波形特徵-
In this paper, researching and producing on current waveform control system of inverter carbon dioxide welding machine is given. the overall plan, the design of hardware structure, the programming and debugging of software is described in detail. the bang - bang and alterable structure discrete pid synthetic control algorithm are used to modulate the width of pwm signal in real time, to acquire the fiat character by driving and controlling the opening and shutting time of igbt, the technology of " double impulse " is adopted to realize electric current waveform control
本文介紹了逆變波形控制co _ 2焊機控制系統的研製，詳細闡述了總體方案的制定、硬體研製及軟體的編寫與調試，採用變結構、離散型pid + bang - bang復合控制演算法、實時調節輸出pwm信號的脈沖寬度，驅動控制用於逆變的大功率開關管igbt的開通與關斷時間，獲得逆變焊機平外特性。 -
The device has considered its practical functions, which include chinese character parameter, waveform display for three - phase current, fixed value and retain of failure information
裝置考慮了實用功能設計。具有漢字參數、三相電流波形顯示，整定值、故障信息的保留等功能。 -
The theory and method in detecting quality defect of concrete filled steel tube arch bridge by ultrasonic wave are summarized, and the parameter character and waveform character of ultrasonic wave through concrete filled tube specimen with regular defects are studied in detail
摘要綜述了超聲法檢測鋼管混凝土拱橋質量缺陷的理論和方法，重點研究超聲波通過鋼管混凝土試件常規缺陷狀況下的參數特徵和波形特徵。 -
For the unit selection strategy, we achieve candidate units for target ones by calculating target cost based on prosodic character vector. then we use viterbi algorithm to select the best synthesis path for simulation speech by calculating concatenative cost of the synthetic waveform, thus a corpus - based speech simulation system comes into being, and speech simulated by this system has the original speaker ’ s style, rather vivid
在合成單元的挑選方面，根據韻律特徵向量，通過計算目標代價獲得候選單元，根據語音合成單元串聯匹配代價，採用viterbi演算法選擇模擬語音的最佳合成路徑，從而初步實現了一個基於語料庫的語音模擬系統，該系統模擬出的語音具有原始發音人的風格，逼真度較高。 -
The results show that, when the depth of the interface is the same as that of the source, the reflected wave is observed in the waveform apparently, and the location of the interface is also observed in the snapshots. the interface can be identified with these characteristics. but when the depth of the interface is not the same as that of the source, the character of the interface is not obvious in the waveform
數值結果表明： 1 、當水平界面與聲源深度不同時，在波形圖中可明顯地觀察到反射波，從波場圖上可觀察到界面位置，利用這些特性可判別地層界面；但當水平分界面與聲源深度相同時，全波列圖中地層界面顯示特徵不明顯。
