The distributions of the values of fluctuating pressure conform to the law of normal distribution ; and the dominant frequency is low frequency
脈動壓強幅值分佈符合正態分佈規律，優勢頻率為低頻。Secondly, my paper researched low flow frequency analysis in karst drainage and selected four types of the theoretic frequency distributions. log - normal distribution and p - iii distribution are applicable to low flow frequency analysis in karst region by caculating and comparing. furthermore, the low flow frequency distrbutions are almost same in these drainages of different types of landforms
二是對喀斯特流域的枯水頻率分析作了初步研究，選擇了四種理論頻率曲線經過計算和比較，得出適用於喀斯特地區枯水頻率分析的線型是對數正態分佈和皮爾遜?型（ p ? ）分佈，並且流域中地貌類型的差異對枯水頻率曲線的選擇幾乎是無影響。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。
