carrier oscillation meaning in English

载波振荡

Calculations indicate that the carrier phase takes effect till the time width of the pulse envelope becomes smaller than the period of the carrier oscillation , and the interpretation of this phenomenon is also presented . it is the difference between phase delay and group delay that causes the sliding between the carrier and the envelope
数值分析的结果表明，当脉宽小于光波周期时，相位的作用开始显现出来，当脉宽比光波周期长时，载波相位的作用可以忽略，并分析了相位起作用的原因，用解析的方法说明正是相延迟和群延迟之间的差别造成了光载波在脉冲包络下的滑动。
