在...的控制下

In part two, the optical spatiotemporal pattern in ring optic cavity is investigated. Using delay feedback with spatial perturbation method, the system shows roll, square, hexagon, homocentric circle,"honeycomb"and"snowflower" pattern with different spatial perturbation functions. Different patterns can be coexist and compete each other with the same perturbation function, which is the new character of this optical system with delay feedback.

第二部分，利用延时反馈的空间微扰方法研究了环形腔中二能级介质的光学时空斑图的控制，在不同的微扰函数作用下，出现了滚筒状、四方形、六角形、蜂窝状、同心圆以及"雪花"状等不同的斑图，并且在相同的微扰函数下出现了不同斑图之间的竞争，这种竞争是我们发现的这一具有空间微扰的延时反馈非线性光学系统光学斑图的新特征。

Also the response amplitude will be changed with the initial conditions due to the nonlinear properties of the cables.Taking the bending stiffness, cable sag and cable inclination into consideration, the space vibration control of the cables using the visco-elastic dampers in cable-stayed bridges is investigated by joining the center difference method and the state space strategy. Both the maximum modal damping ration and the optimal damper size are obtained, then the practical suggestions are proposed for the design of the dampers. The space nonlinear vibration equations of the cable-damper system are derived, and anew hybrid method for solving the cable-damper system is presented by combing the Newmark method and Pseudo-force technology. According to the known properties of the cable-damper system, the nonlinear transient responses are analyzed under all kinds of excitations. Based on the transient response, the control effectiveness of the visco-elastic dampers is further demonstrated.

综合考虑了拉索抗弯刚度、垂度的影响，研究了粘弹性阻尼器对斜拉桥拉索的空间振动控制，联合中心差分方法及状态空间法，得出了拉索面内、外振动各阶模态可能达到的最大阻尼比及相应的最优阻尼器系数，并对斜拉桥拉索的阻尼器设计提出了参考建议：考虑拉索抗弯刚度、垂度及几何非线性，导出了索-阻尼器系统的空间振动非线性方程组，结合Newmark方法及伪力(Pseudo-Force)方法，创新地提出了求解非线性方程组的杂交方法，根据拉索-阻尼器系统的阻尼特性，在各种荷载作用下，对索-阻尼器系统的非线性瞬态振动响应进行了研究，从系统响应的角度更加直接地验证了阻尼器的控制效果。

During the late Qing dynasty, owing to the invasion of the western imperialists, the Qing dynasty was forced to accept the notion of nation-state, and in order to reenforce the socail control under the circumstances that little social linkage existed between the upper and lower classes, the Qing government recognized and appropriated the cultural resources of the Beijing lower class--the belief in Pi-hsia Yuan-chun and the organizations of the pilgrims so as to control the folk society.

晚清时，西方帝国主义的侵略，使清王朝被迫有了民族国家的概念，为了加强对社会的控制，在上下层社会联系渠道不多的情况下，清政府认同并篡有了北京下层民众的文化资源--妙峰山的碧霞元君信仰及其香会组织，以此来达到控制民间社会的目的。

The simulation analysis on seismic response of seven continuous rigid-framed bridges at the two states of SMA dampers control, restrainer control, was carried out. The results show that this kind of SMA damper can availably control the seismic displacement of bridge, whose control effect for expansion joint's displacement is better than steel restrainer.

6数值分析了某七跨连续预应力混凝土刚构桥在安装SMA阻尼器和传统钢棒限位器两种情况下的地震反应，数值结果表明：两者输出控制力相同的情况下，SMA阻尼器对梁体相对位移和关键部位位移的控制效果明显优于传统钢棒限位器。

Among them, Figure 5 - 20 shows the stroke order of moves valve control circuit, in which the state, A, B 2 are in the right end of the piston cylinder.

其中， 图5- 20所示为行程阀控制的顺序动作回路，在该状态下，A、B两液压缸活塞均在右端。

Not only did they run with abandon and play a freewheeling offense led by free agent signee Steve Nash, but they were also the lead dog in a new era of pro basketball that was defined by increased hand-checking regulation (making it easier for guards to do their thing), and a slight uptick in the running game.

他们不仅仅是在进行没有禁止的疯跑而是在由新签下的自由球员史蒂夫纳什的带领下进攻端的灵活转动，自由攻击，而且他们明确增加了后卫对球控制的规定（使后卫更容易做到他们的事情）这也使太阳成为了带领篮球运动前进的领航者。

Using a single pulse solar cell tester with constant light intensity for 5ms, we have studied the performance of conventional crystalline silicon solar cell with low concentrator( 1～10 sun)and cells temperature of 15～110℃at laboratory.

结果表明，室温下常规太阳电池的最佳工作点电压V_m和光功率放大系数a随入射光强增加呈现先增后降的趋势，并且串联电阻小的电池下降速度慢，串联电阻大的电池下降速度快；温度对晶体硅太阳电池的工作电压和输出功率相当敏感；在严格控制太阳电池工作温度的条件下，串联电阻小的电池在较宽的聚光范围内可以获得良好的使用效果。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
