| 摘 要： | 对细胞层次上进行的毫米波生物学效应实验中使用的培皿内的毫米波辐照剂量进行了分析．以8mm波长的毫米波为参考，通过时域有限差分法计算了两种典型构形的培皿中辐照到细胞上的毫米波功率密度和细胞对毫米波的比吸收率的数据，并对结果进行了定量表示和定性分析．计算和分析结果表明，培皿构形对辐照到细胞上的毫米波功率密度和细胞对毫米波的比吸收率在培皿内分布的作用十分显著，对实验结果会造成较大影响，在相关实验中必须考虑．

| Abstract: | An analysis is made of the millimeter-wave(MMW) dosimetry in culture dishes used in experiments on MMW biological effects at the cellular level. The finite-difference time-domain(FDTD) technique is employed to compute the MMW power density(PD) irradiated into cells in two culture dishes with typical configurations and the MMW specific absorption rate(SAR) of cells with consideration of the 8mm wavelength. A qualitative analysis as well as quantitative illustrations is carried out for the outcomes. As indicated in the results, distributions of the MMW PD irradiated into cells, the SAR of cells, and experimental results are significantly influenced by culture dish configurations which should be seriously considered in related experiments. |
