The pulse energy is about 200 uJ , the amplitude fluctuation is less than + 3 % , and the signal to noise ratio is better than 107 .
脉冲能量为200μJ,脉冲幅度起伏小于±3%,信噪比大于10~7。

In addition , by comparing the effect of UYJ to that of UJ , it could be speculated that the microbial agent inhibited nitrification insignificantly in tea garden soil with rich organic matter .
此外,比较UYJ和UJ处理结果可以推测:在有机质丰富的茶园中施用菌剂来抑制硝化作用的效果不显著。
