| 摘 要： | 文中采用MC80C196微处理器构成的过热蒸汽流量测量系统，实现了对过热蒸汽流量测量中的密度、流量系数、流束膨胀系数、孔径比进行在线实时校正和补偿，用软件替代以往的一些硬件设置，这样既降低测量设备的成本，减小体积，又提高了可靠性和测量精确度。

| Abstract: | IN thispaper,a new system for the measurementof steam-gas flux which was constructed by MC80 C1 96 mi- croprocessor is introduced.Mainly,aimed at the on-line correction and compensation for density of steam-gas,flux modulus,expansion modulusand aperture ratio,some of software are used,instead of date hardware configuration.So, the cost of measuring equipm ent and the volume will be decreased,meanwhile,the reliability and the precision of the measurement will be increased. |
