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。

对我国工业经济效益的考核，迄今为止采用的仍是1998年进行试算，1999年按月对外发布的工业经济效益考核指标体系，经过6年多的运行，已经趋于成熟，一些问题却也随之暴露出来。同时，随着工业经济形态向知识经济形态的转变，可持续发展问题日益被人民所重视，客观上对工业经济效益的考核提出了新的要求，故对我国现行工业经济效益考核的指标体系做如下探讨。

The experiment acquired pressure distribution and circulating rate under three fluidizing velocity (3.5m/s、4.5m/s、5.5m/s) and different media load. An experimental equation was acquired between circulating rate and the distribution of the pressure. And the relation between the circulating rate and the opening rate of the valve connecting the returner and the EHE was carefully discussed as well as the relation between the pressure of the EHE and the flow rate of the fluidizing air.

The rate of subsidence has been decreasing from area near vertex of delta to the coastal zone and some place is even rising, particularly in the early formed area. What is the different in the coastal is that the rate of subsidence is still high and can sustain a long time. This is because the land subsidence in the delta is mainly caused by the consolidation of sediments if there is no human activity. Especially in the newly formed area, Qingshuigou sub-delta, the rate of subsidence was more than 50 mm/a in the begining and now is still higher than 10 mm/a. When the newly sediments discharged by the Yellow River landed on the subaquatic delta, its load can drive the concolidation of the silt, which is on the surface of the Bohai seafloor. The rate of consolidation of the silt will be decreasing quickly in the first years, but still a long time in the later time with a slow rate.

研究结果表明：现代黄河三角洲在以宁海为顶点的河口扇形区域，近期均经历了不同程度的地表下沉过程，但是随区域地理位置和时间的不同，地表变化空间差异性比较明显；三角洲顶点附近区域的下沉速率自上世纪末开始逐渐减小，后期甚至出现轻微的抬升；滨海沿岸附近地区的地表形变特征相对比较复杂，各期叶瓣相互叠置及其各类沉积物的不均匀分配，使由沉积物自然固结压实引起的地表形变具有显著的空间差异；目前，除清水沟流路叶瓣表现为快速沉降以外，其它滨海沿岸区基本上都表现为微弱的下沉。

Different strains have different reaction to the delay of oviducts in body after animal death. After 10min delay C57BL/6 mouse oocytes have death rate of 56.5%,significantely higher than Kunming mouse (47.6%);Spontaneous activation rates were respectively 13.3% and 46.0%, C57BL/6 were obviously lower than Kunming mouse.4.
