示意

The problem is the low thermal conductivity of air.

问题在于空气的热导率很低。

Microporous insulation products actually have thermal conductivity values lower than still air, due to their ability to block the three modes of heat transfer (conduction, convection and radiation).

微孔绝缘材料的热导值低于静态气流，这是由于该产品能阻碍热传递的三种方式的实现(热传导、对流和辐射)。

When the thermal conductivity of insulation layer is lower than that of air, its performance is better than that of micro bridge structure.

当复合热释电薄膜红外探测器中绝热层的热导率低于空气的热导率时，它的绝热性能优于微桥结构。

The heat conductivity, thermal capacity, pressure and resistance of water are bigger than those of the air, so a person loses more body heat in water and consumes more energy than on land.

水的导热性和热容量、压力和阻力都比空气大，人在水中体热散发相对多一些，能量消耗也大于陆上活动。

Effects of the geometric structure and thermal conductivity of the louvered fins on heat transfer and air flow friction in the radiators are evaluated in virtue of the computation program.

运用所编程序分析了散热器结构参数与材质对散热器流动阻力与散热性能的影响。

The preparing technique of doped silica aerogels was introduced in this paper. The relationships between its thermal conductivity and air pressure, temperature have been investigated.
