A solid - state shear compounding technology based on pan - milling ( s3c ) has established , by which the graphite with weakly combined structure are exfoliated and then compounded with pp at nanoscale . the obtained pp / graphite nanocomposites have greatly enhanced electrical and thermal conductivity . their structures and properties were characterized by analysis of particle size and distribution , sem , tem , xrd , the electrical conductivity , the thermal conductivity and heat - decomposition temperature etc . by taking advantages of the layered inorganic fillers with a weak interaction between layers ( e . g 磨盤碾磨剪切力場使pp分子鏈斷裂,相對分子質量減小,石墨的導熱和潤滑性能抑制pp的降解和粉碎,使pp / yep250 (膨脹石墨250倍)復合粉磨盤碾磨固相剪切復合技術及導電導熱pp /石墨納米復合材料的制備與性能體中, pp分子運動活性提高,結晶能力增強,為pp在熔融加工中進一步向己剝離的石墨片層間擴散,形成納米復合結構創造了條件。

4 . the interaction between la3 + and mp - 11 would decrease in the intensity of the soret band and shift the band position , because of the strong coordination action of la3 + with o of the carboxyl group in the heme group and weak interaction of la3 + with o of the amido group in the peptide . the interaction also increases in the non - planarity of the heme group 由于la ~ ( 3 + )與血紅素上羧基氧o配位鍵合作用較強,而與多肽鏈上的酰氨氧o鍵合作用較弱,因此使mp - 11的soret帶吸收值下降,峰位紅移,血紅素環的非平面性增加。

That do not follow the learning rule of human beings , so many problems has appeared in web - based teaching at present , such as weak interaction and non - notable instruction . using artificial intelligent and expert system knowledge , the intelligent courseware generation system based on shared resources pursue a comprehensive solution from the viewpoint of students “ learning . the system aims to help students learning independently and maintaining learning motive force 基于資源共享的智能課件生成系統從學生“學”的角度出發,同時利用人工智能及專家系統等方面的知識,力求尋求一種全面的解決方案,一方面使學生真正做到自主學習,從而維持學習動力,提高學習效果和效率,另一方面為教師提供了制作課件的編輯工具,該工具支持celts標準,教師通過本系統制作的課件可以方便的在其他支持celts標準的平臺下進行無縫移植,將教學資源的重用程度又提高了一層,為教師帶來更大的便利。

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、環糊精以后的第三代主體分子,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。

As to the unbalanced space distribution of the websites , the authors try to analysis and explain the phenomenon , point out weak consciousness of infomationization during websites building , and low information capacity , slow renewal rate , weak interaction as well , then make available suggestions ultimately 針對網站空間分布的不均衡現象,進行了分析解釋,指出了當前網站建設過程中存在信息化意識不強、網站的信息量小、更新速度慢、互動性不強等問題,并提出自己的建議。

The reason is neutrinos only have very weak interaction with matters . they hardly interact with other particles such as electrons , neutrons and protons strongly enough to be detected . this weakness of the force gives the neutrinos the property that matter is almost transparent to them 原因是中微子只參與弱交互作用,亦即是它們和一般粒子如電子中子質子等很難發生關系,因此不易測量得到,物質對中微子來說可算是透明的。

In october 1957 , prof . yang in collaboration with prof . lee tsung dao made significant contributions to the theory of weak interactions by proposing that parity may not be conserved in weak interactions the forces long thought to cause elementary particles to disintegrate 一九五七年十月,他與李政道教授提出弱衰變過程中宇稱不守恒的原理,指真實世界與鏡子里的影像世界不對稱。簡而言之,就是說明了左右不對稱、不等同。

At first stage , the background may be relatively stronger and the collapse is determined on the background , but later the collapse continues by self - gravitation due to the weak interaction of the dark matter 但在最初階段,背景可能相對較強,塌縮主要受背景控制,后來,由于背景的弱相互作用性,塌縮主要由引力系統自身來完成。

It is electrically neutral and has only a small mass . they only take part in weak interactions and gravity . since they interact only very weakly with matters , they could pass through almost anything unimpeded 中微子是基本粒子之一,它不帶電荷,質量極小,只參予弱作用及重力,與任何物質只有極微弱的相互作用,因此穿透力極高。

Under the inspiration of self assembly in biology , chemists are now making use of weak interaction between different moleculars to get well arrayed supramolecular to construct nano - structure 化學家在生物體系自集現象的啟示下,用各種類型的相互作用去創造整齊排列的大分子,用于構筑納米結構的材料。

“ for their decisive contributions to the large project , which led to the discovery of the field particles w and z , communicators of weak interaction 發明粒子束的隨機冷卻法,使質子-反質子束對撞產生w和z粒子的實驗成為可能

At least , in weak interaction , neutrinos may be superluminal particles 至少在弱相互作用中,中微子可能是超光速粒子。

There exist diffrenent weak interactions in the clathrate complexation 得到的籠形包合物中存在不同的弱相互作用。

Weak interaction breaks cp . by cpt theorem , it breaks t as well 弱相互作用中時間反演被破壞的含義是什么呢?

It can be regarded as merely a mathematical quirk of the theory of weak interactions . 這可被看成僅僅是弱相互作用理論的一種數學上的技巧。
