摘　　要：由于防电磁辐射面料制成服装后的屏蔽效能会因款式和暴露面积有所下降,研究服装暴露面积对屏蔽效能的影响可以为防电磁辐射类服装的研发提供参考。利用依据"开窗法"原理自行研制的独特防电磁辐射服装屏蔽效能测试系统,对不同款式的防电磁辐射服装进行效能测试和评估。结果表明:电磁屏蔽服装的屏蔽效能与服装款式和面料屏蔽效能这2个因素直接相关;在面料屏蔽效能相同的条件下,服装款式对防电磁辐射服装的屏蔽效能影响很大;西装类等暴露面积较大的屏蔽服装其屏蔽效能不佳,暴露面积过大的屏蔽服装几乎没有屏蔽效果。After shielding fabrics are made into garments, the shielding effectiveness will decrease due to different styles and exposure area of garments. This study is devoted to provide reference for anti- electromagnetic garment manufactures based on the shielding affectiveness decrease resulting from garment styles and exposure area. A unique testing system for measuring anti-electromagnetic effect of garments has been developed, and magnetic shielding effect of anti-electromagnetic garments of different styles was tested. The results indicated that the shielding efficiency of anti-electromagnetic garments is directly affected by its styles and shielding effectiveness of the fabric. When using fabrics with the same shielding effectiveness, garment style has great influence on the shielding effectiveness of anti-magnetic garments. The anti-magnetic garments with large exposure area, such as western suits, exhibit poor shielding effectiveness. The garment with excessive large exposure area has little shielding effectiveness.
