Hans-Juergen Treder与爱因斯坦统一场论中禁闭的发现
Hans-Juergen Treder and the discovery of confinement in Einstein's unified field theory
摘要：
在1957年，当人们对爱因斯坦统一场论的兴趣因缺乏对其物理内容的理解而逐渐消退时，Treder对理论中四电流的可能定义进行了重要的批判性分析。作为这种审查的结果，他能够证明由E.I.H.在场方程$R_{[[μν],λ]}=0$的右边附加了适当定义的点电荷，它们与类库仑力相互作用，只要也存在与距离无关的相互力。这个不必要的，但不可避免的添加物，不能不使人们进一步怀疑爱因斯坦和薛定谔十年前所做的努力。然而在1980年，特雷德自己回忆说，他在1957年发现的势$ϕ=a/r+cr$是粒子物理学家用来从现象学上解释束缚夸克系统（如介子）光谱的势。精确解后来毫无疑问地证实，爱因斯坦的统一场论确实以一种简单的方式，已经以经典的形式，解释了由特雷德首先利用的四电流定义的极荷的限制。在本文件中提出，作为纪念，一个彻底的回忆的文章发表的特雷德在1957年，显示的方式保持他找到什么后来被公认为限制在爱因斯坦的统一场论。
英文摘要：
In the year 1957, when interest in Einstein's unified field theory was fading away for lack of understanding of its physical content, Treder performed a momentous critical analysis of the possible definitions of the electric four-current in the theory. As an outcome of this scrutiny he was able to prove by the E.I.H. method that properly defined point charges, appended at the right-hand side of the field equation $R_{[[μν],λ]}=0$, interact mutually with Coulomb-like forces, provided that a mutual force independent of distance is present too. This unwanted, but unavoidable addition, could not but lay further disbelief on the efforts initiated by Einstein and Schroedinger one decade earlier. However in 1980 Treder himself recalled that the potential $ϕ=a/r+cr$, found by him in 1957, was the one used by particle physicists to account phenomenologically for the spectrum of bound quark systems like mesons. Exact solutions have later confirmed beyond any doubt that Einstein's unified field theory does account in a simple way, already in classical form, for the confinement of pole charges defined by the four-current first availed of by Treder. In the present paper it is proposed, ad memoriam, a thorough recollection of the article published by Treder in 1957, showing the way kept by him to find what would have been later recognized as confinement in Einstein's unified field theory.
