In principle, the theoretical study of any molecular system requires the solution of the time-dependent Schr\u00f6dinger equation. However, in practice, more attention is paid to the trajectory of the nucleus. Such a trajectory can be obtained by solving the classical mechanical equation of motion using the Born-Oppenheimer approximation. Alder and Wainwright have said that computer simulation experiments will become an important bridge connecting macroscopic experimental phenomena and microscopic nature. After 10 years of their first molecular dynamics simulation experiments, French physicist Verlet proposed an integration algorithm for Newton&#8217;s equations of motion. At the same time, another set of algorithms for generating and recording pairs of neighboring atoms is proposed, which greatly simplifies the calculation of the interaction between atoms. These two algorithms are still widely used in practice in some variants [1, 2].<\/div>\n<div>A variety of atomic-level simulation methods have been developed over the past few decades, including lattice statics, lattice dynamics, Monte Carlo, and molecular dynamics. Among them, molecular dynamics is especially suitable for the study of plastic deformation. It studies the real-time behavior of deformation process through the solution of Newton&#8217;s equation of the atomic interaction system of some defined interatomic interaction potential functions, and includes the non-simplification of the lattice. Harmonicity, height unevenness of internal stress, and transient response of the system.<\/div>\n<div>\u5206\u5b50\u52d5\u529b\u5b66\u306f\u3001\u4e3b\u306b\u30cb\u30e5\u30fc\u30c8\u30f3\u529b\u5b66\u306b\u4f9d\u5b58\u3057\u3066\u5206\u5b50\u30b7\u30b9\u30c6\u30e0\u306e\u904b\u52d5\u3092\u30b7\u30df\u30e5\u30ec\u30fc\u30c8\u3057\u3001\u5206\u5b50\u30b7\u30b9\u30c6\u30e0\u306e\u3055\u307e\u3056\u307e\u306a\u72b6\u614b\u3067\u69cb\u6210\u3055\u308c\u308b\u30b7\u30b9\u30c6\u30e0\u304b\u3089\u30b5\u30f3\u30d7\u30eb\u3092\u62bd\u51fa\u3057\u3001\u305d\u308c\u306b\u3088\u3063\u3066\u30b7\u30b9\u30c6\u30e0\u306e\u914d\u7f6e\u7a4d\u5206\u3092\u8a08\u7b97\u3057\u3001\u3055\u3089\u306b\u914d\u7f6e\u306e\u7d50\u679c\u306b\u57fa\u3065\u3044\u3066\u30b7\u30b9\u30c6\u30e0\u3092\u8a08\u7b97\u3057\u307e\u3059\u7a4d\u5206\u3002\u71b1\u529b\u5b66\u91cf\u3068\u305d\u306e\u4ed6\u306e\u5de8\u8996\u7684\u7279\u6027\u3002\u539f\u5b50\u6838\u3068\u96fb\u5b50\u3067\u69cb\u6210\u3055\u308c\u308b\u591a\u4f53\u7cfb\u306e\u904b\u52d5\u65b9\u7a0b\u5f0f\u3092\u89e3\u304d\u307e\u3059\u3002\u591a\u6570\u306e\u539f\u5b50\u7d44\u6210\u306e\u30b7\u30b9\u30c6\u30e0\u30c0\u30a4\u30ca\u30df\u30af\u30b9\u554f\u984c\u3092\u89e3\u304f\u3053\u3068\u304c\u3067\u304d\u308b\u8a08\u7b97\u624b\u6cd5\u3067\u3059\u3002\u7269\u8cea\u306e\u5de8\u8996\u7684\u306a\u9032\u5316\u7279\u6027\u3092\u76f4\u63a5\u30b7\u30df\u30e5\u30ec\u30fc\u30c8\u3067\u304d\u308b\u3060\u3051\u3067\u306a\u304f\u3001\u30c6\u30b9\u30c8\u7d50\u679c\u3068\u3082\u4e00\u81f4\u3057\u307e\u3059\u3002\u540c\u69d8\u306e\u8a08\u7b97\u306b\u3088\u308a\u3001\u5fae\u7d30\u69cb\u9020\u3001\u7c92\u5b50\u904b\u52d5\u3001\u304a\u3088\u3073\u5de8\u8996\u7684\u7279\u6027\u3068\u306e\u95a2\u4fc2\u306e\u660e\u78ba\u306a\u30a4\u30e1\u30fc\u30b8\u3082\u5f97\u3089\u308c\u3001\u65b0\u3057\u3044\u7406\u8ad6\u3084\u6982\u5ff5\u306e\u958b\u767a\u306b\u5f37\u529b\u306a\u6280\u8853\u30b5\u30dd\u30fc\u30c8\u3092\u63d0\u4f9b\u3057\u307e\u3059\u3002<\/div>\n<div>\u5206\u5b50\u52d5\u529b\u5b66\u306e\u5bfe\u8c61\u306f\u7c92\u5b50\u7cfb\u3067\u3059\u3002\u30b7\u30b9\u30c6\u30e0\u5185\u306e\u539f\u5b50\u9593\u306e\u76f8\u4e92\u4f5c\u7528\u306f\u3001\u30dd\u30c6\u30f3\u30b7\u30e3\u30eb\u95a2\u6570\u306b\u3088\u3063\u3066\u8a18\u8ff0\u3055\u308c\u307e\u3059\u3002\u3057\u305f\u304c\u3063\u3066\u3001\u30dd\u30c6\u30f3\u30b7\u30e3\u30eb\u95a2\u6570\u306e\u30bf\u30a4\u30d7\u3068\u305d\u306e\u30d1\u30e9\u30e1\u30fc\u30bf\u30fc\u3092\u6b63\u3057\u304f\u9078\u629e\u3059\u308b\u3053\u3068\u306f\u3001\u30b7\u30df\u30e5\u30ec\u30fc\u30b7\u30e7\u30f3\u7d50\u679c\u306b\u304a\u3044\u3066\u91cd\u8981\u306a\u5f79\u5272\u3092\u679c\u305f\u3057\u307e\u3059\u3002\u307b\u3068\u3093\u3069\u306e\u5834\u5408\u3001\u30dd\u30c6\u30f3\u30b7\u30e3\u30eb

In principle, the theoretical study of any molecular system requires the solution of the time-dependent Schr\u00f6dinger equation. However, in practice, more attention is paid to the trajectory of the nucleus. Such a trajectory can be obtained by solving the classical mechanical equation of motion using the Born-Oppenheimer approximation. Alder and Wainwright have said that computer simulation experiments will become an important bridge connecting macroscopic experimental phenomena and microscopic nature.
