It is proved that the flow of silt-laden liquid is a separate flow, namely,the flow rate and flow angle of silt and liquid are nonidentical in hydraulic turbine. The greater the mass content of silt,the greater is their D-value. Moreover,it is point out that the efficiency of hydraulic turbine operated with ...

推证了含沙水流在水轮机中流动时，其沙子和液体的流动属于分离流动，即沙子和液体的运动速度和运动角是不相同的，且沙子质量越大，差值越大；并指出在水头相同时，水中含沙时水轮机的效率一般低于清水时的效率；进而分析了水轮机各过流部件的泥沙摩损规律。

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。

A new fuzzy logic based hybrid on-line minimum input power search control strategy is proposed.
