Using the concept of the of weighted residual method and choosing the fifth B-spline as a trial function to meet the needs of boundary conditions,the mechanical problem of large deflection of a rectangular thin plate is discussed.

采用加权残值法探讨大挠度力学问题时，用5次B样条作为未知函数的试函数，使其直接满足边界条件，这种方法与传统的有限元法相比，具有未知量少，自由度少，连续性强，边界条件容易满足等优点

Experiments were carried out. The effects of defoliation on photosynthesis, dry matter translocation, grain yield and water use efficiency were investigated with different defoliation degrees and different soil water levels.

该文通过水分胁迫条件下不同程度脱叶和不同水分条件下脱叶-不脱叶的田间试验，研究了减少蒸腾器官对冬小麦光合特性、干物质转移、产量和水分利用效率的影响。

But in the complete degenerate case,the thermo-electric voltage decreases to zero,and in the complete non-degenerate case it isindependent of the statistical properties.

但是在粒子完全兼并的条件下，热电压趋于零；并且在完全非兼并条件下，热电压与统计参数g无关。

Low degree-day factors can be expected for cold-dry areas, whereas, high degree-day factors can be expected for warm-wet areas in western China.

总体看来，西部冰川的度日因子由西北向东南逐渐增大，这与中国西部冰川的气候环境变化趋势是一致的，即在干冷的气候条件下，度日因子较小；而在暖湿的气候条件下度日因子较大。

The model presents the prerequisite conditions of the delegator and the delegatee, analyzes the constraints of the delegation width and the delegation depth, and the delegation revocation based on the temporal constraints.

该模型提出了委托用户和被委托用户的资格判定条件，分析了授权宽度和授权深度的约束条件及基于时间限制的自动撤销委托授权机制。

Deliquescence of calcium sulfite under various conditions including temperature,pH,dissolving time,stirring rate and initial quantity was investigated in experiment.

亚硫酸钙的溶解浓度对氧化速率有非常重要的影响，课题主要研究CaSO3的溶解特性，描述了CaSO3在不同条件下(温度、pH、溶解时间T、搅拌速度、初始加入量等)溶解量的变化规律，进而找出CaSO3的最佳溶解条件，以达到提高氧化速率及石膏的生成率，防止堵塞和结垢的目的。

The effects of carbon source and C/N ratio on denitrification of aerobic denitrifier were investigated in the batch culture under aerobic environment.

利用间歇培养装置研究了好氧条件下丁二酸盐、乙酸盐和苹果酸盐3种不同碳源对好氧反硝化细菌X31脱氮性能的影响，并就不同碳氮比条件下菌株X31的反硝化能力展开了研究。

As an application of the above proof, we obtain at once that there is an open and dense set in the set of Ω-stable systems such that every system in the set satisfies Axiom A and the no-cycle condition (Axiom A and the strong transversality condition, respectively).

作为上述方法的一个运用，马上可以得出在Ω稳定系统的集合中有一开稠集满足公理 A 和无环性条件(对应的，公理 A 和强横截性条件)。

In fact, we point out that it is true for the density matrix of the nearest point graph.

证明了这个度数条件是三体态可分的必要条件，于是猜想它也是充分条件。

In all cases, the rate of degradation was found to be higher than the corresponding inorganic chloride yield from the parent compound. Deoxygenation was also found to increase the rate of degradation of the chlorophenols in water while degradation under alkaline condition was lower than at low to neutral pH.

试验结果表明：有机氯辐射降解的速度要比无机氯生成的速度快得多；溶液的去氧也能加快氯代苯酚的降解；在酸性到中性条件下比碱性条件下更利於有机氯裂解。

I smile at your play with that little bit of a broken twig.

我微笑着看你玩那一段小小的树枝。

They may be produced for almost any shaft angle.
