  1. For the 30. 2mm shaft, there are still larger over measure to load. the strength is increased by optimization. for ? 17. 4mm shaft, the strength is increased by enlarge the inner dimension of the spline ; for 30. 2mm shaft, the strength is increased by adjust the structure at the boundary between the key groove and the ring groove, the highest stress of the shaft is at bottom and terminal of the spline after optimization

    其中對17 . 4mm泵軸的優化，通過增大花鍵內徑，提高了花鍵齒底的強度，降低了應力集中點附近的應力；對30 . 2mm電機軸的優化，通過在軸承鍵的環槽端增加倒角，有效降低了該位置的應力集中，使軸的最大應力點從軸承鍵與環槽的交界處轉變到花鍵根部與收尾的交界處，提高了電機軸整體結構強度的合理性。
  2. Then, this paper introduce a new method of measuring the risk ? ? cohesive value at risk ( cvar ), which is more logical than the var on optimizing the portfolio according to the characteristic of the stock bargaining market of our country, it constructs a corresponding index of liquidity risk of the stock assert of the open - end fund, and by constructing a optimized model in cvar, the liquidity risk of stock assert of the open - end fund is efficiently controlled

    接著，本文引入了一種全新測量風險的方法cvar方法，並且根據我國交易市場的特點構造了相應的開放式基金股票組合的流動性風險指標，通過構造cvar調整的投資組合風險優化模型有效的控制了股票資產組合的流動性風險。本文的研究表明: （ 1 ）開放式基金股票組合的流動性風險具有明顯的尾部風險。
  3. Flow details of measurement indicate that the coupling of periodic separated flow ( such as low frequency swinging of separation line ) with nozzle flow may cause aft - end internal flow unsteady. recirculation flow gains more energy from the main flow, at the same time the turbulence intensity increases

    通過對測量結果的分析，我們認為分離流動的周期性（如分離線的低頻擺動）與噴管流動相耦合，會造成燃燒室尾部流動的非穩態效應增強，增加了迴流區從主流中獲得的能量，也加劇了流場的湍流脈動。
  4. Because evt mainly studies extreme value and models the tail of distribution financial return, it can effectively forecasts and guards against the financial risk on the condition of lacking of sample data. more and more people recognize the great potentials of evt dealing with the risk of extreme event. especially evt can be used in application to value at risk due to modeling the tail of distribution

    極值理論主要以極值為研究對象，它注重模擬收益分佈的尾部，比較有效地解決了在缺少樣本的客觀條件下如何預測和防範金融風險的問題，因此，越來越多的人認識到極值理論在極端事件風險管理中的巨大潛力，特別指出的是極值理論是一種模擬收益分佈尾部的理論，所以可以應用於風險價值的測量。
  5. These rules consist of the total fit, the mathematics and fatigue physics, and the safety in tail predictions. an analysis of the test s - n data of 16mn steel weld joints reveals that the four models are reasonable if only considering the total fit as the conventional method did. but if by the present three rules, the appropriate models should be the normal or the extreme maximum value

    根據先前提出的有限數據下良好假設分佈的確定方法，包括三個原則，即假設分佈形狀與誤差數據真實分佈形狀的一致性、預測的總體擬合效果、與疲勞失效機制的一致性和尾部預測的安全性，通過對線性均值s - n曲線擬合16mn鋼焊接頭s - n數據誤差的統計分析，說明應用一般推斷方法， 4種分佈都可合理地作為數據的統計模型，綜合考慮三原則后，極大值和正態分佈是可能的良好假設分佈。
