Firstly , the structure of the continuous wave df / hf chemical laser is illuminated here and the principle of the prs is the emphases 首先,本文介绍了燃烧驱动df / hf化学激光器的基本结构,主要讨论了压力恢复系统的基本原理。
Meanwhile , this conclusion is further verified by the invariability of df spectrum at different delay time ( 1 - 9 ) 同一浓度下叶绿体延迟荧光光谱波形随延迟时华南师范大学硕士学位论文摘要间( l一95 )的不变性进一步证明了这一结论。
In the past few weeks , i had been noticing that my root reiserfs partition had been slowly filling up , as you can see from this " df " output 在过去的几个星期中，我注意到我的根reiserfs分区在被缓慢地填满，这可以从下面的" df "输出中看出：
This paper provides two way of df accuracy improvement : one is reducing phase error of the system and the other will be the broadening of system base 论文作者提出和分析了提高测向准确度的两个途径：一是减小测量相位误差，二是增大测量基础。
Above experimental results indicated that the 730nm component of df spectrum is the fluorescence of chlorophyll a in ps i reaction center excited by 685 nm df 上述实验结果表明叶绿体延迟荧光光谱中730nm峰是由ps所发685nm成份激发ps所产生的荧光。
