用边界sine-Gordon理论中边界截断共形空间方法的数值结果检验了sinh-Gordon模型中边界指数算子的一组精确形状因子，并将其与sinh-Gordon模型的解析延拓联系起来.我们发现，数值数据强烈支持的形式因素本身的有效性，但是，我们也报告了一个差异的情况下，对角矩阵元素，这仍然是悬而未决的时间。
A previously conjectured set of exact form factors of boundary exponential operators in the sinh-Gordon model is tested against numerical results from boundary truncated conformal space approach in boundary sine-Gordon theory, related by analytic continuation to sinh-Gordon model. We find that the numerical data strongly support the validity of the form factors themselves; however, we also report a discrepancy in the case of diagonal matrix elements, which remains unresolved for the time being.
