This text is based on the work that analyse the problem having emerged about large-scale economic affordable residential district of city at the moment, in instance of the patterns in Xi'an. Through investigating living circumstances and building present situation, there are lots of requirement for economic affordable housing in Xi'an. As large requirement for premise, the question about choosing location large-scale economic affordable residential district in city is researched. As time as, it should be refer to the problem which were founded in others cities, then summarize a correct choosing location model for the practical situation, it could determent the location of large-scale economic affordable residential district of Xi'an.

The results show that the microstructure of ventra1 scale for python was composed of micro-convex and plank structure that was periodically arranged, it was mensurable and could be described by 9 characteristic parameters. Its surface was different in their forward and backward lean angle. The frictional coefficient of the ventra1 scale had closely relationship with moving direction, it decreased with the increasing load. The value of the frictional coefficient was about 0.07. The frictional coefficient while python moved backward and laterally were equal, and that was 33% more than that moved ahead. The frictional force of the ventra1 scale surface was caused by mechanical tooth function of micro-convex, acting intermolecular force and material's elastic hysteresis. The difference of forward and behind bevel for micro-convex was the anisotropy reason of frictional force.

结果表明：腹鳞表面的微观结构由指状微突体和板结构部分周期排列而成，其结构可用9个特征参数定量描述；腹鳞表面摩擦力由分子作用力、表面微突体的犁沟力、楔形作用力以及材料弹性滞后共同引起；腹鳞表面的摩擦系数在0.07左右并与运动方向有关，摩擦系数随载荷增加而减小；后向运动及左、右侧向运动时摩擦系数基本相等，比前向运动时高33%左右；腹鳞表面微突体不同方向上倾斜角度的差异是引起摩擦各向异性的主要原因。

If average values before or after catastrophe point when the pressure at both ends reduces exceed the threshold value, judging that there is leak and positioning: calculating approximate wavelet transformation coefficient of pressure data at both ends, initializing searching interval, calculating a signal time delay value corresponding to approximate wavelet transformation coefficient in the searching interval from maximal scale N; converting the time delay value under scale N to that under N-1 by geometric proportion relation; updating the searching interval, repeating above processes until the scale is 0 and positioning based on the time delay value.

若两端压力下降突变点前后的均值变化均超过阈值，判定有泄漏并进行定位：计算两端压力数据的近似小波变换系数，初始化搜索区间，从最大尺度N开始在搜索区间内计算对应近似小波变换系数的信号时延值，利用等比关系将尺度N下的时延估计值转换为N-1下时延估计值，以该值更新搜索区间，重复以上过程至尺度为0，以此时延估计值进行定位。

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。
