The results of prediction agree well with the experimental ones. It proves that the thermo-mechanical analysis、the neural network models of flow stress and microstructure as well as the numerical simulation system developed combining coupled thermal-mechanical rigid-viscoplastic FEM with BP neural networks are reliable to describe the hot back extrusion process of Ti15-3 alloy truly. The simulation system has good prediction capacity for the microstructure evolution of Ti-15-3 alloy during hot backward extrusion and after solution treatment. It can be used to replace the experiments for predicting the flowing laws and the distribution of microstructure.

The Zn-Ti distances are 0.369 nm and 0.335 nm for the single-corner adsorption mode and double-corner adsorption mode, respectively. Therefore, the EXAFS fitting data, R1=0.371 nm, R2=0.332 nm, can be well distinguished for SC and DC mode respectively. The calculation results also showed that the optimized Zn-O average distance of Zn-O tetrahedron is about 0.200 nm, which agree with the EXAFS results.

This study was conducted to examiune the fibrotic effect of Ni-Ti and 317L al loys in esophagus.The extract fluid from Ni-Ti,317L alloys was made according t o the ASTM standards of U.S.A. The Fb of esophageal scar was cultured primarily ,then incubated with alloy abstract fluid. The proliferating activity of Fb was measured by MTT at 4, 24, 48, 72 hours in the course of culturing. The esophagu s embedding test of Ni-Ti,317L alloys was made according to ASTM standards of U .S.A.The tissue around the alloys was taken at weeks 2 and 12,and the pathologi c changes were analysed.

The results showed that the combination of rare earth element La and transition element Ti is advantageous to the bonding state between diamond particles and matrix. So it can improve the materials properties.

经X射线衍射分析发现，合金粉中的活性La、Ce能够还原Ti颗粒表面的氧化物薄膜，提高了Ti的活性，从而促进了Ti和金刚石的反应。

On the other hand, if Ti foil is too thick, the interfacial reaction between liquid Cu-Ti alloy and Al〓O〓 ceramic can proceed sufficiently, due to the widening of the liquid phase region. This results in a too thick reaction layer, which also reduces the joint strength. Further more, in this situation, not all of the liquid alloy is isothermally solidified, similar to the case of brazing, the heatresistant of joint can't be improved.

相反，Ti箔过厚，一方面由于液相区宽度增大，连接过程中始终为Cu-Ti液体合金与陶瓷反应，导致形成过厚的反应层，降低接头强度；另一方而，由于连接后液相区未能完全等温凝固，与活性钎焊相类似，接头耐热性也难以得到提高。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
