| 摘 要： | 本文对间歇射流进行了理论研究,结果表明:间歇射流开启后很快趋于定常,因此,主喷嘴开始供气应比引纬开始早△ι,而各组辅助喷嘴供气应超前于纬纱头端到达该组辅助喷嘴的时间△ι_3,在满足这种超前供气的条件下,用定常假设来研究气流引纬是比较合理的。

| Abstract: | The problem of intermittent air-jet is investigated and resulted that after lapses of a very short time. The air stream is stabilized, in theoretical, the assumption of stable flow could be practically vaild as in study on air-jet weft insertion, in practice, the operation of nozzles is necessarily in advance of the arrival of the weft end. |

| Keywords: | steadiness air-jet air-jet weft insertion Laplace transformation intermit-tent air-jet nozzle |
