粗糙

The thesis has executed system's assistant function design, It realized frame and title bar's drawing、 table drawing、 surface roughness tolerance's label、 norm symbol's label and shape tolerance's label and so on to complete rapidly.

进行系统的辅助功能设计，实现了图框和标题栏的绘制、明细表的绘制、表面粗糙度的标注、基准代号标注以及形位公差标注等辅助功能的快捷完成。

Some factors are introduced,including the effects of temperature on transverse effective electric field and surface roughness scattering,the dependence of the saturation drift velocity of the electron on transverse effective electric field and temperature,and an improved interface trapped charge and fixed oxide charge coulomb scattering model.

在新模型中，引入了横向有效电场和表面粗糙散射的温度依赖性，电子饱和漂移速度与横向有效电场和温度的关系，以及改进的界面陷阱电荷和固定氧化物电荷库仑散射模型等因素。

This leads to increased friction between mouth surfaces, and a sense of dryness or roughness.

这就增加了口内表面之间的摩擦，导致干燥或粗糙的感觉。

Bonikowskis model, the covering upper approximation operation and covering lower approximation operation are not dual to each other. William Zhu proved them determining each other, but he cannot give the quantity relation of them.

Bonikowski定义的广义覆盖粗糙集模型中，上近似算子与下近似算子不满足对偶的性质，虽然William Zhu等证明了上、下近似算子是相互确定的，但是没有给出它们之间具体的数量关系。

We compared this two model and found that the two model is coincident when dual relation was symmetric.

接着我们又用前继邻域代替等价类建立了另一个准一般关系下模糊粗糙集模型，并把两种模型进行比较，指出当二元关系满足对称性时两种模型是一致的。

In this thesis, we defined duality Fuzzy relation in a pointwise Fuzzy set by a set of duality Fuzzy point. Then we defined Fuzzy congruence and Fuzzy rough set in Fuzzy semigroups.

本文把二维模糊点作成的集合定义为一个点态化模糊集上的模糊二元关系，进一步定义模糊同余关系，并通过它又定义点态化模糊集上模糊粗糙子集，并研究了它们的一些性质。

Then, by the aid of the self-made piezoelectric vibration table, experiments of vibration drilling were done on duralumin (2A12) and stainless steel (0Cr18Ni9), and the aperture size, surface topography and surface roughness were tested.

在此基础上，利用自制的压电式振动工作台进行了硬铝和不锈钢的轴向振动钻削实验，并对孔径大小、表面形貌和表面粗糙度进行了测量。

One day, to pay homage to Albert for all that he had sacrificed, Albrecht Durer painstakingly drew his brother's abused hands with palmstogether and thin fingers stretched skyward.

为了补偿哥哥所做的牺牲，表达对哥哥的敬意，一天，Albrecht Durer下了很大的工夫把哥哥合起的粗糙的双手刻了下来。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
