动量

In our free particle example, it turns out that it is impossible to find a wavefunction that is an eigenstate of both position and momentum.

我们以自由粒子为例，找到既有位置又有动量的波函数是不可能产生的。

For example, the free particle in our previous example will usually have a wavefunction that is a wave packet centered around some mean position x0, neither an eigenstate of position nor of momentum.

例如，在早先例子中的三个粒子将通常具有波包中心附近是某些所谓的位置x0的波函数，既不是位置特征值也不是动量特征值。

The transfer relationships between two-mode squeezed state and eigenstates of both coordinate and momentum operators are presented. Some properties of two-mode squeezed state are discussed.

导出了双模压缩态与质心系下坐标本征态和动量本征态之间的转换关系，并讨论了双模压缩态的若干性质。

The dielectric function was calculated in the momentum representation, which requires matrix elements of the momentum, q, connecting occupied and unoccupied eigenstates.

绝缘功能在动量表示需要矩阵元素的势头，问，连接占领和空态。

The position and momentum of the particle are observables.

粒子的位置和动量是可见的。

Examples of observables include energy, position, momentum, and angular momentum.

可见的例子包括能量，位置，动量，角动量。

Apart from the mathematical properties of the Dirac operator we investigate the behavior of observables such as position, velocity, momentum, describe the Zitterbewegung, and formulate the localization problem.

除了狄拉克算子的数学工具之外，我们研究诸如位置，速度，动量等看得见的客观属性，描述了颤振，并阐述一些局部问题。

This paper presents a mathematical model that employs momentum method to calculate the aerodynamic drag of the truck. This model achieves higher precision than previous methods without consideration of induced drag.

Its repertoires consist of noun,numeral and measure words.

它与表示动作行为数量的动量表示法截然不同。

Using 800MeV/c electron beam, the time resolution and attenuation length of light transition in plastic scintillators, BC408 and EJ200 packed with Al foil and Tyvek paper, are measured respectively.

利用动量为800MeV/c的电子束，对应用不同包装材料的不同闪烁体(BC408和EJ200)的时间分辨率和光传输衰减长度分别进行测量，以铝膜包装EJ200为最佳选择，其本征时间分辨率好于90ps，达到BESⅢ的设计指标。
