The results show that the zirconium sol has good spinnability when n: n= 1:3, reaction time is 6h and aging temperature is 15℃. The ZrO_2precursor fibers are made from hydrous zirconia chelated by acetylacetone. The sintercd fibers arecomposed of metastable tetragonal phase and sized about 15μm in diameter. Moreover, there aremany pores inside the fibers, but no cracks.4. ZrO_2/PVP hybrid fibers were prepared by blending the spinnable zirconium sol and 10 wt%PVP solution.

Mechanization transit more and more extensive get application, have become in recent years develop the most quick profession one in mechanize transport field in, chain transport can realize vertical, level, incline , bend and make up mutually various transport locus, can again meet bulk, take pack wait for the stock of various types carry ; can satisfy operation steady, transport at low speed may control with metre automation production the late requirement of operating mode, again can in bad environment in reliable work, chain conveyer is performance good continuous conveyer, it need not stop in same one side to transportation stock, load and unload need not stop machine, have very high productivity.

摘要机械化运送越来越广泛的得到应用，近年来已成为发展最迅速的行业之一在机械化输送的领域里，链条输送既能实现垂直，水平，倾斜，弯曲及相互组合的各种输送轨迹，又能适应散装，带装等各种类型的物料搬运；既能满足运行平稳，低速输送和节拍可控的自动化生产先的工况要求，又能在恶劣的环境里可靠的工作，链条输送机作为性能良好的连续输送机，它可以不停的在同一方向运输物料，装卸无须停机，具有很高的生产率。

This paper also makes a experimental study of the regularities of the outstripping machining in aspects of machine tool, cutting tool, cutting conditions and so on, and points out that the outstripping phenomenon occurs on the following conditions: the machine tool with high precision, the PCD cutting tool with small clearance and lay angle, the small installation angle, the small feed rate and the cutting lubricant with good properties, and that the cutting speed and the depth of cut have no effects on the outstripping machining.

本文还从机床、刀具和切削条件等方面对超越性加工的规律进行了实验研究，指出超越性加工现象是在如下条件下产生的：较高精度的机床、后角和刃磨纹理角较小的PCD刀具、较小的安装角和较小的进给量以及冷却润滑性能良好的切削液，而切削速度和切削深度对超越性加工几乎没有影响。

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。
