thermal abrasion,thermal etching

On this basis, it is discovered that a special effect, karst heat corrosion subsidence on the whole ground of the city caused ty the urban heat island effect on Guilin located in the special karst environment through combining th.

通过对Landsat热红外波段TM6、近红外波段TM5和可见光波段TM1的综合信息图像处理 ,结合丫吉村岩溶水文地质试验场土层下石灰岩溶蚀随气温变化数据以及 1987— 1996年 10年内桂林城市气温观测数据 ,发现城市热岛效应会对处于特殊岩溶地质环境中的桂林市造成一种特殊影响———城市地面整体岩溶热蚀沉降。

For prognosticating developing karst heat corrosion subsidence of the whole urban ground of Guilin, the study plan for setting up the dynamic model of the virtual prognostication for karst heat corrosion subsidence based on t -GIS has been put forward in this paper.

为对正在发展中的桂林城市地面整体性岩溶热蚀沉降开展定量预测 ,提出了建立基于t-GIS的桂林城市岩溶热蚀沉降虚拟预测系统的研究方案。

The effects of different thermal etching processes on the Scanning Electron Micrograph(SEM) and the characteristics and forming reasons of all kinds of microstructures were studied.
