研究了考虑第一近邻和第二近邻相互作用的马氏体相变全惯性离散模型。尽管该模型在微观上是哈密顿的，但它在马氏体相界面的速度和共轭位形力之间产生了一个非平凡的宏观关系。表观耗散是由于晶格波的感生辐射将能量从前锋带走。
We study a fully inertial discrete model of a martensitic phase transition which takes into account interactions of first and second nearest neighbors. Although the model is Hamiltonian at the microscale, it generates a nontrivial macroscopic relation between the velocity of the martensitic phase boundary and the conjugate configurational force. The apparent dissipation is due to the induced radiation of lattice waves carrying energy away from the front.
