When cutting tool roaled of spindle's hole by manipulator or other ways,the pull nail behind of knife hilts is sent to ahead of tension bar of spindle. When receives the clamps signal, the pressure oil is passed over the oil cylinder left cavity of the spindle rear part, the piston to the right migration ,tension bar also to right migration by small dish shape spring function, the stell ball of ahead circumference of the tension bar shrink the distribution diameter by spindle's cone hole's force, holds on the knife hilts and pull nail colsely.

当刀具由机械手或用其他方法装到主轴孔后，其刀柄后部的拉钉便被送到主轴内拉杆的前端，当接到夹紧信号时，将压力油通入主轴尾部的油缸左腔，活塞向右移动，拉杆在碟形弹簧的作用下也向右移动，其前端圆周上的钢球在主轴锥孔的逼迫下收缩分布直径，将刀柄拉钉紧紧拉住。

Rabbit was immunized by the conjugated alginate-BSA (1.0mg/kg) for 40-days routine immunity method; ELISA method was used to examine the titration of anti-alginate serum; The first generation parotid acinar cells were chosen to divided five groups (group A :contrast, group B: BAS, group C: alginate, group D: anti-alginate serum, group E: alginate +anti-alginate serum), We examined the proliferation of each part by MTT method at four times (lh, 6h,12h and 24h); In the meanwhile, The growth and shape of parotid acinar cells were observed under phase contrast microscope and scanning electron microscope.16 of the immunized rabbits by alginate were divided equally into Al and Bl groups, 12 normal rabbits were divided equally into A2 and B2 groups as control groups, Each rabbit was affused by 0.3ml(40fil/ml)alginate though parotid duct once time two days.

将藻酸盐与BSA偶连形成具有较强免疫原性的Alginate-BSA交联物免疫兔，按抗原量1.0mg/kg接种于新西兰白兔皮内，间隔10d加强免疫1次，共加强4次后，利用间接ELISA法检测藻酸盐抗体效价：将原代培养的兔腮腺腺细胞按10~4个/ml接种到96孔板上，置入细胞培养箱继续培养3d，分为5组：A空白对照组、B牛血清白蛋白组、C藻酸盐组、D抗藻酸盐血清组和E抗藻酸盐血清+藻酸盐组，分别加入PBS、牛血清白蛋白、藻酸盐或新鲜抗藻酸盐血清继续培养，分别于1h、6h、12h和24h不同的时间点，取出96孔培养板，采用MTT法检测5组腮腺腺细胞增殖情况

And the pressure drop of liquid-layer is mainly influenced by weir height. With the increasing of weir height, the pressure drop increases. And it is independent of bare tower velocity and plate dimension. The correlation before was corrected as follows:ΔpL＝3911Z This paper analyzed the heat transfer coefficient between the outer wall of heat tubes and cooling water. And it was considered that plate geometries、weir height、bare tower velocity and heat flux density would affect the heat transfer coefficient.

而液层阻力主要受堰高的影响，堰高越高，液层阻力越大，与空塔速度和孔板的几何尺寸无关，对以往的公式进行修正后得到实验关联式如下：ΔpL＝3911Z 本文对加热管外壁与冷却水之间的换热系数进行了分析，认为孔板的几何尺寸、堰高、空塔速度以及热流密度均会影响换热系数。

So from the aspects of economical and social benefit, it has a lot of advantages. On the other hand CFG pile with long screwy drill pipe inner pump pressure is low noisy and without muddy water pollution; The process of drilling will not lead to vibration and has the capacity to penetrate hard rock layer; Also the construction is of high efficiency.

并且长螺旋钻管内泵压成桩工艺具有低噪音，无泥浆污染；成孔制桩时不产生振动；成孔穿透能力强，可穿透硬土层，诸如沙层、圆砾层和粒径不大于60mm的卵石层；施工效率高等优点，所以该技术在全国推广后，得到了广泛的应用，目前已成为应用较为普遍的地基处理技术。
