The cold-formed sheet is a groove-shaped structure that is composed of a crown plate and reinforced ribs connected with ends of the crown plate; the box beam is a box-shaped structure comprising an upper wing edge, a lower wing edge and two side webs that are connected in every two components.

由压型钢板、纤维增强塑料箱梁组成，压型钢板为由顶板和顶板端部的加强肋相连组成的槽形结构，箱梁为由上翼缘、下翼缘和两侧腹板两两相连组成的箱形结构，其结构如图所示。

The blunting process of the high speed steel cutter blade in the course of fiber cutting can be divided into two stages: the rapid blunting at the 1〓 cutting stage and finally the gradual blunting stage before failure.

切断刀的钝化过程取决于其失效机理，硬质合金材料强度低，在纤维施加的应力作用下，切割初期切断刀刃口产生局部断裂，形成尺寸较小的锯齿形缺口，造成锋利度快速下降。

Methods The experimental mice were given 200 g/L sweetpotato anthocyanin with a dose of 36 mL/kg, three times a day, for 14 days. Body weight and death rate were recorded. The mutagenicity of sparfloxacin on CHL cell in the presence and absence of S9mix was evaluated.

采用最大给药量试验，小鼠每天3次、每次36 mL/kg灌胃给予200 g/L的青紫薯色素水溶液14 d，观察其体质量变化和死亡情况；以仓鼠肺成纤维细胞行染色体畸变试验，对青紫薯色素进行毒理学评价。

From the investigation into the visible spectra and performances on textile of these azo dyes, as acid dye, it was found that these dyes had deep coloring effects on dyeing wool or silk, and five of which could dye wool into black one at 3% o. w. f., especially the diazo dye derived from 2, 8-diamino-10-methoxy-5, 10-dihydrophenophosphazine 10-oxide and acet-J-acid, it could not only dye wool into black one but each fastness of the obtained dyed sample was good.

对这些已知结构的染料进行浸染染色，结果发现，它们作为酸性染料，在羊毛及丝绸纤维上染色时，能够获得比一般偶氮染料不宜获得的深色效应，其中5支染料得到黑色染样，尤其由2，8-二氨基-10-甲氧基-5，10-二氢磷杂吖嗪与乙酰J-酸形成的双偶氮染料得到黑色染样，其各项牢度都比较理想。

To dye the different types of fibers by the same dye, universal dyes based on naphthalene ring system are prepared by the diazo coupling reaction of 7-acetamide-4-hydroxy-2-oaphtialene-β-(N,N-dimethylaminoethyl)solfonamide and m-aminobenzene-β-hydroxyethyl sulfone sulfunate.

为了实现用同一支染料对不同类型的纤维进行染色的目的，通过间氨基苯基－β-羟乙基砜硫酸酯与7-乙酰氨基－4-羟基－2-萘－β磺酰胺的重氮化偶合反应合成了含萘环的通用染料，其结构通过质谱分析进行了表征。

Formulation of special anti-decrepitude, dissolve the cell particle,and make already the decrepitude's cell slowly recovers the ability of its abruptions, and repair the decrepitude the fission's flexibility fiber.

独特的抗衰退老配方，祛除细胞微浆粒，使已衰老的细胞慢慢慢慢恢复其分裂能力，修复衰老断裂的弹性纤维。

The decrease of GAG content in the degenerated annuli fibrosus is mainly caused by the decrease of CS.

退变纤维环GAG含量下降由其主要成分CS含量下降所致。

Results show that when exposed to the severe environment of salt lakes, both OPC and APC display poor durability, though HSC shows excellent bittern-freezing-thawing durability, the corrosion resistance against bitterns is not so good, while non-air-entraining HPC shows outstanding performance in both bittern-freezing-thawing durability and corrosion resistance against bitterns, and the performance can be farther improved by adding fibers.

结果表明，在盐湖地区的严酷条件下，OPC和APC的耐久性不好，HSC具有优良的抗卤水冻蚀性，但是其抗卤水腐蚀性比较差，高强非引气HPC具有优异的抗卤水冻蚀性和抗卤水腐蚀性，纤维增强HPC的效果更佳。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
