观察自然频率对振动模态的影响（固定阻尼系数），可对有强迫振动项 的情形进行观察，将阻尼系数和自然频率固定，选择一种 的形式，观察 对振动模态的影响。 2、对由方程刻画的单自由度阻尼系统做动画仿真，观察阻尼系数，固有频率以及强迫振动项 对弹簧振动的影响，并和振动曲线图进行对比，写出你的观察结论。 -1、To observe the natural frequency of the vibration mode of (fixed damping coefficient), may have forced vibration of items to observe the situation, the damping coefficient and natural frequency is fixed, choose a form of observation of the impact of vibration mode. 2, characterized by the equation of a single degree of freedom to do animated simulation of damping system to observe the damping coefficient, natural frequency and vibration forced vibration of the impact of spring items, and to compare and vibration curve, write your observations conclusions.

自动洗手器与自动干手器系统设计（内含电路图，有参考价值）-Automatic hand-washing device Automatic Hand Dryer with system design (including schematics, have reference value)

This schematic and Gerber files of PCB that is used for GSM alarm system. This is industrial-grade system with many features like 1-wire (iButton) interface, additional interface for video camera (UART JPEG camera is used), SD card to store pictures from camera and send them by GSM to remote mobile phone. Can be used as a reference design for anyone who wants to make own GSM alarm system system based on SIM300C module from Simcom.-This is schematic and Gerber files of PCB that is used for GSM alarm system.
