提出了一种氧气泡粒子白光散斑测速技术，与以往散斑测速方法不同的是，采用电解水时电解阳极丝上产生的氧气泡做为流场示踪粒子，用两个闪光时间间隔由数字延时电路控制的普通闪光灯做为散斑底片拍摄时的双脉冲光源，并且勿需片光技术，即可获得流场内部一个截面上的二维速度分布。

According to the character of power system, this paper analyzes the digital spectral structure and representation of a sampled periodic signal and discusses the influence to the A.

但是，这种采样技术由于时基不准确，造成的各路A/D之间存在着不容忽视的延时误差，因此必然存在着非均匀采样现象。

It can also reduce the handover frequency, hold the continuity of the correspondence and make the load of MAP balance when handovers occur.

这个模型是通过使用非固定的MAP域管理，针对单一移动节点的逻辑管理域，解决移动节点在域间切换和域内切换时的通信延时问题以达到降低切换行为的发生频率、保持切换发生时通信的连续性、使MAP负载均衡等目的。
