我们提出了一系列的准连续体近似的最简单的晶格模型的一个完全动态的马氏体相变在一维。近似是分散的，包括各种非经典修正动能和势能。我们表明，适定的准连续体理论可以构造在这样一种方式，相关的封闭形式的动力学关系是在一个很好的协议与离散理论的预测。
We propose a series of quasicontinuum approximations for the simplest lattice model of a fully dynamic martensitic phase transition in one dimension. The approximations are dispersive and include various non-classical corrections to both kinetic and potential energies. We show that the well-posed quasicontinuum theory can be constructed in such a way that the associated closed-form kinetic relation is in an excellent agreement with the predictions of the discrete theory.
