In this paper, as suggested by the classical canonical equations, a new set of the corresponding relativistic equations is set up. Therefrom a relativistic form of Heisenberg's equation is deduced. The rclalivistic Hamiltonian system of a particle according to the formulation here established has been fully discussed and by following it, however, Diracs equation appears naturally as a necessary form of relativistic wave equation tor electron in quantum mechanics.

In this paper, as suggested by the classical canonical equations, a new set of the corresponding relativistic equations is set up. Therefrom a relativistic form of Heisenberg's equation is deduced. The rclalivistic Hamiltonian system of a particle according to the formulation here established has been fully discussed and by following it, however, Diracs equation appears naturally as a necessary form of relativistic wave equation tor electron in quantum mechanics. The process of taking square root in Dirac's theory is seen to have its classical analogy. Finally, some applications of the relativistic Heisenberg's equation to Dirac's theory have been discussed and it has thereby been pointed out that this equation brings some quantities to being more symmetrical in the relativity sense and also some more general than those the non-relativistic equation can introduce.

在本文中,作者推得一组相对论式的汉密尔敦运动式;并根据此运动式,详细地讨论了一质点之运动;由此还可以很自然地看出,在量子力学中,狄拉克电子方程式似乎是一个必然的波动方程式。在狄拉克理论中的取平方根步骤在这里找到它在古典物理学中的对照。同时根据了上面的理论,作者还推得到一个相对论式的哈生堡方程式,最后则讨论了此方程式在狄拉克电子理论中的一些应用;同时并指出,在相对论的观点上,此方程式可以引导出一些比较对称的及有比较普遍形式的物理的量。

According to the theoretic basic knowlodge of the quantum mechanics and the quantum chemistry, we have not only illustrated their scientific content, but also described them in such a way as how the fundamental principles of dialectical materialism are embodied and riched, thus developing them in respect of the Marxist philosophy. This paper consists of two important parts, i.e. quantum mechanics and quantum chemistry. In the first part, we have drawn our attention to the following discussion: first, the dependence of quantum mechanics on classical-mechanics; second, the dialectical material philosophical meaning of the uncertainty principle; and third, the criticism of the indeter-minism. In the second part, we have centred our discussion on the following problems; first, the essential dependence of quantum chemistry on the theory of chemical structure of A. M. Boutlerov; second, the scientific significance of the variation method; and third, the primary criticism of the theory of electronic resonance.

依据量子力学与量子化学理论的基础知识,我们不仅论证理论本身的科学内容,而且说明如何体现及丰富了辩证唯物生义普遍原理的具体内容,因而揭露理论发展的哲学基础。本文包含着二重要组成部分在量子力学方面:着重阐述了量子力学与经典力学的关系和测不准关系的辩证唯物的哲学内容,对非决定论提出初步批判。在量子化学方面:着重阐述了量子化学与A.M.布特列洛夫的化学结构理论的本质关系和论证了近似计算方法中的变分法的科学意义,对电子共振论提出初步批判。

By combining the equation of motion of a magneto-elastically coupled system derived from a classical hamiltonian and the Maxwell equations with the propagation factor neglected, we obtained a differential equation which determines the magnetic oscillations accompanying elastic vibrations of a ferrite specimen of the usual size for magnetic resonance experiments. To each normal mode of elastic vibration of the specimen there exists an associated magnetic oscillation (namely, a magneto-acoustic mode). We...

By combining the equation of motion of a magneto-elastically coupled system derived from a classical hamiltonian and the Maxwell equations with the propagation factor neglected, we obtained a differential equation which determines the magnetic oscillations accompanying elastic vibrations of a ferrite specimen of the usual size for magnetic resonance experiments. To each normal mode of elastic vibration of the specimen there exists an associated magnetic oscillation (namely, a magneto-acoustic mode). We pointed out that the magneto-acoustic resonance phenomenon discovered by Spencer and Le Craw is a special case of the parametric oscillation involving a magnetoacoustic and a magnetostatic mode. The arrangements for observing the oscillation involving a certain magnetostatic mode and magnetoacoustic modes and the theoretical estimate of the threshold pumping power were discussed.

在本文中,我们从磁-弹性耦合的宏观表达式,通过经典场论的方法,求得弹性振动和磁振璗的耦合方程,用来分析了伴随波长约等于铁氧体样品的线度的声振动而存在的磁振璗(磁声模)。文中指出,Spencer和LeCraw所发现的磁声效应是磁声模和静磁模在注入场的激发下产生的参量振璗现象(也可以说是热声子的电磁讯号的放大)。我们引用Berk等人在讨论一种半静磁操作放大器的文章中给出的公式,算出Spencer-LeCraw实验所需要的功率,其结果与记录的数据相接近。我们提出了使任一静磁模配合磁声模产生振璗的调谐条件以及降低激发功率和观测几十到几百兆赫的声频的办法。通过磁声模和静磁模的交变场向量的空间对称性的分析,我们推导出磁声参量振璗的选择定则:对于球体三个主要弹性振动模(旋转模、向径模和椭球模),(1)静磁模(n,m,r)的Walker指标n是偶数者不产生磁声效应;(2)指标m是奇数者不与旋转模产生磁声效应,m是偶数者不与向径模或椭球模产生磁声效应。我们也举出第一类本征振动中有只可能和n是偶数、m是奇数的静磁模产生参量振璗的例子。Spencer-LeCraw局限于使静磁场调谐在(110)模上,所观察到的现象仅仅是本文所给出理...
