- 摘要:
- 为实现对生物体微波非热效应的定量表征,提出通过测量微波辐射过程中生物组织的介电系数变化来定量表征微波生物非热效应。将基于二端口微波对消电路原理,通过测量S21参数以及晶状体的透光度和折射率变化,来定量研究不同辐射功率下牛晶状体的微波非热效应。研究表明S21参数在一定程度上可以用来量化的表征处于不同状态的牛晶状体。并且微波辐射功率越大,晶状体受损程度越大,S21参数变化也越大。为定量研究眼睛和微波生物非热效应提供一种研究途径,同时相关研究成果也为针对微波生物非热效应的安全标准制定提供重要的参考数据。
- Abstract:
- This project proposes to quantitatively express the nonthermal biological effects of microwave by measuring the variation of dielectric coefficient of biological tissue. Bovine lens is chosen as research objects. This project would design and development a set of dielectric coefficient measurement system and controlled microwave radiation equipment based on principle of microwave cancellation circuit. This project would set up the corresponding relation between the S21 and different radiation power. The results show that S21 could be used to quantitatively express the state of Bovine lens. Moreover, the larger the radiation power, the greater the impact on the health state of Bovine lens and S21. This project would provide a new research approach for quantitative research of nonthermal biological effects of microwave and provide important experimental and theoretical basis for the establishment of standards.
