学习曲线是一种通过生产者行为学习与经验积累而得到改进的生产产出的特征函数，利用学习曲线可以科学地制定成本计划，改善作业计划、劳动定额与劳力规划，质量改善等。对国际上的研究文献、学习曲线的表现形式及其特点进行分析，探讨了几个新的应用动向。

Learning curve is one character function that improves output by the experience accumulation of producer. Learning curve can be used to establish scientific cost plan, improve shop flow scheduling, labor quota and plan, quality, and so on. This paper reviews the research literatures, introduces different forms of learning curve, analyzes their characters, and discusses the future directions of application of learning curve.
