标题： The propagation of waves in Einstein's unified field theory as shown by two exact solutions

摘要： 在假设度规 s_{ik}是Kursunoglu和Hély在1952-1954年间已经选定的情况下，研究了爱因斯坦统一场理论的场方程的两个精确解所显示的二维空间中波的传播。 结果显示，对于这两个精确解，选择该度规时，波的传播在波区以基本速度（ds^2=0）进行。 显示英文摘要

摘要： The propagation of waves in two space dimensions exhibited by two exact solutions to the field equations of Einstein's unified field theory is investigated under the assumption that the metric s_{ik} is the one already chosen by Kursunoglu and by H\'ely in the years 1952-1954. It is shown that, for both exact solutions, with this choice of the metric the propagation of the waves occurs in the wave zone with the fundamental velocity (ds^2=0).
