与帐篷映射相比，该方案所采用的离散耦合帐篷时空混沌模型避免了有限精度实现产生的短周期行为，产生的时间序列近似服从均匀分布，具有更为理想的扩散与混乱特性。

As the basement to integrate multi-scale spatiotemporal data, the object evolution model can retain the characteristic of the data with different temporal-scale or different spatial-scale, and reflect the temporal changes especially the heteromorphic changes, and the causalities within the evolving process.

本文通过对时空对象变化过程的分析，指出对象进化的结果不仅是特征的变化，还包括机制的变化，其直接动力是对象行为，其根本原因是其内在机制，时空事件起着对象间信息通道的作用，据此提出对象进化模型，该模型可作为多尺度时空数据集成的结构性基础，在反映时空现象的演变过程，特别是异构演变过程，以及在这个过程中产生的因果关系的同时，还可以保留时空数据的不同时间尺度和空间尺度特点，从而达到增加时空数据库的信息量的目的。

Both qBrn-2 and Brn-2 were widely expressed in ventricular zones of developing neural tube including forebrain, midbrain, hindbrain and spinal cord, and showed a spatiotemporal change.

在胚胎发育中，qBrn-2和Brn-2都在整个神经管的室管区有广泛的表达，在特定发育时间里存在一定的分布差异。

In Chapter 4, we investigate the influence of a localized inhomogeneity on spatiotemporal chaotic state in an excitable reaction-diffusion system.

在第4章中，我们研究了可激发系统中，在螺旋波湍流态中引入两种属性不同的局部缺陷后，波斑图的选择。

Under the condition of intermit flood, the shallow groundwaters in different distances from riverway appear marked spatiotemporal dynamic changing rules and different responds.

在丧失河水对河道两侧地下水补给功能的前提下，距河岸不同距离的浅层地下水表现出不同的动态变化特征，并且在间歇性通水时发生不同响应变化。

In a word, these results indicate that there were no any difference of spatiotemporal cortical activation patterns underlying the early stage of insight problem solving between Aha logogriphs and No-aha logogriphs. In the process of activating heuristic information and then hastening the onset of insight, LPFC/ACC played an important role, which may be associated with the breaking of mental set successfully and the forming of novel associations in insight. The "Aha" feeling mainly provoked the PCC brain region in the solving the logogriph at last.

综合实验6与实验7的结果，我们认为，在字谜解决的早期，"有顿悟"与"无顿悟"字谜所诱发的脑电并没有明显的差异，原型激活可能主要发生在字谜解决的1400 ms左右，字谜的成功解决在1400-2000 ms内导致了左侧额中回／扣带前回的更强激活，这可能与原型激活以后，被试利用启发信息，突破思维定势，形成新异联系的认知过程有关；随后在2000-2500 ms内，字谜的成功解决则诱发了强烈的情绪体验，导致了扣带后回的明显激活。

Based on complete analysis of data about mountain torrent disaster and precipitation in Inner Mongolia in recent 50 years,the spatiotemporal distribution characteristic,periodic change regularity and influence factors for mountain torrent disaster in Inner Mongolia were obtained.

在全面系统地统计分析近50年的内蒙古山洪灾害和降水资料的基础上，得出了内蒙古山洪灾害发生的时空分布特征周期变化规律和影响因子。

In part two, the optical spatiotemporal pattern in ring optic cavity is investigated. Using delay feedback with spatial perturbation method, the system shows roll, square, hexagon, homocentric circle,"honeycomb"and"snowflower" pattern with different spatial perturbation functions. Different patterns can be coexist and compete each other with the same perturbation function, which is the new character of this optical system with delay feedback.

第二部分，利用延时反馈的空间微扰方法研究了环形腔中二能级介质的光学时空斑图的控制，在不同的微扰函数作用下，出现了滚筒状、四方形、六角形、蜂窝状、同心圆以及"雪花"状等不同的斑图，并且在相同的微扰函数下出现了不同斑图之间的竞争，这种竞争是我们发现的这一具有空间微扰的延时反馈非线性光学系统光学斑图的新特征。

In accordance with this characteristics, moving objects can be effectively extracted with local auto-adaptive threshold, and the trajectory of moving object can be gotten by applying projective transformation from spatiotemporal space to geography space.

针对该特点，运用逐点灰度均值将背景与运动点目标分离，并根据投影关系将目标投影到二维空间，获得直观的目标运动轨迹。
