【摘要】 指出一维单原子链的格波解是由于采用了循环边界条件的结果.若采用自由边界条件,则一维单原子链将给出振动解,此解不是一种行波解,而是一种特殊的驻波解更多还原

【Abstract】 The lattice wave solution of single atomic chain only results from the cyclic boundary condition. If the free boundary condition is adopted, the vibration solution will be given. The solution is not one of traveling waves, but one of the special standing waves.更多还原
