中心柱

The centrepiece was a magnificent canopied bed that once belonged to Talleyrand, the great 19th-century French diplomat.

展位中心是一架华丽的四柱床，它的故主是19世纪法国著名外交家塔列郎。

It is concluded that the diameter direction has worse macrosegregation than the catercorner direction. The strong columnar dendrite leads to positive macrosegregation. The dense crystal structure can reduce the macrosegregation of the billets.

结果表明，径向比对角线方向宏观碳偏析大；连铸坯柱状晶发达，导致中心位置附近出现较严重的碳正偏析；较致密的凝固组织有利于减轻宏观偏析；纵切面上的碳呈周期性分布。

The pressure center is the centroid of the pressure prism.

作用于平面的总压力，压力柱的形心就是压力中心。

By extending the VBG external cavity length, and inserting a convex cylindrical lens between external cavity and LDA for transmiting. Phase-locked of external cavity is achieved by tilting of Bragg Grating external cavity. Experiment studied the stability of the in-phase mode far-field output at 35A. Wavelength is locked at 802 nm. The Full-Width Half-Maximum of locked specrum narrowed to 0.2 nm and the corresponding far-field divergence angle is 1.8 mrad.

通过拉长VBG外腔腔长，在VBG外腔和LDA中间插入平凸柱面透镜，采用偏转体布拉格光栅外腔进行外腔锁相研究，在注入电流35A时，获得稳定的同相单瓣模远场输出，波长锁定在802nm，中心主瓣峰值半宽压窄到0.2nm，对应的远场发散角为1.8mrad。

The relations of electrophoresis velocity, electroosmosis velocity and electric dispersion velocity are also investigated with these expressions. The results show that this new model offers a better explanation for peak compression effect on the migration behaviour of charged solute in CEC. The retention time will be shorter by peak compression effect, which is similar to a solvent gradients process. The peak compression effect is not steady, and doesn't appear until the conditions are fitted in some special situation.

基于弛豫理论所建立的基本模型，在考虑溶质在两相中皆有可能发生正、反向迁移的情况下，得到了流出曲线一阶原点矩和二阶中心矩的理论表达式，并通过对溶质在两相中电扩散速率与电泳速率、电渗流速率关系的分析结果证实：溶质在固定相表面的电扩散行为可以使其保留变弱，出峰加快；而这种电扩散导致的超常柱效峰的出现具有不稳定性，只有在多方面因素综合影响匹配的情况下才可能出现。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
