The paper presents how to use the technique of OLE and ARX of AutoCAD to build the geometrical model, the finite element model of the given structure visually and use the template and wizard to build the optimization model of it. During the iterative process of the optimization, the method of tracing visualization and interactive control is also provided. Some examples are given to show the appliance of visualization aided structural optimization. Finally, the work of systematic integration is carried out.

Because we mainly involve visual fields of medical science , have placed more contents on the development in the field of medical image of visual technology and argumentation used. Second part It is the visual technology knowledge, the generalization in such respects as the basic principle , basic functions, function store and three-dimensional animation technology to OpenGL ,etc. The realization of the system using OpenGL functions finish that three-dimension demonstration. The third part It is number value that calculate knowledge, three-dimension rebuild technology is it is it is it punish to fit to go on to need, the research of interpolator technology that cant leave, So this part has quoted the Hermite function principle , define cubic Hermite function to begin, calculate the differential coefficient among them draws cubic spline again.

由于我们主要是涉及医学可视化领域，所以将更多的内容放在了可视化技术在医学影像领域的发展与应用的论述；第二部分是可视化技术方面的知识，主要对 OpenGL 的基本原理、基本功能、函数库及三维动画技术等方面的概括，在系统实现时就是通过调用 OpenGL 函数库实现三维显示的；第三部分是数值计算方面的知识，三维重建技术需要进行拟合处理，离不开插值技术的研究，所以这一部分从埃尔米特函数原理开始讨论，引入三次埃尔米特函数，进一步计算时又引用三次样条函数。

Results There was strong correlation betneen ambeyopia and property of focus, other factors such as myopia, hypermetropia, and anisometropia didn′t have relation with degree of amblyopia until its affected the property of focus.

结果 弱视轻重程度最相关的因子是注视性质，而远视、近视程度、屈光参差程度及有无斜视与弱视相关程度被剔除，提示这些因素只有影响到注视性质时对弱视程度的影响才有差异。

Abstract］ objective to research the effect of synthesis curative for children amblyopia.methods 146 eyes of 82 children with age 4~14,did optometry after mydriasis by 1％ atropin, then did re-optometry and gave right glasses.

目的 探讨弱视综合训练治疗效果。方法 82例146眼4~14岁儿童，1％阿托品膏散瞳验光，经复验后配戴正确合适的眼镜，进行弱视综合训练（常规遮盖，精细视力训练，后像灯，cam视觉刺激仪，红光，多色光增色仪，光刷，视觉生理刺激，同视机，激光治疗仪）。

Happy inspect a net to think net still company such action, the network copyright market with disturb badly normal, operator of content of numerous Internet bar sees this news abandoned from happy the plan that inspects a net to buy this copyright, because this gives happy inspected a net to cause severe loss.
