摘　　要：高等数学中"1"的用途很多,通过七个具体实例展示了"1"在高等数学中的特殊地位,特殊用法.there are many uses of the figure ＂1＂ in higher mathematics, for example, it can be seen as the ratio between two non - zero figures, also as the first important limit in the limit solution ; it can also be regarded as the square number of the sine and cosine, the ratio between two non - zero numbers, and a certain varia- ble＇ s zero power in the integral solution. The special position and usage of the figure ＂1＂ in higher mathemat- ics is clearly illustrated by seven examples in the paper, ending with the constant accumulating in the study process of higher mathematics.
