The article analysed the evolvement of the slop parameter from the 1970s to the 1980s and to 2000, we chose the slop parameter based on the clay nature in Long-gu mine.

Research on the comprehensive determination of activated sludge parameters and their application

The case indicates that elastic impedance inversion can obtain ideal inversion result and from the inverted impedance section we can extract lithologic parameters which can reflect lithology and fluid character.

This has to do with a variety of rock-electro parameters such as m, a, m, and b which are related to oil saturation calculation of the reservoir.

There are variant rocks in Junggar and Tarim basins,a lot of experiments have testified rock-electro parameters are very different in sandstone,conglomerate, carbonatite,volcanic rock.

Determination of rock mass parameters and application of roof bolting;

By the methods of micro-damage theory,the relations of rock mass parameters and rock parameters in experiments were obtained;it is considered that to make the micro-damage theory for determining the rock parameters possible only in condition that the crack density parameters are obtained reasonably.
