The tumor may prolapse through the orifice . 肿瘤可脱出幽门口。
The valve shown has a pilot and a bleed orifice . 该阀具有控制孔和流出孔。
The concentric orifice is most frequently used type . 同心圆孔板是最经常使用的形式。
The density p is that of the fluid escaping from the orifice . 上式中P是从小孔喷出的流体密度。
The beltless machine, sometimes called a "fixed" orifice pasting machine . 无带式涂片机，有时称为“定位”出口涂片机。
Both variable orifices and electromagnetic controllers have been used with success . 可变锐孔和电磁流量控制器都已成功地使用。
The distance between orifice groups is another parameter associated with stability . 喷孔组合之间的距离是与不稳定性有关的另一参数。
As previously mentioned, spacing of the orifice groups with relationship to each other is important . 如前所述，喷孔组合的相互间距是重要的。
Improvement of the orifice discharge coefficient may not result in stability improvement as illustrated in one test series . 由一系列的试验说明，喷孔流量系数的改善并没有导致稳定性的改进。
Some designers use metal strips at the section where the orifices are to be, thus avoiding the difficulties of filing dissimilar materials . 有些设计员在钻孔的剖面上使用金属狭条，用以避免修锉不同材料所遇到的困难。
