本文提出了一个程序来数值研究有质量可积二维相对论场论中的关联函数。它依赖于严格的形状因子的领域，可以重建从因式分解的散射数据。相关函数可表示为在中间渐近状态上的无穷和。我们建议使用计算机的力量来执行的总和数字。的收敛性的总和进行测试的最简单的例子缩放伊辛自旋自旋相关性（无磁场）。
A program is proposed to study numerically the correlation functions in massive integrable 2D relativistic field theories. It relies crucially on the exact form factors of fields which can be reconstructed from the factorized scattering data. The correlation functions are expressible as infinite sums over intermediate asymptotic states. We suggest using computer power to perform the summation numerically. The convergence of the sum is tested for the simplest example of the scaling Ising spin-spin correlations (without magnetic field).
