我们提出了一个研究的世界表，描述了各种字符串散射过程的经典极限。我们的主要重点是在AdS时空中的弦散射，因为它的关系，通过AdS/CFT（antichar 21 {}de Sitter/conformal field theory）对应的胶子散射在$mathcal{N}=4$超对称杨-米尔斯理论。但我们也考虑类似的过程中，我们比较平坦的闵可夫斯基时空的AdS的情况。除了散射的字符串串，我们还发现和研究世界表描述的散射字符串的外部来源。
We present a study of the worldsheets that describe the classical limit of various string scattering processes. Our main focus is on string scattering in AdS spacetime because of its relation via the AdS/CFT (antichar21{}de Sitter/conformal field theory) correspondence to gluon scattering in $mathcal{N}=4$ supersymmetric Yang-Mills theory. But we also consider analogous processes in flat Minkowski spacetime which we compare to the AdS case. In addition to scattering of string by string we also find and study worldsheets describing the scattering of a string by external sources.
