本文通过两次总体设计完全相同的辐射诱发细胞微核的实验研究,从配线方程、细胞计数量到统计指标的选择依据等几个方面作了探讨。结果表明:在细胞微核的研完工作中,拟议用最小二乘方加权回归方程配线为最好。经过详细的比较,从实验资料出发提出,统计1000个有核细胞(如淋巴细胞)中的微核出现率已能反映其规律性。并且认为,统计指标中以总微核率结合有关项目综合评定为宜。 In this paper, two experiments were conducted to study the radiation-induced micronuclei in the whole design. The distribution equations, the number of cells and the selection of statistical indexes were discussed. The results show that in the research work of cell micronucleus, it is suggested that the least-squares weight regression equation is the best one. After a detailed comparison, it is proposed from the experimental data that the occurrence of micronuclei in 1000 nucleated cells (eg, lymphocytes) can reflect the regularity. And that the total indicators of micronuclei combined with the comprehensive assessment of the project appropriate.
