| 摘 要： | 本文介绍了用双线圈测量偏转磁场的方法。文中首先导出双线圈处于x(或y)轴任意两个位置求算场参数H0、H2、H4的普遍公式。当两个小线圈的灵敏度稍有差异时,该公式仍然有效。利用沿x(或y)轴测得的一系列数据进行回归分析,求得场参数的最佳拟合值,可适用于离轴较远的距离。

| Abstract: | A double coil system has been designed for measuring the magnetic field of a deflection yoke. A general formula for calculating the field parameters of H0, H2 and H4 is derived when the measuring double coil is in any two positions on x (or y) axis. Even when there exists a small difference o f sensitivities between these two coils, the formula should stili be valid. Measurements are processed by the regression analysis along the x (or y) axis in order to obtain the optimum values for the field parameters. Measurements can be taken for regions farther away from the z-axis. |
