摘要: 建立了高功率厘米波辐照平台,测定了黄粉虫幼虫和草坪的表面温升及黄粉虫幼虫致死百分率。实验结果表明,高功率厘米波辐照过程中黄粉虫幼虫温度与辐照时间呈一定函数关系;草坪温度与辐照时间也呈一定函数关系,但两者不同。由实验结果拟合得到了辐照过程中黄粉虫幼虫表面温升与辐照时间之间的关系和黄粉虫幼虫致死百分率与辐照时间及致死百分率与温度的函数关系。实验观察了不同时间厘米波辐照对草坪的影响。观察结果表明温度超过一定数值时,厘米波辐照将损伤草坪。采用图像处理方法得到了草坪损伤的量化结果,并进一步得到了草坪损伤程度与辐照温度的函数关系。Abstract: A system of high power centimeter wave(HPCW) was built up. The temperature change of tenebrio molitor and lawn was sampled during HPCW irradiation . It is shown that the relationship between the temperature increase of tenebrio molitor and irradiation time is approximately linear, and the relationship between the temperature increase of lawn and irradiation time is nonlinear. It is also considered that the temperature of lawn increases faster than that of tenebrio molitor does during the earlier stage of irradiation. The death percentage of tenebrio molitor and injury rate of lawn irradiated by HPCW could be fitted by normal distribution. The fitting curves of relations between death rate and irradiation time and between death rate and temperature are presented.
