Occurrence records from 1864 locations and 34 environmental variables from Daymet datasets were gathered, four modeling methods including Logistic Regression, Classification and Regression Trees, Genetic Algorithm for Rule-Set Prediction and maximum entropy method were used to generate potential geographic distributions for Dreissena polymorpha in the continental USA. Then three statistical criteria including area under the Receiver Operating Characteristic curve, correlation and Kappa were calculated to evaluate the performance of the models, followed by analyses of major variable contributions.

The results are in good agreement with available experimental results. The entropy effect on the Gibbs free energies of 6-thioxanthine base is very small and there is little significance for the tautomeric equilibria of the base.

计算结果同已有实验结果一致。6-硫代黄嘌呤异构化的熵效应小，对互变异构平衡几乎没有显著的影响，而焓变对互变异构产生了主要的影响。

The conclusion was drawn that the tetrazine ring and amino group in the DAAT structure were in a plane and were able to build a conjugated π-bond, the calculated fre-quency and intensity were consistent with the experimental values in IR spectra, all thermal energy, thermal capacity and entropy would increase with the increase of temperature.

结果表明： DAAT分子结构中偶氮基两侧的四嗪环和氨基基本在同一个平面上，形成一个大的共轭π键；红外谱计算频率和强度与实验结果整体吻合较好；热能、热容和熵均随温度的升高而增大。

The weights are calculated by information entropy indicating the availing value of data, and the problem of weight allocation is solved.

用信息熵所反映数据本身的效用值计算指标的权重，避免了权重分配困难的问题。
