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.

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.

This study consists of three parts. Firstly the equivalently accelerative corrosive environment is determined through the analysis of statistic data of corrosion environment. Secondly the fatigue test is carried out under the constant amplitude cyclic loading for the specimens which are exposed in the corrosive environment for equivalent calendar time of zero year, 3 years, 8 years and 13 years. Four S-N curves with different corrosive time are obtained based on the fatigue experiment. Finally the regression method of S-N curves for experimental data is researched and a weighted least square fit is put forward in which the weigh of a group of test data is inversely proportional to the length of the confidence interval.
