一、湍流测量的重要性正在日益增加。湍流研究被称为流体力学中的最难课题。由于理论工作的困难,设计和制造适用的、具有我国独特风格的湍流测量仪,就成为一项有意义的工作。激光风速计正在发展,但是,它还不能代替传统的热丝风速计。热膜 First, the importance of turbulence measurements is increasing. Turbulence research is called the most difficult problem in fluid mechanics. Due to the difficulties of theoretical work, it becomes a meaningful task to design and manufacture a suitable turbulence measuring instrument of our unique style. Laser anemometers are evolving, however, but they are not a substitute for conventional hot wire anemometers. Hot film
