By using properties of quasi-regular semigroups and left central idempotents, some statements are proved. Let S be a quasi-right semigroup, then (1) S is a quasi-completely regular semigroup;(2) RegS is a completely regular semigroup;(3) R(superscript *) is the smallest semilattice congruence on S;(4) Each R-class T(subscript α) on RegS is a right group;(5) T(subscript α)G(subscript α)×E(subscript α), where G(subscript α) is a group, E(subscript α) is a right zero semigroup.

利用拟正则半群和左中心幂等元的性质，证明了S为拟右半群时，(1) S为拟完全正则半群；(2) RegS为完全正则半群；(3) R为S上的最小半格同余；(4) RegS上的每个R-类T为右群；(5) TG×E，其中G为群，E为右零半群。

Organozinc reagents can react with a variety of α,β-acetylenic ketones and aldehydes in the absence of any catalyst. The one-pot reaction affords β-branched Baylis-Hillman type adducts, the multifunctionalized alkenes, in excellent yields with high stereoselectivity.

这种顺式亲核加成反应的发生是由于该类有机锌试剂既具有较强的亲核性，又具有Lewis酸的特性，使有机锌中R基团从同位进攻中心碳原子而形成新的碳碳键。

In this paper,the authors summarize studies on the origin of Boehmeria and advances in the study of genetic relationships of Boehmeria using morphological, chromosomal, isozyme and DNA marker techniques. The authors also put forward the future direction.

本文概述了苎麻属植物的起源中心以及植物形态学、染色体、同工酶与DNA分子标记等研究方法在苎麻属植物亲缘关系的研究进展，并对今后开展这方面研究提出了几个重要问题。

Abnormal centrosome, as chrosomal instability, is a widespread characteristic cancer cells.

中心体异常同染色体不稳定性一样是肿瘤细胞的一个普遍特征，并且可出现在肿瘤发生的早期阶段。

Customer relationship management, CRM for short with English. It is a management viewpoint and it considers customer is central. It is a result of coalescent of corporation culture and operation system.

客户关系管理，英文简称CRM，就是在企业文化同业务系统结合的同时，形成的以客户为中心的经营理念。

We calculate the coseismic and postseismic deformation using FEM. We use the GPS data of crust deformation as the constraints and obtain different Fortran programs of different questions by FEPG, and study the role of physical characters in regional geodynamic behavior.

以GPS观测所得地表形变做约束，用FEPG实现了强地震引起的同震和震后形变有限元数值模拟，并掘此分析了以介质物性为中心的强地震区域的环境动力学特征。

Observation of radar and intensive surface wind of 0505 typhoon Haitang is used to analyze the relationship between radar reflectivity and observed precipitation and the relationship between mesoscale surface stream field and heavy rainfall. The analysis shows that when the Doppler radar reflectivity reaches 50 dbz, it has a good correspondence to the heavy one hour precipitation. Besides, heavy precipitation is also related to the mesoscale cyclonical current and confluent currents, it occurs near the mesoscale cyclonical or confluent current appearing at the same time.

利用严重影响浙江东南地区的2005年05号台风的雷达和地面加密风场资料，分析对比台风中尺度暴雨过程中雷达回波与实况降水、中尺度地面流场与暴雨之间的关系，结果得到：多普勒雷达近地面强回波带或中心往往达到50 dbz时，与一小时的强降水区有很好的对应关系，暴雨中心区也与地面加密的中尺度流场中出现的中尺度气旋性环流和汇合气流有关，强暴雨区落在同时刻中尺度涡旋或汇合线附近。

So to analyze in the aspect of description, it is useful to delouse the fount how inarticulateness comes into being; Based on the economic relationship and from the viewpoint of the pursuit of aim, the object of studying, the original creation of aesthetics, as well as the articulate knowledge and inarticulate knowledge, Polanyi distinguished the acquisitive way of science and technology. The development model of personal Knowledge can be generalized as the enthusiasm of seeking knowledge; Polanyi revealed how personal factors of mathematician cut across logical chasm, and gained mathematics findings in math" s activities. Thus he proved mathematics was also activity-needed techniques as natural science; Last evaluating the theory of "Personal Knowledge systematically, it can reveal its realistic significance and limitation.

波兰尼把认知结构区分为可言传知识与不可言传知识，与20世纪以来西方哲学的中心课题转向语言学的研究一致，所以从言述的角度出发，有助于了解不可言传性如何形成的根源；波兰尼以经济关系为立足点，从科学与技术的目的追求、研究对象、美的原创性，以及从可言传知识与默会知识的角度对两者的获取途径做了区分；其个人知识发展模式可以概括为：求知热情→启发性热情→说服性热情……；波兰尼揭示出数学家的个人因素是如何在数学活动中跨越逻辑鸿沟，取得数学发现的，从而证明数学同自然科学一样，也是一项需要技能的活动；最后对&个人知识&理论作一系统的评价，揭示&个人知识&理论的现实意义和局限性。

Within the Central European part of Russia's ethnic turn of the century the rise of the core area of .15 in Moscow as the center to form a centralized state in Moscow Duchy .1547 expansionist years later, vast tracts of land in neighboring countries Gezhan .1917 11 7 On the establishment of the Russian Soviet Federative Socialist Republic, in December 1922 with Ukraine, Belarus, South Caucasus Federation composed of the USSR (Union of Soviet Socialist Republics). 1924 -1940, Lithuania and other accession, a total of 15 former republics.

境内欧洲部分中部是俄罗斯民族兴起的核心地区。15世纪末形成以莫斯科为中心的中央集权国家莫斯科公国。1547年后推行扩张主义，割占了邻国大片土地。1917年11月7日成立俄罗斯苏维埃联邦社会主义共和国，1922年12月同乌克兰、白俄罗斯、南高加索联邦等组成苏联（苏维埃社会主义共和国联盟）。1924年—1940年，立陶宛等加入，共15个加盟共和国。

Ten patients with homonymous hemianopia received a 30-diopter fresnel plastic paste-on prism on their glasses. The prism was pasted base out toward the side of their hemianopia and on one lens only. A small 1 to 2 mm portion was cut out of the center to prevent diplopia.

利用一30稜镜度之Fresnel稜镜贴在同侧性半盲病人的眼镜上，稜镜的基底部置於半盲侧，只须贴一眼，譬如右侧半盲病人贴右眼的颞半侧，中心部份要剪掉1至2毫米，以避免复视。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
