闭塞

Recent years, new technologies about train control have been introduced concerting speed raising of trains and the operation on special railways for passenger transportation. The design of application was confined in the original brainchild. New technologies simply superimpose with the pattern in existence.

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。

We analyzed 77 cases of unilateral or bilateral carotid disease which were diagnosed by TCD and cerebral angiography reported by Lindegaard 1985.The ratio of compensative blood mean velocitywith carotid disease and the identical lateral middle cerebral arterial blood mean velocity－Vm/Vmca can be used as a medium for the analysis of 81(out of 154)laterals carotid pathological changes,which was reported by Lindegaard.
