摘要
本文利用线性不稳定性理论研究了高速粘性液体射流的破碎问题，并利用先进的高速分幅全息摄影技术首次比较系统地观察了几种不稳定模式的表现形态，实验观察结果与理论预测基本一致。研究结果表明：在适当的条件下，非轴对称模式也有可能成为最不稳定模式。
The breakup of a high speed viscous liquid jet is studied by the linear instability theory in this paper. An advanced high speed multi frame holography is for the first time employed to observe the structures of unstable modes. The experimental observation agrees fairly well with the theoretical predictions. The results of this paper demonstrate that asymmetric mode can be the most unstable mode under specific conditions. This confirms the important effect of asymmetric mode on the breakup of a liquid jet.
