本世纪三十年代以来，无缝线路稳定问题一直受到世界各国学者的重视。但由于问题的复杂性，这个认识过程至今还没有完结。本文不拟对这个问题进行广泛地讨论，仅参考英、美等国近十余年来发展的一种无缝线路稳定计算的数值计算法，对比国内统用无缝线路稳定计算公式（统一公式 Since the thirties of this century, the problem of the stability of the seamless line has always been valued by scholars all over the world. However, due to the complexity of the issue, the process of awareness has not yet ended. This article does not intend to discuss this issue extensively, only with reference to the numerical calculation method of seamless line stability calculation developed in Britain and the United States for more than ten years. Compared with the formula Unified formula
