摘要
根据细胞电穿孔机理，当外加电场达10^6V／m，细胞膜将被击穿，内部物质外泄导致细胞灭亡．以微波生物效应、电磁场集中理论为指导，采用CST软件模拟分析2450MHz，λ／4同轴腔形式的微波灭菌装置，得出电磁场结构分布图。结果表明，当输入功率达到10。W量级时，灭菌区域满足细胞瞬态击穿的场强要求，能够实现空气的快速灭菌．
Based on the microwave biological effects, the mechanism of electroporation, and the theory of electromagnetic, a 2/4 coaxial resonant structure of microwave sterilization is simulated and analyzed with CST software in this paper The results of simulation indicates that when the input power reaches 100 W, the amplitude of the E-field in the area of sterilization will attain 106 V/m. So the cell of virus will be punctured; and the air can be sterilized fast.
