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，从而肯定了非轴对称模式在射流破碎中的重要作用 In this paper, we use the theory of linear instability to study the fracturing of high-velocity viscous liquid jets. For the first time, we use the advanced high-speed sub-frame holography to systematically observe the manifestation of several unstable modes. The experimental observations are in good agreement with the theoretical predictions . The results show that under the proper conditions, the non-axisymmetric mode is also likely to be the most unstable mode, which confirms the important role of non-axisymmetric mode in jet breakage
