tight matrix 中文意思是什麼
tight matrix
解釋
還要注意的一個術語是緊密矩陣-
Abstract : the effect of correction of self - consistent potential on electronic structure in simple cubic nanocrystal particles is calculated by means of the green ' s function method in the tight - binding approximation, taking only the nearest neighbor matrix elements into account. the numerical results show that the electronic energy spectrum is shifted, the chemical potential is not equal to the atomic energy level, the electronic density at each lattice point is changed, and the variation of electronic density at surface lattice point is the largest
文摘:在緊束縛近似下，只計及最近鄰的矩陣元，採用格林函數計算了自洽勢修正對簡立方納米晶體顆粒的電子結構的影響，發現電子能譜發生了移動，化學勢不等於格點原子能級，各格點的電子密度也發生了變化，其中以表面格點的電子密度變化最大。 -
In hard strata with high matrix resistivities, it was considered that the difference between fort - nation resistivity and tight surrounding rock resistivity was caused by fractures except these factors as shaliness, pores, high salinity formation water and the other minerals
在基巖電阻率較高的硬地層中，在去除了泥質、孔隙、高礦化度地層水和其他礦物等影響因素后，地層電阻率與緻密圍巖電阻率的差異就被認為是裂縫因素引起的。 -
It can be known that using pr ( product rule ) method combining with fs ( frame structure ) method can make knowledge expression more convenient and practical. using the " loose & tight coupling " style not only maked for the refresh, expand and administration of knowledges but also can improve the efficiency of system inference. aiming at different inference phases and problems, combining rbr ( rule _ based reasoning ) with fm ( fuzzy matrix ) reasoning by using different inference mechanism is easy to realize solve strategy of the fuzzy inference mechanism
通過該系統的具體開發可知，採用產生式規則和框架系統相結合的方式，可以使領域知識的表達更加方便、實用；應用松緊耦合的方式建立系統知識庫，不僅有利於知識的更新、擴展與管理，而且能提高系統推理的效率；針對制動器設計過程中不同的推理階段和問題，採用不同的推理機制，將rbr / cbr推理與模糊矩陣推理技術相結合，易於實現不精確推理中問題的求解策略；利用人工智慧技術，結合cad / cae手段，是kbe設計方法比較可行的一種實現方式。
