精神分析学受到了世界范围文学的欢迎，更激发了中国世纪初文学的兴奋，促进了缺失可继承传统的中国现代性爱文学的新生，并以最为新鲜的血液，奠基了中国现代性爱文学的新质：对人性探索的恒定兴趣和对任何束缚压抑性爱自由的大胆反叛与抗议。

The solution of zero order is taken into the first order approximate of equation of motion. Then we make the equation linearization to get the solution of first order. So is way to obtain the solution of second order.

均匀、恒定解作为0阶解代入1阶近似运动方程，使之线性化，求出1阶近似解，同理将1阶解代入2阶近似运动方程，使其线性化，求出2阶近似解。

The liquid heating and allopatric temperaturemeasuring method were adopted in the technology in order to heat the two sides of specimen with NWAS evenly and keep the temperature difference constant, and to measure the temperature of the two sides of the specimen.

该技术创造性地采用了液流加热以及异地测温的新方法，成功地解决了对微米厚度的一维纳米线阵列结构热电材料试样两侧均匀加热并保持两侧的温差恒定，以及微米厚度的试样两侧测温的难题。

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.

经过二簇检验、分枝长度检验和相对速率检验，删除2条速率不恒定的序列后，用剩余的13条序列，以鸡形目与雁形目的分歧时间(89.8MYA)为锚定点，用顺序标定法标定鸭科鸟类分子钟的分析结果表明，用&1+2TiTv&分析得到的鸭科鸟类的分歧时间比较可靠；氨基酸序列用泊松校正模型和Γ模型估计的分类单元间的分歧时间则比较一致，表明氨基酸序列更适合用于鸭科鸟类分子钟的研究；用同一基因标定分子钟时，较长序列得到的结果标准误比较小；与核苷酸序列相比，氨基酸序列更适于用作分子钟的标定。
