From the more than 2000 years ago, the grandson of the 19th century Prussian military theorist Carl Von Clausewitz, Chinese and foreign to many military thinkers have made a number of dialectical thinking of a military point of view.

从两千多年前的孙子，到19世纪普鲁士军事理论家克劳塞维茨，中外许多军事思想家曾提出过若干具有军事辩证法思想的观点。

Process tomography technique can provide interior behavior 2/3 dimension visualizing information in process equipment such as closed pipe, vessels and so on in real time, so it is a novel approach for two-phase flow parameters measurement.

过程层析成像技术能实时提供封闭管道、容器等过程设备内物场运动状态的二/三维可视化信息，为解决两相流参数检测问题提供了一种新的途径。

Then we use above mentioned theory to study degenerate bifurcations of codimension two in nonlinear oscillator under combined parame-tric and forcing excitation. Thereby stability problems with double zero eigenvalues can be solved.

然后利用上述理论研究了参数激励与强迫激励联合作用下非线性振动系统的余维2退化分叉，从而解决了当解具有两个零特征值时解的稳定性问题。

The mathematics models on fluid fields distribution in cold store were established in this paper.

建立了果蔬贮藏冷库内气流场的数学模型，利用计算流体力学软件FLUENT进行了三维稳态数值模拟，比较了库内两种果蔬摆放形式对气流场分布的影响。

In the teaching of central field, we should pay attention to turning the relative motion of two - body into one dimentuonal radial motion by introducing two physical concepts of reduced mass and effective potential energy, and we should also pay attention that the area law is the geometrical description of the conservation of angular momentum in the central field.

在有心力场教学中，应着重强调指出：通过引入折合质量和有效势能这两个物理量，把二体相对运动问题转化为单体沿径向的一维运动问题；以及面积定律是质心在有心力场中角动量守恒的几何描述。

I was two caps away from sending for my very own Davy Crockett hat.

我再有两个这样的瓶盖，就能寄去换顶归我自己的戴维·克罗克特帽子了。

The left ventricular internal dimension at end diastole, interventricular septal thickness at end diastole and left ventricular posterior wall thickness at end diastole were measured in the parastemal long axis view by transthoracic two-dimensional echocardiography, and to calculate left ventricular ejection fraction with Teichholtz formula and left ventricular mass with modified Devereux formula, left ventricular mass index=LVM/body surface area. From the apical four chamber and two chamber view, the basical segment and middle segment of interventricular septal, left ventricular lateral wall, anterior wall and inferior wall were obtained by tissue Doppler imaging, Regional left ventricular relaxation asynchrony index was calculated.

应用二维超声心动图在胸骨旁左心室长轴观测量左心室舒张末期内径、室间隔和左心室后壁舒张末期厚度，采用Teichholtz公式计算左心室射血分数，采用Devereux校正公式计算左心室心肌质量，左心室心肌质量指数=左心室心肌质量/体表面积；在心尖四腔心和心尖两腔心切面，应用组织多普勒成像获取室间隔、左心室侧壁、前壁和下壁的基底段和中间段8个心肌节段沿左心室长轴运动的速度频谱，测算左心室局部心肌松弛不同步性指数(regional left ventricular relaxation asynchrony index， AI)；在心尖四腔心切面，应用彩色M型多普勒超声心动图测量左心室舒张早期血流传播速度。

There are two parts in this dissertation. In part one, the reaction scattering for the H3 system is studied using three-dimensional quantum mechanical coupled channel distorted wave approximation. In part two, a new form is proposed for interaction between an atom and a diatomic molecule.

本文分两部分：第一部分用三维量子力学耦合通道扭曲波方法研究了三氢系统的反应散射；第二部分提出了一种原子与双原子分子相互作用的新形式。

The singletons are principally in museums, so Victor Pinchuk, a Ukrainian steel billionaire who acquired the record-priced diptych (and now owns a reputed 30 or so Gurskys, over 50 Hirsts and about a dozen by Koons), was willing to bid through the roof.

而《99美分》只有两种版本：单幅照片和双连画版。单幅作品主要都陈列于美术馆中，因此维克托·皮初克注释③，乌克兰的钢铁亿万富翁，心甘情愿地出天价拍下了这破高价纪录的双连画。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
