The Prendville growth mechanism, which assumes a linearly decreasing population growth rate, was generalized to a multicompartment system by Parthasarathy and Kumar. This article shows that their solution is only an approximate one. A diagnostic test is presented to indicate parameter vectors for which this first approximation is not very accurate. A second approximation, which overcomes some limitations of the first one, is developed and illustrated.
普伦德维尔增长机制假定人口增长率呈线性下降,帕尔塔萨拉蒂和库马尔将其推广到了多隔室系统。本文表明他们的解决方案只是一个近似解。提出了一种诊断测试,以指示第一个近似解不太准确的参数向量。开发并说明了克服第一个近似解某些局限性的第二个近似解。
