A study was performed of the randomness of external loads on high arch dams,including flood,earthquake,landslide of mountains,etc.,the weakening of concrete strength of arch dams and rock strength of dam foundation,and the fuzziness of evaluation criterion.The disadvantages of conventional deterministic assessment methods for the safety of arch dams based on the strength theory and stability theory were analyzed respectively.It is suggested that fuzzy mathematics theory should be introduced to safety evalua...

研究高拱坝洪水、地震、山体滑坡等外载荷，坝身混凝土、坝基岩石材料强度弱化等的随机性，以及评价准则的模糊性；分析了高拱坝分别基于强度理论和稳定理论确定性评价方法的不足，提出应该利用模糊数学方法解决具有随机性、模糊性的高拱坝安全评价问题；建立了基于结构可靠度理论的高拱坝失效概率故障树模型并给出了具体算例。

See revised figure will increase based on SC-02 schematic form filling is not aimed at a base, is here to meet the requirements of the two programs are filling in the rubble masonry walls directly on the basis of the provisions under the Chinese drawing specifications, structure Orthography of commonly used map drawing, there is no column in the upper part of the case can not indicate a position of the axis of the concrete beam elevation, sections and steel can be combined with SC-07 and SC-08

中国国家建筑标准设计图集《03G101-1》第4.2.3条第六项有说明：梁顶面标高高差，系指相对于结构层楼面标高的高差值，对于位于结构夹层的梁，则指相对于结构夹层楼面标高的高差。有高差时，需将其写入括号内，无高差时不注。中国规范现在均采用的是平法施工图的简化表示方法，不需表示梁的剖面

Then the rats were still feed with high-fat, high-protein, and high-sugar food. After eight weeks, the rats in each group were given man-made deep second-degree burn.③The wound area was measured in 1, 3, 7, 14, and 21 days after burn to calculate the rate of wound healing.

实验过程：除烫伤对照组外，其他组大鼠通过高脂、高蛋白、高糖饲养后腹腔注射链尿佐菌素，建立老龄Ⅱ型糖尿病动物模型，并以高脂、高蛋白、高糖饲养。8周后各组给予深Ⅱ度烫伤。
