阳极丝丝位对位置测量的调制作用是制约多丝正比室沿垂直于阳极丝方向定位精度的一个主要因素。研究中利用Garfield程序，针对阳极丝间距为1、1．5和2 mm的多丝正比室结构，研究了阳极丝丝距、漂移区电场以及漂移区厚度对阳极丝调制作用的影响。结果表明，采用阳极丝感应丝等间距的结构可以有效地降低阳极丝调制作用。对于确定的阳极丝丝距和漂移区厚度，一般情况下存在着一个最优化的漂移区电场，在该电场下阳极丝的调制作用可以达到最小。

Simulation study of the anode wire modulation effect of MWPC was carried out with Garfield program . For anode wire spacing of 1,1.5 and 2 mm, the influence of the drift field and drift region thickness to the an-ode wire modulation effect was studied .Results shows that,for the structure with the anode wires and upper cathode wires were parallel and in registration , the anode modulation effect can be largely reduced if the drift field was chosen properly .
