本文运用双区理论首次合理而系统地建立了187个甲基、烷基、环戊并、环己并多环芳烃以及胆葸系的定量结构致癌活性关系,计算与实验的符合率达95％以上。甲基多环芳烃的代谢过程中,角环湾区阳离子及亚甲基阳离子孰是“终致癌剂”的问题,目前存在着争论。根据双区理论统一了上述事实。 In this paper, for the first time, the quantitative and oncogenic activity of 187 methyl, alkyl, cyclopentaopentane, cyclohexa-PAHs, and gallbladder lines were established rationally and systematically for the first time using the two-zone theory. The coincidence rate calculated and experimentally reached 95% the above. Methyl polycyclic aromatic hydrocarbons in the metabolic process, the c? Bay area cationic and methylene cations Which is the “ultimate carcinogen” problem, there is controversy. According to the theory of dual-zone unified the above facts.
