The poison error along disk tangential direction decreases the DPD signal amplitude,and the factor is 1.52T when position error is less than 25%.The radial poison error increases ...

计算结果表明：沿盘片切向的位置误差使DPD的幅值变小，在25%的范围内DPD的幅值随切向位置误差的变化系数为1.52T；沿盘片径向的位置误差使DPD产生直流偏置，在50%的范围内DPD直流偏置随径向位置误差的变化系数为3.8T。

With the implement of urbanization, there're thousands of small towns to construct. However, corresponding criterion still haven't come out ,such as water and drainage quota, which result in no standard to refer to, what's more, absenting systemic researches on variation rules and coefficients of total water and wastewater in towns. Therefore, the construction of many towns takes on luxury evidently.

随着城镇化战略的实施，目前我国有数以万计的小城镇亟待建设，但是，与小城镇建设相匹配的基础设施建设规范尚未出台，致使小城镇给排水工程建设过程中无标准可依，更缺乏小城镇用水量和排水量变化规律以及变化系数的系统研究，贪大求全、不讲科学地追求高标准的现象较为明显。
