| 摘 要： | 以牙根分层生物组织为例，采用近似模型，导出了单振子辐射器在圆柱状分层生物介质中的近场公式。通过数值计算，作出了电场分布的曲线，进一步分析比较了各层组织中场强的相对大小，从理论上探讨了微波治疗牙根尖周病的原理，理论分析结果与临床实践相符。

| Abstract: | The formulas of near electric field of a monopole applicator inserted in a cylindrical layer biological tissue medium for human tooth have been derived using a approximate model.The distribution of the field have been calculated numerically and displayed graphically.The amplitude values of the electric field in different layers have been further compared and the therapeutic action of microwave for periapical periodontitis has been studied.The theoretical results are in agreement with clinic practice. |
