  1. Analysis of the variability of circadian heart - rate in patients with type 2 diabetes combining with cardiovascular diseases

    培哚普利對2型糖尿病合併心腦血管疾病心率變異性的影響
  2. Take middle - east district of taipusi banner as study area in the paper, combining field observation test ( pumping test and field survey ) with indoor experiment ( granule analysis and organic matter analysis etc ), based on the relationship between hydrological parameters and physical - chemistry characteristic parameters of formation, the variability of aquifer parameters and physical - chemistry parameters of unsaturated zone have been also analyzed. the aquifer system of the taipusi banner is identified and analyzed by using the internal and outside information. on the basis of real pumping of ground water, the water resources evaluated by the water balance method

    本文以太僕寺旗中東部地區為研究區域，採用野外試驗（抽水試驗、實地調查）和室內實驗（顆分、有機質等實驗）相結合的方法，推求了研究區含水層系統的水文水利參數，在系統模擬含水層水理參數與巖性物理化學特徵參數之間的關系基礎上，進一步分析了含水層參數及其包氣帶的物理、化學特徵參數的空間變化特徵，並利用其內外部信息對太僕寺旗含水層系統進行了辯識與分析；以現狀地下水開采量為依據，採用水均衡法評價了研究區水資源總量，並利用有限單元法來模擬分析驗證。
  3. The predictive value of heart rate variability is independent of other noninvasive measures commonly used to predict prognosis of cardiac diseases, low left ventricular ejection fraction, and so on. like other risk predictors, measures of heart rate variability have modest positive predictive accuracy when used alone. however, combining measures of heart rate variability with other risk predictors yields a positive predictive accuracy of about 50 %

    心率變異性的預測價值獨立於其他非創傷性預測心臟疾病預后指標（降低的左心室射血分數，頻發重復性室性心律失常等） ，在單獨應用時陽性預報率較低，但與其他指標聯合應用，陽性預報率可達50 。
