慢漂移 meaning in Chinese

slow drift

By means of controlling accurately temperature of f - p cavity used in the frequency - stabilizing system of laser , the frequency stability of laser is significantly improved . especially the long - term unidirectional frequency shift is essentially overcome
从实验结果，我们得出将作为频率标准的f ? p腔精密控温与对该腔不控温对激光器振荡频率进行锁定的结果相比较，清楚看到短期稳定性有一定提高，重要是对作为稳频标准f ? p腔精密控温，消除了由于温度变化引起的频率慢漂移。
