This study comes from the "incontrollable problem at last stage" in blanking workpiece with non-symmetrical geometry in the bearing industry, which means the crack propagates beyond the pre-cut V-notch field at the last stage.

本文是针对轴承行业中几何非对称断料的&后失控&问题(裂纹扩展后期扩展路径超出了预制的环形V型切槽范围)提出的。

At the early 1980s, is an effective mathematic tool to deal with the uncertain or fuzzy knowledge. Rough rule theory has been widely used in information retrieval, digital library, software engineering and knowledge discovery. Its main idea includes acquisition of rough decision rules by reduction of data under the condition of keeping an invariability of classification capacity. And it basically represents a concept by a pair of approximation sets according to the partition on the given data based on the indiscernibility relation. Rough sets theory is well suited to deal with inconsistency of the rough approximations. So it is a new mathematical tool dealing with vagueness and uncertainty, and has found its applications in many areas such as AI, KDD, pattern recognition and classification and fault diagnosis.

主要完成了以下几个方面的工作：(1)对于高速移动机器人车道线跟踪问题中的规则知识获取，首先阐述了模糊逻辑系统的基本特点、工作原理和基本作法，分析了模糊规则知识获取过于依赖专家经验知识、对于每一个细节几乎都需要人工主观经验的参与、难以处理大数据集样本等方面的不足，进而阐述了粗糙集合理论的基本特点、基于粗糙集合理论的规则获取的关键技术和工作原理，为后续章节中经典粗糙集合模型的扩展及粗糙决策规则集的性能分析做好基础；(2)在经典粗糙集理论及其一般扩展的可变精度粗糙集VPRS的基础上，提出了非均匀可变精度粗糙集模型k-VPRS。

The experimental results show that:(1) the primary salt forming regions of K2SO4, Leonite, Langbenite and MgSO4H2O were observably different from those in Equilibria Phase Diagram.

实验结果表明：(1)该体系K2SO4，Leonite，langbenite和MgSO4H2O等盐能够形成初级晶核的初级成盐区与溶解平衡相区存在明显偏离，其中K2SO4成盐区域缩小，而Leonite和MgSO4H2O结晶区域均有不同程度的增大；(2)在蒸发结晶过程中，成盐晶种的存在使该盐的成盐区比初级成盐区有所扩展；(3)由于成盐区的扩展，使成盐区域出现不同程度的交错。

Experimental result makes clear:(K2SO4 of 1) this system, leonite, what the salt such as Langbenite and MgSO4.H2O can form primary nucleus is primary the area that become salt and area of deliquescent balance photograph are put in apparent deviate, among them K2SO4 narrows into saline area, and the accretion that Leonite and MgSO4.H2O crystallization area all have different rate;(2) is evaporating in crystallization process, the existence that plants into saline brilliant makes the area becoming salt of this salt is compared primary the area that become salt expands somewhat because;(3) becomes saline division patulous, salify area appears the crisscross of different level.
