Losses in cable sheath and armor were moved into cable conductor by thermal circuit method. 利用热路的方法将电缆金属套损耗和铠装层损耗归算到电缆导体。
Especially, the author analyzes the impact of the cable armor as the nonideal reference ground on the transmission capacity. At the end of this chapter, the author analyzes the adjusted method of FDTD, when parameters change with frequency. 特别分析了电缆铠装作为非理想参考地对传输性能的影响,最后分析了参数随频率变化时,FDTD的近似处理方法。
On the base of calculating tensile strength of submarine optical fiber cable with double armor, the optimal model of structure parameter of the SOFC is established. This model has the certain guiding sense to the structure design of the SOFC. 在计算双层铠装海底光缆拉伸强度的基础上,建立了海底光缆结构参数的优化模型,对于海底光缆的设计制造有一定的指导意义。
