雨量強度為水利工程中常用之設計值，在小流域因集流時間短，物部公式為利用R24提供短延時之雨量強度設計值之常用工具。由於普通雨量站僅能提供日雨量紀錄，因此在研究區域僅有普通（日）雨量站，而無自記（時）雨量站之情況下，無法套入物部公式內使用。
在台灣普通（日）雨量站較自記（時）雨量站的數量為多，具有較高之空間密度。但自記雨量站因具有時雨量紀錄，因此在時間尺度上較普通雨量站為佳。為綜合普通與自記雨量站分別在空間與時間尺度之優勢，以充分利用水文紀錄，利用自記（時）雨量站的資料，探討24小時強度雨量與一日暴雨量間的關係，並將其比值繪成等值線圖。將兩者在空間尺度上的關係建立起來，以提供未來規劃設計時，能充分利用普通雨量站之雨量紀錄，來彌補雨量資料不足時之參考。

The precipitation strength is an in common use design value in the marine hydraulic engineering. At small because the river valley gathers to flow time short. A formula in thing is to make use of the R24 to provide short postpone in common use tool of the precipitation strength design value of the hour. Because the common precipitation station can provide the rain gauge of the day to record only. Therefore at study there is only common( day) precipitation station in district. And have no to rain from the condition of recording( hour) the precipitation station. Can't the set go into a formula in thing the usage.

Compare in the common( day) precipitation station in Taiwan to is many from the quantity of recording(hour) the precipitation station. Have the higher space density. But from record the precipitation the station because have the timely rain quantity record. Therefore on time dimensions the more common precipitation station is good
For synthesizing the commonness and from record the precipitation to stand to distinguish in the advantage of the space and time dimensions. To take advantage of hydrology record. Make use of from the data of recording( hour) the precipitation station. Inquire into the strength precipitation of 24 hours to measure the relation of with rain-storm on first. Also draw its specific value equivalent line diagram. Get up in the space the relation on the dimensions establishment both. To provide to program the design in the future. Can take advantage of the precipitation record of the common precipitation station. Come and make up the reference of the not enough hour in precipitation data.
