From these result of the experiment, the dynamic modeling can be simulated effectively, when the move speed of tip is faster the shear force in the tip is bigger. In the lithography process the motion of tip influence by the pile up, it leads to the serration surface of the groove, is like the surface of actual material of the cutting process.

由加工成形与磨耗结果回馈，可有效做探针动态建模，并模拟出，当探针移动的速度越快时，针尖所承受的剪应力越大，并且在蚀刻过程中，针尖受表面堆积物的影响，导致沟槽表面类似锯齿形的蚀刻表面与实际加工之情形相似。

To resolve the design difficulties caused by small cross-section, low height of the bridge structure, the key technique problem to the bridge structure should be carried on research and analysis, such as whole calculation model, considering foundation combined action , the reasonable rigidity match to the joint of the girder and pier ,inner force redistribution caused by the system conversion ,the forecast to long-term deformation after building , stress analysis and tectonic steel bar of the anchored serration block , the influence of foundation settlement and anti- earthquake measures . To acquire feasible and reasonable technique parameters and provide the full design basis, according to analytical results adjust and optimize the bridge structure design.

为解决桥梁结构要求截面小，高度低等带来的设计困难，需对该结构的关键技术问题如考虑基础共同作用的整体计算模型、梁墩间的合理刚度匹配、体系转换产生的内力重分布、成桥后的长期变形预测、锚下锯齿块应力分析及配筋构造、基础沉降影响及抗震措施等进行研究分析，以获得技术可行、经济合理的技术参数，为设计提供充分的依据，根据分析结果调整优化桥梁结构设计。

The interface between pure Mo and interphase is smooth cycle, and that between pure W and interphase is discontinue one. The boundaries between interphase and TiAl matrix in both composites are serrated in as-cast condition, and the serration disappeares and smooth interphase ring is formed after HIPing.

显微组织研究表明，TiAl/Mo及TiAl/W复合材料在铸态下界面层厚度不大，且大多在TiAl基体中形成和长大，靠近Mo纤维的界面为光滑的环状，靠近W纤维的界面为微观不连续界面，而双方的另一侧以锯齿状向TiAl基体延伸。

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。
