The statistical difference of proinsulin rather than HOMA index was found among the patients of various Gensini's score group (Gensini's score was examined as a categorical variable classified by tertile values) and significantly stenosed vessels group by means of the results of analysis of covariate variance after adjusting for age, sex and body mass index (p＜0.05), and the partial correlation coefficient between proinsulin level and Gensini's score, the number of significantly stenosed vessels after adjusting for age, sex and body mass index was 0.3156 (P＜0.01) and 0.2752 (P＜0.05) respectively. Multivariate linear regression analysis indicated that the level of proinsulin was positively correlated with the Gensini's score (P＜0.01). The results of multivariate stepwise Logistic indicated that the proinsulin was the independent risk factor for the coronary heart disease, and the odds ratio (95％ confidence interval) was 2.268 (1.253～4.105)(P=0.007), however, the HOMA was refused by the final model.

The formula was established about calculating design parameters and technological parameters of ideal strip and bent strip in the period of forming. The thesis presented how to calculate the deformed area length and contact are radius of contact deforming between two elastic bodies on condition of the friction. The calculating formula of pinch force about plate-strip pinch mill was given and the results were analyzed that friction coefficient and radius of pinch rolls are very important for determining pinch force. Moreover, the rule of deforming and stress distribution of different 〓 ratio were gained on condition that the deforming was considered to be non-uniform distribution in the gap. The differential equations were got that calculate the displacements of large deflection of elastic cantilever rectangle plate with fixed end and the formula of the Finite Strip Method was conducted to study the regularity of mid-plane displacements, deformation and stresses for elastic-plastic large deflection bend of cantilever parallelogram plate with fixed or slidable end by integrating Prandtl-Reuss equation.

However, most of the distribution of the earth pressure behind the flexible wall is of "R-shape" when the flexible wall experiencing "drum-shape "movement. Besides, the friction between the flexible wall and the soil is active during "drum-shape" movement, which decreases the deformation of the wall, lowers the application point of the resultant force and makes the development of the plastic in soil mass slow down.

研究结果表明，鼓型变位下柔性挡墙墙后土压力分布形式基本上为R字型；此外，墙土摩擦作用使墙体变位量变小，土压力系数降低，土压力合力作用点下降，塑性应变发展缓慢，从而提高墙体安全度。
