查询词典 convoluting

Taking Guixin highway as a case, the pollution state and its change regularity in vertical direction are analyzed, which proves that the heavy mental pollutant enriches within 5m under the ground and decreases towards ground surface but increases near the surface slightly that may have something to do with the convoluting and accumulating effects of tail gas.

文章以贵新路为例，分析了公路边坡土壤重金属污染物的垂向污染状况和变化规律，得出了路坡重金属污染的富集带约分布在距地面5m处，随着高度的增加污染物含量减少，但到了路坡坡顶又出现小幅增高现象，这有可能与汽车尾气卷扬和淀积效应有关。

Assuming a one-dimensional signal, features correspond to points of the maximal Fourier phase congruency; for a two-dimensional signal, phase congruency is obtained by convoluting signal with two filters in quadrature.

对于二维信号，相位叠合可通过一对相位正交的滤波器得到，最常用的滤波器是Gabor滤波器的偶和齐的滤波器。

Methods External form of cranium was reconstructed by convoluting and exchanging skull′s flap combining with plum blossom bone flap.

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
