Test and analysis show that, the distribution patterns of the tangent veloctiy fields in the big cone area and the small cone area, which are comprised of para-free vortex and para-forced vortex, are basically identical without a change of the radius of the boundary surface; with the increase of the angle of the small cone, the para-free vortex area decreases and the para-forced vortex area increases, and the emulsifiability of the fluid drips increases with the increase of velocity gradient; the tangent velocity increases with the increase of inlet flow, and the maximum tangent velocities of both the big cone area and the small cone area are 4.94 times of the inlet flow; and the maximum tangent velocity increases with the increase of the split ratio and with the radius of the boundary surface not changed.
试验分析表明,大锥段和小锥段切向速度分布规律基本相同,均由准自由涡和准强制涡构成,分界面半径rm没有变化;随着小锥角θ的增加,准自由涡区缩小,准强制涡区扩大,速度梯度增加会加大液滴的乳化程度;随入口流量增加,切向速度增大,经拟合得出大锥段和小锥段的最大切向速度均为入口流量的4.94倍;分流比加大,分界面半径基本不变,最大切向速度增加。

Material and MethodsRA Rabbit Model group: 15 early RA rabbits of the same weight and variety Control group:10 normal rabbits of the same weight and varietyMethods of making RA rabbit model:elect 15 normal rabbits of the same weight and variety, dissolve Ovalbumin in 0.9% sodium chloride solution, to make the solution of 20mg/ml concengtration, blend the same quantity of complete Freund′s Adjuvant equably ,inject the mixed solution into endermic tissue of the rabbit′s scapular section, making the rabbits allergic, inject 1 ml of the mixed solution to one rabbit every time, inject 1 ml of the mixed solution in 5 different places of the rabbit′s scapular section, inject the rabbit one time every week,inject 3 weeks continuously,it turned out to be that the rabbits will be allergic, inject Ovalbumin blent with the 0.9% sodium chloride solution into the knee joint cavity of the rabbits in the fourth week, 5 mg Ovalbumin every knee joint cavity,two knees of every rabbit of the 15 rabbits are both injected,the arthrosis diameter and the exterior temperature of the knees will be added obviously in 24 hours,and they will drop gradually,at the time of the 14th or 21th day, the arthrosis diameter and the exterior temperature of the knees will get to the balance time,the incidence rate of RA is 100%.after the RA model succeeds,it is the early time of RA from the first week to the fourth week,after the fourth week,it is the late time of RA, the cartilage of the femoral condyle and the subchondral bone cortices will be changed unrecoverily.
资料与方法RA模型组:早期RA家兔模型15只,品种及体重接近。对照组:正常家兔10只,品种及体重接近。RA家兔模型制作方法:选取15只成年家兔,体重、品种接近,将卵蛋白溶解于生理盐水,配成浓度为20mg/ml的溶液,与等量完全弗氏佐剂混匀,注入家兔肩胛区皮下致敏,每只家兔每次注射1ml,于肩胛区5个不同区域注射,每周一次,连续注射3周而致敏,第4周向膝关节腔注射卵蛋白生理盐水溶液,每只关节腔注射5mg卵蛋白,15只家兔膝关节全部注射,24h内此关节直径和表面温度大幅度上升,以后缓慢下降,至14~21d达到平台期,发病率达100%。造模成功后第1~4周为早期改变,第4周以后出现不可逆的关节软骨及骨破坏。采用高频超声对RA模型组与对照组的膝关节髌上囊液体厚度、滑膜及股骨髁软骨厚度及软骨下骨皮质的回声情况进行对比观察。结果RA组模型组膝关节髌上囊积液及滑膜的厚度明显厚于对照组,其股骨髁软骨的厚度与对照组相比无明显差异,其软骨下骨皮质与对照组相比无明显改变。
