Adipic acid (ADA) is known as hexane dicarboxylic acid, which is white monoclinic crystal at room temperature, it is an important chemical raw materials and synthetic intermediates, widely used in the production of nylon 66, plasticizer, lubricant, polyurethane foam medicine, spices, in addition to adipic acid is also used as a food acidulant, an unsaturated polyester, etc.
Adipic acid is used as an important chemical raw materials, and its industrial production methods are still used mainly nitric acid oxidation method.
With strong worldwide demand for synthetic fibers, plastics, polyurethane material, adipic acid production grow by average annual of 2 % [5].

Introduction From several years nanocomposite materials are a very important topic in material science [1].
In these materials, this behavior is due to the presence of structural relaxation processes.

Materials and methods Experimental Field Condition The research site was located in Shiping forest farm, Fengdu County, Chongqing Province, China.
Materials and Methods Collecting 2000 ripe and plump Castanopsis fargesii and Castanopsis carlesii seeds respectively when the seeds fell off naturally, and setting forest gaps (oval, about 57 m2) manually, then we carried out Castanopsis fargesii and Castanopsis carlesii seeds burying experiment respectively under two forest conditions(gaps and under-canopy), and burial depth in the soil was 0.5cm.

In fact, the void is inevitable with the current state of materials and construction method.
Classification of the Void The void of Concrete Filled Steel Tube is generally divided into two categories, the first category is called void caused by the non-compacting, and defined as the void caused by the holes due to the defects of quality, materials, constructions and technology between the core concrete and steel pipe.
Its fundamental principle is to make the defects such as micro-cracks and pores of the concrete least through reducing the particle size of raw materials, using reasonable gradation to increase the packing density of the material, then to obtain the largest carrying capacity and excellent durability determined by the material.
The raw materials include sands, high efficiency water reducing agent, short-thin steel fiber, etc.
