Based on the study in Lotus japonicus, a model legume plant in Papilionoideae, scientific groups led by Luo Da demonstrated that TCP proteins have been independently recruited as determinants of petal identities along the dorsoventral axis in two distant lineages of flowering plants Antirrhinum majus and Lotus japonicus, suggesting a synapomorphic origin for the mechanisms in the control of floral zygomorphy.

以蝶型花亚科的百脉根为研究对象，罗达等研究组阐明了在豆科与其他物种基因组中调控花对称性发育的分子机制具有共源性，揭示了在高等植物花形进化过程中，不同进化关系的开花植物独立地招募TCP基因，调控了两侧对称花发育过程中背腹轴的发育。

In my opinion,trust is a special agent-principal relation with asymmetric information,an endogenetic factor in finance,and a mechanism for raising the financial efficiency as well.

Based on summary and analysis of various forms of contract between firm and customer, it is found that contract relationship in essence is problem of adverse selection and moral hazard because of information asymmetric and contract items imperfectness.

在总结和分析企业与客户契约关系不同形式的基础上，指出由于信息不对称和契约的不完备性，逆向选择与道德风险问题成为企业与客户契约关系的本质特征。

Some new basic concepts are proposed in this paper, including the approximation space of generalization, rough approximation axiom, disturbance set axiom, classification principle of rough set, principle of nondeterministic even set, principle classification, bit quantum symmetric classification, of concentration, game classification, quantum logic incomparable set, bit space set, protocol relation, rough set function of protocol relation, rough classification algebra, rough simple algebra, etc., and a guess is also proposed.

提出了广义近似空间、粗近似公理、干扰集公理、粗糙集的分类原则、粗选原则、不确定偶集原则、精选原则、对策分类、量子逻辑分类、bit量子对称分类、不可比集、bit空间集、协议关系、粗糙集函数、粗糙分类代数和粗糙单代数等基本概念，并提出了一个猜想；展示了一些新观点；基于协议关系构造了粗糙商代数和粗糙子代数，给出了回避-归并算法及算例。

Sixthly, research on seismic performance of repaired HSC column after hightemperatures The nonlinear whole process analysis method of reinforced concrete is used.Programs of moment-curvature and shear force-displacement of repaired HSCcolumn are developed after exposed to four sides and two symmetrical sides fire.Seismic performance of repaired reinforced HSC column after fire is studied. Byanalyzing the calculating results, the corresponding formulas of characteristicparameters of their skeleton curves of repaired HSC column after fire are proposed,and it is compared with corresponding curve of unfired columns.

火灾后已修复高强混凝土柱的抗震性能研究利用钢筋混凝土非线性全过程分析方法，编制了火灾后(包括四面受火和双面对称受火)已修复高强混凝土柱截面弯矩一曲率关系和剪力—位移关系的计算程序，对火灾后己修复高强混凝土柱的抗震性能进行了研究，通过对计算结果的分析和整理，给出了火灾后已修复高强混凝土柱M-φ及P-△骨架曲线特征参数的回归计算公式，并将上述曲线与未受火柱的相应曲线进行了比较。

Courtesy, reputation and relationship are the main factors causing the dissymmetrical exchanges of presents, and to establish a relationship is the key purpose to obtain some rare social sources or capitals .

人情、面子、关系是礼物不对称交换时都会涉及到的问题，但&建立关系&以期获取某种稀缺性社会资源才是其核心目的。

The tetrasyllabic words have close connection with the language system, and especially the symmetric mechanism and the analogical mechanism is decisive for its origination and development.

四音格现象的存在与语言自身的机制有着密切关系，特别是类推机制、对称机制与四音格词的产生和发展关系更为密切。

On one hand the traditional price theories usually can neither explain supply and demand relation of the market nor the benefits allotment relation between the bargainers because of the incompletion of the market, such as monopoly, exterior, the information dissymmetry etc.

一方面，由于市场本身的不完全性，如垄断、外部性、信息不对称等因素的存在，传统的价格理论往往不能准确地解释市场的供求关系和交易者之间的利益分配关系；另一方面，随着经济的发展和现代信息技术所带来的便利，越来越多的物品(包括有形物品和无形物品)成为可以交易的商品，出现了越来越多的新市场。

But because difference among the predictions of different theoritical models in low z region is small, it is hard to tell us which model is more compatible with the experimental result. Our results from high z binning show a good consistence with the predictions based on z-dependence SU (3) asymmetry, quark-Diquark and pQCD model, which indicate the ud quarks in Λ hyperons provide contributions as well as s quark and the contribution is the function of z.

高z区间分法下归一法和螺旋度平衡法的分析结果显示同z依赖的SU（3）对称模型、夸克--反夸克模型和pQCD模型预言的纵向自旋转移值S〓和z的关系较一致，从而表明Λ超子中u夸克不但对Λ的极化有贡献，而且其贡献和Λ携带的能量份额z有关系。
