提出了二次彩虹法测量高折射率玻璃微珠折射率的新方法，理论上分别用几何光学和衍射光学的方法分析了一次彩虹法和二次彩虹法测量玻璃微珠折射率的原理，给出了相应的数值结果，比较了两种测量方法各自的特点。

Based upon the assumptions of small deformation, the unretractility of the beam's axis and the inextensibility of the plate's neutral surface ("the method of geometrical deformation constraint"), we can obtain the geometrically nonlinearized formulae of the beams and plates. Accordingly, the "dynamic stiffening terms"would be naturally cooperated into the dynamic equations of flexible multibody system if combined with the linerization of kinematic parameters at the proper stage.

利用杆类柔性体轴线的不可伸缩性和板类柔性体在中面内的不可伸展性，并结合小变形的假设，从而可获得杆类和板类的几何非线性变形表达式；以此为基础，在适当阶段对运动学参量进行线性化处理，可确保"动力刚化项"在建立柔性多体系统动力学方程过程中自然地形成。

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.
