The disturbance model can give the prediction for all the 95 shock events , while stoa model works for 89 events and ispm model for only 72 events . we arrive at 25 . 26 % percentage of all the 95 events with the relative time error less than 10 % , 50 . 53 % of all the events with the relative time error less than 20 % , 65 . 26 % of all the events with the relative time error less than 30 % , 31 . 58 % of all the events with the relative time error between 60 % ~ 80 % 實驗表明,我們的模型在所有95個事件中,渡越時間相對誤差小于10的事件數占總事件數的25 . 26 ;相對誤差小于20的占總事件數的50 . 53 ;相對誤差小于30的占總事件的65 . 26 ;相對誤差在30 60的之間的事件數有30個,占總事件的31 . 58 ;有3個事件相對誤差在60 80之間,沒有哪個事件相對誤差大于80 。

In order to verify the prediction efficiency , 27 interplanetary shock events from january 1979 to june 1982 and 68 interplanetary shock events from february 1997 to january 2000 are used for testing . comparing the results of our disturbance model to those obtained by stoa and ispm , we find that our disturbance model is as good as the other two models , and in some cases even better 為印證擾動傳播模型的適用性,利用79年到82年間的27個激波事件,以及97年2月到2000年1月間的68個激波事件,對激波到達地球軌道附近的傳播時間進行了預測,并將結果與目前流行的行星際激波事件到達地球軌道時間的stoa和ispm預報模型所得結果進行了比較。
