查询词典 Planck constant

The 1s electron cloud in hydrogen atom has the largest probability density distribution around a spherical shell with Bohr radius a 0. The author thinks the probability density distribution and electron cloud belong in fact,to statistic regularity, and imply a macro-time scale is used, therefore in hydrogen molecule the product of energy and time is far larger than Planck Constant.

氢原子中 1s电子的电子云呈球形，电子的最大几率密度分布出现在玻尔半径a0 的球壳内，认为几率密度分布及电子云属统计规律，意味着已经使用了宏观时标，这样就使氢分子体系中能量和时间的作用量远大于普郎克常数；根据电子云的交叠，用经典力学计算了基态氢分子的结构常数，获得键长、键能及力常数的表达式分别为Re=2a0 ，De=ze/4 2a0 ，k=ze/2 2a30 ，采用原子单位 a 。u 。

Below we will use "Medicine Phantom Physics" test the photoelectric effect and the Planck constant determination analyze.

"E"为光能；"h"为普朗克常数，表示光的粒子特征；"υ"为光的频率，表示了光的波的特征。

There are four basic constants in natural units system: Planck constant , speed of light in the vacuum c, the quality of any particle and electron's electric quantity e. Other units can be educed by the four basic units.

自然单位制有四个基本常数：普朗克常数、真空中的光速c、任意粒子的质量和电子的电量e，其它单位都可以由这四个基本单位导出来。

The time evolution of expectation values of the basic dynamic variables in a quantum system under different effective Planck constant were compared with the exact values of the basic dynamic variables in classical system. It is found, for the regular motion, the difference comes from the quantum effect; for the chaotic motion, it comes from the dynamical effect and the destruction of the dynamical system.

通过引入等效普朗克常数，将量子系统中基本动力学变量的期望值和经典系统中基本动力学变量的精确值的时间演化行为相比较，分析了两者产生差异的因素，规则运动主要是和量子效应有关，而混沌运动则是和动力学效应有关，即与系统的动力学对称性破坏相联系。
