Secondly, the more complex inner and outer flow field is simulated around axisymmetric body with pump-jet (including no tip-clearance flow) with stator and rotor, and the numerical results are approved reasonable and inerratic by the contrast of the thrust and torque of rotor and stator to the experiment under the unself-propelled and self-propelled conditions.

紧接着，分析了推进器在非自航状态和自航状态下的性能、导管内部轴向、径向和周向速度场、压力场在相互作用中的具体形态和结构，并定性地分析了它们对水动力噪声、空泡生成以及振动的影响，为减少这些不利影响明确了解决的办法，为泵喷推进器的工程设计提供了切实可行的理论分析方法和技术思想，对工程实际具有重要的指导作用。

Results show that there is remarkable correlation between the land use types and SOM. From1981 to 2000, the content of SOM increased in the whole area mainly because of the transformation from virgin grass land to cultivated land and increase of irrigable land. The average content of SOM increased by 28% and increased from 9.64 g/kg to 12.35 g/kg. Then the household changed their land use way by driven of interest and do not increase additional input anymore.

研究结果表明：土地利用类型及土地利用方式的转换对土壤有机质含量产生重要影响。1981～2000年，荒草地向耕地的转换以及因灌溉设施的完善而引起水浇地面积的增加使得整个研究区域土壤有机质含量普遍增加，有机质含量平均值从9.64 g/kg增加到12.35 g/kg，增加了28％；在利益的驱使下，农户改变了土地利用方式，不再向种植粮食作物的土地追加投入，研究区域土壤有机质含量平均值由12.35 g/kg降低到11.46 g/kg（2000～2006年）。

Based on monochromatic light,the principle of resulting in nonreciprocal phase error that results from axial magnetic is analyzed,and the theory derivation about the actual nonreciprocal phase error is introduced.

基于单色光分析了轴向磁场产生的法拉第非互易相位差的机理，理论推导了实际的非互易相位差，给出仿真结果、分析结果和实验结果，并提出减小轴向磁场作用下的Faraday非互易相位差的主要方法是使得两个消偏器的45°误差之和(θ3+θ4)→0。

Especially, it is found that there exists three types of relative permeability of water such as concave, convex to the water saturation ax and the reversed "S" pattern. The super-low permeability reservoir is sensitive to pressure, apparent with millipore undersaturation and water blocks. In this study, a new concept of irriducible undersaturation is brought up. And a new mode to describle the process of imbibition dynamics is used to reveal and confirm the mechanism of pinhole enveloping macropore as following: pendular ring of wetting phase gathers→it fills throat→it truncates nonwejting phase . The expression of pressure distribution and the equation of oil production are deduced under conditions of non-darcy linear seepage and non-linear seepage.

尤其发现水相相对渗透率曲线存在凹向、凸向含水饱和度轴及反S形三种形式；特低渗透储层的压力敏感性强，微孔隙的欠饱和及水锁效应显著，本文研究中提出欠束缚水饱和度的概念，引用一种描述渗吸动态即湿相液环聚集→充填喉道→截断非湿相的演化过程的新方法，更深刻地揭示和证明了&小孔包围大孔&机理；推导出了非达西线性渗流和非线性渗流条件下的压力分布表达式和油井产量方程。

The strategy involves a staged combustion, where a hydrocarbon fuel added in the second, fuel-rich stage provides hydrocarbon radicals which can react with and finally reduce the NOx formed in the first, fuel-lean stage, such that NOx formed in the first stage reacts with small hydrocarbon radicals present in the second stage combustion, finally leading to N〓, and to HCN which in turn is converted to NO or N〓. Understanding of the chemistry in this second reburning stage is clearly a key to understanding and optimizing reburn technology.

目前消除NOx的主要方法是向燃烧的废气中加入某些化学物质使其重新燃烧(Selective Noncatalytic Reduction of NO processes，SNCR)，RAPRENOx过程是SNCR的主要方式之一，其实施是向燃烧产生的废气中加入异氰酸，异氰酸在高温下经一系列包括NCO的自由基反应，可以从燃烧的废气中迅速除去NOx化合物。

The pseudo-static test which subjects to horizontal load on the A-type autoclaved aerated concrete block wall was adopted. Reinforced concrete beams were set up at the upper and lower ends of the test block, and the four-bar linkage device was provided to ensure that the top of the wall was only in translatory motion, not in rotation at the level force. Hydraulic synchronous loading device was adopted to simulate the vertical load which was produced by the wall of the housing interlayer.

对A类蒸压加气混凝土砌块墙体采用水平荷载作用下的伪静力试验，试件的上下两端设置了钢筋混凝土梁，通过四连杆装置保证墙体顶部在水平力作用下只有平动而无转动，并采用同步液压加载装置模拟房屋层间墙体作用的竖向荷载。

Other features include contains 3 foam missiles, includes 3 feet of USB cable, ability to move left right up and down, prerecorded sound effects, able to download your own sound effects and add them to your program, and able to shoots up to 20 feet at a extremely fast rate.

其他功能还包括载有3泡沫导弹，其中包括3英尺的USB缆线，能力向左移动的权利，向上和向下，预先录制的声音效果，能够下载自己的声音效果，并将其添加到您的程序，并能拍摄高达20英尺在一个非常快速的速度。

I suspect (but can't tell without high-speed video) that he pronates hard through release to get the great sink he does on his fastball/changeup combinations, and I also think his slider is safer than most for the same reason.

我有点怀疑王建民出手时手掌用力向下（但这要靠高速影片才能分析），藉此让快速球或变速球获得极佳的下沈幅度。同样的理由，我认为他的滑球会比较「安全」。

Most strong earthquakes occurred on the large areomagnetic variation belts. The lateral heterogeneity of basement, which inferred by large areomagnetic variation, vailed stress concentration, earthquakes preparation and occurrence. We also get distribution of crustal thickness and continental deformation features in SYR from gravity data.

康定—绵阳一带刚性基底的阻挡造成了青藏高原下地壳物质向东的塑性流动被迫转向南东—南南东方向，进而造成了川滇菱形块体内广泛的地壳增厚，布格重力异常等值线呈向南东伸出的舌状是其地壳增厚作用的直观反映。

In the case of attack by KE Projectiles the interceptors are exploded in front of them, to tilt them downwards so that they strike their targets yawed and therefore with much reduced penetration capability.

在动能弹攻击的情况下，拦截弹在动能弹前面爆炸，并使动能弹向下倾斜，因而动能弹攻击的是一个偏斜的目标，这就大大减小了侵彻威力。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
