In order to analyze the influence of the center air pipe diameter change on the combustion effect, numerical modeling was applied to numerical calculation on the temperature field of such type of boiler,through which temperature field in five different schemes were obtained. In addition, the influence law of change of the diameter of the center air pipe on the temperature field was analyzed. The temperature of the nearly-back wall region takes on a firstly decreasing and then increasing change with the diametrical decrease of the central wind pipe.

为研究改变中心风管直径后的4层燃烧器对炉膛燃烧的影响，采用数值模拟的方法对该型锅炉炉内的温度场进行数值计算，得到5种不同方案下该型锅炉炉内的温度场分布，并分析了中心风管直径的改变对炉内温度场的影响规律，即后墙近壁区温度随着中心风管直径的减小呈现先降低后升高的趋势。

This approach is base on the following idea:under not effect to the deformation of rectangular pipe,to change right angle to obtuse angle which is variant as some regular,make plain-barreled roll pass receive vertical roll shape pipe blank,and then let pipe blank entering into vertical roll pass.With continuous deformation, the difference between diagonal line of rhombus pass will be reduced to zero,finally changed into a square.

该方法的基本思路是：在不影响方矩形管变形的前提下，通过将孔型顶角由直角改为按一定规律变化的钝角，让呈卧菱形状的平辊孔型接纳呈立菱形状的管坯，接着让卧菱形状的管坯进入立菱形状的立辊孔型，随着变形的继续，逐渐缩小菱形孔型对角线之差直至为零，成为正方形。

The results showed that the aphids were either restrained or promoted when they fed on different treatment crops, compared with the control not fed by aphids and the corresponding treatment previously fed by different aphid species. S. avenae restrained the growth of S. graminum (MRGR=0.0974±0.0071) on 98-10-30, but S. graminum promoted the growth of S. avenae (MRGR=0.1614±0.0048) on 98-10-30. Penetrations of aphids promoted the growth of S. avenae on Amigo, while promoted growth of S. graminum on Batis.

结果表明：品种不同，蚜虫在不同处理条件下取食作物时受到的影响也不同，即在品种98-10-30上，通过与前期不接虫的对照及前期接不同麦蚜的相关处理比较，麦长管蚜对后期取食的麦二叉蚜(MRGR=0.0974±0.0071)具有抑制作用，而麦二叉蚜对后期取食的麦长管蚜(MRGR=0.1614±0.0048)却有促进作用；在品种Amigo上，前期麦蚜的危害对麦长管蚜的取食具有促进作用，而在品种Batis上前期危害对麦二叉蚜的取食具有促进作用。

When the molecule C 60 Buckminsterfullerene and its elongated cousins the carbon nanotubes or Buckytubes were discovered, it suddenly became clear that our understanding of the factors governing the bottom-up assembly of atomic and molecular structures involving carbon and other atoms was quite na ve – especially with regard to dynamic construction events at nanometer dimensions.

当发现C60分子及其延伸物碳纳米管或巴基管时，人们突然清楚地了解到有许多因素决定碳原子结构，并且其它材料也是如此，尤其是关于在纳米级尺寸下的情况。
