Upon unloading at any state in the deformation, the strain does not retrace the loading curve but is reduced along an elastic unloading line. Generally speaking, the curve can be divided hook, small curve and big curve. 在变形的任一阶段卸载时,应变都不按加载曲线返回,而是沿着弹性卸载曲线下降。一般来说,曲线从球的运行路线上又可分为:勾手、曲球和大曲球。
The field retrace line which is produced by changing high voltage transformer of color TV set and its removing method 彩电更换高压包出现逆程回扫线的原因及解决办法
The article analyses the reason of retrace line which is produced by changing line output transformer of TV set and its removing method on the basic of color TV set circuit and its working principle. 本文根据彩色电视机的电路结构和工作原理,分析了更换高压包引起场逆程回扫线干扰的原因及消除该逆程回归线的方法。
