The adsorption amount was higher than pure silica material; moreover the composite desiccant can effectively prevent the formation of salt solution for lithium chloride.
The main design idea of composite desiccant was to contain the silica-based materials full immersion in the lithium chloride solution to form intermediates, and then dealt with the intermediates with forced lyolysis in the hot and humid environment, finally formed the new composite desiccant.

In order to know the Micro character quantitatively in this paper the adsorption instrument of analysis and test center in East China University of Science and Technology was used to measure the pore structure of silica gel and composite desiccant.

Dong et al (2003) proposed network model, which thought that supply chain is a logistics
network structure which is linked by the plan, coordination, controlling and processing of raw
materials, even the final products; Chen G.H. et al (2004) thought that the structure of supply chain
could be divided into the chain structure and the network structure.Ma S.H .et al(2005) proposed that
the structure of supply chain could be divided into the chain structure and the network structure; and
they put forward the core business-center structural model.

Experimental Materials.
Ltd., Chloroform purchased from EM Science (NJ).
At this particular concentration, the surface roughness of the material increases extremely leading to the reduction of the interfacial tension between polymer and water and therefore the nanocomposites become more hydrophobic [10].

In our experiments, we found that chlorogenic acid exhibited high content in Flos Lonicerae material and good absorption in evaporative light scattering detector, so it is reasonable to determine the three indicator only with ELSD.
Materials and reagents Seven samples (No.1-No.7) of Flos Lonicerae were gathered from Ziyuan county, Guangxi province, and nine samples (No.8-No.16) from Longhui county, Hunan province.

Keywords: RPC, RPC box pier, Seismic performance, Hysteresis curve, Horizontal load.
Since the properties of RPC bridge piers, such as the stress, deformation, load capacity, and failure mechanism, are different from ordinary concrete (OC) and high performance concrete (HPC) piers, it is necessary to do more seismic performance tests, and build a new and more accurate model for RPC material instead of the restoring force model of OC and HPC.
They designed the RPC piers according to the relative Chinese design code of viaduct, and verified the accuracy of the design of RPC by using finite element analysis to calculate the mechanical properties of RPC piers in normal use limit condition, the stability, ultimate bearing capacity, seismic performance, and then concluded that RPC piers possess better seismic performance using even less materials.
Fig.1 The size and reinforcement of cross-section for the test pier (mm) The compositions of RPC The materials and the ratio of compositions of RPC are showed in following and Table.1, respectively

Termite takes timber and other organic materials as food, and in the long process of evolution, it can achieve co-evolution with various kinds of microorganisms in the living environment by taking advantage of complex organics and degrading complexus.
Material and Method Sample collection and selection of hindgut contents Around about spring and summer in each year, one can make use of pine wooden box as bait and bury it in mountainous or hilly lands of southern Hunan Province for one month.
As for compound like benzpyrole, it was generally regarded as the product of tryptophan metabolized by lignin or termite itself after pyrolysis [5], while, there were also researches hold that they were raw materials needed by fungus to compound various kinds of secondary metabolites containing nitrogen aromatic, and some researches also found that tryptophan and its ramifications in white-rot fungi can stabilize and enhance the activity level of lignin peroxidase and laccase [6].
