型孔喷口的最小特征尺寸采用微细电火花逐层扫描加工得到。
Then the smaller feature size of spout holes is achieved by micro-EDM with layer-by-layer scan machining.
结果表明在喷喉尺寸固定且在喷口强度允许的条件下，喷口直径越大越有利于提高火箭发动机的推力。
The result show that the bigger of the diameter the higher of the assisted power of the rocket engine with the dimension of the throat is constant and the permit of the spout intensity.
