英文摘要：

It took a long time for mathematics before it attach importance to the applicative of technique from a pure theory research. With the development of informational technology since 20th century, it＇s been common sense among scientists that mathematics should be applied in scientific research and project practice, in which the fusion of mathematical technique and informational technique has played an important part. Discussing the initiation and development of informational and calculative science from this would conduce to a better understanding of this field and its proper position, as well as to educate specific talented workers who would typify the era we live in today.
