This is due to the increase of magnetic strength, make motor stator and rotor clearances between doubled, has greatly improved the cooling effect.

这是由于磁力强度的增大，使电机定子与转子之间的间隙增大了一倍，大大改善了冷却效果。

Therefore, the cooling effect of the electromagnet is an important factor to keep the magnetic field strength not decreasing rapidly.

因此，电磁铁好的冷却散热效果是保持其场强不急剧减弱的重要因素。

The effect of cooling rate and undercooling temperature on the rate and amount of dehydrogenation was studied by magnetic balance simulation method.

用磁秤模拟方法研究了冷却速度和过冷温度对镍铬钢排氢速度和排氢量的影响。
