下午好 ！
假设我们有来自单词的这些引文：
[1] Yang, Xin-She - Optimization techniques and applications with examples-John Wiley & Sons (2018)
[2] (Frontiers in applied mathematics) C. T. Kelley - Iterative Methods for Optimization-Society for Industrial and Applied Mathematics (1987)
[3] Marco Cavazzuti (auth.) - Optimization Methods_ From Theory to Design Scientific and Technological Aspects in Mechanics-Springer-Verlag Berlin Heidelberg (2013)
我正在寻找一种将它们转换为乳胶格式的快速方法（例如：免费在线服务、转换器......）。
谢谢你的帮助 ！
