选择性的

20Th Century Fox declined comment, but in a news release announcing 7-Eleven's promotion with the movie, Lisa Licht, the studio's executive vp global marketing partnerships, said the promotional strategy was to "partner with companies that would execute programs that have never been done before."A source close to the movie's promotions said that the studio and the filmmakers were "extraordinarily selective and specific in terms of the creative content" for tie-ins.

二十世纪福克斯拒绝评论，但在一份新闻稿公布 7-11的推广与影片中，丽莎 licht ，工作室的执行 VP的全球营销夥伴说的宣传策略是"合作夥伴的公司将执行的节目，从来没有做过，"一位接近电影的促销说制片厂和制片人"非常有选择性的，具体在从创作内容"，为配合行窃。

A Source, inhibitors, and determinants of change. The system of biological replication does not work with ideal precision; random variations occur which , over the long run, would have a totally self-cancelling and , therefore, leveling and difference-eroding effect unless some factors of bias were operating selectively upon this bounty of variations. This is true of life, in general, and of all aspects of organisms.

a 改变的来源、限制、决定因素：生物的复制系统并不是百分之百精确的，随机发生的变异，最后都会全部自我销毁，除非这些混乱的因素能被选择性的运作与接受，这些击毁和磨损语言的变异才具有影响力，普遍来说，这就是真实的生命，就是生物体的所有面貌。

The mass transter can be enhanced ,when we introduce sulfuric acid and cuprous oxide into this system.The model is formed to describe the transference of the martial between the four phases: gas-liquid-liquid-gas, which can explain some problems. We analyze the dead of the catalyst, and make a conclusion that the surface of the catalyst is covered with some compounds such as bluestone, which lessen the activity points of the catalyst and debase the activity.

在SO_4~(2-)／ZrO_2-La_2O_3催化的反应系统中加入稀硫酸和氧化亚铜促进了异丁烯和一氧化碳的传质、使反应得以快速，高选择性的进行，异丁烯的转化率达95％以上，特戊酸的收率达47％；讨论了g-l-l-s传质过程；对催化剂作了失活分析，催化剂失活的原因是因为反应后的催化剂表面覆盖了一层硫酸盐，使催化剂的活性中心数减少，活性降低。

"Apraclonidine, a selective alpha-2-agonist, was developed to lower intraocular pressure and minimize the systemic side effects associated with the use of its parent drug, clonidine," write Patrick Watts, MBBS, MS, from the University Hospital of Wales in Cardiff, United Kingdom, and colleagues."An investigation of the site of action of apraclonidine incidentally uncovered a reversal of anisocoria in patients with absent sympathetic innervation of one pupil due to its alpha-1-effect on a pupil with denervation supersensitivity.... The easy availability of apraclonidine, its mild alpha-1-agonist activity, and its hitherto benign safety profile has encouraged its use as a first-line drug in the diagnosis of oculosympathetic paralysis."

英国加地夫市威尔斯大学附设医院的外科学硕士Patrick Watts及研究同仁指出，Apraclonidine是一种选择性的α-2-拮抗剂，是用来降低眼内压，并减少其母系药物降保适使用上的相关全身性副作用；在一项针对apraclonidine作用位置的研究中，因其单侧瞳孔神经切除之α-1-效应，而附带提出单侧瞳孔无交感神经支配患者之瞳孔大小不等为可逆转，apraclonidine之高可利用率，其轻微的α-1-拮抗活性，以及迄今良好的用药安全档案，更强化其作为视交感神经瘫痪诊断第一线药物的使用率。

What\'s more, different intervals of UV have their own characters in influencing DNA: the damage to some bases by UVA may be more serious than that by UVB, and UVB did more severe damage to some deoxyribose than UVA; however, as far as the pyrimidine bases are concerned, the damage by UVB is by far more serious than that by UVA. These results may indicate that there are preferential damaging sites on DNA molecules caused by UVA and UVB irradiation. Moreover, with UVA or UVB irradiation for a long time, the photoreactivation of DNA occurred. The serious damage to deoxyribose and bases by UVB and UVC may confirm the conformation of cyclobutane pyrimidine dimers and (6-4) photoproducts.

而不同波段紫外辐射对DNA的损伤各具特点并且差异明显，UVA对一些碱基的损伤比UVB要严重，而UVB在对脱氧核糖和磷酸盐的损伤上又比UVA要严厉，但就嘧啶碱基来说，UVB对它的损伤远大于UVA，这似乎表明了不同的紫外波段对生物大分子DNA的损伤是有选择性的。

On the other hand, a method for the synthesis of-vinyl chalcogenides by the coupling of vinyl bromides with thiols or diphenyl diselenide using copper salts as catalysts in ionic liquids based on amino acids also has been described. The ionic liquids play multiple roles in the reaction: they act as solvent, base, and excellent promoter for the copper-catalyzed coupling reactions.

在新型的氨基酸负离子的离子液体中，开发了一个亚铜盐催化的Z-型溴代烯烃与硫族元素的交叉偶联反应，为立体选择性的制备Z-型烯基硫醚或烯基硒醚类化合物提供了一个新的方法；在此反应体系中，离子液体不仅起到了反应溶剂的作用，而且还起到了金属催化剂的配体和中和反应副产物的碱的作用。

Other methyl nucleophiles includingMeMgBr, MeCeCl2, MeTiCl3, Me3Al, Me3ZnMgCl, MeMnClwere tried, but in all these cases no detectable amount of exo-C8-methylated product was obtained. Although protecting C3-carbonyl as 1,3-dioxolanes could be achieved, the serious enolization of C8-carbonyl was still problematic. Converting C9-furan ring to α,β-butenolide did depress the enolization, but desired C8-methylation was completely replaced by migration of the double bond of the butenolide.

在本论文的早期阶段，主要着眼于解决二环[3.2.1]-C8-羰基加成甲基所遇到的C9-呋喃环差向异构化和C3与C8两个羰基之间化学选择性的问题：通过引入不同金属降低甲基试剂的碱性并没有取得甲基化的成功；通过不同的方法将C3-羰基掩蔽，但是C8-羰基的烯醇化依然无法抑制；虽然通过将呋喃环转化为α，β-不饱和-γ-丁内酯可以抑制烯醇化，但内酯环上的双键迁移又成了新的竞争反应。

Facing this situation, according to the hortation and assit system for planned parenthood being taking into effect in the rural area of our country, this thesis analyzes the deficiency of the present rural social pension system and discusses countermeasures and approaches about how to combine these two systems and improve the rural social pension system based on the analysis of necessity and feasibility of transition from"selective"hortation and assit system to"prevalent"rural social pension system. This thesis can be separated into five parts.

针对这种现状，本文从分析我国农村社会养老保险制度存在的问题与不足入手，结合当前我国在农村推行的农村部分计划生育家庭奖励扶助养老制度，从理论和现实的角度分析将奖励扶助养老制度与农村社会养老保险制度相结合建立农村计划生育家庭养老保险制度，以及将这种&选择性&的社会养老保险制度向&普惠性&的农村社会养老保险制度过渡的必要性和可行性，在此基础上进一步探讨了如何将两种制度有效结合，以及改进和完善我国农村社会养老保险制度的对策和途径。

Substituted-2-aminobenthiazoles were dissolved in a mixture of acetic acid,phosphoric acid and propionic acid, and diazotized by nitrosylsulphuric acid, then coupled with m-dimethylaminobenzoicacid to form 6-R-BTAMB in good yield.

我们在2-氨基苯并噻唑的6-位引入了不同的取代基R，合成了6种新试剂，2-I2'-(6'-R-苯并噻唑)偶氮-5-二甲氨基苯甲酸(6-R-BTAMB，R=〓，〓，Cl，Br，〓，〓，)，并研究了6-R-BTAMB与Fe、Co、Ni、Cu和Pd的络合显色反应的光度性能及不同R基团对试剂灵敏度及选择性的影响将6-〓-BTAMB应用于测定铝合金，电镀废液中的铜，人体毛发和矿泉水中铁的含量均取得了满意的结果。

一长串的故事包括对方故意前后不一，执行规定不透明，肆无忌惮的偷窃知识产权，政府通过工会和中共基层组织渗透西方大公司，利用暗算的产品标准和检测公然阻止产品进入市场，政治化的法院和政府机构几乎永远都偏向中国大陆的企业，别出心裁、选择性的实施世贸组织的规定等等，不一而足。
