摘　　要：将在动量空间具有积分形式的单胶子交换梯形近似下Ｂｅｔｈｅ－Ｓａｌｐｅｔｅｒ方程化为微分方程，求出该方程在四动量为零时的赝标解全部分量，其中第一分量为已知的Ｇｏｌｄｓｔｅｉｎ解．The integral Bethe-Salpeter equation in the approximation of single gluon exchange in momentum position is converted to a differential equation, and all the components of the pseudo-scalar solution of the equation for a vanishing total fourmomentum,including the Goldstein solution as the first component, are derived.
