throat diameter

基本解释

The results show that throat diameter of the inner nozzle is the most important design parameter influencing structure size of the annular clustered plug nozzle.
结果表明，内喷管喉径是影响环簇式塞式喷管尺寸大小的最主要设计参数；
But there are some deficiencies in temporary plugging technique, for example, the problems in adopting the reservoir average pore throat diameter and main flowing pore throat.
但是目前普遍采用的暂堵技术还存在某些方面的问题，如采用储层平均孔喉直径和主要流动孔喉平均直径所带来的问题。
