As to the problem that the top apron cradle of carbon fiber is of complicated structure and high requirement of elasticity plus difficult cleaning, to upgrade quality of yarn, an introduction is made to the flat top apron cradle RS-6939 regarding its features. Through spinning practice with 100% long fiber cotton J 7.3 tex, J 4.9 tex, 100% fine fiber cotton J 9.7 tex, 14.5 tex, conclusion is made that the flat top apron cradle is of good abrasion resistance and rigidity, free of maintenance, stable quality, good anti-static property, thus being propitious to further upgrading evenness of resultant yarn, reducing slubs and snicks plus cotton neps, especially in production with fine fiber cotton.

针对目前使用的碳纤弹性上销结构复杂，对弹簧要求较高、不易清洁的现状，为了提高纱线品质，介绍了RS-6939型直板上梢的特点，并通过纺J7.3tex（100%长绒棉）、J 4.9tex（100%长绒棉）、J9.7tex（100%细绒棉）、J 4.5tex（100%细绒棉）的纺纱实践，指出RS-6939型直板上销具有较强的耐磨性和刚性，不需维修，质量稳定，杭静电性能良好，对进一步提高条干水平，减少粗节、细节及棉结非常有利，特别是在纺细号长绒棉时，效果更加显著。

He extinguished the candle by a sharp expiration of breath upon its flame, drew two spoonseat deal chairs to the hearthstone, one for Stephen with its back to the area window, the other for himself when necessary, knelt on one knee, composed in the grate a pyre of crosslaid resintipped sticks and various coloured papers and irregular polygons of best Abram coal at twentyone shillings a ton from the yard of Messrs Flower and M'Donald of 14 D'Olier street, kindled it at three projecting points of paper with one ignited lucifer match, thereby releasing the potential energy contained in the fuel by allowing its carbon and hydrogen elements to enter into free union with the oxygen of the air.

38他猛地朝火苗吹去，把蜡烛熄灭。将两把匙形木椅拖到炉边，一把是给斯蒂芬准备的，椅背朝着面临院子的窗户，一把是自己坐的。他单膝着地，往炉格子里放了些粘着树脂的枝条和五颜六色的纸张，以及从坐落于多利埃街十四号的弗罗尔与麦唐纳公司的堆置场以每吨二十一先令的代价买来的优质阿布拉莫木炭。他把这些都十字交叉地堆成不规则的多角形，划了一根安全火柴，在纸张的三个角落点上火。这样，燃料里的碳和氢这两种元素就与空气中的氧气自由化合，散发出潜在的能量。

Pearson＇s Correlation Analysis showed negative correlation between meiofauna abundance and phytoplankton biomass in term of carbon and nitrogen (-0.969 and -0.947, P.05). The total of 14 meiofauna groups were identified.

按生物量，海洋线虫(35.9％)、介形类(32.6％)、多毛类(13.7％)和桡足类(8.3％)共同构成小型动物的优势类群，80％以上的小型生物分布在0—2cn以浅表层内。

Nine wethers selected from a group at 2-years-old of age were fed with fresh mixtures of Leymus chinensis (30%), Cleistogenes squarrosa (20%) and Artemisia frigida (50%) in known proportions and amounts for 14 days. Artificial QSM capsules were dosed during the experiment. The samples of herbage and feces were collected daily for 7 days and dried for analysing the n-alkane concentration by a gas chromatography. The results showed that there was a difference in concentration of n-alkanes among 3 species forages, and fecal recoveries of n-alkanes linear increased with increasing carbon chain lengths.

于2004年秋季在中国科学院内蒙古草原生态系统定位研究站用不同放牧演替阶段的优势植物羊草、糙隐子草和冷蒿按一定比例混合组成日粮，饲喂9只2岁羯羊，每只羊投喂一粒QSM胶囊，试验期内每天记录绵羊实际牧草采食量、采食成分和排粪量，利用气相色谱分析牧草和粪样的链烷含量，应用链烷技术测定绵羊的排粪量、不同牧草采食比例和总干物质采食量，并与实际值进行比较。

The coordinated COD of 3 and 4 can be replaced by carbon monoxide to yield the corresponding dicarbonyl species [(C,N-pyN^C-R) M2]BF4 (14, M= Rh; 15, M= Ir). Ligand substitution of 11a by phosphines and azide causes the de-complexation of pyridinyl-nitrogen donor to generate the corresponding carbene rhodium complexes [(C-pyN^C-Mes)RhPR3] (17a, R = Ph, 17b, R = Et) and [RhN3] (19), respectively, indicating the labile nature of steric-hindered pyridinyl-nitrogen donor.

螯合错合物的吡啶配位，可以容易被σ-予体，如卤离子、叠氮阴离子、膦试剂，置换；但是铑与铱金属螫合物与π-酸试剂，如一氧化碳、异腈，则发生COD被置的产物14a与16；与三甲基亚磷酸酯反应时，COD及吡啶均会被取代而得到单芽的三铑-碳烯错合物18；双膦化合物则会取代铑金属上全部的配位基。

Company's annual production capacity of non-carbon copy paper 150,000 tons, ranking first in the country. 2008's production of Carbonless Paper 8.3 million tons, sales income of 6.5 billion, profits and taxes 67.14 million yuan and exports worth 19.09 million U.S.

公司无碳复写纸年生产能力15万吨，居全国第一位。2008年公司无碳复写纸产量达8.3万吨，实现销售收入6.5亿元，利税6714万元，出口创汇1909万美元。
