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。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
