| 摘 要： | 利用具有大剪切量的横向剪切干涉法获得了有限长的水平圆管在自然对流条件下的稳态以及降温过程的实时条纹,提取出条纹相位以及背景条纹相位并将两者求差得到相位差分布,给出了经过端部效应修正后的温度场分布.实验结果表明：利用具有大剪切量的横向剪切干涉法获得的实时干涉条纹类似于利用马赫-曾德干涉仪获得的简单条纹,可以简单而精确地提...

| Abstract: | The real-time fringes during steady state and temperature decreasing processes of natural convection around finite length horizontal circular cylinder were obtained using lateral shearing interferometry(LSI) with large shearing quantity.The phases of fringes and background fringes were extracted and the phase difference distribution was obtained.The temperature distribution after edge effect correction was provided.The above experiment and analysis indicate that the similar simple real-time fringes using Ma... |
