Many empirical investigations have validated that the " day - of - week effect " is an ubiquitous phenomena in many developed countries " securities business and in some burgeoning stock market . but the methods investigations have used were so different that one conclusion can not be horizontally compared with the other conclusion . furthermore , some method model themselves were possible ill - suited to securities data 许多实证研究证实， “周内效应” ( day - of - theweekeffect )是国外许多发达国家证券市场与某些新兴的股票市场普遍存在的一种现象，但所使用的分析方法各异，难以使人将结论进行横向比较，更为可能的是，有些方法模型本身可能对证券数据是不合适的，建立合理的统计检验“周内效应”方法是本文仔细研究的问题。
Islamic law is a phenomenon so different from all other forms of law ? ? notwithstanding , of course , a considerable and inevitable number of coincidences with one or the other of them as far as subject matter and positive enactment are concerned ? ? that its study is indispensable in order to appreciate adequately the full range of possible legal phenomena 伊斯兰法是一种现象，它如此不同于所有其它法律形式? ?当然，虽然存在大量的而且不可避免的巧合相同内容，对于其它法律，当考虑到主题内容和有正面性的法规时候? ?以致于对它进行研究是不可缺少的，为了充分理解有可能的法律现象的全部范围。
Witness unwilling to appear in court has so many reasons such as reasons in the culture respect , in proceedings value and legal systems regard and the social , personal reasons . witness not appearing in court is a phenomenon resulting from chinese specially cultural background and legal systems , witness not appearing in court has been a grave problem in the process of our country ' s judicial system reform 证人不愿出庭作证既有文化心理上的原因，也有诉讼价值层面和制度层面的原因，有社会原因也有证人自身的原因，证人出庭难是在中国独特文化背景和司法制度下衍生出来的一种现象。
A lunar eclipse is a natural phenomenon . it occurs when the earth falls in direct alignment with the sun and the moon , resulting in the moon s passing into the shadow of the earth . during a lunar eclipse , the sun and the moon should travel to the opposite side in the sky about 180 apart from each other 月食是自然界的一种现象，当太阳地球月球三者恰好或几乎在同一条直线上地球在太阳和月球之间，太阳照射到月球的光线便会部份或完全地被地球掩盖，产生月食。
Having a glance at our daily life , you may easily find that there exists such a phenomenon that most of our contracts are manipulated by one party without mutual agreement . contracts in insurance , banking , public houses leasing , water and electricity supply , vehicle and aircraft transportation , postal and telecommunication service domain are usually concluded not through offer - accept procedure but through the procedure that one party present all the conditions , the other party ( consumer ) can only generally accept or otherwise . there is no room for bargain . this kind of contract is called form contract 只要留心就会发现，在我们生活中存在这样一种现象，即我们所签订的合同中有相当一部分未经双方协商一致即由对方一手操纵，例如与日常生活关系密切的保险、银行、公房租赁、水电供应、车船飞机运送、邮政电讯服务等合同，都没有经过通常的要约? ?承诺的签约过程，而是由一方(通常是由卖方或提供服务的一方)提出合同的全部条款，对方(消费者)只能概括地全部接受或全部不接受，没有讨价还价的余地。
It is one of mechanisms of plastic distortion , at the same time it is also the beginning of microcosmic damage and rupture before the macroscopical destroying of materials , it representatives a mid - state between materials " macroscopical rupture and bend , it is considered a premonitory that the rupture of polymer material , which get common attention by scholar inside and outside nation . therefore , the research for engineering polymer in mechanic action of non - linearity destroy such as distortion , destroy and depe nd on time and temperature is valuable in theoretic research and actual application , which offer the important theoretic gist for changing complex material ' s capability and actualize polymer ' s perfect application with high quality of capability in engineering 同时，银纹化和银纹损伤是高聚物特有的一种现象，细观层次的银纹引发、生长和断裂在聚合物损伤断裂的整个过程中起着承前启后的作用，它是沟通宏、微观变形机制的桥梁，是材料塑性变形的机制之一，同时又是材料宏观破坏以前微观上损伤、破坏的开始，它代表材料微观断裂和屈服之间的一个中间状态，可以看作是聚合物材料宏观断裂的先兆，受到国内外学者们的广泛关注。因此，开展工程聚合物变形、破坏以及时间相依和温度依赖性等非线性力学行为研究，探讨聚合物破坏过程中的非线性力学行为，为聚合物及其复合材料的改性、实现聚合物的工程化与高性能化提供重要的理论依据，具有重要的理论研究意义和实际应用价值。
Through analyzing the phenomenon of the pseudo complex value in the block - decoupling method , the pseudo complex value is considered as the result of eigenvalue variation because of the system being decoupled forcedly , but this phenomenon has no effect on the result of the small signal stability 对模糊分块解耦法可能出现的伪复根现象进行分析，认为伪复根是将原本存在机电耦合的子系统强行解耦导致特征值“变异”的一种现象，一般不会影响小扰动稳定分析的结果。
The conglomeration a group of interrelated enterprises and institutions in a region forms enterprises cluster , which is often to show high flexibility in production and speed in innovation , and to promote the economic competitiveness and development of the region . this phenomenon has attracted wide attention of researchers at home and abroad 一组相互联系的公司和机构在一定地理上的集中形成企业集群，并且往往表现出较高的生产灵活性和快速的创新能力，促使区域整体获得竞争优势，带动区域经济的发展，这样一种现象引起了国内外学者的广泛关注。
