内陆湖泊相碳酸盐δ~(13)C严重正异常成因模式

对辽河断陷盆地内陆湖泊相下第三系沙三下部地层进行了研究，认为在此地层中碳酸盐δ１３Ｃ严重正异常，并根据其特定的地质背景，进行了成因探讨．结果表明，沉积有机质经成岩演化后生成油气经历了成岩作用、深成作用和变质作用三个阶段．在成岩作用阶段，地质聚合物丢失部分１３Ｃ同位素，在深成作用阶段残余母质中相对富集１３Ｃ，变质阶段生成甲烷的δ１３Ｃ值增大．同时还提出了与有机质分解油气生成有关的孤立封闭盆地δ１３Ｃ异常成因模式．     

ROBUST H∞ CONTROL FOR UNCERTAIN NONLINEAR SYSTEMS

This paper studies the robust H∞ disturbance attenuation with internal stability for uncertain nonlinear control systems. By adding one power integrator technique, this paper designs a explicit smooth robust dynamic feedback law while rejecting the disturbance to any specified degree of accuracy. Further, the example and simulation results show the effectiveness of the proposed schemes.     

Kinetic analysis of self-condensing vinyl polymerization with unequal reactivities

The distribution function of the hyperbranched polymers formed from the self-condensing vinyl polymerization with unequal reactivities was derived and the differential equations for the second moments are established, based on the variable of the conversion of B^＊ groups. The various average degrees of branching can be designed by suitable values of reactivities ratio （r） and the conversion of A group （x）. In order to reach the maximum degree of branching at a specified x, r needed is dependant on the value of x. The higher the x, the less the r needed is for the maximum value of degree of branching. At the end of the reaction, the maximum degree of branching reaches 0.5 with r=2.59.

Probabilistic D-Clustering

We present a new iterative method for probabilistic clustering of data. Given clusters, their centers and the distances of data points from these centers, the probability of cluster membership at any point is assumed inversely proportional to the distance from (the center of) the cluster in question. This assumption is our working principle. The method is a generalization, to several centers, of theWeiszfeld method for solving the Fermat–Weber location problem. At each iteration, the distances (Euclidean, Mahalanobis, etc.) from the cluster centers are computed for all data points, and the centers are updated as convex combinations of these points, with weights determined by the above principle. Computations stop when the centers stop moving.
