This program primely adopt the tactics that weaken the action strength of opponent.four corners priority tactics、the most edacity tactics.at the beginning of the game and the middle of the game,the program adopt weaken the action strength of opponent,namely reduce the positionn of the opponent to play the chess mostly;at the end of the game we use the he most edacity tactics,namely to eat up the chess of the opponent to the best of one ' s abilities;the four corners priority tactics is run through the whole game,the four corners of the chessboard are stabilization corner,can ' t eated up by the opponent,so here is the most important position of player to contest,at the same time of prevent opponent to put the chess in the corners of the chessboard,we make great efforts to put the chess in the corners.

本文首先详细介绍了黑白棋的游戏规则，和一些基本的战术，然后将这些战术编写成代码存储在计算机中，使计算机在对弈过程中，可以灵活的运用这些战术。该程序主要运用的战术有削弱对手行动力战术、四角优先战术、最大贪吃战术。在游戏开局和中局时，程序采用削弱对手行动力战术，即尽量减少对手能够落子的位置；在游戏终局时则采用最大贪吃战术，即尽可能多的吃掉对手的棋子；而四角优先战术则是贯穿游戏的始终，棋盘的四角为稳定角，不会被对手吃掉，所以这里是兵家的必争之地，在阻止对手进角的同时，自己却又要努力的进角。

The improved e-N method can also yield results well agree with those obtained by DNS.4 The transition prediction for boundary layers on cones with different key parameters such as angle of attack, cone half angle and the Mach number of the coming flow, have been made, to show the reliability of the modified e-N method.5 For the calculation of base flow, boundary layer equations can be used in the case of small angle of attack.

但是它要依赖于对初始扰动的正确预估，这显然又取决于更多飞行数据的积累和分析。e-N方法的转捩预测结果与直接数值模拟得到的结果也吻合较好。4通过对不同来流攻角、不同半锥角和不同马赫数的三维圆锥边界层的转捩位置进行预测，证实了改进的e-N方法对于三维边界层转捩预测是可靠的。5对于基本流的计算，边界层方程可以用于小攻角的情况，其计算量远远小于直接数值模拟，但背风面的剖面不可靠。

E. its equivalent investment value increases in the case of the unchangeableness of its real investment asset. So, the diversified operating can raise its profit rate.
