PowerBuilder的一些实例，适合初学者学习使用(Learning source code)

小熊的日记，获取日记列表目前为本地缓存数据 + 本地假数据， TODO 从服务端拉取从server端拉取，使用生命周期函数--监听页面加载，TODO 并不是所有非中文字符宽度都为中文字符宽度一半，需特殊处理，由于文本框聚焦存在bug，故编辑模式待实现。 　　这个日记本程序，运行于微信小程序环境，支持日记聚合，加载Loading、tab项事件、预览模式、右上角工具栏、图片预览和多媒体预览模式等众多辅助功能，可从中学习到一些实用的微信小程序开发技巧。

说明：  关于车辆与桥梁的振动问题，主要是车辆动力系统与桥梁动力系统之间的耦合振动问题。车辆以一定的速度在桥上运行，会使桥体产生振动，同时车辆的振动也会使桥体产生振动。桥也会影响车辆的振动。这种相互影响、相互作用的问题，就是车辆与桥梁之间的耦合振动问题。我们用MATLAB写出根据Newmark-beta方法的代码来处理耦合方程。(The vibration of the vehicle and bridge is mainly the coupling vibration between the vehicle power system and the bridge dynamic system. The vehicle running on the bridge at a certain speed will make the bridge vibrate, and the vibration of the vehicle will also make the bridge vibrate. Bridges can also affect the vibration of vehicles. This interaction problem is the coupling vibration between vehicle and bridge. We use Matlab to write the code according to the Newmark beta method to deal with the coupling equation.)
