To purify synthetic gases, the technique of pressure swing adsorption process is used. Three kinds of zeolite, type 13X, 5A, NaY and active carbon were used to determine the adsorption equilibrium of CO2 and CO by static(weighing)and flowing method respectively. The amounts of CO2 adsorbed with 13X zeolite and active carbon are larger than others.

This paper introduces briefly the advantages and disadvantages of these methods and the manufacturing process of MXL Type cynchronous belt with flowing method: chloroprene rubber is used as main material, glass fibre cord as the tensile member and the teeth surface covered with nylon fabric.

The experimental results of static method and flowing method showed that CLN1923 levextrel resin may separate arsenic from impure Na_2WO_4 solution effectively. In the postextraction solution, the ratio of As/W may drop to 0.003%～0006% from 0.04%～0.08%.

Use the Primal-Dual Path Flowing Method to alternate the inequation into equation and introduce impediment parameter to ensure the optimization is always in feasible region, predigest the calculation.

Thermodynamic properties of carbides present in 2.25Cr-lMo steel were determined at 985 K by a gas flowing method with fixed CH4/H2 gas mixtures and by a silica capsule method with reference alloys.

The solubility of carbon and the composition of carbides in the ferritic Fe-Mo-C system were measured at 985 K by a gas flowing method and a sealing method.

According to the thermal characteristics of the water-jacketed spherical heat conductivity test apparatus we solve the Laplace equation with twodimensional spherical coordinates. Using the Legendre polynomial, we obtain the equation to calculate the error in heat conductivity caused by the nonuniform temperature of the outer sphere.

This paper introduces a new method by which fluorescent mini-tuft is used to view the flow on the body surface and to record it by photography in low and high speed wind tunnels. The size of the fluorescent mini-tuft is about 10-20 microns in diameter. Our experiments have proved that fluorescent mini-tuft stuck on the model has no significant effects on the results of force testing. Suggest that as soon as the manufacturing of the testing model is completed, fluorescent mini-tuft be stuck on it...

This paper introduces a new method by which fluorescent mini-tuft is used to view the flow on the body surface and to record it by photography in low and high speed wind tunnels. The size of the fluorescent mini-tuft is about 10-20 microns in diameter. Our experiments have proved that fluorescent mini-tuft stuck on the model has no significant effects on the results of force testing. Suggest that as soon as the manufacturing of the testing model is completed, fluorescent mini-tuft be stuck on it so that the force measurement and flow viewing on the body surface may be carried on simultaneously.Fluoresccnl: mini-tuft has been used for viewing the flow patterns on wings of six different shapes.Three of them are selected from reference [1] so that comparison may be made between this method and the oil flow method.
