The Dongping Bridge is a new arcuated built-up system bridges. Half through steel box tied arch and prestressed concrete continuous beam were connected directly, and then the bridge becomes the Cooperation System Bridge with vice-arch.

东平大桥是一种新型的拱梁组合桥，由中承式钢箱系杆拱与预应力混凝土连续梁直接连接形成协作体系，并保留施工过程中的拉杆形成副拱。

RESULTS: Eight affected subjects had subnormal visual acuity due to high myopia. The results of colour vision tests were consistent with red-green CVD in six of these affected subjects. Fundus examination showed degenerative myopic changes characterized with generalized chorioretinal atrophy.Abnormal cone and rod dark-adaptation and diminished cone response in ERG were found in two subjects. According to family pedigree, it has been suggested that red-green CVD has X-linked recessive inheritance.

结果：患者8位均因高度近视视力下降，其中6例有红绿色觉缺失，眼底检查显示以弥漫性视网膜脉络膜萎缩为特征的近视改变。2例患者ERG检查出现视杆细胞的暗适应异常和视锥细胞的反应消失，根据家系，红绿色觉缺失属X连锁的隐性遗传。

The traditional way to manufacture the gashes of gear hob cutter is to mill it one by one, but the efficiency is quite low. With the proposed manufacturing process, the gashes could be generated by another specially designed hob cutter so that the manufacturing efficiency could be improved 2~3 times.

滚齿刀容屑槽之传统加工方式，系利用成型铣刀逐槽加工而成，除加工时程冗长外，铣制ZK 型蜗杆之缺点亦无法避免，本文再次利用滚制方式形成容屑槽，并解决传统制程上述之缺失。

The Huakou extra long bridge is a Lp=42 m tie bar arch bridge overcross the Xi an Lintong express highway.

豁口特大桥 Lp=42 m 系杆拱桥位于西安-安康铁路跨西安-临潼高速公路处。

On all accounts, beams and arches bear loads together in papilionaceous partial tied arch footbridge which can realize the equilibrium of strength and beauty.

在蝶式部分系杆拱步行桥中，主梁和拱圈充分发挥共同承重作用，达到力与美的平衡。

Based on the finite element method, a fresh and unique type of footbridge, a papilionaceous partial tied arch footbridge, was analyzed. The influences to the whole structure's stress behavior, displacements, vibration periods and mode shapes under parabola and arc arch axis were discussed. Different selections of support forms, such as longitudinal slide or longitudinal hinge, led to different behaviors on structure.

针对一种新型而特殊的蝶式部分系杆拱步行桥，基于有限元数值分析比较抛物线形拱轴线和圆弧形拱轴线对整个结构受力、变形、周期和振型的影响，揭示选用纵向滑动支座与纵向不动铰支座时给结构性能带来的不同结果，对结构拉索张拉力的控制给出建议。

Based on the construction of Danxi Bridge in Yiwu,this paper introduces the construction technology for installing main arch ring and sideling arch ring of leaned tied arch bridge.

以义乌丹溪大桥为背景，全面介绍了国内首座斜靠式系杆拱桥主、斜拱圈安装施工技术。

Under the background of Nanhe bridge on expressway of Nanjing to Hangzhou, this paper researches about monitoring mechnology of long-span concrete-filled streel pipe arch bridge.

以南京至杭州高速公路南河特大桥的施工为工程背景，对大跨径钢管混凝土系杆拱桥施工监控的关键技术进行了研究。

It is found that zero-displacement mothod can not be used in concrete-filled streel pipe arch bridge. When bend rigidness of tie-bar and bend rigidness of arch is almost same, rigid-support continuous beam mothod and the least-energy mothod without restriction formula is satisfactory.

对于吊杆初始张拉力的确定，将零位移法、刚性支承连续梁法和最小能量法用于南河特大桥吊杆初始张拉力研究，发现零位移法不宜用来确定刚性系杆刚性拱结构的吊杆张拉力，因为该法求解的索力不合理。

On the basis of the modification theory, relative modification concept of cycloidal gear pair and the appraisal index of the initial backlash are built to solve the problem that cycloidal gear works unsmoothly in pin wheel of the full-hydrostatic steering control units. The major goal of modification is a uniformity of initial backlash, so equidistance modification that has good effect on improving quality of fluid cycloidal pair is chosen.

为解决全液压转向器转子转动不灵活的问题，在分析现有摆线针轮啮合副齿廓修形理论基础上，建立摆线副修形的相对性概念和间隙分布评价指标，提出无系杆摆线副修形的主要目标应使初始间隙分布均匀，选择的修形方式为等距修形。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
