For the application of 64 Codons, each step from DNA chain to mRNA chain, t RNA, ribosome, peptides, and to protein, has its specific permutable calculation model between chemical reactants and products, none of which has an objective permutable relationship with that in the 43 Table of Triplet Codes.

在生物遗传学的解释上，不预先测定给定生命体的 DNA 碱基顺序及其蛋白质的氨基酸顺序并把两者作比较，就把 DNA 和密码表两者指导合成的多肽链的氨基酸顺序称为该生命体遗传得来的氨基酸顺序，并以此将密码表称为生命的元素周期律在一切生命体中通用，是完全错误的。

In order to further understand the dependence of bioactivities on the structure of new fluorine-containing pesticidal compounds to build up significant ligand-receptor models, and to find out the pharmacophores of these analogues, 3D-QSAR analyses have been carried out with DISCO, CoMFA and Leapfrog approaches on the basis of our previous classical QSAR study. Firstly, the compounds were classified according to their structures.

为了能更深入地认识含氟新化合物作为农药的生物活性和其结构间的关系，建立有意义的药物-受体作用模型，寻找同类化合物的药效团，对合成的含氟化合物在经典QSAR方法研究的基础上，又进一步运用DISCO，CoMFA和Leapfrog方法研究了它们的三维构效关系。
