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。 -
It is thus of importance to develop an l - band edfa. however, a conventional l - band edfa is relatively inefficient and has low gain and high noise figure since they are operated at the tail of the erbium gain band. therefore, it is very important to design and analyze a high performance l - band edfa with simultaneously high gain, low noise and low gain ripple for a dwdm system
開發新的l - bandedfa是十分必要的，然而傳統的l - bandedfa由於工作在鉺光纖增益譜的尾部，其存在增益低、工作轉換效率低、噪聲大等缺點，因此，分析和設計符合dwdm系統發展要求的具有優良性能（高增益、低噪聲、動態增益均衡）的l - bandedfa是十分有意義的。 -
For a conventional helicopter, the tail rotor is one of primary sources for helicopter noise
