Based on application of 3D body-fitted numerical grid with a curvilinear coordinates system and the theories about turbulent flow and the laminar flow, the new techniques that the independent variables were expressed by co-variable velocities were applied to solve the problems about flow around a high-speed car body for the first time.

采用当今数值新技术，较为全面和深入地研究了高速汽车车身绕流问题。本文依据k-ε双方程湍流模型和附面层理论，采用先进的曲线坐标系下的贴体与边界正交数值网格技术，首次把以协变速度分量作为独立变量的数值技术运用于汽车车身绕流问题的求解。

The present invention relates to a coating composition comprising; A at least one polyester oligomer prepared from reactants comprising a 20 60 wt.% of at least one polyol, b 5 30 wt.% of at least one polycarboxylic acid selected from the group of cyclic polycarboxylic acids, the esters or the anhydrides thereof, wherein the carboxyl groups are separated by 3 carbon atoms or less, and from the group of alpha , beta -saturated acyclic polycarboxylic acids, the esters or the anhydrides thereof, and c 20 60 wt % of at least one monocarboxylic acid, the sum of the wt.% indicated for the reactants,, and always being 100 wt.%, and the oligomer being a low-viscosity oligomer having a weight average molecular weight Mw of less than 5,000, and a hydroxyl number in the range of about 200 to about 400 mg KOH/g oligomer, and B at least one polyisocyanate.

本发明涉及一种包含如下组分的涂料组合物：A至少一种由包含如下成分的反应物制备的聚酯低聚物：a20-60wt％至少一种多元醇，b5-30wt％至少一种选自其中羧基被3个或更少碳原子隔开的环状多元羧酸、其酯或酸酐以及选自α，β-饱和的无环多元羧酸、其酯或酸酐的多元羧酸，以及c20-60wt％至少一种一元羧酸，其中反应物、和的wt％之和总是为100wt％，所述低聚物是重均分子量Mw低于5000且羟基值为约200-约400mg KOH/g低聚物的低粘度低聚物，以及B至少一种多异氰酸酯。

Work in this paper focuses on the data mining from chromatographic retention index data. A retention index database that contains about 50000 records of retention index is firstly established. Projection pursuit technique is then utilized to do data mining upon the data in order to find out some valuable information about the relationship between the retention indices and structural descriptors. A novel algorithm for projection pursuit is developed in this work. Samples of alkane, alkene and cycloalkane are investigated.

The age of adakitic dacite is about 514.2±8.5 Ma, and the age of eclogite from the northern margin of Qaidam basin is 494.6±6.5 Ma. Therefore, it is considered that the slab started its subduction in Late Cambrian, that the adakitic magma was formed at the subduction depth of about 75~85 km, and that the partial melting residues with garnet facies continued subducting and finally formed eclogite in Early Ordovician.
