Lysis software SPSS13.0 to carry out comprehensive economic strength factor analysis and curvilinear regression analysis of kezuohouqi, the two conclusions of a lower score from overall strength factor and a higher factor scores from the level of social consumption and agriculture can be reached.

通过使用SPSS13.0统计分析软件对科左后旗经济综合实力进行因子分析和曲线回归分析，得出该旗综合实力因子得分较低，而农业及社会消费水平因子得分较高。

There were no significant correlations between food concentration and the rate of population increase of Clone B as well as the mixis rate and fertilization rate of Clone A, B and C. However, the relationships between food concentration and the rate of population increase of Clone A and C were significantly curvilinear, with the regression equation Y=0.019X2-0.209X+0.638 and Y=0.042X2-0.402X+0.852, respectively. The relationships between the food concentration and the instant rate of population increase, the mixis rate and the fertilization rate of clone D were all significantly curvilinear, with the following regression equations Y=-0.052X2+0.609X-0.667,Y=0.994X2-15.763X+73.424 and Y=-0.251X2+15.940X-15.446, respectively.

克隆B的种群瞬时增长率、种群中的混交雌体百分率和混交雌体受精率均与食物密度间无显著的相关性；克隆A和C的种群瞬时增长率与食物密度间呈曲线相关，而其种群中的混交雌体百分率和混交雌体受精率均与食物密度间无显著的相关性；克隆D的种群瞬时增长率、种群中的混交雌体百分率和混交雌体受精率均与食物密度间呈曲线相关。

A simplified method was proposed to deal with the boundary condition at the turbine unit for transient calculation. This method is based on the statistical analysis of turbine hill chart and the Eular equation for water turbines. According to the Eular equation, the basic geometry parameters of the turbine, such as guide vane opening a, blade outlet angle β2, the relative blade width of outletb2, the relative height of wicket gateb0 and the relative turbine exit radiusr2 are obtained through curvilinear regression of the water turbine hill charts.

为解决目前水轮机过渡过程计算中确定水轮机边界条件时通常使用的外特性法和内特性法的不足之处，结合这2种方法的优点，提出一种在水轮机过渡过程计算中处理水轮机边界条件的方法，即根据综合特性曲线的数据，利用统计分析方法和水轮机基本理论公式，计算水轮机基于内特性解析方程的基本参教，如出流角α、转轮出口安放角β、转轮出口相对宽度b2、导叶相对高度b0、转轮出口相对半径r2，在特性曲线上的规律。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
