concavity

基本解释

It is evident that curvature of doming whether on the crest (convexity) or on the flanks (concavity) have no major effect on fracture densities.
很明显，穹窿的曲率在波峰（突起）或两翼（凹陷）对断裂密度都没有很大影响。
Importing the concavity map into the displacement channel, I applied the map as a displacement at a level of 0.01 to the model.
进口的凹凸映射到位移通道，运用地图作为位移在0.01的水平的模型。

The results showed that a concavity in the surface could be clearly observed at the center of starches.
结果表明：微波淀粉颗粒表面出现凹坑，降低了膨胀度和溶解度、冻溶稳定性。

His memory was able to adhere to her smoothness, to her rough parts, to her every swelling and concavity, but only in a way that was like an ache—like a hunger feeding upon itself.

All confines of gray scale are segmented into some parts, and multiple threshold is derived through in each part histogram of gradient, concavity analysis of histogram, moment and entropy of histogram. The multiple threshold image segmentation is achieved.
在基于阈值选取的图像分割方法中,本文改进了传统的迭代阈值法和基于梯度、凹度分析、矩、熵的单阈值分割方法,将灰度范围进行了划分,并根据各灰度区间的梯度直方图、直方图的凹度分析,直方图的矩、熵得到多个阈值,实现了图像的多区域分割。
