在络合物化学中Bjerrum提出的生成函数是一个重要的基本函数。但是其性质却研究得很少(原因之一是函数关系较为复杂)。本文用数学证明的方法来探讨它的性质。设溶液中金属离子为M(略去电荷,下同),配位体为L。C_M、C_L分别是它们的总浓度。[M]、X、[M L_i]分别代表游离金属离子、游离配位体L、 The generation function proposed by Bjerrum in complex chemistry is an important basic function. But its nature is studied very little (one of the reasons is the function of the more complex). In this paper, the method of mathematical proof to explore its nature. Set the solution of metal ions M (omitted charge, the same below), ligand L. C_M, C_L, respectively, their total concentration. [M], X, [M L_i] stand for free metal ion, free ligand L,
