That is that information processing of neural networks is viewed as the composition of the two steps: field organization and field action, in which, field organization transformation converts input pattern into relevant structure representation, extracting the underlying architecture features and forms a architecture representation in action transformation space; The field action transformation converts the features representation into expected output. In strategies, we use the dual affine coordinates in dual flat manifold as way of representation of field organization system and field action system, which established a theoretical framework of analysis the coupling mechanism of information processing from the view of point of structure representation and model generation.

在具体人工神经网络结构描述的策略上，利用对偶流形空间上的对偶仿射坐标概念分别表示场组织变换系统和场反应变换系统，建立起从问题的结构表示和模型生成两种观点来分析信息处理的理论框架；分析了有监督和非监督学习人工神经网络模型在神经场变换机理下的形式化描述。

With the use of a robust error mapping function, an affine model-based target tracking algorithm is formulated, in which a quasi-Newton's iterative method is implemented in the optimization progress.

算法中使用的"由粗至精"计算策略以图像金字塔数据结构为基础，采用自顶向下的计算顺序，并在每层金字塔上结合对鲁棒性误差映射函数中控制参数所做的逐步降级处理，实现了逐步求精的计算目的。

This method represents the virtual objects in Euclidean space instead of in affine space, which is consistent with the popular graphics rendering tools such as OpenGL and is more common in practice. A new classification based local and global tracking strategy to match features between the reference image and the currently frame directly is presented, which enables the augmented reality system working effectively even under large changes of viewing angles. A novel affine coordinate system definition method based on a collection of feature points is also proposed, which makes the tracking method effective even when not all the reference points are detected during the whole process, as long as there are at least four pairs of reference points correspondences.

该方法以仿射变换为桥梁来建立欧氏空间下的摄像机坐标系与世界坐标系之间的变换关系，它与OpenGL等当前流行的图形渲染工具一致，具有更强的通用性；采用基于分类的自然特征匹配策略，能够在视角和视点发生大幅度变化情况下依然正常工作；提出基于特征点集合的仿射坐标系定义方法，使增强现实系统在最小配置下只需4点追踪成功即可完成注册，比需要6点的透视投影方法具有更好的健壮性和精确性。

First half of the year, international capital still is in with a kind enthusiastic condition bee afflux enters China, but as economic situation of second half of the year increasingly austere, the supply demand relations that invests a bound had happened to reverse sexual change, achieve congenial compose already apt is adopted more conservative the investment with discretion is politic.

在2008年的上半年，国际资本还在以一种狂热的状态蜂涌进入中国，但随着下半年经济形势日益严峻，投资界的供求关系已经发生了扭转性的变化，创投机构已倾向于采取更加保守和谨慎的投资策略。

Methods To summarize the clinical effects of 182 soft tissue expanders used in 80 patients in 3 aspects: the selection and embedment of the expander; the method of suture; and the strategy of expander affusion.

In this paper, proposed a evolution strategies to eeg source localization, which based on the agamogenesis natural selection of biology.

该文从无性生殖的生物在自然界中优胜劣汰的进化模式中得到启发，设计了基于进化策略算法来进行源定位。

Phenotypic plasticity and genetic differentiation are the two major strategies that alien invasive plants can adapt habitat heterogeneity.The polymorphism of invasive plants and the diversity of their dispersal way enable them occupying invaded habitat quickly,and dispersing with a far range.The breeding strategies that agamogenesis and amphigenesis can coexist and trade off according to the habitat and invasive stage can not only promote the invasive population erupted massively,but also directly affect the dispersal mechanism and regulate the genetic structure of the population.

表型可塑性和遗传分化是外来入侵植物对生境异质性的两种适应策略；散布体多态型和散布途径多种化，使外来入侵植物迅速占领入侵生境，并进行远距离扩散；无性生殖和有性生殖并存，并根据生境和入侵阶段权衡的繁育对策不仅使入侵种群大面积暴发成为可能，而且直接影响散布机制并对种群遗传结构具有调节作用。
