为了验证所建立的数学模型的可行性，本文计算了多个具有解析解或试验结果的算例，并对利用不同计算参数获得的计算结果进行了分析比较，结果表明：明满流模拟中，采用较小的狭缝宽度和较小的空间步长能够提高解的精度；跨临界流模拟中，采用删减对流项法模拟急流需要补充自由出流水位流量关系作为下游边界条件等。

Study limitations include small sample size, exclusion of several potentially eligible children because of medication-related drowsiness or refusal to participate, limited ability to generalize the results, and testing of some children more than once resulting in a learning effect or decreased pain due to healing. Older children found the game too simple and therefore not as distracting as the younger children reported it to be. Because the VR equipment was not waterproofed, pain responses could not be determined through an entire dressing change, including during wound debridement in the bathroom.

这项试验的限制因素，包括样本数很小、排除许多潜在合适的儿童，因为药物相关的嗜睡或是拒绝参与试验，而限制了这个试验结果的普遍性，而且对许多儿童进行一次以上的试验会造成一种记忆效果，或是因为复原而减少疼痛；年龄较大的儿童觉得这些游戏太过简单，因此不像对年龄较小的儿童一样，那麼地吸引人；且因为VR装备不是防水的，因此疼痛反应不能在换衣服时评估，包括於浴室时清创时。

It is could be concluded that the larger pump impeller diameter may obviously increase the efficiency of both conduit and pump system; increasing pump diameter and decreasing its rotational speed is consistent with reducing nD value.It is suitable to pump system with low head to choose lower nD value, so as a hydraulic model of axial flow pump with the better hydraulic characteristics could be obtained.

结果表明：选取较大的水泵叶轮直径将显著提高流道效率和泵装置效率；&增径降速&与降低nD值是一致的；在泵装置扬程较低的情况下，选取较小的nD值便于选用到水力性能较好的轴流泵水力模型。

Frequency offset, convergence time, phase noise and hardware cost are the most important factors for algorithm selecting. First, the carrier recovery loop is divided into two parts, frequency recovery loop and phase recovery loop.

由于载波恢复需要捕获较大的频偏范围、较短的收敛时间、较小的相位噪声和较低的硬件实现成本，所以本文从这四个方面考虑算法的选择。

The results of DDME1 and TW99 have little odds, they both give the stronger meson field potential, the smaller hyperon transition density, the harder equation of state and the bigger maximum mass; opposite to DDME1 and TW99, the GL97, TM1 and GL85 give the weaker meson field potential, the bigger hyperon transition density, the softer equation of state and the smaller maximum mass.

其中DDME1和TW99计算的结果基本相同，它们给出较强的介子场势、较小的超子转变密度、较硬的物态方程和较大的质量极限；而GL97、 TM1和GL85

The monotony and extremum theory of function are applied to prove the geometrical characteristic of error hand for 2D linear segment uncertainty ε(subscript σ) model in theory. The result shows that the error hand has the geometrical shape of "larger ends and smaller middle" or "one end larger and the other smaller". The minimum width and its exact position of the error hand are calculated too. It is proved that the minimum width position of the error hand is near the end with the smaller mean square error.

By using several thousands of point vortices and small space mesh, we obtain the large scale discrete vortices on the vortex sheet as result of the pairing of small point vortices, thus simulate the instability phenomena of the rolling-up vortex sheet.

由于使用了数千个点涡和较小的空间网格，获得了前缘涡层小涡配对出现的较大的离散涡，模拟了紧卷涡层的不稳定现象。

The calculation and experiment results show that the maximum lifting pressure performance decreases with the increase in throat diameter of channel of variable section, water flux of low pressure and pressure ratio of steam nozzle, and has its minimum value with water nozzle annular space. The coefficient of maximum lifting pressure performance may be as high as 26. In the design of steam injector, the larger pressure ratio of steam nozzle and the smaller water nozzle annular space are selected, the higher lifting pressure performance could be obtained.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
