pre-displacement

Pre-displacement stopping phase and sudden types of precursor

预位移终止相与突跳型前兆类型

The source process of partial area pre-displacement is finite moving source and that of whole area pre-displacement is combination of finite moving source and instantaneous source .

局域预位移的震源过程为有限源传播，全域预位移为有限源与瞬时面源。

By comparing with the construction method of pre-displacement of cable saddle , definite the corresponding calculation methods for suspender state and its geometric of the suspender .

通过与有索鞍预偏施工方法对比，定义了此类施工方法对应的空缆状态及该状态下的空缆线形计算方法。

Because extent of partial area pre-displacement region before large earthquake is approximate to extent of whole pre-displacement region before moderate earthquake , their pre-placement amplitudes is also approximate .

由于大震局域预位移区的尺度与中强地震全域预位移区尺度相当，因而它们的预位移幅度相近，从而大震和中强震前大多数前兆异常幅度相近。

The flywheel composed of two-layer rotor is fabricated usually by extrusion of the inner rotor and the outer rotor together , so there is a pre-displacement in the interface between the two layers .

因为两层转子结构飞轮一般是由内、外两层转子通过挤压组合而成，故在两层的接触面上就有初始位移。
