Also the response amplitude will be changed with the initial conditions due to the nonlinear properties of the cables.Taking the bending stiffness, cable sag and cable inclination into consideration, the space vibration control of the cables using the visco-elastic dampers in cable-stayed bridges is investigated by joining the center difference method and the state space strategy. Both the maximum modal damping ration and the optimal damper size are obtained, then the practical suggestions are proposed for the design of the dampers. The space nonlinear vibration equations of the cable-damper system are derived, and anew hybrid method for solving the cable-damper system is presented by combing the Newmark method and Pseudo-force technology. According to the known properties of the cable-damper system, the nonlinear transient responses are analyzed under all kinds of excitations. Based on the transient response, the control effectiveness of the visco-elastic dampers is further demonstrated.

综合考虑了拉索抗弯刚度、垂度的影响，研究了粘弹性阻尼器对斜拉桥拉索的空间振动控制，联合中心差分方法及状态空间法，得出了拉索面内、外振动各阶模态可能达到的最大阻尼比及相应的最优阻尼器系数，并对斜拉桥拉索的阻尼器设计提出了参考建议：考虑拉索抗弯刚度、垂度及几何非线性，导出了索-阻尼器系统的空间振动非线性方程组，结合Newmark方法及伪力(Pseudo-Force)方法，创新地提出了求解非线性方程组的杂交方法，根据拉索-阻尼器系统的阻尼特性，在各种荷载作用下，对索-阻尼器系统的非线性瞬态振动响应进行了研究，从系统响应的角度更加直接地验证了阻尼器的控制效果。

On the basis of the previous results and according to the central composite experimental design principles,the method of response surface method with 3 factors and 3 levels was adopted.then the factors influencing the technological parameters were determined by means of regression analysis.response surface and contour were finally graphed with the extraction rate as the response value.resultsthe optimum conditions of lycium barbarum polysaccharides extraction were as follows:the ratio of material to solvent of 1∶32,extraction temperature of 84℃ and extraction time of 2.3 h,one time extraction.conclusionthe yield of lycium barbarum polysaccharides is 11.10% under the optimum conditions.

方法在单因素实验基础上选取实验因素与水平，根据中心组合（box-benhnken）实验设计原理采用3因素水平的响应面分析法，依据回归分析确定各工艺条件的影响因子，以多糖提取率为响应值作响应面和等高线。结果在分析各个因素的显著性和交互作用后，得出枸杞多糖水浸提的最佳工艺条件为：料液比1∶32；浸提温度84℃；浸提时间2.3h；浸提1次。结论在最佳工艺条件下，枸杞多糖的实际提取率可达11.10%。

During the 1980s two parallel regroupment efforts emerged, one centered around the Communist Party of the Philippines, which gave birth to the ICMLPO, and one that birthed the Revolutionary Internationalist Movement, which the Shining Path communist guerrilla group and the Revolutionary Communist Party USA played a leading role in forming.

在1980年代出现了两个平行的重组运动，一个以菲律宾共产党为中心，创建了ICMLPO（国际马列主义政党与组织大会）；另一个创建了RIM，光辉道路共产主义游击组织和美国革命共产党在创建中起了领导作用。

Gabor-ring is often used in texture feature extraction, but it is based on the assumption that texture is narrowband signal and can not applied to most actual textured images that have more than one center frequency in power spectrum. To overcome the limitation of existing method, an improved method is proposed. According to this method, Gabor filters are constructed in accordance with the spectrum feature vector of texture, and a relaxation parameter is used to determine the effect of difference filters so as to integrate the frequencies and phases into the process of extraction.

Gabor环（即在频率域成环形分布的Gabor滤波器组）常被用于提取图像纹理特征，但它是以"纹理是窄带信号"为基础的，实际的纹理图像并不能很好地满足"窄带信号"的假设，用一个中心频率来描述一种纹理对能量集中在多个频率点的纹理图像往往不能取得理想的效果，而根据频谱特征值向量构造Gabor环的改进方法，通过松弛因子的加入改变不同滤波器的作用强度，综合考虑了多频率多相位对纹理特征提取的影响。
