【摘要】 对二维圆形边界温度场声学测量方法进行深入研究,提出一种新的二维温度场区域划分方法,阐述了声学法二维圆形边界温度场重建思想。应用C++语言编制了最小二乘重建算法的程序,对单峰及双峰二维温度场进行了仿真,并对仿真结果进行分析。更多还原

【Abstract】 Two-dimensional temperature fields of circular boundary by acoustic measurement is studied,puts forward a new method to separate two-dimensional temperature field,and the idea of reconstructing two-dimensional temperature field of circular boundary by using acoustic method is expound. A programme is designed to reconstruct the temperature field by using the least square method in C++language,the simulation for two-dimensional temperature field in single peak and twin peak is done,and the simulation result is analyzed.更多还原
