不对称

Acknowledging their work, this paper has made a retrospection and reanalysis to the issues about credit risk based on Information Theory and Economics of Information.

这里，作者主要从信息不对称的观点出发，运用了博弈论的方法分析了信用交易中风险形成的原因及其具体的表现形式。

In addition, we use simple regression model to test size effect.

最后，我们探讨公司规模大小是否会影响买卖单不对称与报酬的关系。

For examples of each, look at the Intrepid and Remora in the ICP. Keep in mind that the amount of asymmetry allowed is faction dependent.

每个例子，看在ICP中的Intrepid和Remora，记住，那些不对称允许从属于阵营。

Apply information asymmetry principle, the reason; that analysed quality of our country produce to drop hands the basic idea with incentive mechanism according to signal, the credit management model that offerred pair of produce producer and interest are revulsive mechanism.

运用信息不对称原理，分析了我国农产品质量下降的原因；根据信号传递和激励机制的基本思想，提出了对农产品生产者的信用治理模型和利益诱导机制。

Now we review on the relationship between the Rho family and cell polarity.

细胞极性化相关的细胞生物学功能包括细胞不对称

In order to meet the demand of precise measurement and applications, the principle of phase retardation with oblique incident angle is expounded, based on the total-reflection phase transformation theory of the phase retardation. By means of Fresnel rhomb, the variation law of the phase retardation for rhomb-type retarder with the incident angle is analyzed. The result indicates that incident angle has obvious influence over the phase retardation.The phase retardation is sensitive to the incident angle, and also has close correlation to incident position of the incident ray, which is asymmetrical to the incident position of the incident ray.

为满足精确应用和测量的需求，从相位延迟的全反射相变理论出发，阐述了斜入射相位延迟原理，以菲涅耳菱体为例，分析了菱体型相位延迟器相位延迟随其入射角变化的规律性，结果表明：当光线非严格准直时，光的入射角对相位延迟量有明显的影响，延迟量不但对入射角变化敏感，而且还与入射光线的入射方位密切相关，呈不对称形式。

The figure of silicon tips etched in this novel etching solution is rocket tips on right rectangular pyramid rather than unsymmetrical eight sided pyramid etched in other etching solution.

更为重要的是该腐蚀液腐蚀的硅尖异于常规的不对称八棱锥，而是一种半锥角很小的"火箭尖"形状，因此可望获得更好的扫描特性和隧道效应。

To an asymmetric synthesis of (1), we applied a type of Roush addition in the first step to introduce the C4 stereocenter, and then the chair substance -122 are readily transformed into the title compound -aphanorphine using the same route as to the racemic target molecular.

aphanorphine分子的不对称合成是在第一步通过对甲氧基苯乙醛（119）发生Roush反应引入手性，得到手性高烯丙醇-122，然后利用与合成外消旋目标分子相同的方法，光学纯化合物-122经一系列转化可得到光学纯中间体化合物139；化合物139发生分子内傅—克反应的过程中，由C4位手性立体特异地控制C1位手性的生成，从而解决-aphanorphine分子中的手性问题。

The auxiliary can be recovered in high yield (81%) only by filtering and recrystallization. Besides, some other aldehydes have been chosen to test the enantioselectivity of N,N\'-dibenzyl tartamide, in comparison with two other allylaborates reagents developed previously by Roush and Brown, respectively. The results show that %e.e. of homoallylic alcohol is superior to that of the former, and approaches the Brown reagent.

产物经S_N2反应得瑞格列萘中间体-甲基烯丙基-2-氯苯基-叠氮甲烷(17)；同时，将筛选出的新型手性配体N-苄基酒石酸二酰胺用于其他几种醛(正丁醛，异戊醛和环己醛)的不对称烯丙基化反应，并与广泛应用的Roush配体(22)和Brown配体(27)相比较，发现其立体选择性优于Roush配体，并接近Brown配体，但明显具有可回收利用的优势。

ABSTRACT: This article studies on the questions that there are non-symmetry and lack of restrict in drive and restraint of the state-owned mine enterprise operator, and it proposes the drive measures and restraint measures (ownership restraint, internal government structure restraint, market restraint, law and system restraint, operator ' s self- restraint and outside supervision restrain) to improve drive and restraint of the state-owned mine enterprise operator.

本文重点探讨了国有矿山企业经营者激励与约束存在的激励约束的不对称及激励约束的双重弱化等问题，并通过对问题产生的原因进行分析，提出了进一步完善国有矿山企业经营者激励与约束机制的激励措施和约束措施（所有权约束，内部治理结构约束，市场约束，法律及制度约束，经营者的自我约束及外部监督约束）。
