By using the FINE/Turbo analysis software of Numeca,the present paper numerical simulates the four original and their optimum blade profiles with three-dimensional computation,and compares the aerodynamic characteristics with different Mach numbers and different incidences.

For investigating the profile that has advanced startup characteristic with the supersonic and transonic conditions, the present paper design the suction surface as the“concave”type based on a transonic profile,and analysis the changing of the aerodynamic characteristic of the original and the remodeled cascades,so gives a thoughtway for designing the blade profiles.

To form software for design optimization of compressor blade profiles,the IGA is combined with the above blade profile parameterization and flow field calculation method.

The designed efficiency method of 7-40 sintering blower model using “equal deceleration flow model" is carried out, and compare the model with conventional designed through test research many times, the method of design and draw profile using "equal deceleration flow model" are obtained.

The aerodynamic characteristics of the profile NACA0015 with steady suction air on the profile surface have been investigated by numerical simulating the flow fields around the profile under different low Mach Numbers.

For understanding the aerodynamic characteristics of the blade cascade with aft-loading profiles, the experimental investigations were carried out on the low speed annular wind tunnel with the conventional straight blades and the curved blades cascades that have the aft-loading profiles.

Based on the research on the motion law of the drilling fluid along the blade, the necessary condition of the blade shape for a high efficiency turbodrill is obtained.

TBM-6 type blade shape measure Instrument for hydraulic turbine runner and its application were introduced in this paper.

The research and application of the TBM-6 type blade shape measure Instrument for hydroturbine runner were introduced in this paper.

Determination of Protein Content in Different Leaf Types of Pinellia ternata

The results indicate that more attention should be paid on increasing leaf length but keeping the present leaf curvature for leaf type,on increasing the thickness of basal internode and the length of the internode below panicle for stem type,and on increasing grains per panicle and branch number for panicle type in early season indica rice breeding.
