我们在10维pp波背景上构造了IIA GS超弦作用量，它是11维pp波几何沿等距方向的紧致。背景几何有24个杀伤性自旋，其中16个分量对应于弦作用中非线性实现的运动学超对称性。剩下的8个分量是线性实现的，并被证明与x^+坐标无关，x^+坐标与光锥标尺中弦动作的世界片时间坐标相一致。研究了得到的动力学N=(4，4)超对称性，它与包含两个自由质量超多重态的作用量相一致。
We construct IIA GS superstring action on the ten-dimensional pp-wave background, which arises as the compactification of eleven-dimensional pp-wave geometry along the isometry direction. The background geometry has 24 Killing spinors and among them, 16 components correspond to the non-linearly realized kinematical supersymmetry in the string action. The remaining eight components are linearly realized and shown to be independent of x^+ coordinate, which is identified with the world-sheet time coordinate of the string action in the light-cone gauge. The resultant dynamical N=(4,4) supersymmetry is investigated, which is shown to be consistent with the field contents of the action containing two free massive supermultiplets.
