摘　　要：我国石化行业装置日趋大型化和高参数化,建立一套行之有效并操作简单的高温分析方法迫在眉睫。在充分了解各国规范中高温分析方法的原理和优缺点后,国内分析设计标准宜适时引入完整的高温分析方法来指导工程应用。提议并探讨了高温分析的制定原则、主要方法、步骤框架及后续工作等方面的问题,可为将来国内分析设计标准引入高温分析方法提供参考。With the development of the large scale and high parameters in Chinese petrochemical industry,it is urgent to establish a set of effective and simple methods for elevated temperature analysis. After adequate understanding of the principles and merits and demerits of the elevated temperature analysis methods in the codes of many countries,Chinese national standards have introduced the complete methods of elevated temperature analysis in due time to guide engineering application. In this paper,the formulation principle,main methods,steps and framework,subsequent works,etc. of elevated temperature analysis are discussed,which can provide helpful references for introduction of elevated temperature analysis method in the domestic standard in the future.
