On the basis analysis,the method of short fibre delayed self-heterodyne were presente.
在此基础上,提出了短光纤延时自外差法,采用该方法可以在延时光纤长度远小于6倍的激光器相干长度时,消除延时自外差法因为延时时间不够导致测量精度的大幅度下降这一缺陷,为工程上实现精确测量窄线宽激光器线宽提供了行之有效的方法。
It is the thought of "Move not from outside" and "Qi has two attributes" that has brought ancient naive materialism development up to a new stage even more.
“动非自外”的内因观;“一物两体”的矛盾观等内含朴素辩证法光辉思想的提出更是将古代朴素唯物主义发展提升到一个新的阶段。
