粗糙

Based on which a new emitter signal recognition model is presented.

By extracting encrustation of histogram,and calculating partial fuzzy extent around pixels to update the fuzzy roughness.

通过提取直方图的外层，以及计算像素点周围的局部模糊程度来更新粗糙度。

In rough-set theoretic sense,the histogram correlates with the lower approximation and encrustation of histogram correlates with upper approximation.

从粗糙集理论意义上来说，直方图的外层与上近似有关，而直方图取值与下近似有关。

Endomorph - The Fat Geek; from day one this poor soul has it rough.

内胚层体型者-肥胖型；从一生下来，这种人长的就很粗糙。

Speckle is also the fundamental uncertainty factor in this kind of sensors. The analytic expression of centroid uncertainty limit is derived from the statistic of laser speckle, and it is shown that the uncertainty limit in RST, and also in anamorphic triangulation, is dependent on the solid angle subtended by entrance pupil as seen from the illuminated laser spot, the triangulation angle, as well as the laser wavelength. The influence of aberration of optical system and surface roughness are also discussed.(4) A method of getting the 3D edge characters based on the integrated vision system is studied.

重点研究了RST中的激光散斑现象，从散斑统计学的角度，首次推导了激光散斑引起的旋转对称三角法位移测量不确定度的极限，结果表明在光学粗糙表面上，该极限由投射激光波长，光学系统入瞳对投射光斑所张的立体角，以及光学系统主光轴与旋转轴的夹角确定；这一结论同样适用于其他变形成像的激光三角法。4基于RST的工作方式，研究了利用集成视觉系统的扫描移动来获得被测物体的低分辨率三维信息的方法。

I pulled the old, knotted, pine door and peeped inside, squinting my eyes to see through the floating dust and clutter of the villa's main entranceway.

我拉开那扇旧的松木门，还能感受到粗糙的树疤痕，斜着眼睛往里看。我看到的是漂浮在空中的尘埃，和别墅门廊里的凌乱摆设。

The imbalance caused by multiply of epiphyte on facial skin is different from that on hands or feet that is due to the cutin accumulates and facial skin thicken.

真菌在面部皮肤的繁衍造成角质代谢的失衡表现与手脚不会完全一致，那是由于角质堆积而使面部皮肤增厚，由于失水而变得干燥、粗糙。

It is essential to be Kinetic surface roughening process and usually occurs under far from equilibrium conditions.

薄膜生长是一个非常复杂的随机过程，它实质上是一个动力学的表面粗糙过程，通常发生在远离平衡态。

To solve this problem,the equivalence relation of rough set theory is replaced by an asymmetrical similar relation,and from this relation,an asymmetrical similar matrix is defined,then a new heuristic algorithm with less space complexity that require core and knowledge reduction based on asymmetrical similar matrix is proposed,and an example is given to confirm the validity of the algorithm.

用非对称相似关系代替粗糙集理论中的等价关系，定义了非对称相似差别矩阵，提出了基于非对称相似差别矩阵的高效求核和知识约简算法。该算法无需改变初始不完备信息系统的结构，能直接处理缺省数据。实验结果表明，新算法所获得的决策规则简洁、高效，与缺省值无关。

Rough set theory is developed based on the notion of equivalence relation,but the property of equivalence has limited its application fields,which may not provide a realistic description of real-world relationships between elements.

粗糙集理论是建立在等价关系的基础上发展起来的，但等价关系性质的应用领域是有限的，等价关系不能对现实世界中的元素关系给出客观的描述。
