能量阈值 meaning in Chinese
threshold amount of energy
Examples
- Image denoising based on energy threshold wavelet packet transform
基于小波包分析的能量阈值消噪 - Threshold of energy of shock wave burst in treating cholelithiasis with shock wave
冲击波体内胆结石爆破效应的冲击能量阈值 - The electronic temperature , intensities of all lines and continuous spectra gradually increased with the increment of laser energy , and they got to maximum at different laser energy . our results of copper and aluminum show that there are possibly different thresholds of laser energy to electronic temperature and intensities of emission spectra of laser ablated plasma . at the different environmental gas pressure , spatial emission intensity distribution is explained by the competition among " heat reservoir effect " , " confined effect " and " s hadow effect "
认为cu等离子体羽的发光机制是由电子与粒子的碰撞传能、电子与离子的复合形成的；随激光能量的增加， cu等离子体特征辐射(分立谱) 、连续背景辐射(连续谱) 、电子温度都出现最大值；结合对al的实验结果说明：激光烧蚀金属产生的等离子体，其特征辐射、连续辐射、电子温度可能都存在一定的能量阈值；背景气压对激光烧蚀等离子体谱线的影响，其机理可以认为是“热库效应” 、 “约束效应”及“阴影效应”相互竞争的综合结果。 - E xperiments show that the amended method is better than that in reference 12 . as the same time the method can combine with the wavelet transformation to locate the characters . by multi - resolution analysis and pyramid decomposition , the edge components with different spatial resolutions and different directions can be acquired , among which , the detail components have the most distinguished texture features standing for the object region , then by further morphological operations , the useless information is greatly decreased and the last object text region is acquired
分析了各个方向边缘经小波变换后的特点，用具有良好时频局部和变尺度特征的小波分析方法提取出不同空间分辨率，水平和垂直及对角线方向的边缘子图像，把满足水平和垂直方向能量阈值区域进行合并，经过去噪后，用对角线方向能量阈值即高高频能量作为判断标准，确定是否是真正的字符区。
