本文对红外热图测热技术与应用前景、红外热像仪主要部件与性能指标、红外测热数据处理软件功能模块与实现、风洞试验设备与测量系统等进行了论述，测量了模型表面发射率并对发射率随极角变化的三种修正方法进行了对比，对一维热传导分析中模型壁厚半无限假设、壁面热流定常假设、绝热壁温选取等进行了探讨。 - After research surface reconstruction with triangular facets , contours of first layer and the last layer are triangulated with layer separation algorithm firstly . and then the least polar - angle criterion is presented for linking two convex contours , and the method is also given in which non - convex contour is transformed to a set of convex contour . with the splitting and integrating algorithm , the single - to - multi - contour reconstruction with triangular facet has been simplified to one - to - one contour
首先采用层析式算法对起始层和结束层中的轮廓进行三角剖分；然后采用最小极角法实现两凸轮廓间的三角片重构，并讨论了非凸轮廓变换为凸轮廓的方法；最后，使用分裂与合并技术将单轮廓匹配多轮廓的三角片重构简化为单轮廓之间的三角片重构，最终完成整个骨骼表面的三角片重构。
