Apollo was the sun-god in the ancient Greece.His another name is Phoebus,which means "rosiness" and "effulgent".So,wealso named Apollo as the rosiness-god .We couldn't find gloominess around Apollo ,and he never told a lie and always was on the up-and-up so that he also was called the gospel-god .

阿波罗是古希腊神话中的太阳神，阿波罗又名福波斯，意思是"光明"、"光辉灿烂"，因此也称啊波罗为光明之神，在阿波罗身上找不到黑暗，他从不说慌、光明磊落，所以他也称真理之神。

Moreover, during the radar signal generation, static and dynamic characters of backscattering coefficient are set up, and time sampling of each clutter unit is computed with voltage character and power spectrum character, and the sampling signals are added in every distance gate to output time series. In addition, noise is modeled with a function of Gaussian stochastic process.

指出了常负压力波波速定位方法的局限性，并采用改进的负压力波定位技术，将管道内的负压力波速公式采用复化辛普森公式进行了改造。

In comparison to scalar wavelets, multiwavelets simutaneously have several advantages such as compactsupport, orthogonality symmetry and so on, which are known to be important in signal processing. Thus, multiwavelets offer the possibility of superior performance for image processing applications.

与单小波相比较，多小波同时具备诸如紧支性、正交性、对称性等诸多在信号处理中非常重要的良好性质；这决定了多小波是一种优于单小波的信号处理技术。

In addition, Snell's law is applied, and traveltimes of waves from neighboring nodes are considered at the same time to determine the effective propagation area of the current secondary source.
