摘要：
流体的结构特性，其分子通过潜在的硬核心加上n分段恒定的部分不同的宽度和高度的相互作用，使用（半解析）的有理函数近似方法。结果示出的情况下，一个方肩加方势阱和移位方势阱和模拟数据和那些遵循的（数值）解决方案的打击-Yevick积分方程进行比较。
英文摘要：
The structural properties of fluids whose molecules interact via potentials with a hard-core plus n piece-wise constant sections of different widths and heights are derived using a (semi-analytical) rational-function approximation method. The results are illustrated for the cases of a square-shoulder plus square-well potential and a shifted square-well potential and compared both with simulation data and with those that follow from the (numerical) solutions of the Percus-Yevick integral equation.
