The sampling system is controlled by an adjustable program timer or by a manual pushbutton. 183. The electron arc welding power source without sampling of arc voltage is introduced in this paper. 184. By taking the improved interceptive sample method and deciding whether stops sampling after 2000 times of sampling, this method is mainly used to solve complex power grid assessment problem. 185. In order to dispel the message distortion, we must correctly arrange the sampling order of multiple analogue computer system after the sampling frequence is done. 186. This article summarizes the accuracy and coverage evaluation survey (A. C. E. survey) of the American census 2000. It includes sampling design, post-stratification, dual-system estimation and so on. 187. Because the relation between the sum of amplitude and the sampling rate owns the character of V curve, the optimal solution will be found quickly. 188. The tracking filter incorporating the radial velocity and varying sampling interval concept should have a practical application in engineering. 189.
