Fig. 2 The diagram of the three-phase anaerobic Fig.3 The structure diagram of the modified digestion process UASB reactor Compared with the traditional UASB reactor, the reactor used in this test has been added the anaerobic contact oxidation fill area on traditional UASB reactor,the filler material was 2 x 3 cm cylindrical PVC materials, this method not only increases the attached area of anaerobic microorganisms, but also increases the contact between the anaerobic microorganisms and organic matter.

Introduction Survey, design, construction, use, material aging, natural disasters and other various reasons influenced the RC buildings that have been built, and there is serious security problems which will pose a great threat to the safety and property of people's life.
(4)The material of reinforced concrete, the interface between polymer mortar and concrete , the interface between high strength wire and polymer mortar are sticked better. the strain among them are coordinate, no slide and not speel off
The Material constants are different, the Poisson's ratio of concrete is 0.2; fixture and strand apply LINK8 unit and BISO constitutive model, that is, Bilinear constitutive model.SOLID65 unit and LINK8 unit share node, that is, the Poisson's ratio of fixture is 0.3 when the Bonded slip can be ignored.

For optimization, the bridge is constructed as a hybrid system, with different materials used for main and side spans to balance the forces induced on both sides.
Namely, the side span of the bridge was built using heavier, concrete-based materials, and the main span using lighter, steel-based materials.

Axial compression, the initial testing machine is the work done by the energy dissipation of the rock material.
From this may know, is in peak strength of rock after absorbing energy is mainly used to internal material plastic sliding between doing work.
Summary The destruction of the rock material and energy is closely related to the changes, especially in the high ground stress conditions.
