The N gene ORF was then subcloned into pET-30a vector and the recombinant plasmid was transformed into E.coli BL21 (DE3) and induced with IPTG. The protein expression was determined by SDS-PAGE. The expressed protein had a molecular weight of 54.4 Ku that existed as inclusion body. Thin-layer scanning showed that the expression product accounted for 30.5% of the total bacterial proteins. The recombinant protein possessed native biological activity and could react with anti-PEDV hyperimmune serum in Western blot.

Section two:"Phenomenon and reason of technique-orientation in curriculum implementation" studies the phenomenon in real class observation, including people, content, process, evaluation and field; however, subject development history, its impercipient quality and setbacks of setting of regional curriculum all contributes to the reason.

第二部分为课程实施技术取向现象及成因分析。在课程实施的现实情境中，通过对课堂实录的分析，发现从课程实施观念到实施主体、从实施内容到实施过程、从实施结果评定到实施平台等方面都呈现出明显的技术取向。技术取向的存在有源自于计算机课程的学科发展史的影响，有对于其学科性质认识不足的因素，当然，也受到了有关国家禾一I地区相关课程开设现状中某些现象的消极作用。

Comparative study of the properties of both ground and excited states of metal-free indoline dyes for dyesensitized solar cells revealed: as the number of rhodanine rings increases, the energy difference between HOMO and LUMO decreases and there is a red shift in the absorption spectrum with the binding energy increased, and the transition dipole moment decreased; Based on an analysis of cha...

对比研究吲哚染料的基态和激发态性质，揭示了随着绕丹宁环数目的增加，HOMO和LUMO的能量差减少，吸收光谱红移，但是束缚能增加，跃迁偶极矩减少；依据电荷差分密度，电荷和能量从苯乙烯转移到吲哚环和绕丹宁；电子空穴相干性主要表现在吲哚环和绕丹宁环，对于吲哚染料系统，存在一个绕丹宁环的体系的激子数目为30个原子，带有两个绕丹宁环的体系激子数目有40个原子。

According to the research results, the critical behaviors of initial stage are active and friendly behaviors. During the middle stage, the existence of encouragers and followers should improve group development towards high performance. In the final stage, group members shall be able to shift the communication focus from emotionally expressive to instrumentally controlled in order to reach superior effectiveness.

在团队发展初期，必须鼓励成员踊跃主动发言，促进团队结构的有效建立与运作；在团队发展过程中，要适时出现感激、感谢等鼓励性质的对话和追随者的存在，可以促使团队的任务进行更加顺利；在团队发展后期，成员必须要有能力、有共识地将互动沟通的重心转移至任务的执行上，才能达成团队合作高绩效的目标。

On the base of reviewing the development of rural commodity circulation system in weifang, it tries to put forward some measures to improve the government function. It proposes the opinion that rural commodity circulation system is a kind of granted public good. The backward present state of the system has a lot with the neglection valuing of the circulated economy by the government, along with the confused ideas of government function and deviation of government work. And it responsibility to build rural commodity circulation system.

在纵向回顾了潍坊市农村商品流通体系发展情况的基础上，试图对完善政府职能的对策作一些大胆探索，提出了农村商品流通体系具有准公共物品性质的看法，认为农村商品流通体系落后的一个重要原因在于政府对流通经济的地位和作用认识不足，对自身应履行的职能认识不清，并且履职重点也存在偏差。

As our studies showed, silylation of mesoporous molecular sieves with alkoxysilane was an usual method of linking desired organical groups. However, as a result, the a lot of silanol groups still existed on the surface of mosoporous molecular sieves after silylation, which maybe affect the interface property and its catalystic activity. Based on this consideration, a novel method was proposed that a mixture of trichlorosilanes was used to silylate mesoporous molecular sieves, introducing both the further reactive group and hyhrophobic methyl group in one pot.

正如研究表明，通过硅氧烷与介孔分子筛表面的硅羟基反应是常见的键连有机基团的方法，但表面仍会剩余较多的硅羟基，硅羟基的存在会严重影响到介孔分子筛表面性质及催化活性，为此笔者提出采用混合的三氯化硅烷一步硅烷化介孔分子筛，在孔道内同时引入可进一步功能化的氯丙基或氯苄基和疏水性的甲基。

Based on the above experiments, the author studied the mixed metallic pillared and modified montmorillonites. The experimental result indicated that the microporous structure of Fe-Al-PLMs was affected by the changing of interlayer Fe-Al polymer with different Fe/Al ratio. But the presence of Al iron was helpful to incorporate Fe iron into interlayer of montmorillonites.. Introducing Zr helped Al-PLMs getting better larger spacing, thermal stability, surface area and pore volumes. Its successful to apply Zr-Al-PLMs to treat wastewater containing Cr iron. The experiment of modifying Al-PLMs by PVA showed that the order of adding starting materials (Al-pillaring solution, PVA, montmorillonite solution) was related to the property of Al-PLMs. The PVA as precursor was beneficial for Al to go into interlayer of the clay and to form larger basal spacing porous clay. The surface area and pore volumes of Al-PLMs increased mainly because of increasing the external surface area and mesoporous volumes after acid-activating. This conclusion confirmed that the microporous structure of pillaring clay depends upon the interlayer pillar.

实验结果表明：在Al-PLMs中引入Fe离子，不同Fe／Al比制得的Fe-Al-PLMs因层间的Fe-Al聚合离子结构不同而影响其微孔结构，但羟基Al离子的存在有利于Fe离子进入蒙脱石层间；在Al-PLMs中引入Zr离子，有助于其层间距、比表面积、孔体积增大，所得Zr-Al-PLMs应用于含Cr废水处理效果显著；PVA改性后的Al-PLMs其物化性质变化与铝柱化剂、PVA溶液、蒙脱石溶液三者不同添加顺序有关，说明PVA的前撑有利于Al进入蒙脱石层间得到较大层间距的Al-PLMs；经酸化处理得Al-acid-PLMs，其比表面积增大以外表面积为主，孔体积增大以中孔为主，这也证实了柱撑蒙脱石的微孔结构取决于其层间的柱化物。
