在冰川冰体的流动中观察到许多有趣的现象。为了建立一个合理的理论来研究这些现象，我们在这里发展了一个详细的连续介质模型的流动多温（即。e.部分寒冷，部分温和）在宽的山谷中的冰川。作为分析该模型所提出的非线性双自由边界问题的第一步，在一个特殊的非常简单的极限情况下，研究了解的结构和稳定性。进一步的分析将推迟到本文件第二部分。
Many interesting phenomena have been observed in the flow of glacial ice masses. In order to establish a rational theory for the study of these phenomena, we develop here a detailed continuum model for the flow of polythermal (i. e. partially cold and partially temperate) glaciers in wide mountain valleys. As a first step in the analysis of the nonlinear double free boundary problem posed by this model, the structure and stability of solutions are studied in a particular very simple limiting situation. Further analysis is deferred to part II of the paper.
