storage-elevation curve

The main results are as follows: ( 1) The changing pattern of storage root thickening rate expressed a double-peak curve, the first peak appeared at 50~ 70 DAP ( days after planting), and the second peak appeared at 120~ 165 DAP.

结果表明：（1）块根膨大速率变化动态呈一双峰曲线，第一个高峰出现在栽秧后50～70d，第二个高峰出现在栽秧后120～165d；

Finally, the inability to make the storage curve of four parameters by the theory of unsteady flow is discussed and the conclusion that it is unnecessary to offer the storage curve of parameters to flood routing computation by the computer method of unsteady flow is reached.

文章最后还就用非恒定流理论制作四参数库容曲线的不可行性及用非恒定流电算方法为调洪演算提供多参数库容曲线的不必要性等问题进行了讨论。
