This can be similar to the use of Lenz's law to solutions of space-time than the release, when the objects move in time and space, the space-time market will hinder movement of objects inside.

这可以类似的运用楞次时空定律来解比释，当物体在时空中移动时，时空场会阻碍物体在里面运动。

After analyzing the merit and lack of 9I model, the main idea is proposed: to distill some basic topological relations from 9I model, of which the composite topological relations of complex objects are made up. In detail, the composite topological relationships between region and region, line and line, line and region are particularly discussed;(2)Analyze the characteristics and inner relations of cadastral features. According to the expressional model of complex topological relations, the author discovers the possible topological relations between parcels, parcel lines and parcel points. In addition, sum up the general topological relationship rules of cadastral data.(3) Then the topological relations model is extended to the spatio-temporal data. Time in cadastral database and change semantic are discussed. It's redefined that spatio-temporal topological relations is composed of time, location, status and event relation. Spatio-temporal topological relationships can be represented by extended 4I model. Taking cadastral parcels as example, there are different possible spatio-temporal topological relationships between parcels when they are extended, shrunken, split, merged or others. Thus, some deductions are drawn that, for example, if parcels have be coexisting for some time they are impossible to be overlapped. Furthermore, the parents of parcels alternated and their possible change types can be detected by their spatio-temporal topological relationships.(4) Before carrying out the experiment, the calculation method must be designed.

At the every relative momentary point of time time-space, the situation of difference spatial measurement of cosmic gravitation exceed cosmic space-energy follow the rise and fall of quantum spatial measurement, at original cosmic time-space set out, from 0 come to do not exceed the 1/2 spatial measurement of cosmic time-space, not smaller the 1/4 spatial measurement of cosmic time-space, come to do not symmetrically gradually belong to stabilization thus at reductively fluctuate, not can reversely strides across reach the stable state of 1/3 spatial measurement cosmic time-space maintain unchanging.

The first chapter analyzes an aesthetic effect caused by the spatialization of narrative time and the misplacement、interdynamics between historical space—time and narrative space—time.

第一章从时空角度切入，分析了历史时空与叙述时空之间种种错位、互动以及时间的空间化以后产生的审美效果。

Or perhaps the time-traveler never returns at all: The dead butterfly does not beat its wings, causing a minute impact on the weather which, through the magic of chaos theory, ramifies down the ages, eventually leading a storm to make landfall on one rather than another shore, killing the time traveler's great-grandfather, and thus leading to the time traveler's own disappearance in a puff of logic.

或者，跨时空旅行者也许根本无法返回：死去的蝴蝶不能拍动其羽翼，以引起天气的微小影响。其通过混沌理论的魔力分开时空，最终导致暴风雨在陆地的一侧而不是另一海岸登陆，杀害了跨时空旅行者的曾祖父，这样导致跨时空旅行者在逻辑的夸张中消失。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
