在研究高频电磁场与人或动物相互作用时,决定生物效应的基本物理量是在入射电磁场作用下,在生物体内部所感应电磁场的实际大小,以及由它所决定的电磁能量在体内的吸收和分布.但是要确定它们却是一个很复杂的问题.因为生物体在电磁场中所吸收的电磁能量受到很多因素的影响.如电磁场的频率、强度,受照体与电磁场极化的相对取向,受照体的外形尺寸及其内部组织结)构,周围环境因素等。尽管目前对于高 频
When studying the interaction between high-frequency electromagnetic fields and humans or animals, the basic physical quantity that determines the biological effects is the actual size of the electromagnetic field induced in the living body by the incident electromagnetic field and the absorption of the electromagnetic energy in the body determined by it However, it is a complicated problem to determine them because the electromagnetic energy absorbed by an organism in the electromagnetic field is affected by many factors, such as the frequency and intensity of the electromagnetic field and the relative orientation of polarization of the irradiated body and the electromagnetic field. The size of the body and its internal organization knot) structure, the surrounding environmental factors. Despite the current high-frequency
