Adsorption of single macromolecules of random and regular heterpolymers was studied by the generating functions approach (or the method of grand canonical ensemble). Adsorption of random copolymers characterized by a sequence of monomer units set as a first order Markov chain was considered using the approximation of annealed disorder and constrained annealed disorder (the Morita approximation). It was shown that use of the Morita approximation makes it possible to describe accurately the adsorption of random copolymer with a fixed (quenched) sequence of units. Adsorption of periodic heteropolymers can be described by representing the periodic sequence as a first order Markov chain with circulant transition probability matrix.

通过生成函数方法（或大正则合奏方法）研究了无规和规则杂聚物的单个大分子的吸附。使用退火无序和约束退火无序的近似（Morita近似）考虑以一组单体单元序列为一阶马尔可夫链为特征的无规共聚物的吸附。结果表明，使用森田近似法可以准确描述具有固定（淬灭）单元序列的无规共聚物的吸附。周期性杂聚物的吸附可以通过将周期性序列表示为具有循环转移概率矩阵的一阶马尔可夫链来描述。
