最后得出以下结论：(1)径向纹理不通直的试件比通直的声发射撞击数要多，而且增加的趋势较快，但是在试件断裂前，声发射撞击数相差不大。

Flyball is a dog sport in which teams of dogs race against each other from a start/finish line, over a line of hurdles, to a box that releases a tennis ball to be caught when the dog presses the spring loaded pad, then back to their handlers while carrying the ball.

接飞球比赛是一项犬运动类比赛，比赛中各参赛小组之间决胜于起点/终点线，每只参赛犬要跨越一系列障碍到达一个发出网球的盒子，按下发射器后接住所发射出的球，然后将球带到指导手处。

The problem considered in this paper contains absorbing-emitting medium, absorption and emission of radiation not only exist on boundary of the system, but exist in the whole space fulled of medium, variation of temperature, pressure, density, compusure and property with coordinates must be considered in computation, so computation in this paper is based on three dimensional flow field.

本文所计算的问题包含吸收-发射性介质，能量的吸收和发射不仅发生在系统的边界上，而且还发生在充满介质的全部空间，在计算中要考虑介质中各点的温度、压力、浓度、成份以及物性在空间上的变化，因此本文的计算是根据三维流场计算的数据进行的。

The spatial distribution is anisotropic and symmetric. Soft x ray emission is far more intense than that from clusters and is mainly line spectra although there are some continuum spectra.

发射的软X射线强度远远高于团簇靶，此时的X射线发射主要由线谱组成，集中在lO-20nm范围，最高离化态可达0〓，同时叠加了稍弱的连续谱。

After this text introduced and will imitate the audio frequency signal processing as numerical signal after red shoot outside, the numerical signal that will receive again solution adjust after the audio frequency power enlarger enlarge restore in order to imitate the speech signal, shot the electric circuit outside analyzed to design the audio frequency signal before collecting the electric circuit, signal placed the big electric circuit, frequency to make the electric circuit, red, red circumscribed to accept the electric circuit,, frequency the solution adjusted the electric circuit and audio frequencies to enlarge the electric circuit etc.

本文介绍了将模拟音频信号处理为数字信号后经红外发射，再将接收到的数字信号解调后经音频功率放大器放大后还原为模拟语音信号，在分析设计了音频信号采集电路、信号前置放大电路、频率调制电路、红外发射电路、红外接收电路、、频率解调电路以及音频放大电路等各组成部分。

A low complexity detection scheme for the MIMO system with distributed transmit antennas is presented. Based on a Sorted CHolesky Decomposition, the additive gaussian color noise after match filter is whitened; The detection sequence according to the post signal noise ratio is reordered, and the risk of error propagation is degraded. The whole algorithm only requires one matrix inverse.

摘要针对发射天线分布的MIMO信号，基于排序的乔列斯基分解过程(Sorted CHolesky Decomposition，SCHD)，将匹配滤波后的加性高斯色噪声转化成加性高斯白噪声，根据后验信噪比对发射信号检测顺序进行重排，降低了误差传播的影响，该算法仅需一次矩阵求逆操作。

For atmosphere optical communications, which transmits laser beam through atmosphere, atmospheric induced fades of the beacon signal can vary significantly with atmosphere characters.

对於大气光通信来说，发射光束要通过大气，但由於大气的种种特性会引起发射信号的衰减，而且衰减作用非常显著。
