smoothed curve 中文意思是什麼
smoothed curve
解釋
光滑曲線-
During the test procedure, the compliance test method is adopted to increase the load cyclically until the crack extends over the height of the specimen. then the record data are rationally smoothed and calibrated for next use, at the same time, the response on the tail of measured curve is expressed in mathematical function to eliminate its errorous influence on gf
在測試過程中採用了柔度測試法以循壞的方式增加荷載直到試件完全斷開，然後對試驗曲線進行了合理的光滑處理，並對試驗曲線的尾部進行了擬合表達盡量消除其對結果的誤差影響。 -
First the object contour is translated into a 1 - d contour curve. secondly the curve is smoothed to restrain the noise. the number of peaks of the curve is achieved as well as the areas which contained between adjacent peak - valley, then the latter is followed by discrete fourier transformation ( dft )
首先將目標輪廓轉換成一維輪廓曲線，平滑去噪，然後獲得曲線峰數和輪廓曲線在相鄰峰谷間所含面積，並對後者進行dft變換，提取出具有平移、旋轉、尺度不變性的兩類特徵。
