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.

这些气 穴通常由具有格外高能量的水蒸气所填充，与混凝土表面的反复接触导致形成凹陷和孔洞，即气蚀。既然高质混凝土也不能抵抗这种劣化，因此最好的补救是通过制造平滑水流来消除气蚀。在所有必须的地方，关键的面上衬以高抗气蚀性的材料。通常，混凝土抗腐蚀和磨损的能力随强度增加而提高。采用硬韧的集料可改善混凝土的抗磨损性。
