采用简立方格点上的MonteCarlo模拟 ,研究一端被无限大不可穿透平面壁吸附的高分子链的均方末端距〈R2 〉 ,以及高分子链的质量中心到平面吸附壁的平均距离〈Z〉 ,与链长N、参数u(u =e-ε/kT,ε是链骨架原子间的相互作用能量 ,k是玻耳兹曼常数 ,T是热力学温度 )的关系。结果表明 :〈R2 〉和〈Z〉都服从标度律 ,〈R2 〉 =αNγ,〈Z〉 =βNη,其中 ,γ、η、α、β都是u的函数 ;u从1减小到 0 5,则γ从 1 0 1增大到 1 19,η从 0 51增大到 0 60 .
Monte Carlo simulations on simple grid points are used to study the mean square end distance of polymer chains adsorbed at one end by an infinitely large number of plane walls and the average distance from the mass center of the polymer chains to the plane adsorption wall , And the chain length N, the parameter u (u = e-ε / kT, ε is the energy of interaction between chain skeleton atoms, k is the Boltzmann constant and T is the thermodynamic temperature). The results show that both and obey the scaling law, = αNγ, = βNη, where γ, η, α and β are all functions of u; u decreases from 1 to 0 5, γ increases from 1 0 1 to 1 19 and η increases from 0 51 to 0 60.
