摘　　要：通过理论计算研究装架精度对条纹管性能的影响.计算条纹管偏差装架时的电子轨迹;计算条纹管偏差装架时的空间调制函数以及阴极面处圆图案在最佳相面处的图像,从而研究条纹管装架过程中各电极的偏差安装对条纹管空间分辨率、图像畸变程度的影响.结果表明.各电极的同轴度以及电极筒本身的加工精度是影响条纹管性能指标尤其是空间分辨率的主要因素.The trajectory of electron was counted by computer and the data about streak tube was obtained. The MTF about streak tube when various deviations when parts of a tube are assembled,and the image on screen corresponding about the circle figure. The influences on characters of the streak tube such as spatial resolution and image distortion by position errors are discussed in this article,and then a conclusion is made that the deviations from symmetrical axis including angle error and distance error are main factors affecting the spatial resolution and image quality of streak tube. The accuracy of each part of the tube＇ s manufacturing and installation position should be ensured to improve the work performance of the tube.
