中国中小企业互联网应用状况调杳报告: 近几年，中国互联网应用市场一直保持着快速发展，在国民经济中的地位不断提升。一 方面，个人的互联网应用市场不断发展，截至2010年末中国网民规模已达4.57亿；另一方 面，企业的互联网应用市场也逐渐步入成熟，继企业内部信息化之后，互联网成为企业发展 的又一强劲推力，互联网已经被广泛应用于企业的营销销售、客户服务、办事办公等方面。(The Chinese small and medium-sized enterprise Internet application status of the report were: In recent years, China s Internet application market has been maintained a rapid development of the national economy of stature. a , personal Internet application market development, at the end of 2010 the scale of China s netizens has reached 457 million The other party Surface, enterprise Internet application market also gradually into mature, the enterprise internal information after, the Internet becomes the development of the enterprise And a strong thrust, the Internet has been widely used in enterprise)

电子称重的实现首先是通过压力传感器采集到被测物体的重量并将其转换成电压信号。输出电压信号通常很小，需要通过前级信号处理电路进行准确的线性放大。放大后的模拟电压信号经AD转换进入主控单片机中，再将结果显示在人机界面。(The realization of electronic weighing is firstly to collect the weight of the measured object through a pressure sensor and convert it into a voltage signal. The output voltage signal is usually very small, which requires accurate linear amplification through the front signal processing circuit. The amplified analog voltage signal is converted into the main MCU by AD, and the results are displayed in the man-machine interface.)

已调试过，好用，但是速度可能不是很快。适合于实验教学用。若不能使用或者正确运行，请勿责怪，因为此程序是我随便传的

一个交通灯程序还有一个protel的仿真文件。(A traffic light program a protel simulation files.)

凸包 凸包问题的实现 有无数点，求能包含这些点的图形的最小面积(Convex hull Convex hull problem of realization there are numerous points, seek to include these points, the graphics, the minimum size)

UG内核文件pdf说明,x_t格式3D文件参考。(Introduction to the Parasolid API)

基于微信大转盘开发的，MVC模式，前台Jquery技术

该程序是单片机控制的数字时钟，总共有三个按键，第一个选择分钟或小时，第二个加一，第三个减一，该程序通过循环点亮数码管来显示时间，共用到8个数码管，硬件比较简单。
