Mathematical studies of E. coli survival curves to UV (254 nm) lead to the definition of a photoresistance parameter - the "mean survival dose" (MSD) - to compare radiation resistances of genetically related bacterial strains. Based on this MSD-parameter some repair coefficients were proposed as indicators of the relative effectiveness with which every repair system recovers radiation lesions in cells. The theoretical values calculated for the proposed coefficients are in agreement with those which were obtained from experimental data presented in the literature.
对大肠杆菌在紫外线（254纳米）照射下存活曲线的数学研究，得出了一个光抗性参数——“平均存活剂量”（MSD），用于比较基因相关细菌菌株的辐射抗性。基于这个MSD参数，提出了一些修复系数，作为每个修复系统修复细胞中辐射损伤相对有效性的指标。为这些提出的系数计算出的理论值与从文献中给出的实验数据获得的值一致。
