In this paper it mainly research on the test methodology of RBC which is one of the cores of CTCS-3. RBC plays an important role in guarantying the train safety and improving the transport efficiency. Moreover, there is no published specification on the test of RBC at present, so it is more important and urgent for us to do relative research about RBC to verify whether its system functions satisfy its SRS or not.

本文主要研究CTCS-3级列控系统中无线闭塞中心子系统的功能测试方法，RBC作为CTCS-3级列控系统的重要核心组成部分，在保证列车运行安全、提高列车运行效率方面起着举足轻重的作用，但是到现在为止国内外仍没有研究机构或是组织公布RBC的测试规范，这就需要我们自主研究如何去验证RBC的系统功能是否满足其系统功能需求。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
