  3. The factors include antecedent precipitation of low flow period and status of karst basins ( such as lithology, landform, drainage area, drainage density, length and ratio of demotion of main river and so on. ). based on the former studies, integrated the conventional statistic methods, the technique of anns is applied in this paper for researching the law of the low flow of karst basins in guizhou altiplano

    影響喀斯特流域枯水徑流的因素異常復雜，其影響因素主要有枯季前期降水量和巖性、地貌、流域面積、河網密度、主河道長度及其比降等流域下墊面狀況。本文在前人研究的基礎上，採用人工神經網路技術，結合傳統的統計方法，研究貴州高原上喀斯特流域的枯水徑流規律。
  4. The statistics show that the correlation of antecedent precipitation, lithology, landform, drainage density, drainage area, length and ratio of demotion of main river and four characteristics of low flow is very complex

    統計結果表明：流域的枯季前期降水、巖性、地貌、流域面積、河網密度、主河道長度及其比降等因子與喀斯特流域的枯水四特徵的相關關系異常復雜。
  5. This paper also indicates that the long - term target for adjustment productive forces of inland waterway transport is not only to maintain investment for a long period, but also to use advanced equipment and technique to raise working efficiency of inland waterway transport

    並且指出內河航運生產力要素的長遠調整目標，是根據內河航運的資金密集型行業的特點，長期持續保持投資強度，以形成完善的航道、港口基礎設施，同時運用現代化的先進設備技術完成傳統行業改造，從而大幅度提高內河航運生產率。
  6. Experimental process shows that variance of underwater distributary channel and declining rate of lake plane are closely related to moving intension of motive soleplate

    實驗過程顯示，水下分流河道的變遷與湖平面的下降速率及活動底板的運動強度密切相關。
  7. Comparing with the current observations, which include the number density distribution in space, mass function, etc., the so - called standard modes for both the power law and gaussian cluster initial mass functions are selected among many runs of simulations. the deviation from the standard modes, which is resulted from the change of the parameter for the initial conditions, is discussed in detail. the discussion of the model parameters is also presented although they are adopted as the typical values based on previous work

    對應一定的初始分佈我們發現無論是冪律的還是對數高斯的球狀星團初始質量譜經過長時間的動力學演化都會得到和現在銀河系觀測到的球狀星團系統相符的對數高斯的質量分佈；動力學演化會明顯地改變球狀星團系統的空間密度分佈，靠近銀心區域的球狀星團瓦解得更多；經過動力學演化后的球狀星團速度分佈函數在靠近銀心的區域明顯得不同於初始分佈，初始擁有較大軌道偏心率的球狀星團更容易瓦解。
