So, in this paper, a circular cavity witha large radius is used to replace the straight boundary of thehalf space, then the half space problem can be changed tothe scattering problem of two circular cavities to the steadyincident P-wave . Having the aid of the mature cylinderfunction theory, the general solutions of the wave functionscan be given, and an infinite linear algebraic equations ofthe unknown coefficients in the wave functions can be gottenwith the boundary conditions and the Fourier complex seriesexpansion technology, the infinite linear algebraic equationscan be approximately solved by the finite trunction withsatisfying some definite precision, at the basis of thissolution of the equation, the variations and the lay-outs ofthe DSCF at the circular cavity boundary vs. the differentincident angles, the different embedded depths of thecircular cavity as well as the different dimensionless wavenumber of the incident P-wave.

为此，本文采用一个半径很大的圆孔来代替半空间的直边界，将该半空间问题转化为一无限大空间中两个圆孔对稳态P波的共同散射问题，借助于成熟的柱函数理论，通过写出问题波函数的一般形式解，利用问题的边界条件，并采用复数傅立叶级数展开技术将其化为一个仅包含问题波函数中未知系数的一无穷线性代数方程组，在满足一定计算精度的前提下，通过有限项截断进行近似求解，进而讨论了圆孔边界处的动应力集中系数随不同入射角、不同的圆孔掩埋深度、入射波的不同无量纲波数以及介质的泊松比变化和分布情况。

This paper takes the classifier "Chuan" as a case study to explore the issue of classifier teaching from the angles of Chinese characters, language , cognition and culture, and proposes that TCFL teachers should follow human's cognitive mechanism advancing from easy to difficult and from concrete to abstract to carry out a phased teaching of Chinese classifiers stressing varyingly on their grammar, semantic and pragmatic features by adopting comprehensive teaching methods.

文章以量词"串"为例，从文字、语言、认知和文化等角度对量词教学展开探索，认为教师应遵循人类从易到难，从具象到抽象的认知规律，综合运用多种教学方法对量词的语法、语义和语用开展有所侧重的阶段性教学。

Coherent interference can be suppressed by the EMCMVB efficiently. The EMCMVB first gets the modified signal subspace by using the estimated arrival angles of coherent interferers and the eigenstructure of the correlation matrix, and then projects the MCMVB weight vector onto the modified signal subspace.

EMCMVB是利用估计得到的相干干扰方向和阵列信号相关矩阵特征分解来得到修改的信号子空间，再把多约束最小方差波束形成器的权矢量向修改的信号子空间投影来得出新的权矢量。

The simulation results show that there are many factors to influence the reverberation, each of them has different contribution to the reverberation, and the angles configurations and the characters of interface have main function, and the effect of the change of sound velocity on reverberation can be ignored.

模型仿真结果表明，影响双基地声纳混响的因素众多，每个因素在对双基地混响的贡献是不一样的，双基地角度的配置和界面性质变化对混响的影响很大，而声速的变化对混响的影响可以忽略不计。

These mountain vermilion shape Linglong Kit Kat, remove cloth for King, different angles as there are different types.

这些朱红色的山体造型玲珑奇巧，移布换景，不同的角度有不同的象型。
