The hydraulic retention time (HRT)[2]and sludge retention time (SRT)[3]achieves separation .The trapped biodegradable macromolecular organic matter reacts and degradates continuously in the reaction tank.BMBR has high efficiency and good water quality, meanwhile ,its area is small, the operation and management is simple[4].However, serious membrane fouling[5-7] as well as a large number of surplus sludge affect its application.
The most important properties of the carrier: (1)Excellent physical properties; (2) Adequate mechanical strength and stability; (3)Good surface charged properties; (4)No toxic or inhibitory; (5)Cheap. 1.3 Test operation Sewage passes through gas-water mixer into the treatment equipment, the gas - water mixer passes through micro-fixed bed from below .Then water flows porous micro-membrane under the action of hydraulic pressure.
Considering water quality standards [10]and economic factors ,HRT 3h ~ 4h is the most suitable . 2.3 SEM （Scanning Electron Microscopy ） Analysis Under the stable operation conditions , a small piece of carriers seperately is taken out at 0m(bottom),0.5m,0.8m and top , Carriers color is yellow at the top of fixed bed and the lower part is black.

Small Punch (SP) testing is an innovative test method utilised to assess the mechanical properties of small volumes of material.
As such, the SP technique would offer an ideal approach for characterising the mechanical properties of PB-DLD material.
The effects of build orientation on PB-DLD C263 microstructure and resultant mechanical properties through SPT testing are also evaluated.

The current methods are mainly qualitative methods, which could not point out the factors that affect the system safety and its extent.
It is necessary to consider various factors for complex system such as cranes.
The factors are taken down layers compared with each other basing on the factors up layers, and then comparison matrix is structured.
With consistency test, the weight values for each factors are calculated[2].
With the experts evaluate on various factors of each layers, evaluate importance of evaluation factors on all layers by fuzzy value of the Table 1, then calculate the weight values of each safety factors by Equ.2, form the Table 2 ~ 6 as follows.

However, in practice, nitrogen hardly affects the Hall-Petch coefficient as mentioned above.
Besides, the equation (2) contains an uncertain factor r.
On the discussion in tensile strength, Taylor factor has to be considered.
Taylor factor is 2 for bcc Fe.

Preparation of a Superhydrophobic Carbon Film by a Novel Vapor Phase Transport Process Gang Li Laboratory of Ministry of Education for Conveyance and Equipment, School of Mechanical and Electrical Engineering, East China Jiaotong University, Nanchang 330013, P.R.
The surface of morphologies of the pure nickel surface was characterized using a non-contact mode of atomic force microscope (AFM) and the structural properties of as-grown carbon film was characterized using scanning electron micrograph (SEM).
Since the surface energy is an intrinsic property of materials, wettability is usually enhanced by the increase of surface roughness, especially by fractal structures [3].
The results showed that such a lotus-like structure with micro and nano-papillae in the film, which was strongly affected the contact angle and the rolling angle.
