According to the above study results, especially the steady operation of two-sludge system（2A/O+N 2SBR）, it can be proved that denitrification and excess phosphorus uptake are relatively independent and intersectant biological processes. The overlap is that denitrifying phosphorus removing bacteriawhich possesses the two bacterial metabolisms, could utilize nitrate as an electron acceptor for phosphorus uptake. The two-sludge system can not only combined biological phosphorus removal and denitrification processes to form a process in practical wastwater treatment , but also solved the main difficulties of current single-sludge systems:①the sludge age competition between phosphorus removing bacteria and nitrifier;② the substrate competition between denitrification and dephosphatation.

以上的研究结果，尤其是时间序列的双泥生物反硝化除磷脱氮系统工艺（2A/O+N 2SBR法）的稳定运行，不仅证明了生物脱氮与生物除磷是两个既相对独立又相互交叉的生理过程，其交叉点是同时拥有硝酸盐还原性和超量吸磷这两种生化特性的细菌进行的反硝化吸磷脱氮生化反应，而且双泥系统工艺克服了常规单泥生物脱氮除磷工艺的两大问题（①聚磷菌和硝化菌的SRT相互干扰；②反硝化与生物除磷竞争VFA），同时保证了脱氮和除磷效果，排水指标达到污水综合排水标准（GB8978-1996）的一级标准，具有实际工程使用价值。

On the basis of Venigalla\'s work,we adopted two path-based algorithms, namely,gradient projection algorithm and disaggregated simplicial decomposition algorithm to solve nonadditive path cost traffic assignment problem under different engine operating modes.We compared the above two algorithms in a network example which showed that compared with the traditional Frank-Wolfe algorithm, the two path-based algorithms had a more quicker convergency while getting optimal solution,and it can obtain a satisfying solution in most cases.

2在Venigalla等人研究工作的基础上，分别采用基于路径的梯度投影算法(gradient projection，GP)和基于路径的非集计的单纯分解算法(disaggregated simplicial decomposition，DSD)来求解考虑不同发动机启动模式下，具有非可加路径费用的交通分配问题，在实例计算中比较了这两种算法的计算性能。

This paper also establishes two basic or extreme forms and a medium structural form of the supply chain by reviewing the relative literatures. It is pointed out that the complete integrated supply chain, one of the two basic forms, is noneffective, while the potential efficiency of the complete competing market or network, the another one of the two basic forms, is usually unavailable.

接着，本文确立了供应链结构的两种基本范式和中间范式，并指出，作为基本范式之一的完全一体化的供应链是无效的，而另一个基本范式—完全竞争的市场和网络范式的有效性一般不易获得，只有介于两种基本范式之间的半一体化的供应链其效率水平是可以接受的，从而也是最常见的。

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。

Although a great deal work have been done to theoretical research of beams with two cantilevers structure, we paid attention to test systems used in beams with two cantilevers mechanics test less. And school, incorporated teaching and researching, needed this small or medium octavo test system to develop teaching and researching. So joining in this development item of test system established by school, the thesis aimed to develop a set of simple, economical and applicable test system of reinforced concrete beams with two cantilevers to serve for teaching and researching, and make it a powerful supplement in structural experiment field.
