采用残余应力和力学性能测定、化学成分分析、断口扫描及金相检验等方法对铁路货车用l - B型组合式制动梁撑杆翼板产生裂纹的原因进行了分析。
Many experimental results indicates, beam bar slippage within joints is a frequent local nonlinear response of reinforced concrete structures under the rare earthquakes.大量试验结果表明,在罕遇地震作用下节点核心区内梁纵筋的粘结滑移是钢筋混凝土结构的一种比较常见的局部非线性反应。
It is accurate to within 0.03mm. The same sensor is used on a boat to shine a beam off the tiller bar, using the reflection to measure the Angle of the rudder.这个感应器非常精确在0.03毫米内,同样的感应器也用在船只上去投射舵柄连接杆发出的电波,利用反射去计算舵的角度。
