From this point of view,it ispointed out that there are two kinds of commonalities among diverse prob-lems,one is the relative commonality and the other is the homogenous co-mmonality,and it is advanced that the approach to effectively make useof the relative commonality is to divide models suitably and to set up theorganic relation between models convenient to their composite conection oncondition that models are shared,and the approach to effectively make useof the homogenous commonality is from the view point of different problemsneeding their special models for solving,to convert their special modelrepresentation to comparatively general model depth representation on theprinciple of independence and share of commonality.The articles in thepast has made deep and complete research on model management in aspectssuch as model division and compositive conection,and a number of theoriesand methods are provided,but none of them is in relation to model depthrepresentation.

从这一角度出发，作者指出，在多样性问题中存在两种共性，一种是问题相关共性，另一种是问题同构共性，并提出有效利用问题相关共性的方法是在实现模型共享的前提下对模型进行合理划分和建立便于模型复合联接的各模型之间的有机联系，而有效利用问题同构共性的方法则是从不同问题求解本质上需要的专用模型出发，根据独立与共享原理，将这些专用模型表示转化成较为通用的模型深层表示，以往的文献在模型划分、复合联接等诸方面对模型管理进行了较为深入全面的研究，并从这一角度提出了许多模型表示的理论和方法，但对模型深层表示方面尚没有涉足。
