Mainly used as a raw material for the manufacture of guanamine , gibuanide , various resins , trimeric cyanamide , fire retardant etc 具有去污湿润发泡乳化分散等性能,生物降解度90 。
Experiments are reduced by quantitative structure - activity relationship , then a lot of work , money and time is saved . camptothecin derivatives are a kind of prospective anticancer medication . experiments suggest support vector regression is 然后应用支持向量回归方法预测了芳香烃化合物生物降解度与喜树碱化合物抗肿瘤生物活性,得到了较好的结果。
Quantitative structure - activity relationship is a method building a statistical model . the model can quantificationally predict structure - activity relationship of molecule , and bioactivity of new molecules can be known . structure of molecule , which is described by parameters in physical chemistry , biochemistry and quantum chemistry , includes functional group , minor structure , molecular fragment , chemical composition 本文提出了一种定量构效关系的处理方法,即应用支持向量回归方法解决定量构效关系,并且应用这种方法预测了芳香烃化合物生物降解度与喜树碱化合物抗肿瘤生物活性,取得了比较令人满意的结果。
We have accomplished the software of the simulation of bioceramic degradation which can predict and calculate some parameters about the process . the degradation model put forward in this paper provide theoretic support for the 2 dimension simulation of bioceramic degradation after comparing and applying the method of grain growth 利用montecarlo方法建立了二维和三维降解模型,完成了二维降解仿真软件的编程,初步实现了对降解度的计算以及对相关参数的预测计算。
