Selecting proper single valued variable separation functions in the 2+1 variable separation solutions,we construct many types of single valued coherent soliton structures such as dromion,dromion lattice,solitoff,2-solitoff,static and kinetic breather,instanton,compacton, peakon,and so on.The interactions among these coherent localized excitations including the collisions of compaction and compacton,peakon and peakon,line soliton and y-periodic soliton,dromion and dromion,dromion and solitoff,et al,are investigated analytically and graphically,and found that can be elastic and nonelastic respectively,which reveal various exotic and important nonlinear characters and interaction properties.

The method is both suitable to free vibration of nonhomogeneity beams with stepped variable cross section attached concentrative mass and forced vibration of stepped beams of nonhomogeneity with variable cross section under arbitrary loads.

这种方法也适用于非均质阶梯梁在任意谐载荷作用下的强迫振动问题以及均质阶梯梁的自由振动问题。与现有的方法相比，状态矢量法具有形式简单、适应性强等优点。

Firstly, reviewing and commenting on foreign and domestic literature about nonrecurring gains and losses; secondly, analyzing the definition and characteristics of nonrecurring gains and losses and the reason to form nonrecurring gains and losses; following, examining the research hypothesis using descriptive statistics and correlation analysis and regression of price and return model, furthermore optimizing the price model and return model through adding year variable and district variable which was divided according the return of the extraordinary items as dummy variables in the empirical research part.

文章先对国内外关于非经常性损益的研究现状进行回顾与述评；其次对我国关于非经常性损益的界定及其形成动机进行了分析；紧接着实证部分采用描述性统计、相关分析和运用价格模型和收益模型进行回归分析，对本文提出的研究假设进行检验，并加入年度虚拟变量和按照非经常项目利润率进行划分的区间虚拟变量对价格模型和收益模型进一步优化，使线性回归方程的拟合优度R2得到显著提高，利用优化后的模型对研究假设进一步检验。

The data a GetChunk call returns is assigned to variable. If Size is greater than the remaining data, the GetChunk method returns only the remaining data without padding variable with empty spaces. If the field is empty, the GetChunk method returns Null.

此方法取回的数据赋值给一个变量，若Size参数大于还需要取出的数据，则该方法返回剩余数据且并不在该变量后添加空格，若字段为空，则该方法返回NULL值。

Function relation is the relation referring to one kind of one to one correspondence between two object , is to think that another variable y can take the value that one ascertains according to the function ascertaining that when a variable x takes certain value.
