声的传播 meaning in English
sonic propagation
Examples
- In acoustics he studied the propagation of sound and musical consonance and dissonance .
在声学中，他研究了声的传播和音乐的和谐与不和谐。 - A gas flow in such a scenario will affect the sound field distribution , the sound speed and the sound propagation mode inside the muffler
此种状态的气流将会影响消声器内部的声场分布、声速、声的传播规律等，特别是气流速度影响更大。 - This paper is devoted to nonlinear approximation , namely , m - term approximtion of anisotropic smooth periodic functions . nonlinear approximation is the important part of approximation the - ory . it means that the approximants do not come from linear spaces but rather from nonlinear manifolds . the advantages of nonlinear approximation show that one can achieve a given accuracy of approximation while assuming less smoothness on the function in the nonlinear case than is necessary in the corresponding linear approximation . nonlinear approximation is used significantly in many applications , such as image processing , noise removal and the solution of operation equations and so on
非线性逼近与线性逼近最大的区别在于所用的逼近子空间不是固定的，而是依赖于被逼近的函数其主要优点是对光滑度较低的函数仍可以得到较高的估计阶。随着小波和样条的广泛使用非线性( m项)逼近成为较热门的话题，它在图象处理，声的传播，算子方程的求解等方面都有很多应用。
