throat diameter

基本解釋

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.
結果表明，內噴管喉徑是影響環(huán)簇式塞式噴管尺寸大小的最主要設計參數(shù)；
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暫堵技術還存在某些方面的問題，如采用儲層平均孔喉直徑和主要流動孔喉平均直徑所帶來的問題。

Experimental study for such was carried out on established test rig with flat, converging and converging diverging nozzles of different throat diameter, shape and diverging angle.
為使流經縮放形噴管的低溫熱水得到充分膨脹和加速，在此對縮放形噴管的喉部及擴張段進行實驗對比分析。
