This theory emerged from those philosophical and logical inquires Russell made in his early stage, when Russell use logical analysis to solve the semantics problem his meaning theory suffered. The foundation of the theory of descriptions is a theory of meaning, as this thesis presents, and its central notion includes two syntax rules. Based on the first order predicates calculus, this theory seems successfully solve some notable semantics problems and then assures Russell's denotation theory.

本文认为，摹状词理论有深刻的哲学渊源，它脱胎于罗素早期的哲学和逻辑研究，直接缘起于罗素想要利用逻辑的分析方法去解决意义指谓论所面临的语义学难题；摹状词理论的基础是它的意义理论，核心是两个句法规则，它基于带等词的一阶谓词演算成功地解决了一些著名的语义学难题，维护了直观的指谓论，从而产生了巨大而深刻的哲学影响。

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.
