摘　　要：为深入挖掘燃烧室出口温度场试验数据中所隐含的内在信息,基于数理统计理论和燃烧室出口温度场的分布特性,总结归纳了大量温度场数据的分析方法。并通过联机分析处理(On-Line Transaction Processing,OLAP)技术的思路形成涵盖整体、局部、微观、动态4个维度的温度场数据分析体系。并以某燃烧室的出口温度场数据为例阐述了该分析方法的内涵,使该温度场数据被多角度、多侧面、多层次的考察分析,验证了该分析方法的有效性。最后对多维度分析方法在温度场特性研究、无量纲化的比较、差异的量化分析等方面的应用进行了初步探索。In order to dig the inherent information thoroughly implied in the test date of combustor exit temperature field,a number of analytical methods were summarized,that based on the statistics theory and the distribution characteristics of combustor exit temperature field.And with the help of OLAP technical idea,the temperature field data analysis system covering whole,local,micro,dynamic four dimensions is formed.Finally,a preliminary exploration on application of multi-dimensional analysis in temperature field features research,dimensionless comparison,quantitative analysis of differences and other aspects are carried out.This study can be used for the assessments of combustor temperature field.It also provides the ideas and methods for law exploration and product optimization.
