  1. Using mass flux controller ( mfc ), gas regulation system achieved accurate mix of two kinds of gases, steel bottle gas ( some compressed gas ) and zero air ( pure air ). for the sake of data transmission between dynamic air regulator and other equipments in the monitoring air quality system, normal digital interface ( rs - 232c ) make correlative role of communication interface so that automatic survey could be achieved

    本儀器採用國際先進的自動控制配氣原理,採用精密質量流量控制器( mfc )來控制鋼瓶氣(某種壓縮氣體)與零空氣(純凈無污染的空氣)的混合比來得到精確濃度的校準氣體,以便於對各種氣體監測儀進行高精度校準。
  2. Aimed at some problems such as short spraying distance, electricity - leaking and reverse ionization among electrostatic nozzles existing in the country, a induction charging and pneumatic energy electrostatic nozzle was designed. the basic designing theories, structure and working process of this nozzles were theoretically specified in the paper. and then the atomization quality and charge performances of this nozzle and its affecting factors were studied by carrying out performance experiment and statistic analysis. result of the studies indicate : ( 1 ) some progress were made in solving the problems list above ; ( 2 ) from this nozzle, droplet were minute and uniform, and higher charge - mass ratio can be obtained under lower electrostatic voltage, thus the atomization quality and charge performance of this nozzle were both better ; ( 3 ) within the experiment extend, air pressure at 0. 2mpa, electrostatic voltage at 2400v were the most suitable parameters for the nozzle ; ( 4 ) the regression equations for describing droplet size, intensity of spray current and charge - mass ratio of this nozzle obtained from the experiment data had higher forecast precision ; ( 5 ) cross - effect of all factors were not significant, the atomization quality and charge performance were relative dependency affected by the factors

    諸試驗因素中,充電電壓和噴孔直徑對霧滴荷質比均有極顯著的影響;氣體壓力和液體流量對霧滴荷質比的影響均不顯著;影響霧滴荷質比的主要因素依次為充電電壓和噴孔直徑; ( 8 )在300v 、 600v 、 1200y 、 1800y 、 2400v 、 3000v六種充電電壓t ,霧滴荷質比先隨充電電壓的增加而增大, 2400v后荷質比減小,推測:對于所研製的噴頭可能存在一個最佳充電電壓; ( 9 )由充電電壓和噴孔直徑的不同搭配所得霧滴荷質比不同這一結果,可看出,較大充電電壓需配備較大噴孔直徑以增強霧滴荷電效果; ( 10 ) td3 . 6和td3 . 4兩噴頭的霧滴荷質比曲線趨于重合,說明噴孔直徑大於滬3
