In particular, when thereis an alternating group A_5 action on a Spin 4-manifold X, we obtain: If X is smooth Spin4-manifold with non-positive signature and b_1=0, denote k=-σ/16 and m=b_2~+,then 2k+3≤m if b_2~++b_2~+≠2b_2~+(Z/A_5) and b_2~+≠0,where and are subgroups of A_5 generated by the elements s=∈A_5and t=∈A_5 respectively.

特别地，在Spin 4-流形具有非交换群A_5作用时，我们得到了：若X为光滑的具有非正符号差的Spin 4-流形，b_1=0，令k=-σ／16，m=b_2~+，如果X上具有Spin交错群A_5作用，且满足b_2~++b_2~+≠2b_2~+(X／A_5)，b_2~+≠0，则2k+3≤m，其中和分别为s=∈A_5和t=∈A_5生成的A_5的子群。

For a handsome and not an unamiable-looking man, he repelled me exceedingly: there was no power in that smooth-skinned face of a full oval shape; no firmness in that aquiline nose and small cherry mouth; there was no thought on the low, even forehead; no command in that blank, brown eye.

这样一个漂亮而且看来也并非不和蔼的男人，却使我极为讨厌。在那光滑的鹅蛋形脸蛋上没有魄力；在那个鹰钩鼻和那张樱桃小口上缺少坚毅；在那低平的额头上没有思想；在那空洞的褐色眼睛里没有控制力。

By studying the effects of mole rate of AlCl3-MEIC and fragrant chemical compound and dewater agent, electroplating aluminium bath of AlCl3-MEIC room temperature melt salt was prepared, and silvery white metallic luster , pre-pressing smooth aluminium layer is electroplated on NdFeB magnet from this solution.

4研究了AlCl_3和MEIC的摩尔比、芳香化合物及除水剂对室温熔盐电镀的影响，制备了AlCl_3-MEIC室温熔盐电沉积铝溶液，并从该溶液中电镀出了具有银白色金属光泽、致密光滑的铝镀层。

Instead, like a river streaming around a smooth boulder, light and all other forms of electromagnetic radiation would strike the cloak and simply flow around it, continuing on as if it never bumped up against an obstacle.

就像一条河流流淌过一块光滑的大石头，光线和所有其它形式的电磁辐射，一旦接触到隐身斗篷，会轻易地在斗篷周围流掉，并继续保持原来的方向，好像从未遇到过障碍物。

In some sense, everywhere-smooth models may be only approximations for the description of their slow variation part.

从某种意义上说，处处光滑的模型也许仅仅是描写它们的缓慢变化过程的一个近似。

The smooth surface provides you with a lasting grip on your device and exact cutouts allow speedy access to critical controls.

光滑的表面为您提供一个持久的抓地力您的设备和精确切口允许快速访问关键控制。

Thickness of the wing shape will be after the adjustment arm Pa, so that the rear plunger body contact with the wheel, while adjusting the tail boom is not big, flat and smooth contact with the wheel plane, which has greatly increased the rotational force at the time of Yin.

过厚的翅形体将调节臂后扒，使柱塞尾部不能与滚轮体接触，而调节臂尾部又大又不光滑的平面与滚轮体平面接触，这就大大增加了转动时的阴力。

Traveling aboard his sleek Sith Infiltrator, Maul scouted the galaxy for the missing monarch, and reported his findings to his master.

开著他光滑的西斯渗透者，达斯。魔在银河中四处搜索失踪的女王，并把发现回报给他的师父。

Having a surface marked by irregularities, protuberances, or ridges; not smooth.
