补充资料:速度环量
      表征流场涡旋强度的量,记为Γ,定义为速度矢量v沿封闭曲线L的线积分, 即,为曲线L的弧元素矢量,规定逆时针方向为L的正方向。速度环量同物体在流体中运动时所受的举力有密切的联系。
  
  涡通量和速度环量都能表征涡旋强度。由于速度环量的表达式比涡通量简单,所以在某些情况下,利用速度环量常比较方便。除此之外,在多连通区域的某些情形中,只能利用速度环量的概念来察觉并反映区域外"隐藏"着的涡旋。若流体是理想、正压的(见正压流体),且外力有势,则速度环量在随体运动过程中将不随时间改变(见开尔文定理)。由此可以断言,流体的粘性、斜压性以及无势外力将使速度环量随时间的推移有数值上的增减。
