不光滑的

If a n-dimensional unoriented cobordism class α_n containing a representative that admits a (Z_2)~k-action with fixed point set of constant codimension r,we may say that α∈is an ideal of the unoricnted cobordism ring MO_*=.

若n维未定向协边类α_n的一个代表元M~n上有不动点集为常余维数r的(Z_2)~k光滑作用，则记α_n∈J_~r.J_~=∑_n≥r_J_(n，k~r是未定向上协边环MO_+=∑_(n≥0)MO_n的理想。

In mathematical viewpoint, this kind of systems are called non-smooth dynamical systems, i.e., right-hand sides of the systems are not continuous or differentiable.

从数学的观点来看，这一类系统称为非光滑动力系统，即这些系统的右端是不连续或不可微的。

The design from the outside look like the big oval shell, the surface is glass and titanium metal, glossy shiny, seamless, and that the physical materials, such as science fiction films of the spacecraft is thought to the future rather than the past.

这个设计从外面看像椭圆形的大壳体，表层是玻璃和钛金属，光滑闪亮，浑然一体，这个形体和这种材质，像是科幻影片中的宇宙飞船，令人想到的是未来而不是过去。

A class of piecewise smooth maps with two border and three zones is derived to describe the dynamics of a current-programmed Buck converter operating in a discontinuous mode.

本文以不连续导通模式下的电流反馈型Buck变换器为例，推导出两个边界三段形式的分段光滑系统的离散映射模型。

Based on the low Reynold number and small flux model, the velocity and thickness of the liquid film outside the horizontal tube were studied.

结果表明：重力驱动在光滑横管外壁面白发形成均匀的液膜是不可能实现的，必须外加一个能产生特殊流场的气刀来改变其原有受力情况，才有可能实现均匀液膜。

However, you won't be disappointed by it's smoothy feeling andcool looking.

当然，你不会对U120EXTREME的底座失望的，因为那里看上去非常光滑，非常的COOL。

Our high-tech, satin smooth, micro-processed proprietary formula contains no mineral oil, no bees wax, no isopropyl myristate and is fragrance free.

它们的高技术，絮缎光滑感及经micro-processed properitary的方式。不包含矿物油，蜂蜡，没有异丙基myristate并且是无香味的。

RESULTS: Similar to the control, the cells in Jagged1 group displayed irregular shape with spiny or sheetlike dendrites and the cellular surface was rough. In contrast, the cells in DAPT group exhibited little dendritic processes and most of them were of round shape and with smooth surface.

结果： 与对照组相似， Jagged1组的细胞形态不规则，伪足分化和突出的片状结构较为明显，且表面粗糙；相反， DAPT组细胞的伪足不明显，多数细胞趋于圆形，表面相对光滑。

When test this equipment and pipe, peel off this material repeated use, the function don't change.

又因本材料外表有橡胶的光滑平整，以及它本身的优异性能，不需另加隔汽层，防护层，减少了施工中的麻烦，也保证了外形美观、平整。
