The low-dimensional Galerkin method is generalized to solve the flow around arbi-trarily translating circular cylinder.Active control problems of wakes behind circularcylinders are numerically investigated by only small number of modes.The in-line andtransverse oscillation of a circular cylinder with proper frequency produce Karman vor-tex street successfully in some subcritical regime,vhereas the transverse oscillation of acircular cylinder with 1.8 times the natural shedding frequency can effectively suppressthe Karman vortex street at a slightly supercritical Re.

将低维Galerkin方法推广至可以求解任意平移运动圆柱的绕流问题，用较少的模数值研究了圆柱尾迹的主动控制问题，在亚临界Re数下圆柱以适当的频率沿流向和横向振动均成功地激发出Karman涡街；而在略高于临界Re数下圆柱以1.8倍自然脱涡频率沿横向振动明显地抑制了Karman涡街；再现了超临界Re数横向及流向振动圆柱绕流的频率锁定等复杂非线性现象。

Above all, in nowadays background, simply combine the classic learning method to pattern recognition for constructing a classifier is impolitic, because the ultimately purpose of recognition is to have a higher performance with higher predictive accuracy.

综上所述，在目前的研究背景下简单地用经典的归纳学习算法进行学习来构成模式识别用的分类器是不审慎的，因为构成具有高判决精度的分类器是模式识别的最终目的；而如果不加考虑地任意采用一种现成的决策森林算法或多变决策树算法来解决实际问题也不一定就能取得更理想的效果。

The Winklhofer method is an exact method.But Winklhofer method cannot calculate centerdistance of a roller chain drive whose length of chain is an odd number of chain pitches.Involute function method is anapproximative method.

W ink lhofer方法是准确的计算方法，但只能用于链条总长是链节的偶数倍时的链传动，而渐开线法是近似法，不能精确地计算链传动中心距；而二分法是一种数值法，它可精确地计算链传动中心距，并且适用于链条总长是任意值的链传动，可计算出链传动中心距最大值和最小值。

Brief and powerless is Man's life; on him and all his race the slow, sure doom falls pitiless and dark. Blind to good and evil, reckless of destruction, omnipotent matter rolls on its relentless way; for Man, condemned to-day to lose his dearest, to-morrow himself to pass through the gate of darkness, it remains only to cherish, ere yet the blow falls, the lofty thoughts that ennoble his little day; disdaining the coward terrors of the slave of Fate, to worship at the shrine that his own hands have built; undismayed by the empire of chance, to preserve a mind free from the wanton tyranny that rules his outward life; proudly defiant of the irresistible forces that tolerate, for a moment, his knowledge and his condemnation, to sustain alone, a weary but unyielding Atlas, the world that his own ideals have fashioned despite the trampling march of unconscious power.

人的生命是短暂而脆弱的，不可避免的死亡虽然缓慢，但一定会降临在每一个人身上，阴森而无情，这个全能的物质世界毫不容情地滚滚前行无视善恶，任意摧毁，对与人来说，注定今天要失去最亲爱的亲人朋友，明天自己也要通过黑暗的死亡之门，人的生命存在就在于死亡来袭之前，珍惜那些使他短暂的生命变得高贵的思想，鄙弃对命运的恐惧，对自建的圣坛顶礼膜拜，不受机缘的摆布，摆脱主宰他外部生活的粗暴统治而取得心灵的自由，敢于骄傲地向那些不可抗拒的压力挑战----这些压力对其认识和判断力不过是暂时的----他就像疲惫而不屈的擎天巨神，独自支撑着他自己的理想世界，对这种无意识力量的肆意践踏毫不理会。
