| 1. | In a molecule as complex as benzene a very considerable number of normal vibrational modes are possible . 象苯这样复杂的分子,可能存在很多简正震动形式。 |
| 2. | One obtain a description of the vibrational modes in terms of self-consistent oscillations of the nuclear density and potential . 借助核密度和势的自洽振荡我们便得到振动模式的描述。 |
| 3. | The vibrational modes of batio3 and pbtio3 in different crystalline phases have been investigated by means of density functional theory pseudopotential method 采用密度泛函赝势的方法,研究了不同晶相的钛酸铅和钛酸钡的振动模式。 |

| 5. | The new vibrational infrared absorption band was assigned to local vibrational modes related to the complicated complex of irradiation defects that did not contain oxygen atoms 该峰只与辐照有关,对应复杂辐照缺陷, 400退火可以基本消除。 |
| 6. | The wing is modeled structurally by vibrational modes , which are used as amplitude of motion by a finite element analysis . conservative full - potential equation and three dimensional unsteady euler equation are used to compute the unsteady transonic flows around airfoil and wings under simple harmonic motion 以给定机翼模态分布下机翼上各点的模态值作为运动幅值,以三维非定常全位势方程和三维非定常euler方程为控制方程,求解三维机翼简谐运动下的非定常气动力。 |
