曲线光滑 meaning in Chinese

fairing of curve
line smoothing

Because limited by the sampling channel of transient electromagnetic measuring depth fieldwork curve ( generally 20 ~ 40 channels ) , the smoothing degree of fieldwork curve is not very good , it make against the differential imaging treatment . in order to hold the continuous change characters of the curve and seek the voltage exactly , we use the thrice spline insert number function to reconstruct the fieldwork data ; 4
) t ； 3 .由于受瞬变电磁测深实测曲线取样道的限制(一般为20 ~ 40道) ，实测曲线光滑程度较差，不利于微分成像处理，为了更好的把握曲线连续变化的特征及准确求导，采用了三次样条插值对实测数据进行重构;续
