数独是一种源自18世纪末瑞士的数学智力拼图游戏。拼图是九宫格（即3格宽×3格高）的正方形状，每一格又细分为一个九宫格。在每一个小九宫格中，分别填上1至9的数字，让整个大九宫格每一列、每一行的数字都不重复。 数独的玩法逻辑简单，数字排列方式千变万化。不少教育者认为数独是锻炼脑筋的好方法。-Sudoku is a kind of Switzerland originated in late 18th century mathematical intelligence jigsaw puzzle. Puzzle is the squares (ie, 3 cells wide × 3 grid H) of square-shaped, each divided into a fine grid squares. Small squares in each of the respective fill in the figures 1-9, so that the whole big squares in each row, each row will not repeat the figures. The logic of playing Sudoku is simple, the arrangement of the ever-changing figures. Many educators think Sudoku is a good way to exercise their brains.

Delphi实现Excel数据导出到Access数据库中，见经常有新人问到如何将 Excel 数据导入数据库，我当年也花了一段时间去搞，就做了个简单的DEMO,希望对新手有用.

斯皮尔曼相关性，斯皮尔曼系数一般有两个公式，由排行差分集合d计算而得（公式一）由排行集合x、y计算而得（斯皮尔曼等级相关系数同时也被认为是经过排行的两个随机变量的皮尔逊相关系数，以下实际是计算x、y的皮尔逊相关系数）（公式二）(different types functions)
