不光滑

In the normal condition outward appearance processing should level, does not have obviously convex-concave, the surface should be smooth, the color is luminous, the long time does not change color.

正常情况下外观处理应平整，没有明显凸凹，表面应光滑，色彩光亮，长时间不变色。

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。

It is shown that the pressure distribution is a piecewise parabolic curve, and the pressure gradient can be discontinuous at the border of the slip and no-slip regions.

结果显示压力分布为分段光滑的抛物线，在滑移／非滑移边界，存在不连续的压力梯度。

Results:X-ray Barium Enema findings of AMC:No filled appendical image;widening the interval up to 2cm～3cm and forming 40～55 angles between the end of ileum and the cecum;there were half-moon impressions on the cecal paries medialis and/or the paries lateral of the end of the ileum;CT findings of AMC There were...

结果 ：AMC钡肠X线征象：阑尾不显影；盲肠与回肠末端间距增宽达 2cm～ 3cm ，并形成 4 0～ 5 5度夹角；盲肠内侧壁或/和回肠外侧壁半弧形压迹，形态固定；AMC的CT征象；右髂窝区"多个"囊性病灶，呈圆形和索条状；囊壁光滑；病灶周围结构清晰。

I picked melons according to experience, should be able to select from the following aspects: guapi smooth surface, pattern clear lines clear underside yellow, is ripe melon; while the opposite surface of hair, shiny dark, piebald, and unclear lines, is unfamiliar with the melon.

答：我挑瓜，根据以往经验，应该可以选择从以下几个方面：瓜皮表面光滑，图案清晰的线条清晰的底部黄色，是熟瓜；而相反的头发表面，有光泽黑，花斑和界限不明，不熟悉的甜瓜。

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。

The parameter space is included to construct a compound piecewise smooth map by composing previous discontinuity mappings with a Poincarémap for smooth periodic solution.

引入参数空间，将未发生碰撞的周期轨道对应的光滑映射与前面得到的不连续映射复合得到两类擦边分岔的分段映射形式。

The fabric cover (referred to as a "tea-shirt") keeps the tea hot and accentuates the sleek lines of the glass jug as well as protects the pourer's hand and the table from heat.

布套子可以使茶保温，加重了杯子上的光滑纹理，也保护了倒茶人的手和桌面不被烫坏。

The precision of integration can be evidently improved by using smooth function transition, adaptive step size change method, implicit integration and predictor corrector method. Increasing the order of the LMM may not improve the precision in this case.

采用光滑函数过渡、自适应变步长技术及隐式和预测校正等方法，可以有效地提高数值计算精度，而提高方法的阶次不能有效提高精度。

In the Uzawa algorithm, we use the HX preconditioner for the primal variable. The numerical results indicate that the new algorithm has good parallelization scalability and the iteration counts are independent of the mesh size and the jump range as for the floating subdo mains and interior cross-points.

数值实验结果表明，不论是对光滑系数还是对有无浮动子区域及有无内交叉点的跳系数情形，我们所设计的并行算法HX-Uzawa-p的迭代次数都基本不依赖于网格规模及系数跳幅，且具有很好的并行可扩展性。
