The main conclusions from the works presented in this thesis can be as this: for the Galactic OH 1612MHz masers, the radiative pumping mechanism coexists with other mechanisms while some other unresolved problems need to be solved after the launch of more advanced space infrared spectrometer and the more reliable identification of the evolutionary status of the maser bearing infrared sources;the asymmetrical 53.3μm absorption line profile could become a powerful tool to assist us to observationally discriminate the radiative pumping mechanism from other pumping mechanisms in the OH masers.This is the English version of my PhD thesis.

通过本论文的研究工作，我们可以得到这样的结论：在银河系内的OH 1612MHz脉泽中，辐射抽运机制与其它抽运机制并存，而还有一些未解决的问题需要等待更先进的空间红外光谱观测设备的使用并与天体类型证认工作相配合加以解决；不对称的53.3微米吸收线轮廓特征有可能成为帮助我们从观测上对OH脉泽的辐射抽运机制加以鉴别的有力工具。

Lastly, evolutionary biology studies the origins and development of the human nervous system and, in as much as this is the basis of the mind, also describes the ontogenetic and phylogenetic development of mental phenomena beginning from their most primitive stages.

Notable findings include a theory to explain the extended ontogenetic and brain development periods of big-brained organisms, fMRI research on the neural correlates of romantic attraction, an evolutionary view of sex differences in spatial cognition, a theory of language evolution that draws on recent research on mirror neurons, and evidence for a rudimentary theory of mind in nonhuman primates.

值得注意的结论包括一个理论解释大打死的生物体的被延长的ontogenetic 和大脑开发周期， fMRI对浪漫的吸引力的神经的相关数的研究，性空间认知的差别的进化的意见，一个动用新近的对镜神经元的研究的语言演化，以及一个在非人类的大主教里的记忆的初步的理论的证据的理论。

It is true that human ontogeny need not be a recapitulation of the evolutionary events that led up to the formation of language capacity.

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。
