Therefore, based on a series of wheel-weighing testing data obtained by the weighbridge, the research to analyze the character of wheel-weighing testing signals and discuss relative processing methods of testing data of the overload and imbalanced is significant for theoretical research and practical application. The results can be references for the development of the high speed dynamic monitoring equipment with automatical detecting overload and imbalanced load.

因此，本文借助于列车通过这种剪力型不断轨轨道衡得到的一系列轮重检测数据，对轮重检测信号的特点及相关超偏载检测数据处理方法等进行深入分析研究，是一项有理论意义及应用价值的研究选题，研究结果可以为高速动态超偏载检测设备的研制提供参考。

After two-cluster testing,branch length testing and relative rate testing ,two sequences(Melantitta nigra and Aythya americana) of 15 Cty b sequences were deleted because thek evolutionary rate were heterogeneous. The divergence between Anseriformes and Galliformes was chosen as an anchor point. Nucleotide sequence and amino acid sequence of 13 sequences data set was used to calibrated Anatidae molecular clocks. The results indicated that amino acid sequence is better than nucleotide sequence when divergence time is calculated with two kinds of sequences. The reliable divergence time of Anatidae were estimated with """"1+2TiTv"""" model.
