Through the experimental research, we think : the technological capacity of fiberglass asphalt macadam if weaker than asphalt macadam, however, if use elasticized capacity to solve blending technological problem. adjust the breed of fiber silk, extend its diameter, its paving capacity is still worth exploring, asphalt - rubber macadam structure lager have good deformed - become capacity and crazed - resistance capacity, small gap rate. good water - resistance capacity, good hot - stability and simple construction technology. therefore. pitch rubber spall is a good cover material which is suitable for the second class or lower whose asphalt pavement has split open because of fatigue. and is the good structural measure of preventing half - rigidity grass - roots unit shrink - rift reflecting. pave a thin layer of pitch rubber spall between asphalt - type pavement layer and half - rigidity basic level, although the cost of building is higher than paving togongbu in the middle, the construction technology, crazing - resistance and water - resistance are better than togongbu, not only could reduce greatly the reflex of half - rigidity grass - roots unit material, long then the use lifespan of pavement, but also it is possible to reduce suitably the thickness of asphalt mixture layer, though the cast of building in the early days becomes more, in the long - term opinion, it have fully important technological and economical significance
通過試驗研究認為：玻璃纖維瀝青碎石的技術性能不如瀝青碎石好，但路用彈性性能較好，如能解決拌和工藝問題，調整纖維絲的品種，增大其直徑，其路用性能仍值得探討，瀝青橡膠碎石結構層具有變形性能和抗裂性能良好，空隙率小，防水性能好，熱穩定性較好，施工工藝簡單的特點，因此，瀝青橡膠碎石是二級及二級以下公路因疲勞而開裂的瀝青路面的良好罩面材料，也是防止半剛性基層收縮裂縫反射的良好結構措施，在瀝青類路面面層和半剛性基層之間夾鋪瀝青橡膠碎石薄層，雖然造價比夾鋪土工布高，但其施工工藝，抗裂性能和防水性能均優于土工布，不僅可以大大減少半剛性基層材料的反射裂縫，延長路面使用壽命，而且可能適當減薄瀝青混合料面層的厚度，雖然初期造價有所增加，從長遠來看，具有十分重要的技術和經濟意義。 -
Firstly, we study the construction of emotion - speech template database, and analyze the common features such as pitch, energy and formant. after choosing the useful features by using fuzzy entropy effectiveness analysis, we get better performance with the application of neural network. in addition, we propose some more efficient features such as speech rate, pitch slope, mel - frequency cepstral coefficients and its transient parameters, and design a processing model based on vector quantization for cepstral features to fusing different features
本文首先介紹了情感語音數據庫的建立情況，然後研究了基音頻率、振幅能量和共振峰等目前常用的情感特徵在語音情感識別中的作用，並且通過一種基於模糊熵的特徵有效性分析方法進行了有效特徵的篩選，應用人工神經網路建立了初步的語音情感識別模型，經過實驗發現特徵篩選后系統的識別效果有著一定程度的提高。 -
He would come up, close, co - altitude, within about three to five feet, was making gestures, pulled back a little bit, came back up again and made some more gestures, and then the third time his closure rate was too far. instead of under - running, he attempted to kind of turn and pitch up, and that was when his vertical stabilizer - - where it meets the fuselage of the aircraft - - impacted my number one propeller, basically pretty much tearing his aircraft apart
他追上來、靠近、與我們同一高度，距我們約3英尺到5英尺以內，他做了幾個手勢，後退了一點，再次追過來並做出更多的手勢，然後他第3次靠近，這次他離得太近了。他不是在下方飛行，而是試圖做出某種轉身和提拉，此刻他的垂直穩定翼同機身相接的地方撞到了我的1號螺旋槳，他的飛機基本上就斷裂了。 -
In this thesis, the research focuses on pitch detection techniques of the low - rate wi speech coding. aimed at the problems of voiced - unvoiced error, pitch doubling and halving, accuracy of pitch detection and pitch quantization, a series of pitch detection techniques including pre - processing, pitch detection and pitch quantization were proposed
本文就低速率wi語音編碼中的基音檢測技術進行了深入研究，針對基音檢測中的清濁誤判、基音加倍減半、基音檢測精度及基音量化問題，提出了包括基音檢測前端處理、基音檢測演算法及基音量化的一整套基音檢測技術。 -

Mandarin tone is characterized for tone level and tendency of pitch curve, so head - tail difference and relative tone level rate are determined as tone features for chinese tn - syllable word ; head - tail difference and tone level at the beginning of syllable are determined as tone features of syllable in continuous speech
漢語聲調主要由基音曲線的調位高低和走向決定。因此，本文選擇頭尾差和相對調位比作為三字詞音節的聲調特徵；選擇頭尾差和音節起點調位作為連續語音中音節的聲調特徵。 -
To solve the problems caused by the varieties of the missile dynamics with the difference of flight height, velocity and attitude angle in modeling the missile, in this thesis, the theory of variable structure model reference adaptive control is used to design a pitch channel autopilot based on a longitudinal missile model, the status equation using the measurable parameters of load and angular rate is established, and the methodology to choosing the reference model is discussed also, and the performance of the controller is analyzed by means of simulation
為了解決攔截彈氣動參數隨飛行高度、速度、姿態的不同，變化范圍大，控制系統難以準確建模的困難，基於縱向平面攔截彈模型，採用模型參考變結構控制理論設計了俯仰通道姿控復合控制系統，以可測量變量過載和角速度作為狀態量建立了系統的狀態方程，討論了參考模型的選擇方法，並對系統的性能作了模擬分析。 -
Pitch detection is one of the most important tasks in low - rate speech coding field. the accuracy of pitch detection will affect the performance of the whole codec
基音檢測是低速率語音編碼領域的一個非常重要的問題，準確檢測語音信號的基音周期非常關鍵，它直接影響到整個聲碼器的性能。 -
In traditional low bit - rate speech coding, considering that ears are not sensitive to phase information, the phase information is often neglected, and this will result in coarse and harsh speech quality, and it even may lead to inflection in pitch
在傳統的低比特率語音編碼中，考慮到人耳對相位信息不敏感而經常忽略相位信息，這將導致語音粗糙、刺耳甚至音調發生改變。為了獲得高質量的聲碼器，語音的相位信息是不能不考慮的。
