这篇文章是最近出版的第一部分的继续，目的是证明粒子的量子力学可以从新的场论中推导出来，借助于下列概念。在经典的场论处理中，我们已经证明了对应于闭合系统的解的存在，例如点电荷的解。我们假设这种代表封闭系统的解也存在于量子化场理论中。我们将证明，一个封闭系统作为一个整体，就适当选择的性质而言，在量子力学中表现为一个质点，而狄拉克理论中一些迄今尚不清楚的特征有一个自然而简单的解释。这一结果与么正场论的洛伦兹不变性密切相关。
The purpose of this paper, which is a continuation of the recently published Part I, is the proof that the quantum mechanics of a particle can be derived from the new field theory, with the help of the following conceptions. In the classical treatment of the field theory we have shown the existence of solutions corresponding to closed systems, such as that of a point charge. We assume that such solutions, representing closed systems, exist also in the quantized field theory. We shall show that a closed system as a whole, with respect to suitably chosen properties, behaves as a mass-point in quantum mechanics and that some hitherto rather unclear features of Dirac’s theory have a natural and simple explanation. This result is closely connected with the Lorentz invariance of the unitary field theory.
