通过在针状物上施加电压，一个从液体提取离子并加速他们到一个非常高的速度然后强迫它们飞离的电场就被创造出来。

By applying voltage to the needles, an electric field is created that extracts the ions from the liquid, accelerates them at very high speeds and forces them to fly away.

离子被鞘层中的加速电场加速，以束流的形式注入到工件表面，而束流分布的情况与作用电压有着十分密切的关系。

Ions accelerated by the electric field in the sheath form a shape of beam and a flux distribution on the target surface, which are strongly dependent on the applied voltage.

基于寿命加速实验的相似理论，采用多通道变电压氯离子渗透实验装置对混凝土进行了加速寿命实验。

Based on the similarity theory of the accelerated life test, the accelerated life test of concrete was carried out with the multi-channel and adjustable-voltage chloride ion penetration test setup.
