At meso-scale level, the digital image processing method is used as a measurement tool to construct a digital representation for the distribution and the shape of aggregates in concrete; and at micro-scale level, statistical method is used to describe the inhomogeneity of component materials.

First,the crack initiation and expansion processes were divided into three phases: micro-scale thinness sight crack,CT scale crack,and macroscopic crack.

Ecological health assessment at the landscape scale based on RS and GIS,A case study from the New District of a Bay-type city;

Regional ecological security on landscape scale;

By using Landsat TM satellite images and combined with field investigation,the information of farmland boundaries in upper Minjiang River reaches was derived,and the edge effect of forestland-farmland boundary at landscape scale was investigated.

In this paper,based on the combination scale of the different catalytic active sites,the integrated system,which is composed of several catalytic reactions,is divided into three sub-systems:nano-scale,micro-scale and macro-scale.

The elasto-plastic damage and failure problem of mode I crack was studied at macro-scale level and meso-scale level respectively.

First,a high precision meso scale machine tool system was developed for meso machining research.

01 to 1mm known as meso scale.
