以光子-光子散射盒形图为例，讨论了回路积分的不同表示方法。给出了超几何表示与双对数之间的联系。构造了Mandelstam变量大值的显式解析延拓公式。
By using the example of photon-photon scattering box diagrams, different representations for loop integrals are discussed. A connection between hypergeometric representation and dilogarithms is derived. An explicit analytic continuation formula to large values of Mandelstam variables is constructed.
