straight buried optical cable

According to the extensive practical investigation in the army, we find that setting the monitoring marking stone of straight buried optical cable circuit or not -to set the monitor system of the optical cable jacket and the tie in box or not is a controversial question.

军内广泛的实际调查发现 ,直埋光缆线路监测标石—光缆护套及接头盒监测系统的设置与否是一个有争议的问题 。

Calculation of ampacity reduction factors for buried cables with surroundings based on FEM;

基于FEM的直埋电缆载流量与外部环境关系的计算

Finite element method is applied to solve the field with the temperature field characteristic,then the ampacity of buried cables is received after iterative computation.

根据土壤直埋电缆的温度场特性,利用有限元法对热场进行剖分和计算,经过迭代计算出有土壤直埋电缆的载流量。
