用数学形式描述自然现象似乎是人类的需要.大概人们希望从中发现一些规律和方法,以便能够了解和控制自然.就如地震那样,初看起来似乎很难与数学中的对数之间有什么关联.但用其测量地震强度大小的方法,却把两者联系起来.美国地震学家C·F·里兹特,在1935年设计了一种里氏震级.那是根据地震的震中释放出的能量来描述的.里氏震级是释放能量的对数.里氏级数上升1级,地震仪曲线的振幅增大10倍,而地震 Describing natural phenomena mathematically seems to be a human need, and probably people want to find some laws and ways to understand and control nature, as it did to earthquakes, at first glance, However, the method of measuring the magnitude of the earthquake, however, linked the two, and the American seismologist CF Leedster designed a Richter scale in 1935. It was released according to the epicenter of the earthquake The magnitude of the Richter scale is the logarithm of the energy released, the magnitude of the Richter series is increased by one and the amplitude of the seismograph curve is increased by a factor of ten, whereas the magnitude of the earthquake
