曲率比
Therefore, a method of decomposing human body silhouette is put forward. In this method, body silhouette is primarily divided into segmentations depends on the negative curvature extreme points, under the limit of the ratio between arc length and secant line.
该方法依据人体轮廓上的负曲率极值点,在轮廓弧长与割线比值的限定下,对人体轮廓进行初步分解。
Experience shows that the decisive factors for predicting hydrocarbon are the apparent polarity, amplitude ratio ( KZ~ 6), and instantaneous phase(φ) of the reflection from the top of Yangxin formation, as well as the curvature(ρ) of the upper surfaee of this formation.
经验表明,阳新统顶部的视极性及振幅比(KZ~6)、瞬时相位(φ)和阳新统顶的构造曲率(ρ)是预测气况的决定因素。
