模糊理论界目前对该理论的研究还有待加深，但这一理论已渗透到翻译学科、修辞理论研究、语音学、以及方言研究等领域之中，具有很大的发展潜力，也是论文作者在以后的学习、工作中重点关注的领域之一。

It turns the problem of differential game into the problem of maneuver identification and optimization control based on neural networks.

阐述了微分对策理论在实际应用中存在的问题，并从动态冲突的实际过程出发，将神经网络理论与分层式智能控制理论相结合，来模型化微分对策问题。

Due to the numerical aperture of DVD pickup is large, and the characteristic size is small, the error of scalar diffraction theory is very large. The in-depth research work on vector diffraction of optical disc was carried out. The optical disk model was analyzed use the rigorous coupled wave theory, and some significative conclusion was obtained. These conclusions can use for guidance of scheme designing of optical pickup.

针对DVD读取头光学系统数值孔径大，光盘特征尺寸小，标量衍射理论误差大等缺点，采用矢量衍射理论对光盘的衍射进行了深入的研究，首次在光学读取头领域中将耦合波理论应用到光盘的衍射分析中，得到了一些有意义的结果，这些结果可以用来指导光学读取头方案的设计。

According to the theory of flow diffusion and convection, three-dimensional state equation of radon field is established for constant and variable diffusion coefficient and convection rate. The numerical solutions for different coefficient and different boundary conditions are obtained for two models of radon field which have respectively source in the side and inside of collapse column.
