For example, in Huizhize pluton, the DS mechanism produced only about 20% space for the present volume of the pluton, the regional TE contributed 19～32% space and MS, including stoping and material transfer processes, yielded another 38% space.

例如，在秦岭造山带核部最大的灰池子花岗岩体的定位中，主动膨胀机制开辟了20％的空间；区域构造扩展提供了19～32％的空间，岩浆侵吞机制提供了37％的空间。

The only way is to read the text of the city, and observe and experience the city space in order to understand the incidents in the city space and the utilization of the space. This causes human to re-recognize the residential city again and remind the collective memory of people to the city. People will further think about the relationship between human and city and reposition the own role in the city.

而唯有透过城市文本的阅读与城市空间的观察、体验，暸解城市空间里发生的活动事件与空间的使用情形，使人重新去认识自己居住的城市，以唤醒人对城市过往的集体记忆，进而思考人与城市之间的关系，并重新定位自己在城市中扮演的脚色。

To investigate the spatial-dependence of heterogeneity at multiple scales for a community, we selected a representative plot of 100 m×100 m in the mountainous evergreen and deciduous mixed broad-leaved forest in Sichuan, southwest China (102°50'E, 30°02'N).The location of every tree was mapped by compass, and all-scale analysis of spatial structure of forest community was conducted by the method of PCNM (principal coordinates of neighbor matrices).

为了解植物群落在多尺度下的空间变异规律及其对空间尺度的依赖，以川西南山地阔叶混交林为对象，在有代表性的地段设立100m×100m样地，采用传统的罗盘仪对树体的相对空间位置进行定位，运用主轴邻距法(principal coordinates of neighbor matrices， PCNM)对群落空间结构的多尺度（100m内）特征进行了研究。
