When the electrons-neutral collision frequency is less than the EM angular frequency, the collision absorption rates increase with the electron-neutral collision.

当电子-中性粒子的碰撞频率低于电磁波的角频率时，碰撞会加强电子的碰撞吸收和静电波的吸收；

Fair- haired and slight of build, Edward is not so long- limbed as Henry, less angular, and his clean- shaven cheeks are bright with the admissions of one who, despite his ambitions, has actually spent little time out of doors.

The third-generation version keeps the angular look of the current model, but the creases are less severe.
