利用雙累積曲線分析原理來進行斷點測定以找出一組以累積面積百分值（CA）及其對應累積流量（CQ）的降序逕流資料系列之斷點。斷點後一點開始的所有資料點稱為直線慣性串，此慣性串資料所構成直線模式可以客觀地推估一個島嶼或一個國家的總逕流量。本文包括二個應用例。

A break point test applied in double-mass analysis is employed here to distinguish the break point of the descending runoff data series through the use of the cumulative area percentage (CA) and corresponding cumulative discharge (CQ). The point next to the break point leads a series of data points called the "linear inertia chain". The data to be included in this chain should build a good linear relation by plotting CA against CQ. This linear model resulting from consideration of linear inertia chain; therefore, provides a tool to estimate the runoff volume over a large area such as a nation or an island. Two examples were performed to test this method.
