化学纤维

Among them, the rapid decline in industrial output value of industry of petroleum and natural gas industry, the waste of resources and waste material recycling processing industry, wood processing and wood, bamboo, rattan, palm, grass products, ferrous metal smelting and rolling processing industry, chemical fiber manufacturing, leather, fur, feathers and its products industry, gas production and supply industry, chemical materials and chemical products industry.

其中，工业总产值下降较快的行业有石油和天然气开采业，废弃资源和废旧材料回收加工业，木材加工及木、竹、藤、棕、草制品业，黑色金属冶炼及压延加工业，化学纤维制造业，皮革、毛皮、羽毛及其制品业，燃气生产和供应业，化学原料及化学制品制造业。

The dyes were extracted from textiles composed of natural or chemical fibers by methanol under ultrasounication, and then eluted with gradient by acetonitrile and 5 mmol/L ammonium acetate from an RP-C18 column with two segments in effluents. The first effluents accommodated Acid Red 26, Direct Blue 6, Direct Black 38 and Direct Red 28 with negative ionization mode, while the second accommodated Basic Red 9, Basic Violet 14, Disperse Blue 1, Disperse Orange 11 and Disperse Yellow 3 with positive ionization mode. Thus the investigated compounds could be identified simultaneously with single-run analysis no matter which type of the fibre the sample was and no matter which category of the dye the analyte was.

用甲醇超声同时提取天然纤维和化学纤维上的染料，以5 mmol/L乙酸铵和乙腈为流动相在C18柱上于前段洗脱酸性红26、直接蓝6、直接黑38和直接红28（采用电喷雾质谱负离子模式检测），于后段洗脱碱性红9、碱性紫14、分散蓝1、分散橙11和分散黄3（采用电喷雾质谱正离子模式检测），实现了对不同种类纤维织品中分属4类性质不同染料的一次提取和一次分析检测。

The preceding process of the machine is combinedopeningandscutchingmachine and thefollowing process is drawing frame.

本机的前道工序是开清棉联合机，后道工序是并条机，主要用于加工棉纤维和化学纤维。

The combined massaging and brushing tool of claim 1 wherein said convexes are of conical shape.

又名丝：在化学纤维制造过程中，纺丝液从纺嘴挤出，在纺丝箱中冷却或在凝固浴中凝固成形，成为连续不断的丝。

A combined massaging and brushing tool comprising a main body having a plurality of convexes neatly arranged on a surface thereof, a cutting line positioned suitably away from an end edge thereof and extending in both directions along said end edge wherein an opening is formed by removing said body along said cutting line, a plurality of cutting lines suitably spaced and disposed in the proximity of another end edge thereof and respectively extending downwardly from a location in the proximity of the center wherein a set of enclosures are formed by removing said body along said cutting lines.

一般而言，长纤维是指纤维之长度/厚度之比率大于10%者称之。而在化学纤维当中，所有可纺丝之原料，皆可制成长纤维。长纤维因其每束丝中各单纤维根数与细度又可分为复丝与单丝，通常用于衣着类长纤维大都为复丝，而单丝则大都在非衣着用途，如钓鱼线等，其单纤维直径为60μ以上，甚至可达5 mm。

In chemical fiber, polyester fibber function wastage of admirable, resource is inferior, competition ability is the strongest, acrylic fibbers take second place, acrylic fibbers, polypropylene fibber is mixed in function with fiber sticking gum half and half of bad of the actor on resource, paratactic the 3rd.

在化学纤维中，涤纶性能优良、资源消耗量较低，竞争力最强，腈纶次之，腈纶、丙纶和粘胶纤维在性能和资源上优劣各半，并列第三。

Natural fiber and chemical fiber have an advantage each on function and resource, competition ability comparatives.

天然纤维和化学纤维在性能和资源上各有优势，竞争力相当。

Used for determine specific resistance of various chemical fibres.

用于测定各种化学纤维的比电阻值。

Used for determine specific resistance of various chemical fibres.

产品介绍：用于测定各种化学纤维的比电阻值。

"Cellulose acetate is the second largest sort among cellulose fiber only next to gum fiber. Cellulose acetate's main raw materials main include wood pulp and cotton flannel that are all reproductive.

醋酸长丝在化学纤维中最酷似真丝，光泽柔和，手感柔软滑爽，不易受水浸湿，回潮率低，弹性好，不易起皱，具有良好的悬垂性与热塑性，染色鲜艳，是优良的纺织原料。

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.

交际能力和语法的关系应该是目标与途径的关系。
