The aim of this study was to develop a novel amphiphilic functional block poly(ε-caprolactone) bearing ketone groups MPEG-b-P(OPD-co-CL. 2-oxepane-1, 5-dione was copolymerized with ε-caprolatone in which methoxy poly (MPEG, Mn=5 000) and stannous octoate were used as initiator and catalyst, respectively. The syntheses were conducted by bulk and solution polymerization. 1H NMR results showed that peak position and splitting of the polymers synthesized through solution polymerization were consistent with theoretical data, demonstrating the products were designed block copolymers. While in the bulk polymerization, polymer peak position was changed due to their high reaction temperature, suggesting their structural variation.

When content of Nicotine increased, protein decreased in leaf and root of toped tobacco. This probably because the content of IAA decreased rapidly and acted as the first signal to transfer to root in toped tobacco, and this made the second signal 桝BA and ZR increased, activated biosynthsis of Nicotine.

打顶以后烟碱含量增加的同时，叶和根中的蛋白氮含量均降低，还原糖含量增加，这可能是由于打顶以后，IAA的迅速降低作为第一信号，沿木质部向下运输到根，引起根部的第二信使一ABA、ZR等含量的增加及GA；含量的减少，激活烟碱合成的三种酶，使总氮中用于合成蛋白质的氮减少，自由氨基酸增加，促进烟碱的合成。

Advances on the development of new oxidation reagents and methodologies and their applications in both target-and diversity-oriented synthesis have been regularly surveyed and constituted one of the most extensively and actively investigated areas of current organic synthesis.1 In this context,a plethora of oxidants,including those small organic molecule-based reagents (such as Dess-Martin periodinane,Swern oxidation,Moffatt oxida- tion,Corey-Kim oxidation,and 三氧化硫/pyridine)and metal-based systems(such as Jones reagent,Collins reagent,pyridinium chlorochromate,pyridinium dichromate,barium permanganate, manganese dioxide,ruthenium tetroxide,silver carbonate,and Oppenauer oxidation),have been identified to be powerful tools promoting conversion of various alcohols into their corresponding aldehyde or ketone products and thus evolved as a most important class of tools in synthetic chemists'arsenal.

And the strengthening mechanism can be described as follows: WC cemented carbides have interlaced short-clubbed grain, and in the bend strength test, the microcrack generates at WC/WC grain boundary, and may be blocked by interlaced fine-clubbed grains during extending, which induce the intergranular pulling-out. Due to the pulling-out mechanism, fracture-extend energy is greatly expended, thus bend strength is increased. The wear mechanism is groove wear and spalling of WC grains.

热机械合金化合成的WC-Co硬质合金比传统方法制备的同类WC合金具有更高的强度，其机理是：热机械合金化合成的WC合金具有交替排列的短棒状组织，在三点弯曲试验中，微裂纹萌生于WC/WC晶界位置，受到交错排列的短棒状晶粒的阻碍，裂纹扩展以短棒状晶粒的拔出方式进行，极大地消耗了裂纹扩展的能量，从而提高了弯曲强度；合成试样的摩擦磨损过程以犁沟磨损和WC颗粒的剥落为主要特征。
