A PENALTY TECHNIQUE FOR NONLINEAR COMPLEMENTARITY PROBLEMS

引用

Journal of Computational Mathematics 1998年第1期16卷 40-50页

作者： Li, DH Zeng, jp Hunan Univ Dept Math Appl Changsha Peoples R China

In this paper, we first give a new equivalent optimization form to nonlinear complementarity problems and then establish a damped Newton method in which penalty technique is used. The subproblems of the method are lower-dimensional linear complementarity problems. We prove that the algorithm converges globally for strongly monotone complementarity problems. Under certain conditions, the method possesses quadratic convergence. Few numerical results are also reported.

Numerical Simulation of Sub-cooled Cavitating Flow by Using Bubble Size Distribution

A new cavitating model by using bubble size distribution based on mass of bubbles is proposed. Liquid phase is treated with Eulerian framework as a mixture containing minute cavitating bubbles. Vapor phase consists of various sizes of minute vapor bubbles, which is distributed to classes based on their mass. The change of bubble number density for each class was solved by considering the change of bubble mass due to phase change as well as generation of new bubbles due to heterogeneous nucleation. In this method the mass of bubbles is treated as an independent variable, in other word, a new coordinate, and dependant variables are solved in Eulerian framework for spatial coordinates and bubble-mass coordinate. The present method is applied to a cavitating flow in a convergent-divergent nozzle, and the two-phase flow with bubble size distribution and phase change was successfully predicted.

Crystal structure of the complex of trichosanthin with NADPH at 0.172 nm resolution

引用

Chinese Journal of Chemistry 1997年第3期15卷 265-277页

作者： Xiong, jp Xi, ZX Wang, Y CHINESE ACAD SCI SHANGHAI INST ORGAN CHEMSHANGHAI 200032PEOPLES R CHINA

The orthorhombic crystal structure of the complex of trichosanthin with nicotinamide adenine dinucleotide phosphate has been determined by molecular replacement method using one of the molecules of the monoclinic crystal structure of trichosanthin at 0.27 nm resolution as the search model. The crystallographic refinement at 0.172 nm resolution led to a final R-factor of 17.4% with root-mean-square deviations of 0.0013 nm and 3.8 degrees from the ideal bond lengths and bond angles, respectively. The quality of the structure, the polypeptide chain fold and the comparison of it with that of the monoclinic trichosanthin structure, the location of nicotinamide adenine dinucleotide phosphate, the active site structure as well as the solvent structure are described.

1 Introduction and main resultsARVESON in ref. [1] generalized the classical Hahn-Banach Extension Theorem for linear func-tionals to the self-adjoint linear closed subspace of C~* -algebras. From then on numerous au-thors have given various generalizations of the non-commutative Hahn-Banach-Arveson Theo-rem of ref. [1]. The following extension theorem is due to G. Wittstock.

Minerogenetic mechanism of Rushan gold deposit, Shandong Province——Evidence of ore-forming fluid and H, O, Sr isotopes

引用

Chinese Science Bulletin 1997年第3期42卷 240-243页

作者： Zhai, jp Hu, K Lu, JJ Department of Earth Sciences Nanjing University Nanjing 210093 China

THE Rushan gold deposit, being of quartz-vein type, is located in biotite monzonitic granite of Kunyushan complex pluton in eastern Shandong, China, and the orebody No. 2 is the largest mono-vein deposits found in China. The gold mineralization can be divided into three stages according to crisscross relations of the various microlodes in the deposit: Ⅰ. pre-ore stage of comb-structured milky-white quartz veins; Ⅱ. main mineralization stage of multi-metal sulphides and siderite-quartz veins; Ⅲ. post-ore stage of mottled cryptocrystalline quartz veins.

Dielectric Behavior of Middle Phase Microemulsion

引用

Chinese Chemical Letters 2000年第8期11卷 739-742页

作者： Lei, jp Li, Y Zhao, KS S China Normal Univ Dept Chem Guangzhou 510631 Peoples R China

Dielectric measurements were performed on middle phase microemulsions composed of sodium dodecylsulfate(SDS), cetyltrimethylammonium bromide(CTAB), n-butanol, n-heptane and brine. Distinct and unique dielectric behavior, with characteristic frequency dependence regularity on the salinity of the microemulsions, was observed in the low-frequency range from 10-10(3)Hz. It can be considered to be an interfacial polarization mechanism.
