We had investigated an unsteady phase transition phenomenon of an atomic layr which is irradiated by thermal radiation and is being melted, on bases of an electromagnetic theory and a molecular dynamics (MD). This project is on the extention of that work, where is requested a development in a new thermal conduction technique for investigating the dynamics of phase transition and radiation phenomenon, particularly a relationship between the solidification and the radiation emission cooling in a nm-scale atomic system. The real atomic system of a finite size and in a solid state is pressed anisotropically and includes crystal defects. It has a temperature distribution in it. Thermal energy flows inhomogeneously. The MD simulation on such a phenomenon is related to a macrophenomenon on the thermal contact resistance of solid surfaces. First, we prese nted new techniques for a pressure-control-type strain application and for a quasi-static scanning of applied anisotropic pressure, and investigated an unsteady process of elastic and/or plastic deformation in a pressure applied atomic system.Second, we investigated the unsteady behavior of temperature distribution and thermal energy flow in such an atomic system.

基于电磁场理论和分子动力学理论，研究了原子层在热辐射作用下熔化过程中的非稳态相变现象。该项目是该工作的延伸，要求开发一种新的热传导技术，用于研究相变和辐射现象的动力学，特别是纳米尺度原子系统中凝固与辐射发射冷却之间的关系。有限尺寸的固态真实的原子系统被各向异性地挤压，并且包括晶体缺陷。它有一个温度分布。热能不均匀地流动。对这种现象的分子动力学模拟与固体表面接触热阻的宏观现象有关。首先，我们提出了压力控制型应变施加和各向异性压力准静态扫描的新技术，研究了压力作用下原子系统的非稳态弹性和/或塑性变形过程，其次，我们研究了压力作用下原子系统的温度分布和热能流的非稳态行为。
