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。
In a hydraulic system, pressure fluctuations caused by various factors are likely to influence the no-failure operation of the system and even to damage the equipment. 在液压系统中,由于种种原因所造成的压力波动都会影响系统的正常运行,甚至损坏设备。
