As the special soil
turfy soil and peat soil in China contained some similar properties with high void ratio
high water content
high organic content
etc. But turfy soil also had properties which difference from peat soil. In this paper
based on the formation of the cause and geological environment and geomorphologic characteristics of geological in the quaternary
took the typical and widespread turfy soil and peat soil regions for example
systematically discussed the material composition and macroscopic and microcosmic structural features
put further research on the physical chemistry mechanical characteristics. Then the come to the conclusion that the essential reason for difference between turfy soil and peat soil were decomposition degree and organic content. The result that worse engineering properties such as higher the moisture content
porosity
compressibility
internal cohesion and the lower specific weight
consolidation coefficient and permeability were due to the lower decomposition degree and higher organic content of turfy soil than peat soil. It can provide reference to the practical projects of turfy soil to distinguish peat soil according to this characteristic. (2012) Trans Tech Publications.

Space optical remote sensor is very important in many fields of science and military significance. It is widely applied. Space optical remote sensor design and manufacturing require precision and stability. Focusing mechanics is an important component of remote sensors. Focusing mechanics can guarantee the stability of the entire mechanics focusing accuracy
therefore the stability of research focusing mechanics is very important. In order to guarantee the space optics remote sensor focusing mechanics the stability
takes steps the space optics remote sensor focusing organization mechanics characteristic analysis from the classics contact theory. This article uses international general non-linear finite element analysis software ABAQUS to carry on mechanics characteristic analysis to the space optics remote sensor focusing mechanics. First acts according to the focusing mechanics unique feature
carries on the finite element to the structural model the grid division
the material attribute disposition and the boundary condition indeed grades. Then establishment contact non-linear finite element model
and to focusing organization finite element model infliction unit action. Like this contacts the result and the equivalent static analysis result which the nonlinear analysis obtains carries on the contrast and the analysis. This article last count result modality is 90HZ
satisfies the space optics remote sensor structure overall modality to request to be bigger than 50HZ.This article when carries on the dynamic analysis
extracts the structure kinetic energy and the acceleration curve. In the dynamic analysis obtained transient response analysis modality 70.5Hz
this also is bigger than 50HZ. The dynamic analysis indicated the structure dynamic stability has the distinct enhancement
has provided certain foundation for the space optics remote sensor following development work
reduced the overall system development cycle. 2009 SPIE.
