1)  drift response Hessian matrix

2)  hessian matrix

1.
The paper derived the formulas of drift response gradient and Hessian matrix of multi-storey and high-rise building structures under the ground motion based on the Newmark-method and developed the algorithm of drift response gradient and Hessian matrix of multi-storey and high-rise building structures.

4)  fuzzy-random correlation function matrix

1.
Considering the fuzzy-randomness of the structural physical parameters and geometric dimensions simultaneously, this paper develops fuzzy-random correlation function matrix of the displacement response in time domain, and then obtains the fuzzy-random mean square values of the displacement and stress in frequency domain.

5)  response matrix

1.
Research on groundwater management model and its application based on unit pulse saline intrusion response matrix;

2.
In view of demands of the optimum design on deep excavation(pit) dewatering under complicated hydrogeological condition,the pulse and response relation and principle between the state variable,and controlled variable in groundwater system as well as how to construct groundwater table response matrix are introduced.

3.
A method that fit the measured response matrix to the model response matrix is developed to calibrate the linear optics.

6)  displacement matrix

1.
Using the constraints of through settled point and alterable pole length and the application of displacement matrix method to the leader mechanism as a rigid-body guidance,this paper introduces the synthesis of carrying out the anticipative track and function generator and the synthesis method of function generator of alterable pole length-pendular hydraulic cylinder.

2.
To implement the guide of rigid body,the displacement matrix is used to synthesis of four joints planar linkage.

3.
Based on the articulated beam in Bridge Project,the paper adds up the unit loading effect on the displacement matrix on other beams,and the matrix realizes the calculation methods of the computer program.

 伊本·海赛木（约965～约1039）Ibn al Haytham     中世纪阿拉伯学者。又译为阿尔哈曾。曾简译为海桑。在光学、医学、天文学和数学方面都有重大贡献。11世纪初，埃及流行眼病，当时在开罗的天文中心工作的伊本·海赛木根据医师们的经验特别是通过他自己的一些有关反射、折射、暗室视觉等实验，仔细研究了人的视觉。在其名著《光学宝鉴》中，他否定了人眼对外发光的旧视觉观念及提出由物体发出光线锥而引起视觉的观点；他所提出的人眼结构和眼球内的3种透明体的名称沿用至今  ；他明确入射光与反射光共面及球面反射成像原理；他还讨论了光之折射和玻璃球的放大像的作用。除《光学宝鉴》外，他还有几何学著作及一些保留下来的手稿，其他均已散佚。
