Research on Monitoring Caesium-137 Radiation Level of Land Environment by Crustaceous Lichens

利用壳状地衣监测陆地环境中~（137）Cs活度浓度的研究

The kinetic equations of crustaceous centroid , instantaneous center and its mesh line of coupling under the condition of misalignment are established .

建立了在不对中状态下联轴器外壳质心、瞬心以及啮合线的运动方程；

Objective The activity of caesium-137 ( Bq / kg ) in the crustaceous lichens and other samples were determined to testify the feasibility , of which crustaceous lichens worked as a sensitive biology monitor to record the caesium-137 ( Bq / kg ) radiation level of land environment .

目的比较壳状地衣与其他环境样品中137Cs活度浓度差异，分析壳状地衣作为敏感的生物指示剂监测陆地环境中137Cs活度浓度的可行性。
