中文拼音 [zhēngqiējībiàn]
正切畸變
英文
tangential distortion-
The detailed works are as follows : the finding patterns problems in the time - series data sequence are described, and a new trend logic expression method is introduced, and its algorithm and experiment result of algorithm are given ; time - scries data are disposed, and using the arctg. slope of line as the sample of pattern recognition, so ignoring the aberrance of pattern in the classified. in addition, a new time - series pattern finding algorithm based on higher - order neural network is put forward
同時給出了本文的具體的工作，主要是：對在時序數據序列中發現模式問題進行了描述，並介紹了一種新的趨勢邏輯表示方法，給出了其演算法及演算法的實驗結果；對時序數據進行處理，提出了利用線段的斜率反正切值作為模式識別的樣本，從而在分類時忽略模式的畸變；另外，還提出了一個新的基於高階神經網路的時序模式發現演算法。This paper put forward a method of using amending sine value in the spwm sine table. this method can correct the distortion of the output voltage waveform, which resulted from the dead time used to the voltage type whole bridge main circuit. the inverter system adopts digital fuzzy controller with feed forward correction and which proportion coefficient and integral coefficient is changeable, so dynamic response is improved
本文提出了一種採用修補spwm正弦表值的方法，用以改善電壓型全橋逆變主電路因上下橋的功率器件切換時先關斷后導通的死區時間而引起的輸出電壓波形畸變；逆變系統採用帶前饋校正的變比例變積分系數的模糊控制器，提高了系統的動態響應指標；系統設計了完善的保護措施，並具有市電電網的故障診斷功能。Based on mr. zhang zhengyou ’ s plane template two - step method, three aspects of improvements have been made. firstly, tangential distortion adjustment is added into the camera imaging model. secondly, after the detailed research aiming at the step of computing the initial guess of camera parameters, some improvements are made within the corner selection and computation
從三個方面對張正友的平面模板兩步法作了改進:首先，在攝像機成像模型中增加了切向畸變校正;然後針對計算攝像機參數初值環節進行研究，在角點選取和計算方法上作了改進。With a case, the theory proposed in this paper is compared with the traditional distortion theory which does n ' t take shear deformation into account and ansys finite element software to verify the accuracy of the proposed method. it is drawn that taking shear deformation into account results in a fairly higher accuracy
隨之，通過實例，將本文理論與傳統不考慮剪切變形的畸變分析理論及州sys有限元軟體的分析結果作比較，驗證了本文理論的正確性，結果還表明考慮剪切變形的影響大大提高了考慮畸變效應的計算精度。The control of the spatial mid frequency wavefront distortion was achieved based on our cri wavefront sensing and lctv wavefront correcting system. the results of our research show that crs interferometer can be used to diagnosing the mid and low frequency wavefront distortion of a laser beam and lcslm can be used to availably controlled it
通過以上研究，說明我們建立的環路徑向剪切干涉儀可以用於icf激光驅動器的中低段波前畸變的檢測，並且液晶空間光調制器可用於它的前級中存在的中頻段波前畸變的校正。分享友人
