男人的眼睛靠辐射；而女人的心靠传导。
The man's eyes by radiation; But a woman's heart by conduction.
但是由于其周围温度环境(辐射、热传导及对流状况等)与电机内部的发热规律不一致，所以不能对电动机进行有效的保护。
But because of the temperature environment (radiation, heat conduction and convection) and the internal heat of the motor is not consistent, so we can not effectively protect the motor.
在这种近似中，突出地强调了辐射热传导的作用，即认为介质中的温度分布由于热传导极强而可以近似地看成与空间无关。
In this approximation, it is assumed that the effect of radiative heat transfer would be so strong that the temperature of the medium could be regarded as uniform.
