对航天产品来说产品内存在多余物,轻者会引起电路锦路,烧毁设备,管道堵塞,启动换制系统误动作,或使运转部件卡死,密封系统不密封,会造成产品使用故障;重者会导致发动机热试车和飞行试验失败,贻误时机,或导致爆炸危及人身安全,其后果不堪设想。因此多余物是产品的心腹之患,必须彻底根除。 For aerospace products, there are excesses in the product. Lighter ones can cause circuit jewels, burn equipment, block pipes, start the system to malfunction, or make the running parts stuck. The sealing system is not sealed, causing product use failures. Severe cases can lead to failure of engine hot test and flight test, delay in timing, or cause an explosion that endangers personal safety. The consequences are unimaginable. Therefore, the excess is the product’s confidant and must be completely eradicated.
