摘　　要：在方舱结构中,由于各种接缝及必要开口的存在,降低了方舱的屏蔽效能。为此需在缝隙或开口接触面处加装导电衬垫,以保持接触面间的电连续性,从而大大提高方舱的屏蔽效能。本文针对带有导电衬垫的方舱,提出了一种基于转移阻抗的方舱屏效计算方法。并通过算例验证这一方法是可行的。The structure of cabinet,the existence of various seams and required hatches debases the Shielding Effectiveness（SE） of cabinet.So the conductive gaskets should be installed in the interface of these seams and hatches in order to keep the interface＇s electricity-continuity which greatly improves the SE of cabinet.In this paper,a method,which is based on transfer impedance for calculating the SE of cabinet with conductive gaskets,has been put forward.And it has been proved feasible by a computing instance.
