At first, we introduce a class of generalized s - r - kkm type mapping in g - convex space, and establish generalized s - r - kkm type nonempty intersection theorem under the noncompact setting of g - convex space. as for application, some new minimax inequalities, saddle point theorem and existence theorem of maximal elements are proved in g - convex spaces ; second, by using the generalized r - kkm mapping and generalized r - kkm theorems in [ 13 ], some new existence theorem of maximal elements, existence theorem of equilibrium point for the abstract generalized vector equilibrium problem and existence theorem of solutions for equilibrium problem with lower and upper bounds are obtained in topological spaces
首先，我們在g -凸空間內引入了廣義s - r - kkm型映像，並在非緊設置下建立了一類新的廣義s - r - kkm型非空交定理，作為應用，證明了g -凸空間內一些新的極大極小不等式、鞍點定理和極大元存在定理；其次，利用文[ 13 ]中引入的廣義r - kkm映像和廣義r - kkm定理，在拓撲空間上得到了一些新的極大元存在定理、抽象廣義矢量平衡問題平衡點的存在定理和有上下界的平衡問題解的存在性定理。In research of controlling system about the switched reluctance motor system ( srd ), there are two prominent problems, one is that it is difficult to set up accurate mathematical model of srm due to serious nonlinearity caused by double - salient structure, the other is that the previous schemes of srd are always equipped with rotor position sensor, which determines the system ' s high speed performance, reliability and cost. as a result, how to detect the position of non - position sensor rotor has become one major direction in the study o f srd
其中較為突出的問題是： 1 ）由於sr電機的雙凸極結構，電機模型具有嚴重的非線性，使得建立sr電機的數學模型非常困難； 2 ）轉子位置傳感器的存在影響了電機控制系統的高速性能、可靠性和成本，所以研究無位置傳感器轉子位置檢測技術（或間接位置檢測技術）是開關磁阻電機系統（ srd ）系統研究的重要課題之一。In chapter 3, together with ding xie - ping and fang min, we proved some new existence theorems of maximal elements and coincidence theorems involving better admissible mappings under noncompact setting of g - convex spaces
在第三章，同丁協平，方敏等合作，在非緊設置下，證明了g -凸空間內涉及較好容許映象的極大元存在定理和重合點定理，並給出應用。After research surface reconstruction with triangular facets, contours of first layer and the last layer are triangulated with layer separation algorithm firstly. and then the least polar - angle criterion is presented for linking two convex contours, and the method is also given in which non - convex contour is transformed to a set of convex contour. with the splitting and integrating algorithm, the single - to - multi - contour reconstruction with triangular facet has been simplified to one - to - one contour
首先採用層析式演算法對起始層和結束層中的輪廓進行三角剖分；然後採用最小極角法實現兩凸輪廓間的三角片重構，並討論了非凸輪廓變換為凸輪廓的方法；最後，使用分裂與合併技術將單輪廓匹配多輪廓的三角片重構簡化為單輪廓之間的三角片重構，最終完成整個骨骼表面的三角片重構。2. reliability of rock slope was done using responding surface method ( rsm ) and monte - carlo method ( mcm ) respectively. reliability index 0 calculated by rsm and mcm are different, which indicates the non - convexity of limit state curved surface in representation of stability of slope
採用響應面法（ rsm ）和monte - carlo法（ mcm ）對邊坡進行了可靠度分析，兩者計算所得的可靠指標存在著一定的差異，這表明：代表邊坡穩定的極限狀態曲面存在著非凸性。At different position and current, the normal force is calculated. this will be used to determine the force harmonics and hence to calculate the vibration resulting from the normal forces. the caculation results are very helpful to the reseach of noise and vibration of doubly salient motors
本文利用vfem對雙凸極電機二維電磁性能進行分析，並對不同轉子位置、不同繞組電流情況下的定轉子徑向磁吸力進行了詳細計算，從而可以進一步研究徑向力所引起的振動響應，這對于雙凸極電機噪聲和振動的研究有非常重要的實際意義。分享友人
