英文摘要：

L. Bachelier’s dissertation Thorie de la Spculation contains many ideas and results about the stochastics process theory. But the opinions about the impact of his works in the history of mathematics has not reached an agreement as yet. Based on orginal materials and relevant studies, this paper concludes that L. Bachelier’s work has a great impact on the development of mathematics, besides economics.
