根据地表热辐射传导方程,推导出一个简单易行并且精度较高的演算方法,把大气和地表的影响直接包括在演算公式中。
In this paper, a new method with simple computation and high accuracy is developed on the basis of thermal radiance transfer equation of the ground.
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.
