摘　　要：总结有关液丝破裂研究的实验工作,分析Weber数、流体粘度及初始扰动对液丝破裂的影响。简要介绍牛顿流体和非牛顿流体的一维、二维数学模型,并指出该研究的实际应用和展望。一维模型在最近几年被广泛使用,极大地增强了人们对液滴形成过程中界面破裂的理解,但不能同时得到精确的宏观特征和微观特征；三维模型的计算量庞大。为了研究的可行性和结果的精确性,应对二维模型进行更多研究。Experimental analysis of breakup of liquid filament in literature was reviewed. The effects of the Weber number, viscosity and initial perturbation on breakup of liquid filament were analyzed. One-dimensional and two-dimensional models for Newtonian and non-New/onian fluids were presented. One-dimensional models have been used by many investigators over the last few years to greatly enhance our understanding of interface rupture during drop formation. However, these models are not able to capture simultaneously both the macroscopic and microscopic features. Moreover, the computing tasks of three-dimensional simulation were enormous and expensive. Therefore, we should pay more attention to two-dimensional models.
