The results showed that the grain yield of winter wheat with two-irrigation was higher than that with one-irrigation with the same nitrogen application rate and method. Compared to one-irrigation,the grain number per spike in two-irrigation was higher,the 1000-grain weight was lower, the water wastage was higher, but the WUE was lower. The yield was not affected significantly by nitrogen rates and the methods. Within the nitrogen rate of 157.5-295.5kg/hm2, the lower NUPE and Nitrogen Productivity declined with nitrogen rate increasing. NHI was not lower than the others at the lowest nitrogen rate of 157.5kg/hm2. The accumulation of NO3--N in soil was significantly and positively correlated with the nitrogen application rate. NO3--N in one-irrigation was distributed mainly in the top layer (0-80cm), but it was inverse in two-irrigation.

结果表明，施氮量和施氮方式相同时春浇二水冬小麦的产量高于春浇一水，二水穗粒数较一水高，千粒重则低于一水，一水耗水量较少，水分利用效率明显高于二水；同一水分下不同施肥量及施肥方式对产量的影响差异不显著，同一施肥方式下在157.5-295.5kg/hm2范围内，施肥量越大，氮素生理效率和氮肥生产力越低，施氮157.5kg/hm2时，氮收获指数均处在最高或较高水平；土壤硝态氮残留量与施氮量呈显著正相关，成熟期一水条件下土壤中硝态氮主要集中在上层(0~80cm)，二水条件下则主要分布在中下层。

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.
