采用研究非线性振动的改进Ｌ－Ｐ法研究热状态双金属条的后屈曲性质并讨论分析了变温等因素对双金属条热后屈曲的影响图１，表４，参４
The post-buckling properties of bimetal strip in hot state were studied by the improved L-P method, which studied the nonlinear vibration. The influence of temperature and other factors on the post-thermal buckling of bimetal strip was discussed. Fig.1, Table4, Reference4
