摘要
分析装设轴向型波纹补偿器的热力管道导向支架允许跨距以稳定性为条件的确定方法，指出有关计算公式的不确定性。
Method ids analysed for the determiantion of the allowable guiding support span of the thermal pipe with axial bellows under stable comditions.The unrealibility of the related calculation formula is deseribed.And the chart is given for maximum allowable span of guiding supports against the axial thrust.
