The micro actuator's static state characteristic by static electric force is analyzed in detail. The steady balance position's existing condition is educed while the moving pole move with linear displacement, and the relationship between driving voltage and the moving pole's line displacement is presented. The adsorption voltage by which the moving pole is adsorbed to fixed pole is exported. The resolution method of the pole cornual displacement's static state characteristic is opened out.

The characteristic information of denudation and cumuli area, excavation and transport area, and slope area is highlighted in the first principal components. The information of higher and lower vegetation-cover area is highlighted in the second principal component. Results show that the contribution rate of two principal components in the front achieves 97.16%. And object feature was classified by using characteristic of disturbance and vegetation.

对研究区TM影像进行主成分分析，剥离堆垫区、采煤运煤区和边坡区等反映矿区扰动特征的信息主要由第1主成分反映，植被低覆盖区和高覆盖区等反映矿区植被覆盖特征的信息主要由第2主成分反映，两个主成分的贡献率达到97.16％，并利用扰动特征和植被特征对研究区地物进行了分类。

The results showed that the spatial characteristic of spectra on the opencast coal mine varied with land type area distribution, and landscape pattern. The first and second principal components of the TM images had obvious spatial characteristic, i.e., the first principal component highlighted the characters of excavation and transportation area, slope area, and cumuli and stripping area, while the second principal component highlighted the information of higher and lower vegetation-cover area.

结果表明：由于露天矿区土地扰动下土地类型、面积分布及其景观格局的不同，其遥感影像的光谱空间特征也不相同，但前2个主成分构成的空间特征结构十分明显，第1主成分主要表示采煤运煤区、边坡区以及剥离堆垫区的特征信息，第2主成分主要表示植被高覆盖区及植被低覆盖区的特征信息。
