钢筋

Pitting corrosion is one of the main manners of corrosion in reinforcement concrete.

坑蚀是混凝土钢筋锈蚀的主要形式之一。

The R/C frame structures were modeled with bar system and the column was modeled with multi-springs. The concrete and steel bars in column were considered as springs in order to reflect the coupling influence between the axial force and the moment-rotation relationship, the hysteresis of springs is based on the material properties and the rotation of column section is followed the plane assumption. The moment-rotation of beam section was modeled with trilinear hysteresis model.

混凝土框架分析模型采用杆系模型，其中柱采用多弹簧模型，柱端的混凝土和钢筋作为弹簧考虑以便反映柱轴力与弯矩－曲率的耦合关系，弹簧的滞回关系根据材料特性确定，柱截面的转动符合平截面假定，梁截面弯矩－转角关系采用三折线滞回关系模型。

The tension Poisson ratio is negative,and its regression curve shows upward section and downward section.

这可能与钢筋混凝土的泊松系数和弹性模量的取值有关。

It was written by Peter S. Du Ponceau, president of the American Philosophical Society of Philadelphia, and also includes A Vocabulary of the Cochin-Chinese Language by Father Joseph Morrone, R.C. Missionary at Saigon, and A Cochin-Chinese and Latin Dictionary. 374 pages.

它的作者是醒都丽春，美国哲学学会会长，费城，也包括对交趾词汇由约瑟夫神父莫罗内，钢筋混凝土中语言传教士在西贡，和A科钦，中国和拉丁美洲的字典。

Tests reveal that the bottom of the reinforcement cage corresponds to the minimum of the electric potential gradient curve and the inflexion of the electric potential curve.

结果表明钢筋笼的底端对应于电位梯度曲线的极小值点及电位曲线的拐点。

Fick's second law was always used to describe the diffusion properties of chloride in the concrete. For the application of Fick's second law in the prediction of the service life of reinforced concrete structures, many researchers have already made studies on this issue.

Fick第二定律通常被用来描述氯离子在混凝土中的扩散性质，对於Fick第二定律在钢筋混凝土结构寿命预测的应用，已经有许多学者对其进行了研究。

The developed program also has some post-processing functions including structure shape map, discrete structure mesh map, structure displacement map, cracking map, stress map of steel bar, principal stress map of any section, searching displacement of any load step, load-deflection curve map of any node and so on.

包括结构形式图、结构剖分网格图、结构变形图、裂缝开展图、钢筋应力图、任意横截面的主应力图、加载过程中的任意荷载下的位移查询、任意结点的荷载—挠度曲线图等。

Based on principle of conservation of energy, the thermal field of concrete component can be gotten by the method of finite element.

通过化学与物理分析，可以了解火灾的高温作用对钢筋混凝土材料性能的影响，结合试验研究，能够从宏观和微观两个层面得到灾后混凝土材料性能的变化规律。

When you follow your r...

当你走你的钢筋。。

Now it houses a vast, futuristic steel and concrete structure, China's first Formula One racetrack.

现在，一座巨大的、极其先进的钢筋水泥建筑物－－中国首条一级方程式赛车道已经座落在了那里。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
