I heard the old man Sadecer to say,"his aunt Viola died like this ,she had been counting the feather laid on her bed which was used for marry,""comes here ,goes there" I said,I thought the old man was fool ,speaking without anybody,it is too quietly ,the sound of clock sound like loudly ,58 minutes passed ,I 'll get the 100 dollars after another two minutes ,I 'm weak and thirsty ,then,I heard the door open , when I heard a woman to cry ,it turned to be my wife Sarah"oh ,my God ,my God "I begined to pray for my wife not to come to me ,I couldn't threw any things to my wife ,even if a dish also or not ,ten seconds ,three ,two ,one !

摆过来，摆过去"我说，我觉得这个老头是个愚蠢的老人。没人说话。这里太安静了，钟声听起来似乎都很大。58分钟过去了。还差两分钟，一百美元就要是我的了。我的声音已经没力气了，嘴巴也干了。然后，我又听见门开了。一个女人的哭声传到我的耳朵时。那是我的妻子Sarah。"噢，天呐，天呐我开始祈祷，别让她接近我，我不能对我的妻子扔任何东西，即使是一个小盘子也不行。十秒，三、二、一！

Numerical Simulation of Flow Field in Pulsating Fluidized Bed Under special entry conditions, the CFD is used to simulate the three-dimension fluidized bed with different oscillation intensity and frequency in order to research the effect of sound oscillation on flow field in the fluidized bed. The results indicate that the sound oscillation can make the distribution of the flow field more uniform and can promote the heat and mass transfer.

脉动流化床流场模拟在特定的入口条件下，应用计算流体力学技术对三维流化床在不同振动强度、不同频率扰动作用下的流场进行模拟，得到声波扰动对流化床流场分布的影响，结果表明声波振动可以使流化床内的流场分布更加均匀，促进热质传递。

The other filiation of morden communication is sound communication, the purpose of sound communication is enable immediate、no error、no interrupt communication.

现代通信的另外一个分支就是语音通信，语音通信要达到的目的是能够实时地，无差错、无干扰地通信。

The lead plane both can show lively wave filmstrip and can broadcast gentle beautiful music or a little natural sound, for instance , sea wave , forest brook in rain, heartbeat sound having mother more.

Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.

在获取定性反演先验信息的基础上，提出了两阶段反演的方法：第一阶段，区分优质像元和非优质像元，合理确定像元声速的迭代初值；第二阶段，区别对待优质像元和非优质像元的约束权重，定量反演最终的速度分布。2个混凝土试件的模型试验表明，两阶段反演能有效抑制伪像，具有比常规的一阶段反演更好的缺陷识别效果。
