共解析了三種化合物的單晶結構,並且從結構分析發現隨著陽離子上的取代基的加長,陽離子的平面性下降第三章主要對這一系列化合物的光學性質作了系統研究。At the same time, on the basis of above results, the stability problem of the polarization of particle self - spin is discussed in irregular magnetic field of accelerator. the discovery that the low degree polarization system is very sensitive to the irregular magnetic field while the high degree polarization system is very stable is found. the irregular fluctuation of the vertical ponderance is complementary to that of the horizontal ponderance due to the self - spin conservation
同時,在此基礎上,利用su ( 2 )代數動力學方程研究了加速器中帶自旋離子的極化對磁場的含時無規擾動的穩定性問題,發現:低度極化的系統對磁場無規擾動十分敏感,而高度極化的系統對磁場無規擾動十分穩定;自旋守恆導致自旋的縱向分量的無規漲落和橫向分量的無規漲落存在著互補性。As for instruction practice, in the perspective of postmodernism, it will keep open to all the people ' s real life and potential creativity. it will make itself much closer to reality but away from systemization and symbolization by putting into serious consideration interference factors called noise by modern instruction such as unrelated factors of problems, accidental events in class and students " affection and experience and so on
就教學實踐而言,在後現代思想視野下,它將呈現出一種向「所有人的真實生活與潛在創意」開放的姿態,它通過讓那些被現代教學視為「噪聲」的干擾因子,如問題中的無關條件、課堂上的突發事件、學生的感情體驗等登堂入室,使自身更貼近現實生活而遠離制度化和符號化。The paper puts forward the clustering algorithm includes : clustering based on grid and iterative, enhanced clustering algorithm base on density and k - medoids, enhanced k - means algorithm ( optimize chooseing consult _ points in iterative process ), enhanced clustering algorithm base on distance. they can overcome many limitations ( some traditional algorithms terminate in local optimization. many results of cluster are roundness, too many times in partition iterative process ), which are related to the static architecture of traditional model
在傳統聚類演算法的基礎上,結合我們科學數據挖掘的應用對象?分子動力學數據,提出了迭代網格聚類演算法, k -平均和基於密度結合的聚類演算法,迭代過程中優化選擇中心點的k -平均方法,以及改進型的基於距離的聚類演算法等模式識別方法,能夠解決傳統演算法帶來的諸多問題(比如一些傳統的聚類演算法常常收斂于局部最優,發現都模式都趨近於球形,劃分方法中迭代次數過多帶來的效率問題) 。It has draw more and more attention of scientists with the prospection use in matieral chemistry, coordination chemistry and biochemistry. by using resorcinarene as framework of supramolecular construction, we studied the single crystal structure by evaporation of acetone with the exist of a little water molecular and found that under several weak interactions, a novel nano - one - dimention supramolecular tube was abtained
杯芳烴是繼冠醚、環糊精以後的第三代主體分子,它兼有絡合陽離子與中性小分子的功能,在材料化學、配位化學、生物化學等領域表現出潛在的應用前景與研究價值,因此吸引了越來越多的化學工作者的注意。Originally from green concrete and concreting in minus - temperature, the critical strength of frozen injury of minus - temperature calcium - enriched fly ash concrete and the rule of strength development are studied in this paper. through the test of resistance of freezing - thawing cycles and chloride diffusivity, the influence of curing system and calcium - enriched fly ash on the performance of concrete are studied ; and through the modern methods ( xrd, sem, and so on ), the hydration products, pore structures and microstructure are studied
