High saturation flux density can improve the work point of transformers and reduce the volume of power supply.
高饱和磁感应强度能提高变压器的工作点，缩小电源体积。

Relative humidity RH refers to the humidity saturation percentage of the air in certain volume.
相对湿度RH是指一定容积内空气的湿度饱和百分比。

Besides the authors advance a new calculation method that volume current density caused by saturation, medium is turned into equivalent surface current density.
