达赖在出国后的三十多年里，不顾事实，编造了大量诸如&'十七条协议'是武力逼迫下强加给西藏的&；&汉人屠杀了120万藏人&；&由于汉人移民，藏族在西藏成了少数&；&共产党在西藏强行对妇女实行计划生育、堕胎&；政府反对宗教自由，迫害宗教人士；藏族传统文化艺术遭到灭绝危险；西藏自然资源受到严重破坏；西藏环境受到污染等等谎言，蓄意挑拨民族关系，煽动西藏群众反对中央政府。

A method and apparatus for increasing the propelling force of pulse engine features that the fuel nozzle of pulse explosion engine is arranged in combustion chamber to close jet tube exit, and the fuel is reversely sprayed out to generate a shock wave barrier near the jet tube for preventing the airflow from flowing out of the combustion chamber, resulting in raising the pressure in combustion chamber and in turn increasing the propelling force.

本发明公开了一种提高脉冲发动机推力的方法和装置，它是通过将脉冲爆轰发动机的燃料嘴置放在燃烧室中靠近喷管出口附近，并使燃料逆向喷出，在燃烧室内靠近喷管附近形成一道阻止气流流出燃烧室的激波，激波的作用是使燃烧室压力升高，从而的到较大的推力。同时由于本发明的结构特别的简单，所以实现非常容易，并且工作效果十分显著。

The results showed that the air bubble in the coup site mainly suffered from the tensile force vertical to the impacting direction and the air bubble in the contrecoup site mainly suffered from the compressive force in the impacting direction. Since the property of tensile resistance of the brain tissue is inferior to the property of compressive resistance of the brain tissue, the injury is often easier to occur in the contrecoup site than in coup site.

实验结果表明撞击点处的气泡所受到的作用力主要为压力且来自于短轴方向，即撞击方向；对冲点处的气泡所受到的作用力主要为拉力且来自于长轴方向，即撞击方向的垂直方向。

During the pipe pushing construction of the parallel steel water pipeline of Beidu-Yanger pipeline project in Ningbo, the pushing force in main pushing power station appeared unusual increasing and the construction had to be interrupted. Through the analytical comparison between theoretical and practical pushing curves as well as the analytical comparison between the tool pipe track and the form map of pipeline resting in soil, it was found that the excessive pushing force in main pushing power station was caused by excessive deviation adjustment angle which enabled the pipeline to over bend in a short distance.

在宁波市北渡－雅戈尔原水D1800mm钢管复线工程顶管施工中，出现主顶动力站顶力异常增大的现象，影响继续顶进施工，文章针对这一情况进行分析研究，通过理论顶力曲线与实际顶力曲线以及工具管所经轨迹与管道在土层中静止时的形态图的分析比较，得出主顶动力站顶力过大是因为在纠偏过程中纠偏角度过大，使管道在短距离内过度弯曲引起的。

Almost in a moment A huge tower, at the foot of the autumn Collapsed with a rumble Unnumbered legends like pollywogs Are outpouring from its belly And flowing toward the reservoir that is going to be dry With the furtive stream A man walks toward the orchard in the autumn Is just like a stone rolling toward the tomb A man alone sits in his own library in the autumn Is just like a stone sinking into the sea And time, the time like sea water Is fatally struggling with The hour hands like the shores While we, since we invented the timekeeper Have been swathed in this vital battlefield I will drag the corpses of the autumn insects like an ant I will carry the wounded cavaliers like a wild horse I will force myself hand out the garden And then force the winter hand out flame

几乎在一瞬间一座巨塔，在秋风脚下轰然倒塌无数的传说如蝌蚪从它的腹部泻出随着隐秘的水流流向即将干涸的水库一个人在秋天走向果园就好像一块石头滚向坟墓一个人在秋天独坐书斋就好像一块石头沉入大海而时间，海水似的时间在与岸滩似的钟表指针进行着殊死的搏斗而我们，自从发明了钟表后就被裹入这致命的战场我将像蚂蚁，拖着秋虫的尸体我将像野马，驮着受伤的骑士我将逼迫自己交出果园然后，逼迫冬天交出火焰

In this thesis, an effective analysis model, named "equivalent column" model, was proposed for the wall inside the RC frames, and consideration the wall can resist axis force, moment, and shear force. The "equivalent column" model can simulate the brick wall, the RC wall as well as the wing wall. The experimental and analytical results of the RC column, pure RC frame, RC frame in-filled with RC wall, RC frame in-filled with brick wall, RC frame in-filled with wing wall, and RC column repaired by using the steel wire cables and the carbon fiber reinforced plastics were compared in the thesis.

中文摘要本研究主要分析补强前后含墙RC构架之耐震行为，目的是希望能合理有效地分析建筑物之侧向力与位移曲线，以利后续作为耐震评估之用，并考量墙体具有承受轴力、弯矩与剪力之较高自由度行为，以「等值柱」模型模拟含砖墙与含RC墙构架以及「墙柱」模型模拟含RC翼墙构架之耐震行为，分别对国内实验数据及理论分析方法-极限软化桁架模型进行比对。

Through analysis of the hydraulic shock produced in the course of reversing of the reversing valve used in the cylinder pump circuit pump, the paper shows that this hydraulic shock in the return oil pipe in the hydraulic cylinder is the result from the mutual effect due to the oil inertial force and the loading inertia force.

通过对泵—缸式液压回路在换向阀换向时产生的液压冲击的分析，表明液压缸回油管路中的液压冲击是由油液的惯性力和负载的惯性力共同作用的结果，在此基础上提出了液压缸回油管路中液压冲击的增压压力计算公式，结果可为液压系统和管路的防振减噪设计提供参考。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
