At one time complex structure and area of weariness crack ( including whole suspension hollow axis of swivel, half suspension adopted axletree, substituting holistic grinding steel wheels for wheel - hoop compounded wheels, different wheel - axletree structure of different locomotives, different transmission chamfer machining step of axletresses and driven traction gear etc. ) centralizing make wave clutter and repeat to disturb recognition of real fault wave
同時，由於全懸掛空心軸、半懸掛抱軸承等復雜結構車軸的使用和整體碾鋼輪陸續替代輪箍組裝式車輪，各型機車輪軸結構不同，車軸加工臺階和過渡圓角不同，從動牽引齒輪與車軸採用過盈裝配等，在這些結構復雜且疲勞裂紋產生集中的區域，探傷時極易發生波形交織和重復，難以識別真正缺陷波。 -
According to similar ft3 frame format and its checkout mode of dnp data link layer, the relationship between fer ( frame error rate ) and ber ( bit error rate ), frame length is deduced. the computation formulas of average transmission times and repeat transmission times guaranteeing the correct transmission of telecontrol information are given as well
根據dnp3 . 0規約數據鏈路層類ft3幀及其校驗方式，推導出幀傳輸失敗概率（誤幀率）與通道誤比特率和幀長的關系，同時給出平均傳輸次數和重復傳輸次數的計算公式。 -
In communication systems, there are mainly two methods for controlling transmission errors, one of which is forward - error - correction ( fec ) and the other is automatic - repeat - request ( arq )
數據傳輸系統中有兩種技術被用來控制傳輸錯誤：即前向差錯控制技術（ fec ）和自動要求重傳技術（ arq ） 。 -
Based on the requirement and target of the projects, firstly, pcf bragg grating are investigated theoretically and experimentally. moreover, the effects of filling high refractive index material ( nematic liquid crystal, nlc ) in pcfs on the transmission mechanism and propagation properties are studied by using plane - wave method and finite - element method ( fem ), farther, several novel pcfs are proposed and designed. lastly, we propose and demonstrate a clad - pumped er3 + / yb3 + - codoped fiber laser, which integrate all performances of broad - band tunable wavelength, uniform output power spectrum, high repeat frequency and high average power to together
本論文選題于國家973 、 863以及國家自然科學基金等項目，結合課題的要求和主要目標，在對光子晶體光纖（ pcfs ）傳輸特性研究的基礎上，首先對光子晶體光纖光柵進行了理論和實驗研究;然後，採用平面波展開法和有限單元法分析了在光纖的空氣孔中填充高折射率液晶對光纖傳導機制和傳輸特性的影響，提出並設計了幾種新型光子晶體光纖;最後，提出並研製成功連續可調諧、輸出功率譜均衡的全光纖化、高功率包層泵浦鉺鐿共摻光纖激光器實驗樣機。 -
Sequential call, repeat call, random call, priority call in multi - operations, disposal of jumping the queue, transmission, booking and breaking the ranks, etc
順序呼叫，重復呼叫，任意呼叫，多業務優先呼叫。插隊，轉移，預約，掉隊處理等功能。 -
Arq ( auto repeat on request ) is used in data communication to garauntee error - free transmission, but it is not suitable for video communication because video communication has stringent delay requirement and limitless retransmission is not allowed
傳統的數據通信通過出錯重傳的方法保證數據的無差錯傳輸，但是這種方法不適合實時視頻通信。因為視頻通信對延遲有嚴格的要求，不可能使用無限制的重傳。
