这些趋势的不相关性表明穿孔性和非穿孔性阑尾炎可能有着不同的病理生理机制，而抗生素治疗的非手术治疗可能适于初始非穿孔性病例。

The calculating results are compared with the test data in available literatures and FEM results. The research results show that the plastic hinge model is precise and correct, which can satisfy with the actual engineering demands. The collapse pressure of perforated liner casing decreases with phrase angle, initial ovalization and diameter-thickness ratio increasing, and increases with the yield stress. The phrase angle and initial ovalization have greatly influence on the collapse pressure. The collapse pressure of perforated liner casing is slightly changed with the diameter and density of perforation when the diameter and density are smaller than 12mm and 120 shots per meter, respectively.

计算结果表明：筛管抗挤强度的塑性铰模型具有很高的计算精度和准确度，可以满足工程实际需要；筛管抗挤强度随着射孔相位角、径厚比和初始椭圆度的增加而降低，随着屈服强度的增加而增加，相位角和椭圆度对筛管抗挤强度影响比较显著；在射孔直径小于12 mm、射孔密度小于120 孔/ m 时，筛管抗挤强度随射孔直径和射孔密度增加变化不明显。

The screen at least partially circumscribes the non-perforated section of the base pipe, and the ribs extend longitudinally in an annular space between the screen and the non-perforated section.

筛管至少部分地围绕基管的未穿孔部分，且肋在筛管与未穿孔部分之间的环形空间内纵向延伸。筛管组件的柔性部件卷绕在肋周围并设置在筛管与未穿孔部分之间的环形空间内。

In KP1 type perforated brick masonry, expansion bolt especially design for perforated brick is prefer, because it can form "self- anchor" effect and hold tightly in brick hole.

KP1型矩形条孔烧结页岩多孔砖砌体墙上应采用空心砌体专用膨胀螺栓，因其能够形成可靠的&自螺母效应&。

The pressure drop of airflow consisting of pressure drop of the perforated plate and liquid-layer is mainly influenced by the plate dimension and bare tower velocity, with the increasing of bare tower velocity, pressure drop of the perforated plate increases. The experimental data are used to develop a correlation as follows:ΔpD＝1.04×10－82g This correlation should be used whenβ＜5％,0.299m/s＜u＜

空气流动的阻力主要由孔板阻力和液层阻力组成，孔板阻力主要受多孔板的几何尺寸及空塔速度的影响，空塔速度越大，孔板阻力越大，对实验数据进行回归分析得出的实验关联式为：ΔpD＝1.04×10－82g 公式适用范围：β＜5％，0.299m/s＜u＜

A quasi-double layer perforated structure, with veneer as walls, its space between being 0.08 cm, is built when the outer wall is perforated, with each aperture 1 mm, space length 1.5 cm, and the hard sound absorption material is added to the supported.
