1.
In order to investigate the interference mechanism of electromagnetic pulse(EMP)coupling to secondary cable used to make signal transmitting and power transmitting of secondary equipment in substations,a three-dimensional declining finite-difference time-domain(FDTD)numerical model for EMP coupling to transmission line was developed with the electromagnetic scattering theory,and modified equ.
为了研究电磁脉冲耦合二次电缆的机理,基于电磁散射理论建立了脉冲场耦合传输线的三维倾斜时间域有限差分(FDTD)数值分析模型,推导出了三角形网格内的电磁场修正方程,进而计算了电磁脉冲激励下理想导体面上倾斜单导体传输线终端负载上的电流响应。
2.
To reduce the interference to secondary equipments caused by transient electromagnetic field due to switching operation in substations, generally the metal shields of secondary cables are connected to grounding grid at both ends.
为抑制变电站开关操作时产生的瞬态电磁场对站内二次设备的干扰,通常将二次电缆的屏蔽层双端接地。
3.
The electromagnetic interference which has an influence on the secondary cable in substations is analyzed,with comparison of the different anti-electromagnetic interference effects when secondary cable shielding grounding schemes are in different electromagnetic interference coupling,especially in the inductance coupling.

【二相──悉达太子二相】
  ﹝出佛本行集经﹞
  梵语悉达,华言顿吉,即佛幼时之名也。二相者,谓佛初生时,净饭王令相师占之。相师云:太子相好,具有轮王及成佛之相也。
  [一、轮王相],轮王相者,谓转轮圣王,亦具三十二相也。相师言:太子具足是相,若其在家,当作转轮圣王,王四天下也。(三十二相者,足安平相、千辐轮相、手指纤长相、手足柔软相、手足缦网相、足跟满足相、足趺高妙相、腨如鹿王相、手过膝相、马阴藏相、身纵广相、毛孔生青色相、身毛上靡相、身金色相、身光面各一丈相、皮肤细滑相、七处平满相、两腋满相、身如师子相、身端直相、肩圆满相、四十齿相、齿白齐密相、四牙白净相、颊车如师子相、咽中津液得上味相、广长舌相、梵音深远相、眼色如金精相、眼睫如牛王相、眉间白毫相、顶肉髻成相也。四天下,即四洲,东弗于逮、南阎浮提、西瞿耶尼、北郁单越也。)
  [二、成佛相],成佛相者,佛具三十二相。相师言:太子具足是相,若舍王位,出家求道,必得成佛,名遍十方,化导一切也。
