摘　　要：传统的隧道风机风量检测方法，测定周期长，技术要求高⒚依据流体运动的能量方程，导出的静压差测定风机风量的方法。There exist long meaure period and high technical requirement in the conventional measure method of Volume flux for the tunnel driving fan. While,a new method of Volume flux of the fan measured by the static differential pressure, which is derived from the energy equations of fluid motion, can realize an instant measurement for the flux. The contrast experience of comparision the new method with the conventional method has been made in the laboratory.
