thermal mapping technique meaning in Chinese
热测绘技术
Examples
- Surface temperature measuring techniques can be divided into the catogeries of point and thermal mapping techniques
一类是点测量技术，每次只能测量模型表面有限的离散点的温度。 - By way of the point measuring techniques the surface temperature of only finite points on a model was measured every time , while with the thermal mapping techniques the surface temperature of whole a model was obtained
另一类为热成像测量技术，能获得整个模型表面的温度分布，包括涂层热成像法和红外热成像法两类。 - The tests were conducted in the hypersonic low density wind tunnel at nominal test conditions of mach 16 , stagnation temperature 923k , stagnation pressure 1 . 40mpa and 7 . 30mpa . heat - transfer data were obtained on a hemisphere model , a sharp cone and a big blunt cone respectively by means of infrared thermal mapping techniques , that of a 0 . 5mm thickness blunt cone by virtues of thermocouples . furth ermore , heat - transfer on all those models was calculated with the theoretical method
最后在名义m _ = 16 、 t _ 0 = 923k 、 p _ 0 = 1 . 40mpa及7 . 30mpa的高超声速低密度风洞中，利用红外热图技术获得了半球圆柱、尖锥、大钝头三个模型表面热流分布，利用薄壁法技术得到了一壁厚为0 . 5mm的钝锥模型表面的热流分布，并通过工程理论方法计算了模型表面的气动热，把理论计算结果与上述试验结果比较，几者符合得较好。 - The demonstration of heat - transfer measuring techniques and prospect of infrared thermal mapping techniques , main parts and performance indexes of a infrared camera , functional blocks and implementation of infrared processing software , experimental facility and measuring system of the wind tunnel has been made . the model emittance was experimentally determined and the three methods correcting directional emittance were compared . those problems of the infinite - slab model thickness and constant wall heat rates hypothesis , the determination of adiabatic wall temperature were discussed in a 1 - d heat conduction analysis
