1.DIMENSIONLESS COEFFICIENT METHOD OF DESIGNING THE WELDING SECTION OF AXIAL PRESSURE COMPONENT WITH H SHAPE
3.In this paper,conventional testing instruments and calculating methods for the water vapor pressure component are analyzed and discussed. In addition,a more precise testing instrument and the corresponding calculating method,recommended by the Central Meteorological Bureau (CMB),are introduced. Last,the way to select a testing instrument or to design a self made one is given so that the instrument might be the fittest for the general or simulated atmosphere conditions when field determination is conducted in IC engine testing.
6.The catalyst was prepared with Cu,Fe,Mn,Mo as main active components and γ-Al_2O_3 as carrier,and used in the treatment of DSD wastewater under high temperature and pressure. The effects of active component proportion and calcining temperature on the activity and stability of the catalyst were studied.
