摘要：In this paper we propose a new architectural switching nodes consisting of two processing nodes that follow Erlang B and Erlang C traffic respectively. The developed model is used to best utilize the given number of output channels to achieve the least blocking probability. An appropriate mathematical model has been further devised and its call blocking probability has been enunciated. Performance of the model has been evaluated for different values of blocking probabilities. It has been observed that the performance of the network is well satisfactory for different design parameters.

摘要：从设计电工实验中培养学生的思维能力刘慕圆（市工业学校）在教学中我们做的实验大部分是认知性和论证性的，学生在做实验之前，先由教师讲解实验目的、实验原理及实验步骤，学生只是在实验中按照原理图接线，按实验步骤测量、记录数据．一般受条件限制，几个同学一组，有...
