以前已经证明，在电场的帮助下，可以从聚合物熔体中产生精细的射流。为了了解射流形成的机制，对熔融聚合物（尼龙12和聚乙烯）在电场作用下的垂坠液滴的变形进行了初步实验。液滴变形是作为场强和频率的函数来测量的，结果用Torza等人提出的理论来解释。结果表明，理论与实验结果在定性上是一致的。这允许识别影响水滴变形的参数，并导致变形机制的定性图像。
It has been previously shown that fine jets can be drawn from polymer melts with the aid of an electric field. In an effort to understand the mechanism of jet formation, preliminary experiments have been carried out on the deformation of pendant drops of molten polymers (nylon 12 and polyethylene) subjected to an electric field. The drop deformation was measured as a function of field intensity and frequency, and the results were interpreted in terms of a theory due to Torza et al. It is shown that there is qualitative agreement between the theory and experimental observations. This permits the identification of the parameters influencing the drop deformation and leads to a qualitative picture of the mechanism of deformation.
