The chapter two was focused on the samarium diiodide promoted organic reactions and their applications in organic synthesis, firstly, a new synthesis of highly substituted cyclopentadienes from a,β-alkynone promoted by samarium diiodide was investigated and the highly substituted cyclopentadienes were prepared in moderate to good yields under mild conditions. Secondly, the Michael addition and Michael-aldol tandem reaction of diorganyl diselenides or diorganyl disulfides with α,β-alkynones mediated by samarium diiodide were studied and a series of alkenylsulfides and alkenylselenides were prepared in good yields. Then the highly regioselecfive nucleophilic addition of the allylsamarium bromide to α,β-alkynones were explored. We found that the allylsamarium bromide reacts with α,β-alkynones to afford regiospecificly 1. 2-nucleophilic addition products in good yields under mild condition. At last we studied the coupling reaction of aryl halides promoted by NiCl〓/PPh〓/Sm〓.

The contemporary Chinese city which under the dual pushes of urbanization and globalization is taking a huge change. But with urban scale extends and quick improvement of infrastructure, it brings a series of new city problems. such as the city identity lost, context discontinuousness, disorder space spread, walking environmental depravation and the space meaning weaken etc., as a result, the culture of city which has been formed thousand years ago and it's physical environment are basically eroded .

当代中国城市在全球化与城市化的双重推动下正在发生巨变，伴随着城市规模的急剧扩张，基础设施的迅速改善，出现了一系列新的城市问题，诸如特色的丧失、文脉的断裂、空间的无序、步行环境的恶化，空间意义的弱化等，其结果，千百年来形成的城市文化及其载体正从根本上产生动摇，城市文明面临空前危机。

In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.

在断续切削中，铣削波形可被看作周期函数，将单齿铣削波形看成为脉冲函数，经过傅立叶变换，可以表示为一个按特定的基本频率变动的正弦波形的分量和许多个按基本频率的整数倍而变动的正弦波形的分量叠加而成，讨论所获得的频谱函数，是研究三维复杂槽型铣刀片切削性能的主要环节，以便了解影响单齿铣削波形幅值谱图的各种因素，并从功率谱图的组成情况来考察动态铣削波形的特性，从而进行槽型的设计和优选。

In this study 2mG2-epsps gene was used to be a selection marker gene, and a series of experiments were designed for determining the time of their screening and selection pressure. The results showed that 1 mM glyphosate isopropylamine and 15 days screening can be effectively inhibited non-transgenic maize callus tissue differentiation. So this research work has provided a safe and effective screening system for corn and other monocotyledons crops.
