晶体的表面弛豫和表面重构现象导致了MD模拟中体系总内能的升高。
The surface relaxation and reconstruction are reproduced in the NEMD computational approach, which leads to the increase of system energy during simulation.

虽然由于缺少质子，两个序列都显示为低信号。高信号可以用钙盐颗粒沉积于脑内所致的表面弛豫效应来解释。
Although there is usually low signal on both sequences due to a paucity of protons, high signal can be explained by a surface relaxation effect by the calcium salt particle precipitated in the brain.
3
不同表面结果的比较显示弛豫及重构对表面声子性质具有决定性的影响。
The results for different surfaces show the important effects of surface relaxation and reconstruction on the properties of surface phonons.

表面弛豫
学科：地球物理勘探词目：表面弛豫英文：surface relaxation 释文：表面弛豫是指岩石颗粒表面对弛豫过程的影响。表面原子的受力情况和体内不同造成的的表面原子层相对于体内原子层下的整体移动以降低体系的能量，而表面原子的近邻数和旋转对称性均不改变的现象，这种现象称为表面弛豫。
