摘　　要：通过对楔条形阳极探测器位置灵敏坐标计算公式的推导,证明了楔形和条纹分布面积所对应的级数是等差级数.分析了楔形底宽和条纹宽度等差系数这两个设计参量对探测灵敏度的影响.研究了电极电容的电容性耦合效应对位置灵敏的影响,通过对楔条形阳极探测器坐标计算公式的修正,可在不影响分辨率的前提下有效地消除电容性耦合效应所产生的扭曲变形.It is proved that the relations among the area partitions of the wedge and strip are arithmetical by deducing the formula of coordinate for position sensitive of the wedge and strip anode detector. The effects of the two design parameters, the width of wedge bottom and the arithmetical coefficient of the strip width, on the detecting sensitivity are also analysed. The effect of capacitive coupling of the electrode capacitance on position sensitive is studied. On the condition of not affecting the resolution,the distortion arising from the capacitive coupling effect could be eliminated by adjusting the coordinate formula of the wedge and strip anode detector.
