| 摘 要： | 基于EMC的基本要求，针对工程上电磁屏蔽效能的繁杂运算，研究了电磁薄膜屏蔽的工程算法。结合屏蔽体吸收损耗（ABL）、反射损耗（RBL）和多重反射损耗修正因子（MUR）的推论过程，在电磁场理论、传输线理论和涡流屏蔽效应的基础上，总结了一些工程算法，极大地方便了电磁兼容技术的工程应用和实践。

| Abstract: | With the basic EMC(Electromagnetic Compatibility) demand,the engineering arithmetic for the electro-magnetic film shield is put forward here to simplify the complicated calculation for the shielding efficiency.Concerning the calculating process of the shielding object absorbing loss(ABL),reflecting loss(RBL) and the multiple reflecting loss,we summarize some engineering arithmetics basing on the electro-magnetic theory,transmitting line theory and vortex-flow shielding efficiency.The work makes the engineering application and practice more convenient. |
