  1. Then, a new adaptive, on - line, fast samplingstrategy - multi - scaling sampling - is presented inspired by mra multi - resolution analysis and shannon sampling theorem, for quicklyobtaining acceptably approximate association rules at appropriate samplesize. both theoretical analysis and empirical study have showed that thesampling strategy can achieve a very good speed - accuracy trade - off

    但是，取樣策略必須在演算法的效率和結果的精確性之間進行很好的折中， 「如何確定合適的樣本大小使得運行於其上的關聯規則挖掘滿足精確性的要求取樣復雜性」成為這一方法的關鍵難解問題。
  2. The transient analysis and simulation studies in time - domain showed that the transient capacitance current of busbar is unable to be caught due to the limitation of the given sampling frequency, therefore the transient current singularity of the fault line and the non - fault line will approximate, which prevents to identify the fault line with the criterion calculation result of transient current protection

    研究結果表明，線路出口故障時暫態電流保護完全失去選擇性的根本原因是，在給定的采樣頻率的限制下，難以捕捉到過渡過程中極其短暫的母線分佈電容中的暫態電流，從而故障線路與非故障線路暫態電流波形的奇異性相近，根據故障線路和非故障線路的暫態保護判據計算結果不能正確識別故障線路。
