在事件驱动机制中,由用户激发的某个事件去执行相 应的事件过程。这些事件处理过程之间并无特定的执行顺 序,但每个事件过程内部却包含着三种结构。在顺序结构 中,语句将按照出现的顺序逐条执行

In the previous lectures we have described particle motion as it would be seen by an observer standing still at a fixed origin. This type of motion is called absolute motion. In many situations of practical interest, we find ourselves forced to describe the motion of bodies while we are simultaneously moving with respect to a more basic reference. There are many examples were such situations occur. The absolute motion of a passenger inside an aircraft is best

一,基本概念(Basic Concepts):在本章,我们只限于研究平面弯曲梁的变形和位移。在平面弯曲条件下,梁的直轴线受载变形后,成为载荷作用平面内的一条平面曲线----挠度曲线(挠曲线 Deflection Curve),它又叫弹性曲线(Elastic Curve)
