设X（尼尔基）和Y（丰满）为两个径流事件. 、分别为37.5%频率对应

Provided X (Nierji) and Y (fullness) for the runoff two events, respectively runoff frequency corresponding to 37.5%, 62.5% respectively runoff corresponding to the frequency, between the two runoff events X and Y Fengku encounter situations can be divided into the following nine types:

Set X (Nilki) and Y (Plum) for two runoff events. , the runoff corresponding to 37.5% of the frequency, the runoff corresponding to the 62.5% frequency, the dryencounter between the two runoff events X and Y can be divided into the following 9 types:

Let x (nilgi) and Y (plumpness) be the runoff events, 37.5% and 62.5% respectively, then there are 9 types of runoff events between X and y<br>
