resonator length的用法和樣例：
例句
- A longer laser resonator length is benefit for laser linewidth, but harmful for single-frequency operation.
增加激光諧振腔腔長是獲得窄帶寬的有效方法，但是使實現單頻工作困難。 - The analysis shows that the measurement precision drops rapidly with length misadjustment and spot offset brought by cavity mirrors' tilt.
分析表明，腔鏡微小傾斜產生的衍射損耗的變化可以忽略，但導致的腔長變化和衰盪光斑漂移，會限制測量的精度。
