But turning this push into a pull required more sophisticated optics -in Grier's case, a solenoid beam.
但是将这种推力转化为一种拉力需要更加复杂的光学，比如，在格里尔的设计中，是通过一种螺线管状光束。

After the connections are made, verify the system is working properly by turning the bias voltage on and taking a current measurement with no ion beam current.
完成电路连接之后，接通偏置电压，在没有离子束电流的情况下进行电流测量，以验证系统能够正常工作。

Constant deviation prism is a turning element which can invariably transform the propagating direction of the light beam.
