分析了双包层光纤激光器的工作原理，简单介绍了非相干组束的原理和缺陷，重点阐述了并联主振荡相干组束方法及相干组束的优势。
The time of peak value of low frequency u wind is prior to the peak of rainfall in flood years ; ( 3 ) there are low frequency olr moves northward at low - latitude and southward at mid - latitude at the same time in flood years , the join point is between 20 - 30 n . contrarily , there is n ' t clear confluence area in drought years ; ( 4 ) the source region is about mid - latitude pacific ocean and philippines in flood years and drought years
( 2 )涝年纬向风与olr场的对应关系无论在位相还是在振幅的配置上都比较好，在长江中下游地区降水的峰值出现前期， 20 30 n纬带总是会出现西风峰值，这是与东亚夏季风的北进相联系的；而旱年时，纬向风与olr的主振荡周期总是不一致，两者的配合较差。
