Water waves travel in expanding circles, and air waves in expanding spheres.

水波是以不断扩大的圆圈来传播，而空气波是以不断扩大的球体来传播的。

However,in at early work of Dolan and Jackiw, after the analytic continuation ofthe imaginary time thermal propagator, the result was not the 2 × 2 matrix thermalpropagator in the real time formalisms, but only the 1-1 component of the matrix,which caused singularities like higher order δ function's.

然而在Dolan和Jackiw的工作中，由虚时热传播子解析延拓得到的结果不是实时方法中的二阶矩阵形式的热传播子，而只是其中的1-1矩阵元，从而会导致象高阶δ函数这样的奇异性，本文指出，这个结果是来源于一个隐含的假设，即认为实时方法的背景时空是一个明氏时空。

The media in the dissemination of psychology as an analytical tool is the development of patterns of television programs, television programs are planed through the use of different symbols ,dissemination of audience psychology and consumer demand analysis, the completion of the building programs patterns, consolidation of television programs consumer market.

以电视传播和媒介心理学作为分析工具是符合电视节目形态发展规律的，电视节目的策划人正是通过利用节目中不同的传播符号和对受众消费需求心理和消费行为的分析，完成对节目形态的建构，巩固电视节目的消费市场。

中国疾病预防控制中心Lijuan Zhang及其同事开展了一项研究，旨在确定在中国罹患HGA的首批病例的起源和传播的情况，以及确认该种疾病在人与人之间传播的首次发现。

In addition,the dispersion relation and delay characteristics of the coupled mode in two different YIG films are studied by numerical analogue in the range of inclination angle from 5° to 20°.

本文研究了在倾斜静磁场作用下，双层YIG薄膜波导结构中静磁体波的传播特性，得到了其色散的特征方程，计算了磁场倾角从5°到20°范围内双层波导结构中静磁体波传播的色散关系和延迟特性。

With method of radial tracing, path numbe ofmultipath and angle of incidence, times of reflection, attenuation, and delay werededuced based on the theory of stochastic.

根据随机过程的基本理论，采用射线追踪法，从电波散射和绕射原理，推导出高速移动台无线通信多径传播的径数、入射角、散射次数和衰减系数、多径传播路程和时延等的概率分布。

The lower-level (850 hPa) ISO pattern is char-acterized by an anticyclonic circulation over the area south of the Changjiang River, the South China Sea, and the Western Pacific, and a cyclonic circulation from the area north of the Changjiang River to Japan.

对逐年夏季的分析表明，无论当年东亚夏季风强与否，在所划分的几个东亚季风区所有涝的年份里，太平洋同一纬带上大气ISO向西传播都明显较强，而在这些区域绝大多数旱的年份里，相应的ISO向西传播明显较弱。

The linear theory of antisymmetric ducted gravity waves supported by mesospheric thermal duct is presented, propagation and evolution of gravity wave packets in thermal duct is also simulated by using a nonlinear two-dimensional model. Numerical results show that lower atmospheric wave disturbance can penetrate into the duct area and be trapped.
