然后详细介绍了目前最常用的螺旋扇型静电偏转镜的基本工作原理，如参考粒子的运动轨道及偏转镜的光学性质等，讨论了螺旋线型静电偏转镜中空间电荷效应的影响。

Hybrid diwa-type orogeny which is the most common is composed of the former two types in space or in time.

在壳体构造理论下，笔者将地洼型造山运动定义为后地台阶段的构造—岩浆活化过程中各种地质作用的总称，并根据其动力来源和壳体运动方式，将地洼型造山运动划分为汇聚式、离散式和混合式，其中混合式是前两类型在时间或空间上的交替，最为常见。

Each hydraulic link of 6-DOF parallel robot is treated as an open joint-link chain. Each link's local coordinate frames is established according to the position and orientation of the component of the spatial mechanism. The stiffness and damping matrices of the link are transformed into the static gross coordinate frame through transfer matrix described by the RPY description method. The differential equation of motion of the system vibration is derived.
