1·This project and everything behind it was a huge challenge, he told TCH.

“这个项目和它的一切的背后是一个巨大的挑战，”他告诉T CH疗程。

2·I introduce the frequency allocation between BCCH carrier frequency and TCH, signal fading arithmetic, interference theory and the adjusting thinking of dynamic power control.

介绍了BCCH载波与TCH载波的频率配置、信号衰落算法、干扰原理、动态功率控制的调节思路，以及提高网络质量，改善小区登陆与切换性能的措施。

3·The variation coefficient of TCH was similar to CKs in plant height, chlorophyll content, panicle length, and so on. The heading duration of TCH population was longer than those of CKs.

结果表明，三交种株高、叶绿素含量、穗长等性状与单交种的变异系数差异不显著，但群体抽穗历期延长；
