做声

This thesis introduces the research history of sonoluminescence, the properties and equipments of single-bubble sonoluminescence and the factors affecting the amount of light emission. Based on the experimental realization of SBSL, the experiment in this thesis is to confirm the coherence between the emitting frequency and the driving cycle of SL. Under this feature ,we established the programme of the experiment that measure the angular correlations in SBSL , built the experimental devices and conducted initial measurements .Then we got the conclusion that there is a presence of non-spherical symmetry in the process of SBSL .

本文介绍了声致发光的发展历史，对单泡发光的特性和实现声致发光的设备进行了描述，对影响发光强度的要素做了概述；并在实现单泡声致发光的基础上通过实验验证了单泡声致发光的发光频率与驱动超声频率具有一致性的特点，根据这一特点确立了声致发光角分布测量的实验方案，建立了实验装置，并进行了初步测量，得到在声致发光的过程中存在着非球形对称状态的结论。

Based on the simple global noise source, take the noise which is cared by people into account. Get the sound pressure level after processing the noise sources sound pressure. Educe the allowable value of the upper limit, through linking to the sound pressure level which is permitted. Taking the value into the reliability modals established before, found the diplex integral mathematics modals that is restricted.

考虑约束因素的影响，引入人们所关心的噪声，以结构简单的球形声源为基础，在对声源声压做了相对处理后，得到其声压级，结合许用声压级指标，求得许用频率上限值，将该值代入已建立的防共振模糊可靠度模型，建立有约束防共振模糊可靠度计算的双重积分数学模型。

He's had it out for me since the day I got here. Sara doesn't respond; she simply preps his arm for the shot.

但 Sara 并不做声，她只是在 Michael 的手臂上找寻注射位置，做好打针前的准备。

And many rebuked him, telling him to be silent.

有许多人责备他，不许他做声。

White-hot thrill sizzled from his chest and socked into his head.

白热的震颤从他的胸嘶嘶做声而且重击进入他的头之内。

His quick-witted sister only needed to observe twice that the armchair stood by the window; after that whenever she had tidied the room she always pushed the chair back to the same place at the window and even left the inner casements open.

默不做声、几乎下意识地交换着会意的目光，他们想到，现在已经到了也为她找一个如意郎君的时候了。当到达目的地时，女儿第一个站起来并舒展她那富有青春魅力的身体时，他们觉得这犹如是对他们新的梦想和良好意愿的一种确认。

But what surprised me most was to see at the back of the room, on the benches which were usually empty, some people from the village sitting, as silent as we were: old Hauser with his three-cornered hat, the ex-mayor, the ex-postman, and others besides.

但是，最使我吃惊的是，看到讲堂面，那些大凡空着的凳子上，坐着少许跟我们相同默不做声的村里的人，有头戴三角帽的奥泽尔白叟，有前任镇长，有曩昔的邮递员，别的还有别的人。

She was really making me angry,but i bit my tongue

他真让我生气，但我忍着不做声。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.

他拔下桅杆，把帆卷起，系住。
