This study involved field interviews of working postures of certain jobs in construction industry including labor for constructing retaining wall, carpenters, iron workers, concrete pouring, and electricians . Hazards of their working postures during operation were analyzed and compared using OWAS (Ovako Working Posture Analyzing System) postural analysis.

本研究系针对营建业部份之建筑工种，包含挡土柱、模板、钢筋、混凝土、水电等五种工种，进行工作姿势实地访谈；并透过 OWAS (Ovako working Posture Analysing System)工作姿势分析法，分析比对其作业工作姿势之危害程度。

As known from Leading Group Office of Human Recourse, Aba Autonomy will offer training courses to 3500 migrant workers who have been or plan to engage in business of construction work such as masonries, scaffolders, and carpenters, which are urgently needed.

记者近日从阿坝州人才工作领导小组办公室获悉。2月底前，阿坝州将免费培训3500名拟从事或已从事灾毁房屋重建工程的砌筑、混凝土、钢筋、架子工、木工等急需建筑业农民工。

Cities also create distinct microclimates. Bricks, concrete, asphalt, and other building materials absorb and hold heat, and buildings block wind flow. Motor vehicles and the climate control systems of buildings release large quantities of heat and pollutants. As a result, cities tend to have more haze and smog, higher temperatures, and lower wind speeds than the surrounding countryside.

城市也引起有区别的小气候，砖、混凝土、柏油和其它建筑物质吸收和保有热，还有街区风的流动，机动车和建筑物控制气候系统释放大量热和污染物，结果，城市有更多霾和烟雾，更高的气温和更低风的速度比起乡间环境。

城市也会产生明显的小气候，砖、混凝土、柏油以及其他建筑材料吸收以及维持温度还有阻挡对风的流动力，而马达工具和温度控制系统会释放出大的温度能量和污染物，因此，程式与周围农村比较有较多的薄雾与烟雾、高温度和较低的风速。

In the static test on Yi'an Bridge in Chongyi,we take a detailed examination and analysis about the flexivity、reinforcement stress、concete stress、steel wires stress of the steel-reinforced concrete、the low prestressing concrete and the full prestressing concrete on the twenty-meter long beam.

在崇义义安桥的静载试验中，对20 米标准跨径的普通钢筋混凝土、低预应力混凝土、全预应力混凝土空心板梁在均布荷载作用下的控制截面的挠度，钢筋、混凝土、钢绞线的应力作了较详细的试验、分析。
