变粗糙

Wilms tumors with unfaorable histology contain anaplasia – defined as the presence of hyperchromatic, enlarged nuclei (at least 3 times as large as blastemal nuclei), and multipolar mitotic figures.

如有细胞间变则提示Wilms'瘤预后不良，所谓细胞间变，表现为染色质粗糙，胞核增大（至少是后肾胚芽细胞核的3倍大小）以及多极性有丝分裂像。

If I say my mind is crude and I try to become sensitive, the very effort to become sensitive is crudity. Please see this.

Three kinds of cutting material were selected to machine stainless steel machining experiment such as ceramic cutting tools, cermets cutting tools and coated carbide cutting tools, in which the best range of each kind of tool material was founded. For example, LT55 was suitable to be machine lCrl8Ni9Ti as the cutting speed surpasses 120m/min and have a good wearable property.(3) Surface roughness was measured under different cutting conditions. Feed rate played the most important role in impacting surface roughness, and then cutting speed.(4) Chip patterns in different cutting speed with various cutting materials were analyzed. With the increase of turning speed, chip became shorter and was easy to be broken. For instance, serration chip appeared in high sped turning stainless steel with LT55;(5) Work hardening of austenitic stainless steel was analyzed.

陶瓷刀具LT55适合在Vc=120m/min以上切削加工不锈钢，耐磨性好；③通过试验研究了不同刀具材料高速车削加工1Cr18Ni9Ti不锈钢时的表面粗糙度，其中进给量对表面粗糙度的影响最为显著，其次为切削速度；④分析了不同刀具材料在不同切削速度下加工1Cr18Ni9Ti不锈钢的切屑形态，随着车削速度的提高，切屑变短且易断屑，其中LT55陶瓷刀具切削加工时产生了锯齿状切屑；⑤分析了奥氏体不锈钢的加工硬化机理及其对刀具磨损的影响；⑥根据试验结果分析在不同切削条件下切削不锈钢的刀具磨损形式及其磨损机理。

The coexistence of the gastric mucosa thinning, dominated whitephase and prominent vascular pattern, asperous and granular changer under gastroscopy have the high specificity of CAG, intestinal metaplasia and dysplasia to their pathological diagnosis. The combination of gastroscopic and pathological examination is helpful to correct diagnosis of CAG.

胃镜直视下的黏膜变薄、皱襞变平；血管透见，白相为主；黏膜粗糙、颗粒状或结节样改变共存时对CAG、肠上皮化生及异型增生的病理诊断价值最高，但正确的诊断还需要胃镜直视与病理论断密切结合。

A fuzzy indiscernibility relation is changed into the indiscernibility relation by using a λ-cut in the rough approximation of decision classes, and an extension of VPRS method is proposed in which probabilistic rules are obtained from fuzzy decision tables.

为了从模糊近似空间中获取用于概率决策的规则，在决策类的粗糙近似中，通过应用λ-截集，将模糊不可分辨关系转化为等价关系，提出一种可从模糊决策表中获取概率规则的扩展变精度粗糙集方法。

The effects of main test parameters on the process of pitting potential of carbon steels have been studied by quasi-steady-state polarization technique and metallographical analysis technique.

采用准稳态的极化试验研究了各主要试验参数对碳钢在3%NaCl溶液中点蚀电位的影响，结果表明：3种碳钢钝化的临界pH值约为8 0 ；当T =2 0℃～35℃时，点蚀电位值Eb10 0 随温度的降低而变正；当电位变化速度慢于30mV/ 30s时，Eb10 0 随电位变化速度的减小而变负；试验面的粗糙度越大，点蚀电位越

If it becomes whiter, it contains silver, if it becomes rough and hard, it contains copper and tin, if it softens and blackens it contains lead.

如果它变白了，它含有银，如果它变得粗糙和发硬，它含有铜和锡，如果它变软和发黑，它含有铅。

Finally, the experimental setup of MR intelligent boring bar was built on the CA6140 type lathe. The experimental results show that the method can suppress the chatter efficiently and can improve the surface quality of workpieces significantly, whose roughness has decreased from 10 μm to 1.5 μm.

最后，在车床CA6140上搭建了磁流变智能镗杆的颤振抑制实验系统，实验结果表明，变结构刚度方法能够快速高效地抑制镗削过程中产生的颤振，并且使加工表面的粗糙度Ra从10μm降至1.5μm，大幅度提高了加工表面质量。

The FRP tube has a very slippery surface, with roughness rate only 0.009, which is considered as perfect slippery Tube for hydraulic. In daily usage, the wall of the tube of steel, iron or concrete are often corrosive and become rough, while the cross-winding tube can keep a clean and slippery wall surface.

玻璃钢管道内表面相当光滑，一般表面粗糙率可达0.009，几乎可以认为是&水力学光滑管&，在实际运行中，钢管、铸铁管、水泥管等的内表面，经常发生局部腐蚀，变得越来越粗糙，而往复交叉缠绕玻璃钢管道始终保持着新生管表面光滑状态。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
