硬化

At last,to compare differences of occurrence concerning all the imaging signs(cystic bone destructions, lucent area,"ground glass"-like density,calcification,sclerotic border,internal septation and shape abnormality of bone involved)between investigative group and control group by using Fisher Exact Test,The relative marked CT features of fibrous dysplasia at rare sites were summarized eventually.

利用Fisher确切概率法，对比囊状骨质破坏、低密度透亮区、磨玻璃样改变、骨化、边缘硬化、内部分隔、受累骨形态改变等征象在研究组、对照组出现的差异，总结研究组相对特征性CT表现。

The influences of curing agent, binder, refractory materials on the bond time of membrane serosa of ceramic-mold casting are discussed.

通过大量试验，总结出固化剂、粘结剂、耐火材料等因素对陶瓷型浆料结胶时间的影响，及在不同硬化工艺条件下陶瓷型的强度、透气性、型腔表面质量的变化规律。

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。
