It was found that with increasing the cathode temperature the arc velocity decreases.

实验发现，随着阴极温度的增加，电弧的后退速度下降。

By regulating the cathode temperature and applying the combined exhaust techniques, the mean time of no-failure operation of this picture tube is lengthened more than four times.

通过调整阴极温度和采用“联合排气工艺”，黑白显象管的平均寿命提高了四倍以上。因此，早期失效的问题基本得到解决。
