Results the nipple surface blood was from central retinal artery,sieve plate former district,sieve plate district and postzone were from short posterior ciliary arteries.sieve plate postzone caliber was the thickest,the surface was the next,sieve plate prezone and sieve plate district were the smallest.conclusion the difference of blood capillary caliber in nipple prompts ischemic lesions occur easily in sieve plate prezone and sieve plate district.

结果 视乳头的血供除表层来自视网膜中央动脉外，其余筛板前区、筛板区和筛板后区主要来自睫状后短动脉。筛板后区口径最粗（7.3±1.4）μm，表层次之（6.2±1.3）μm，筛板前区及筛板区最细（4.9±0.7）μm，（5.0±0.8）μm。结论视乳头各层毛细血管口径不同，提示筛板前区及筛板区容易发生缺血性病变。

Sieve plate postzone caliber was the thickest,the surface was the next,sieve plate prezone and sieve plate district were the smallest.

筛板后区口径最粗（7.3±1.4）μm，表层次之（6.2±1.3）μm，筛板前区及筛板区最细（4.9±0.7）μm，（5.0±0.8）μm。

They get orders from their clients for appli - cants with special skills .

他们奉客户之&命&为之推荐具有特殊技能的求职者，起的是一个&粗筛&的作用。

ZSM two-drum pulse low net work of the screen, pulp pressure from the top of the screen to cut into the screen, the two fall in the middle drum sieve, sieve in the drum inside and outside of the pressure difference and the dual-rotor rotary-wing together, qualified fiber Through the inside and outside the drum screen after screen to the body at the bottom of the pool, and then by the good plasma discharge tube machine, the screen remained in the dark between the flow of rough slurry residue by the rotor and driven together to drum sieve under the tailings from the slot after the Slag discharge pipe.

ZSM双鼓式低脉冲网前筛工作时，纸浆从压力筛的上部切向进入筛体，流到两个筛鼓中间，在筛鼓内外的压力差及双旋翼转子的共同作用下，合格纤维通过内、外筛鼓后汇集到筛体底部，然后经良浆管排出机外，留在筛鼓之间的粗渣受到浆流和旋翼的推动，汇聚到筛鼓下的尾渣槽后从排渣管排出。

If we ask iron ore powder content of the final product particle size less than 100% of negative 80μm, its large particle proportion of mineral particles is relatively small, high frequency sieve sieve wear and tear is not serious under the premise of high-frequency vibrations can be used sieve for grading,Screen carried out under the magnetic separation of ore; sieve of coarse ore, return to re-grinding mill.

如果要求铁精矿粉最终产品粒度负80μm含量低于100%时，其大颗粒的矿粒所占比例比较少，对高频筛的筛片磨损不严重的前提下，可采用高频震动筛进行分级，筛下的中矿进行磁选；筛上的粗矿，回到磨机重磨。
