查询词典 coefficient of covariation

Using covariation concept in array signal processing, the proposed algorithm can obtain clean speech signal subspace by eigendecomposition of the covariation coefficient matrix of speech signal corrupted by impulsive noise.

该算法把阵列信号处理中的协变异应用到语音增强中，对带噪语音信号的协变异系数矩阵进行特征值分解得到纯净语音信号的子空间。

Fixed detector data of Shenzhen is used to reveal time-varying rules of traffic flow parameters during workday, weekend and holiday as well as its fluctuation degree within 24 hours. Similarity coefficient and fluctuation coefficient are cited to show the covariation and fluctuation degree of traffic flow on different days.

以检测器数据为对象进行分析，揭示了交通流参数在工作日、周末和节假日三类时间的不同变化规律以及交通流参数在一天中的波动程度；引入相似系数和波动系数，研究了各天的交通流参数在时间轴上的变化趋势的相似程度以及各天之间的波动程度。

I use an example quoted by Hu Jiaqi:"It is reported that America separates the DNA of a kind of virus by making use of genetic technology and combines it with another kind of DNA. Finally, they get a kind of virulent biological agent called a "pyrotoxin". Someone discloses in private that 20 grams of such a kind of biological agent could result in the global death of 6 billion people due to infection."

我在这里例举胡家奇所引用过的例子："据报道，美国利用转基因技术，将一种病毒的DNA分离出来，与另外一种DNA进行结合，拼结成一种剧毒的"热毒素"生物战剂，且私下有人透露，这种生物战剂只需20克，就可以导致全球60亿人全部感染死亡。"

Waiting, for the queers and the coons and the Reds and the Jews.

等待着疯子和黑人还有红色共产主义者还有犹太人
