Results: The hairy root was successfully induced and the hairy root culture system was set up; The opines assay was positive for mannopine and agropine; The result of determination showed that there were a lot of anthroquinone constituents in the rhubarb hairy root and the contents of rhein, aloe-emodin, emodin or 8-O-methylchrysophanol were respectively higher than those in wild plant root.

结果：诱导出了天山大黄发根，并建立了发根离体培养系；从发根中检测到甘露碱、农杆碱的存在；定量分析发现，天山大黄发根中含有多种蒽醌类成分，其中大黄酸、芦荟大黄素、大黄素、大黄酚-8-甲醚的含量分别高于原植物根中的含量。

The paper analyses the development and the present status of the ultimate bearing capacity of the tiede arch bridge.

本文调研并分析了系杆拱在国内外的发展及拱桥极限承载力的研究现状。

Bridges of similar construction, in a cross-bridge under 5 CFST tied arch bridge, is the first time.

类似桥梁的建设，在跨下5钢管混凝土桥梁系杆拱桥，是第一次。

The article uses the plane simplifying calculation method and the space finite element method to analyze the bearing characteristics of the arch rib when the concrete is poured into the steel pipe and the batten plate chamber of truss type steel pipe concrete tied arch bridge.

采用平面简化计算方法与空间有限元方法对桁架式钢管混凝土系杆拱桥灌注钢管及缀板腔内混凝土时拱肋的受力特性进行了分析。

Iron production was revolutionized in the early eighteenth century when coke was first used instead of charcoal for refining iron ore. Previously the poor quality of the iron had restricted its use in architecture to items such as chains and tie bars for supporting arches, vaults, and walls.

自从焦炭第一次被铁矿石中提炼出的木炭所取代时，铁产品早在18世纪就已经被彻底改革了，原来的质量差的铁已经在以下这些领域的有限的被使用，如铁链、支撑系杆、拱顶以及墙壁。

The 4th Qiantangjiang River Bridge in Hangzhou is a concrete-filled steel tubular composite tied arch bridge with double decks and double main arches.

钱江四桥为双层桥面双主拱钢管混凝土组合系杆拱桥，主桥共有11跨，包括了下承、中承、上承三种拱桥形式。

Only 1,000, 000 vehicle crossings produced significant cracking in the floor beams of the tied arch span and in the plate girders of the approach spans.

仅通过1，000，000辆车就在系杆拱的横梁中以及引桥的板梁中造成明显的开裂。

B lifting, the rope not tied hand wheel or valve stem.

b起吊时，绳子不要系在手轮或阀杆上。

Main conclusions of this paper are listed as bellows: First hinge line is not particular in the complete-system, but the close bar on it will generate great stress while the initial stress is imported. So the structural shape has not only great relations with the position set of the hinge line, but also maximum impacts on the deformation of the whole body. Equal to the support part of jacks, the circumference of the fist hinge line will generate the greatest impacts while exchange.

本文研究的主要结论有：第一铰线在完成系中没有特殊之处，但在初期应力导入时，第一铰线上的闭合杆件会产生相当大的应力，因此，结构形状和铰线的位置的设定有很大关系，对结构整体变形也有最大的影响；第一铰线的周边相当于千斤顶的支承部，在替换支撑拆除千斤顶时会产生很大的影响。

The split between the two groups can hardly be papered over.
