Referenced sub-drainage basins were selected in the upper reaches of the Madao main river way, and topographic parameters were obtained using software of River Tools in each sub-drainage. Monthly runoff simulations were then applied to them with the same parameters as Madao catchment, the responses of runoff simulation to topographic parameters were studied, and the Normalization of Runoff-total Length Index were presented. Analyses indicate that NRLI is influenced by source density. NRLI fluctuates tempestuously as source density decreases sharply.

The key to understanding this recipe lies in the definitions of the translate and maketrans functions in the string module. translate takes a string and replaces each character in it with the corresponding character in the translation table passed in as the second argument, deleting the characters specified in the third argument. maketrans is a utility routine that helps create the translation tables.

理解这一配方的关键，在于string模块中 translate 和 maketrans 函数的定义。translate接收一个字符串，并根据第二个参数中传入的转换表，将字符串中的每一个字符替换为相对应的字符，同时删除掉第三个参数中指定的字符（译者注：当translate作为字符串对象的方法调用时，转换表为第一个参数，第二个参数中指定要删除的字符）。maketrans 是一个用来帮助创建转换表的例程。
