8.This paper represent a little Rough Set theory, and its peculiar rule extraction mechanism,manifest that on the data mining it can make the best use of Rough Set theory, for example,we can extract knowledge or simplify experience by use of its reduction technology. Rough Set theory also have much sense to expert system and knowledge store.
9.The sun sets on some retired meadow, where no house is visible, with all the glory and splendor that it lavishes on cities, and, perchance, as it has never set before, ----where there is but a solitary marsh-hawk to have his wings glided by it, or only a musquash looks out from his cabin, and there is some little black-veined brook in the midst of the marsh, just beginning to meander, winding slowly round a decaying stump.
10.Abstract: Based on spline function method,the spline finite element formulation for the contact-impact problems is proposed.In order to get the formulation,the B3 spline function is used to distribute the contact problem,and numerical examples are analyzed to show the effectiveness of the method.Because the spline function has double characteristics including analytical and numerical,and good continuity and high correctness,a little unknown number and high efficiency,the spline functions are used to set the displacement of the bar,and the whole structure equations are constructed directly.It is convenient to analyze dynamic response of the structure by using the method.
