暖通冷凝器计算的excel表格计算文档，比较实用(HVAC condenser calculation excel spreadsheet documents, more practical)

使用sph方法求解NS方程，在此程序中考虑了表面张力的影响(this code solves N-S equation which uses SPH method，further more it consist of the surface tension part。)

利用tglvm算法对两类结果实施迁移学习分类，分类正确率达90%以上；(Tglvm algorithm is applied to classify the two kinds of results, and the correct rate of classification is more than 90%;)

说明：  四步相移法得到相位图，再利用解包裹得到正确完整的图(Phase diagram obtained by four step phase shifting method)

文针对 INS/ GPS舰船用组合导航系统进行 研究,为提高 INS 误差的修正精度,采用高精度 GPS姿态测量系统为 INS提供外部修正信息,以增 强系统的观测量.在对自适应卡尔曼滤波器分析的 基础上,提出了一种新的基于新息估计的自适应卡 尔曼滤波算法,以解决外部量测噪声出现不确定强 度变化问题.(Text for the INS/GPS navigation system for ships to study, to improve the accuracy of INS error correction, using high-precision GPS attitude measurement system for the INS amended to provide external information to enhance the system of observations. In the adaptive Kalman filter Based on the analysis, a new interest rate is estimated based on the new adaptive Kalman filter algorithm to solve the external uncertainties, the measurement noise intensity change.)

VB 读取 excel 文件的操作。 可以读取2003 和2000的文件(VB to read excel file operations. You can read the 2003 and 2000 documents)

本程序进行了一个电动助力转向系统的PID控制仿真(This program carries out a PID control simulation of electric power steering system.)

上海大学陈伯时主编-电力拖动自动控制系统PPt课件。 (Shanghai University, Chen Boshi Editor- Power Electronics and Electric Systems PPt courseware.)

DirectX中，使用的纹理坐标系统有两个轴向，分别称为u轴，和v轴。u轴从左到右依次增长，v轴从上到下依次增长。纹理坐标(u,v)定义了在纹理图片上的一个像素点，称为纹素。(I hope it can help you the grid load code and program example is more animation)
