surface of constant surface
1.There were some what degree displacement of ZPC from the the values of Zero Point Of Titration for both soils, whose follow the trend of A horizon > Bw horizon > C horizon. It stated that the colloids of both soils belong to the compound type of constant surface charge and constant surface potential soil colloids.
2.The preparing method for molybdenum disulfide of lubricant grade and lubricants containing molybdenum disulfide are presented,such as grease of constant volocity joint anti-seizing lipstick paste,waterborme lubricant,enviranmentally safe lubricunt,ballistics with molykote composition and molybdenum disulfide for surface treatment of metallic material and alloy material.
3.The results of experiments show that the rate of the water evaporation in the HVEF is about 1.4 times of the rate of the controls under the experiment conditions. When the distance between the single point pole and the surface of the distilled water is constant, the rate of the vaporization increases nonlinearly with the supplied voltage.
4.The surface panel method has been applied to predict the hydrodynamic performance of highly skewed propeller.The surface of propeller and its trailing vortex are discreted by a number of small hyperboloidal quadrilateral panels with constant source and doublet distribution.For highly skewed propeller,the conventional method generating grid oriented along constant radii will result in a high aspect ratio and a high skewness and a twist panel near the propeller tip on blade surface,which result easily in incorrect calculation results of velovity on blade surface,even in iteration divergence and calculation failure.A “non-conventional grid” is developed to acoid these problems.This grid can effectively solve the problem of the calculation and convergence for highly skewed propeller.The non-linear Kutta condition of equal pressure on upper and lower at the trailing edge is executed by the iterative procedure.By sample calculating,the obtained results are satisfied the experimental data.
6.TiO_2 composite film containing P and Ca was prepared on surface of medical Ti materials by microarc oxidation with constant voltage. The effects of anode voltage on the morphology, phase constituent and Ca, P content in the oxide films were investigated by SEM, XRD and EDS, focusing on the Ca and P content disposition regularity in the oxide film surface and in intra-pore.
8.WT5”BZ]:The thiol-terminated β-cyclodextrin derivative (β-CDd) was attached to the surface of gold electrode of quartz crystal resonator by self-assembly. The inclusion reactions of benzene derivatives and naphthalene derivatives with β-CDd were monitored in situ by using quartz crystal microbalance (QCM). The influences of temperature, concentration, the number of substituting groups and its positions on an aromatic ring on the inclusion constant and the rate constant were investigated.
10.Such an anomalous dielectric response for the BST films is ascribed to the formation of the Schottky barrier between the metallic electrode and the film surface, and the existence of the mobile charges in the film as indicated by the frequency characteristics of dielectric constant changing as the applied dc bias.
