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。

The results showed that:(1) some of the past Integrative Activity Course curriculum evaluation criteria ignored the importance of the "teaching activities" and "Instructional Assessment", and lacked reliability and validity data;(2) this new Evaluation Criteria may be used to evaluate textbooks and self-made teaching materials;(3) this Evaluation Criteria contains reliability and validity data;(4) the Epexegesis may help teachers understand the contents of evaluation and is easy to use; and (5) this Evaluation Criteria is useful in teaching teachers to understand the rationale of Integrated Activity Course construction.

It is now a first-rate national center for ophthalmology. Some of the projects rank high internationally, for example, the success of treating 30,000 cases of myopia with LASIK. For the success of the operations, the center introduced sophisticated medical equipment, e.g. the first personalized LASIK. For optimal results, the center used the most sophisticated cornea topographic map, cornea pachymeter, automatic plate shaper and eye ground confocal laser scanning system, making the operations a more sophisticated project. Moreover, as all the doctors have rich clinical experience and expertise, and with painstaking efforts, they acquired great skills and familiarity with the medical equipment, resulting in what is "the man-machine unity".
