用Yoon 和Kunii修正的移动床厄贡方程，对宽筛分颗粒在立管中的流动进行了计算，计算结果与试验结果相一致，试验中发现，只要知道宽筛分颗粒的分级速度，便可用Yoon和Kunii修正的厄贡方程计算出宽筛分颗粒的料封能力。

Results The penumatization rate of total or inferior part of middle turbinate correlated positively to the inflammation of anterior ethmoid and maxillary sinuses. Compared with patients with normal frontal sinuses, the vertical diameters of agger nasi cells of patients with frontal sinusitis were larger(11.70±5.50 mm and 8.54±3.67 mm respectivevy, p＜0.01).Compared with patients with normal maxillary sinuses, the Haller's cells of patients with maxillary sinusitis were larger (77.8% and 33.3%,P＜0.05)and the amount of inflammatory Haller's cells of the latter was more abundant than that of the former(91.6±17.8 mm2 and 41.6±12.6 mm2, respectively, P＜0.05). The deviation of uncinate process was one of the factors of maxillary sinusitis .The sizes of ethmoid bullae increased with the soft tissue thickening in anterior ethmoid sinus, the large ethmoid bulla may cause anterior ehmoid sinusitis.

结果 全中甲或中甲下部气化的发生率随前筛、上颌窦内软组织影增厚而升高；有额窦炎组病人的鼻丘气房最大纵向垂径明显大于无额窦炎组(分别为11.7±5.5 mm和8.5±3.7 mm，P＜0.01)；Haller气房在上颌窦炎组和非上颌窦炎组的发生率无显著差异，但前组发生炎症的Haller气房明显多于后组(分别为77.8%和33.3%，P＜0.05)，且前组Haller气房的冠状位截面积明显大于后组(分别为91.6±17.8 mm2和41.6±12.6 mm2，P＜0.05)；钩突角度随上颌窦内软组织增厚而减小；筛泡冠状位截面积随前筛窦内软组织增厚而增大(P＜0.01)。

The precise sieve drum of 15mm, can get rid of the printing ink particle that the tiny impurity and size are greater than 200um in the thick liquid effectively , sticky thing get rid of rate can more than 90%, replacement various kinds of hot newest equipment to disperse equipment that make at present praising highly most both at home and abroad to thick liquid especially.
