Study on Dispersive Influencing Factors of Dispersive Soil in Western Jilin Based on Grey Correlation Degree Method BAO Shuochao1, a, WANG Qing1,b and BAO Xinhua2,c 1 College of Construction Engineering, Jilin University, Changchun, China 2College of Environment and Resources, Jilin University, Changchun, China abaoshuochao@126.com, bwangqing@jlu.edu.cn, cbaoxh@jlu.edu.cn Keywords: grey correlation degree; dispersive soil; water conservancy project; influencing factors Abstract.
Grey correlation is the basis of grey system, it is a kind of method which can describe and compare quantitatively variation and development trend of system [3], determine principal relation of factors in the system, locate the key factor effected desired value.
As two kinds of cementing material, organic and clay particle have the ability which increase the connection between soil particles, this ability can make the particles of soil swelled and dispersed.

Introduction SiC is a very attractive material for high-temperature, high-power and high-frequency devices.
However, because it is impossible to grow SixC1-x solid solutions with x near 0.5, bandgap engineering cannot be applied to SiC devices.
Heteroepitaxial growth of group-III nitrides on SiC makes it possible to utilize bandgap engineering in SiC-based devices.
Further reduction of the recombination current of emitter junction is the key to obtain high-performance GaN/SiC HBTs.
