By Monte-Carlo Method the flood discharge risk is calculated with consideration of the uncertainty of flood hydrograph, and the result is compared with that without consideration of the uncertainty of flood hydrograph.

文章最后用蒙特卡洛法分别计算了此工程在考虑洪水过程不确定性和不考虑时泄洪风险值，比较二者的计算结果，后者的风险值明显大于前者，这说明，洪水过程不确定性对泄洪风险的影响不可忽略不计。

Motivated by this, we consider the global behavior of positive solutions of three-point boundary-value problems for second-order differential equations, under two different kinds of boundary-value problems, using fixed point theorem, fixed point index theorem and cone theory.

本文受到文献[7]的启发，运用不动点定理、不动点指数定理以及锥理论，分别研究了两种不同边值条件下二阶微分方程三点边值问题正解的整体性。

In chapter 4, we first discussed the existence of multiple positive solutions of the second order nonsingular Dirichlet boundary value problem for impulsive differential equations by using the fixed point index theorem in cones . Next, we presented some new existence results for singular boundary value problems for second order impulsive differential equations by using fixed point theorem in cones and Leray-Schauder nonlinear alternative theorem.

第四章我们首先利用锥不动点定理讨论了非奇异二阶脉冲微分方程狄利克莱边值问题多个正解的存在性；其次我们用锥不动点定理和Leray-Schauder型非线性抉择定理，讨论了奇异二阶脉冲微分方程狄利克莱边值问题一个及多个正解的存在性。

Test and simulation shows that the method can eliminate the unsmooth shortcoming caused by subsection low order interpolation with its inherent feature, and can meet the vision effect in inner capacity reconstruction. Further more the volume measurement error are reduced after interpolated by cubic spline without increasing any calculation, and the measurement relative error could reach 2‰ required by the system.

实验和仿真结果证明：该方法能够克服直接累加和传统的分段低次线性插值方法由于函数本身的特性，在各次间歇测量点处产生的衔接不光滑性，满足了变径内腔内表面容积重建中的视觉需求；同时在不增加计算量的前提下使得插值后容积的测量精度得到了提高，且满足2‰测量误差的要求。

This article introduced types and performance of flexible jointers in water pipeline,and put forward pipe diameter augmenting a certain value is the determinant factor whether the flexible jointer can be used or not.Different type of flexible jointer allowing corner value(namely:uneven settlement ability) is different.

介绍了输水管线柔性接口的种类和性能，指出管线直径增大到一定值后，就成为柔性接口是否可用的决定因素，不同形式柔性接口的允许转角值即适应不均匀沉降能力是不一样的。

In incomplete information system, using variable attribute rough set model, need not to evaluate missing value, we can obtain the irregular decision table without missing value.

在不完全信息系统中，使用变属性粗糙集模型，不必对缺失属性值进行估计，最后得到了不含缺失属性值的不规则决策表。

The PH value of a mixed solution of a strong acid solution with a weak monoacid, the two solutions that their PH values and volumes are equal, isn't changed.

PH值相等的强酸、一元弱酸溶液等体积混合，只要二者不发生反应，混合溶液的PH值保持不变。

In this paper, by using the cone theory and mixed monotone iterative technique, the fixed point theorems for a class of mixed monotone multivalued operators in Banach spaces without continuity and compactness are invetigated. The results presented here develop some known ones.

利用锥理论和混合单调迭代序列技术，在不要求任何紧性和连续性的情况下，证明了Banach空间中的一类混合单调集值算子不动点定理，并应用到一阶集值方程中，推广了某些已知结果。

Specific activity of NADP isocitrate dehydrogenase, methylmalonyl coenzyme A mutase and the concentration of αketoglutaric acid were higher with added soybean oil than that not added, and the concentration of succinic acid was lower than that without added soybean oil.

通过实验测定发现，发酵过程补加豆油后，异柠檬酸脱氢酶、甲基丙二酰CoA异构酶的比活以及α酮戊二酸的量均高于不补加豆油时的值，而琥珀酸的量低于不补加豆油时的值。

The contents of organic matter, total nitrogen, phosphorus, iron, manganese, copper, zinc can be increased, and the contents of hydrolizable nitrogen and their forms , Fe-P, Al-P, Ca〓-P, all organic P forms, exchangeable and organic iron, manganese, copper, zinc are increased obviously in long-term application organic manure soil. Not only the contents of soil readily oxidizable carbon, humic acid, fuluic acid, and HA/FA value are increased and Kos value decreased but also the available nitrogen, phosphorus, iron, manganese, copper, zinc are kept more high level in the organic manure soils. Long-term mulching straw has similar role with organic manure for soil nutrient except for decreasing total phosphorus, available P, N and Ca〓-P, but its fertilizer efficiency is not better than organic manure.

有机肥还具有提高土壤易氧化碳和松结态腐殖质含量，降低kos值，提高土壤HA、FA含量及其比值的作用，使土壤中有效态氮、磷、铁、锰、铜和锌含量处于中上等水平；长期秸秆还田除了不增加土壤全磷、有效氮和磷等外，对其他养分的作用效果与有机肥相似，但其肥效不如有机肥；长期氮磷化肥单施，土壤全氮和磷增加，有机质、铁、锰、铜和锌含量下降，易氧化碳、松结态腐殖质、HA和FA含量、kos和HA/FA值下降；长期不施肥土壤有机质、全氮等养分处于消耗状态。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
