The flocculus steel balls measured were assembled in luoyang precise bearings company . the results show that the bearing vibration values reached z2 group near 98 % , the bearing vibration values with new technique balls tower above sixty percentile than grind technics . furthermore the bearing vibration values reached z3 group near 83 - 97 % , the bearing vibration values with new technique balls tower above 77 - 90 % than grind technics 然后对加工出的“绒面”钢球在洛阳轴承集团进行了合套测振试验，测振试验结果表明：振动值达到z2组的比例达到98 ，比用研磨工艺制得的钢球合套后测得的振动值数据高出60个百分点；振动值达到z3组的比例高达到83 97 ，比用研磨工艺制得的钢球合套后测得的振动值数据高出77 90个百分点。

By making some assumptions , collision frequency were presented . then the the flocculation kinetics model was established through population balance equation . comparison of experimental data and modeling results indicate that there are the same trend between the two . so the model can predict floes number and size during flocculation of yellow river ' s loess particles without using empirical parameters . the tem and sem were used to obsever floes in the study of floe structure . the flocculation was divided as flocculi , floc and floe aggregate . the floes structure model was established by assumption that particles position in floe accords with tetrahedron . the fractal dimension of model and experimental floes was found to be coincidentso the model can reflect the structure of flocs formed in flocculation of yellow river ' s loess particles by macromolecule flocculant at a certain extent 最后，本文还对絮凝动力学和絮体结构进行了研究，在前人研究的基础上，针对高分子絮凝黄河泥沙，对絮凝过程作了一些符合试验条件的假设，建立了颗粒碰撞频率表达式，应用了颗粒数量平衡方程，从而建立了絮凝过程的动力学生长模型，模型计算结果与试验数据对比表明，二者趋势一致，在没有使用经验参数的情况下基本上能够描述黄河泥沙絮凝过程中絮体数量和尺寸分布的变化过程；对絮体结构的研究中，应用扫描电子显微镜和透射电子显微镜对絮体进行了观察，将絮体分为絮粒、絮团和絮网三个不同的生长阶段，通过假设颗粒结合位置符西安建筑科技大学博士学位论文合正四面体，建立了絮体结构模型，计算得到的模型絮体分形维数基本与试验中的实际絮体相符，在一定程度上能够反映高分子絮凝黄河泥沙生成的絮体结构。

Secondly , the steel balls millstone is used to grind steel ball in ones steel ball factory , and process flocculus the steel balls that possess reticulate veins surface . measure the result as follows : ra ( surface roughness of steel ball ) = 0 . 015 u m , wavmess = 0 . 06 um , sph ( deviation from spherical form ) = 0 . 010 u m , vdwl ( variation of ball lot diameter ) = 0 . 015 u m 然后利用制成的钢球研磨板对钢球进行超精磨削加工，加工出了表面具有网状纹理形貌的“绒面”钢球，利用仪器测量钢球表面的粗糙度值达到了0 . 015 m ，表面波纹度值达到了0 . 006 m ，圆度达到了0 . 010 m ，球批直径变动量小于0 . 015 m 。

Many experiments indicate that flocculus steel balls possessing reticulate veins surface tend to elastic fluid kinetic lubricating layer and improves of the lubricating conditions of bearings . the bearings become quite , and have long life . therefore , in this paper we bring forward a new method to process flocculus steel balls possessing reticulate veins surface 而且许多实验表明：表面呈现网状纹理形貌的“绒面”钢球，有利于钢球和套圈之间的点接触区域形成全膜弹流润滑层，使得轴承的润滑状态得到改善，从而实现轴承减振降噪和提高寿命的目的。

The pathology characteristic that liver fiber changes is collect there are many fibre hyperplasia and deposit inside abbacy and liver flocculus , but have not form the interval inside flocculus , liver cirrhosis has false flocculus to form , central vein area and collect abbacy occurrence interval , the normal structure of liver is destroyed , liver fiber changes further progress to be liver cirrhosis namely 肝纤维化的病理特点为汇管区和肝小叶内有大量纤维组织增生和沉积，但尚未形成小叶内间隔，肝硬化则有假小叶形成，中心静脉区和汇管区出现间隔，肝的正常结构遭到破坏，肝纤维化进一步发展即为肝硬化。
