The cross ratio he called anharmonic ratio. 他把交比叫作非调和比。
It is said to be anharmonic motion. 故称为非谐运动。
The higher-order effects of the field on the particle motion give rise to anharmonic terms in the vibrational Hamiltoniom. 场对粒子运动的高阶效应在振动哈密顿量中引起非简谐项。
The calculated anharmonic constants indicate that the anharmonic effect of (111) plane is the smallest. 由声子频率随温度变化关系得到的非谐常数表明(111)面的非谐效应最弱。
The results show that static order of Ag atoms increases,and anharmonic vibration of Ag atoms becomes stronger when Ag particle size decreases. 结果表明,随着纳米银颗粒尺寸的减小,银原子的静态无序度增大,非和谐振动加剧。
In this paper, we calculate the energy eigenvalue of a class of anharmonic oscillators by means of the self-consistent approximation. 提出了一种平均自洽方法,计算了带4次项的非简谐振子的能量本征值。
