In this paper, the development of multifunctional composite fiber materials for silk products is studied. By means of various combinations of mulberry silk with such textile materials as silk floss yarn, silk wool yarn, linen, viscose, soybean fiber and silk elastic fiber, which are fit for small-batch production, six major categories of high-quality composite silk materials (burn-out, soybean, silk floss, elastics, silk linen, and silk wool) are developed, covering more than one hundred types.

The assembly method of the invention has the main principles that a semiconductor laser, an optical coupled apparatus and a fiber head are orderly arranged, and the optical axes of the semiconductor laser, the optical coupled apparatus and the fiber head are arranged in a same straight line; the focal plane of an output beam which is focused on the fiber head is changed through utilizing and adjusting an adjusting device which can cause a beam to deviate; the sensitivity of the assembly adjustment of the adjusting device in the course of fixing is reduced.

本发明的方法的主要原理是将半导体激光器、光学耦合器件、光纤头依次排列，并使它们光轴在同一直线上，然后通过利用一使光束发生偏移的调节器件，通过调节该调节改变聚焦于光纤头的输出光束的焦平面，降低调节器件装配调节的固定时的敏感性。

When a capillary tube, in whose inner hole an optical fiber has been fixed and whose axial deviation amount between an outer peripheral surface of the capillary tube and a core center of an end surface of the optical fiber is 1.5 mum or less, is inserted into the insertion portion of the thin tube and the end surface of the optical fiber is fixed at a position at which a distance of the end surface to a focal point position of the partially spherical lens becomes -40 mum or less, emission light has an emission light bend of 0.2 DEG or less with respect to the center axis of the thin tube.

当将光纤固定在内孔且外周面与光纤的端面的纤芯中心的轴偏移量在1.5μm以内的毛细管插入细管的插入部，并且将光纤的端面固定于部分球面透镜的焦点位置±40μm以内的距离的位置上时，出射光曲率为出射光相对细管中心轴在0.2°以内。

In recent years, there is wide attention on fiber grating and its application in fiber sensors and fiber communications.

近年来，光纤光栅及其在光纤传感器和光纤通信领域中的应用研究引起了人们普遍的关注。

For protecting the signal transmitting fiber in downhole high temperature and pressure environment, an epoxy-free package method based on hermetical bonding of quartz ferrule and fiber is used and Polyimide coated fiber and stainless steel protecting tubing are adopted.

我们采用金属—石英管的机械压力密封和石英管—光纤的激光热熔无胶密封结构，保证了传感器导压腔和耐高温光纤不锈钢保护套管的可靠密封，提高了整个系统的可靠性和使用寿命；采用不锈钢套管保护聚酰亚胺材料涂敷的耐高温光纤传输传感信号，解决了耐高温和保护光纤的问题。

The production process needs only 3 hours , but the yield of Tencel fiber raises about six times compared with that of common rayon. The NMMO solvent is completely innocuousness to human bodyand can be completely recovered (about 99.5%) and reused. So the production process is green process. Tencel fiber is credited green fiber in the twenty-first centuries.

相比普通粘胶纤维，整个生产过程仅需约3小时，然而Tencel纤维产量可提高6倍左右；Tencel生产中所使用的氧化胺溶剂对人体完全无害，并可完全回收(99.5%以上)和反复使用，生产中原料浆粕所含的纤维素分子不起化学变化，无废弃物排出厂外，不会污染环境，属于"绿色生产工艺"，所以Tencel纤维被誉为二十一世纪绿色纤维。

This thesis is concentrated to study the fiber flexibility of kenaf core CMP and wheat straw chemical pulp and the factors affect the fiber flexibility and the ways to increase the fiber flexibility.

本文主要研究了麦草化学浆和红麻杆化机浆的纤维柔软度，影响纤维柔软度的因素以及提高纤维柔软度的措施，最后探索了纸页抗张断裂机理及其与纤维特性的关系

The now available long-range supervision system at home and abroad is based on the optical fiber mostly, and if the optical fiber runs into that the machinery lashes and colliding optical fiber may split or break. Once splitted, it's hard to be restored because of the sophisticated equipment, and ordinary user can't restore it by means of the welding at all. Moreover the high price of light transmitter and light receiver limits the application and popularization.

国内外现有的远程监控系统大多基于光纤，而光纤如果遇到机械冲击、碰撞等都会造成光缆断缆或断芯，光缆断裂后，很难快速修复，且修复设备复杂，普通用户根本无法进行焊接修复，再加上光端机价格较高，这些都限制了光纤远程监控系统的应用和普及。

In this paper, the performance characteristics of bamboo carbon viscose fiber are described, and the processing practice in spinning blended knitting yarn of bamboo carbon viscose fiber and combed long-staple cotton fiber is discussed with its process flow and key measures in each process proposed.

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.
