A novel feature recognition method based on part modeling process which was recorded by way of macro command in CAD systems was proposed herein: geometry and topology entities which produced by single modeling process were analyzed in the single feature recognition process and all features in part were recognized based on step by step strategy.

These tendons also can assume the moments at the end of the beams in ordinary condition. By way of these tendons, precast beams and columns can be assembled conveniently, and the joints and frame are monolithic and continuous. Consequently, compared with common reinforced concrete frames, this kind of frame systems possess higher reliability and solved the problems in the process of assembling Prestressed Concrete frames. Also it forms the framework of Prestressed Subassemblage concrete frame, and explores a new way for industrial production of prestressed structures.

By way of attempting to give the reader some general impression of the way people lived together in those days, and especially of the relations of the rich and poor to one another, perhaps I cannot do better than to compare society as it then was to a prodigious coach which the masses of humanity were harnessed to and dragged toilsomely along a very hilly and sandy road.

That loss of credibility has occurred. The job of CEOs is now to regain America's trust – and for the country's sake it's important that they do so.They will not succeed in this endeavor, however, by way of fatuous ads, meaningless policy statements, or structural changes of boards and committees. Instead, CEOs must embrace stewardship as a way of life and treat their owners as partners, not patsies. It's time for CEOs to walk the walk. Three suggestions for investors: First, beware of companies displaying weak accounting.

The effect of the tool composition on the friction and wear behavior was investigated,and the morphologies of the rake face and rear face of the tool cutting the steel in air and nitrogen were observed on a scanning electron microscope. It was found that the Al_2O_3/TiB_2 tool was dominated by adhesive and abrasive wear in low speed dry cutting; while in high speed dry cutting,the tool was characterized by oxidation wear. An oxide layer of TiO_2 was formed by way of the oxidation of the reinforcing agent TiB_2 at a very much high cutting temperature, which contributed to greatly reducing the friction coefficient and increasing the antiwear life of the tool.Such a friction-reducing and antiwear behavior of the oxide layer was enhanced with increasing content of TiB_2 in the tool composite. However,the tool showed a relatively poorer wear resistance in N_2 than in air, because N_2 acted to retard the oxidation of the TiB_2 and the formation of the oxide layer on the tool rake face.

In this thesis, the research about surface modification of titanium alloy was carried on starting with improving stability of calcium phosphate biomedical coating by force of chemical treatment, Physical Vapor Deposition of titanium metal at high temperature and Electrophoresis Codeposition and sintering technology of the coating. By way of the studying of graded design of microstructure and composition of coating and EPCD and sintering technology, a systemic technology by which a calcium phosphate graded ceramic coating was prepared and sintered rapidly on the surface of a complex shaped product was obtainedand a high function titanium alloy/bioglass/hydroxyapatitegraded coating wasdeveloped.
