This paper analyses the working principle of CFG pile composite foundation and construction technology, especially focuses on the comparison with other piles in construction skills. Aiming at the geological characteristic of haugh in Zhengzhou, the theory of seepage deformation and the pore expanding were applied in the research work of CFG pile impacting the surrounding environment. Then the controlling solution was listed in the paper.

为此，通过对CFG桩复合地基工作机理、施工方法的分析研究，特别是CFG桩与其它桩型施工方法的对比分析(如CFG桩与沉管灌注桩、CFG桩与钻孔灌注桩比较分析)，针对泛滥平原工程地质的特点，运用渗透变形原理、小孔扩张理论等较为深入地研究了CFG桩环境效应，并提出了相应的控制措施，主要研究成果归纳如下：(1)本文提出了针对泛滥平原工程地质单元地区"二元"结构地层，CFG桩长螺旋钻管内泵压施工对周围环境的扰动机理。

Helicoid rotates in the pipe- shaped trough or U-shaped trough with internal anti-abrasion protective lining and produces pushing force to push material to move forward, so that the goal of conveyance can be reached.

螺旋休在有内部防磨损保护衬套的管型槽或u型槽十旋转而产生推动作用，使物料向前运动，从而达到输送门的。

The hardware included helicon wave antenna and focusing system.

其中硬件系统主要包括：螺旋波天线和辉光聚焦系统的设计；PCL-818HG数据采集卡输出的+5V稳定信号，经过分压电阻和三极管后，作为数控器的外部启动/停止信号，控制步进电机带动光谱仪转动；另外，为了减小光电倍增管的噪声，单独为其提供了稳定的高压直流电源。

ABSTRACT In this article the manufacturing method and characteristics of the double wall brazed tube with inner helix groove are given.

We got that,the charged particles be binded in this field,and canonly move along the magnetic line of force as spiral motion and the positive charges andnegative charges moved in opposite direction which be fromed the big molecular groups thatbe hardly absorption,by means of incrustation preventing.

讨论了轴对称非均匀磁场对带电粒子的作用，分析了"磁约束"对防垢、除垢的微观机理，指出满足磁约束理论的轴对称非均匀磁场的防垢，除垢效果好的原因，正是由于在这种磁场中，带电粒子的运动被约束在一定磁面上的某一磁感应线附近做以该磁感应线为中心的螺旋运动，且正、负离子的回旋方向相反，从而形成内部相互作用较弱的大分子簇团不易吸附在管壁上，达到防垢目的；磁化水的渗透压较大，可起到除垢效果。

Results All cases could display an enhanced mass as local filling defect at the site of the duodenal Vater′s ampulla during arterial and portal phase scanning, the tumors ranged in size from 1 cm to 5 cm with mean of 2.3 cm, all were accompanied with dilated intrahepatic and common bile duct, enlarged gallbladder and dilated pancreatic duct, except one case which had marked atrophy of the pancreatic body and tail.

结果螺旋CT动脉和门脉期增强扫描，15例均清晰显示十二指肠乳头部局限性强化的充盈缺损块影，肿瘤瘤径为1～5 cm，平均2.3 cm。所有病例均可见肝内胆管扩张、胆囊增大、胆总管扩张和胰腺管的扩张，仅有1例伴胰体尾部的明显萎缩。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
