1) audiogram
[英]['ɔ:diəugræm] [美]['ɔdɪo,græm]
听阈曲线
2) Threshold curve
阈值曲线
1.
Considering the neglect of spatial correlation of image pixels in current threshold segmentation methods,we propose to combine Hilbert image scan with wavelet transform to obtain a continuous and smooth threshold curve,and then propose a local self-adaptive threshold method in this paper.
阈值的选择是图像阈值分割法的关键,针对现有阈值法中存在的没有充分地考虑图像像素之间的空间相关信息等问题,提出把Hilbert图像扫描方法和小波变换相结合,获得了连续光滑的阈值曲线,从而建立了一种局部自适应阈值法。

Numerical calculations show that in-plane confinement results in the obvious kinks in the threshold curves.
运用Landau-Lifshitz方程,边界处动态磁化强度由有效偶极边界条件约束,研究了无限长金属磁条中自旋波传播的特征,得到了该体系抽运微波磁场的阈值曲线以及色散曲线的解析式,揭示出自旋波激发谱与磁条宽度的具体关系。

2.
Objective To lind out the situations of the hearing loss,which differ from the people without hearing impair- ment in hearing threshold and the balance between ears on their level.
目的:分析听力障碍患者听阈值与正常人的差异及精神心理因素对结果的影响。
