The disadvantage is no nutrients; Organic materials include peat, bark, bagasse, groundnut shell, etc[14].
Consequently, it is necessary developing the novel packing materials to improve the performance of bioreactors.
One is from polymer materials(e.g., polyurethane foam[15]), the other is from the mixture of inorganic and organic matter.
There are two ways to adjust the pH, One is insertion of pH-buffering materials, for e.g.
Comparison of organic and inorganic packing materials in the removal of ammonia gas in biofilters[J].

Because it has great potential in photoelectric field, a large number of materials up to now have been investigated on this effect [7-11].
In 1999, Habermeier found LITV effect in colossal magnetoresistance (CMR) materials La1-xCaxMnO3 thin film which grown on vicinal-cut SrTiO3 (100) substrates prepared by pulsed laser depostion (PLD) [12].
It shows that LaNiO3 single layer and LaNiO3/LaAlO3 superlattice films are all metallic materials.

Fig. 5 Torque-strain curve of Fig. 6 Torque-strain curve of bending tension section (H5) circumferential CFRP strip (H5) CFRP Materials Stress Analysis Circumferential CFRP strip of stress and strain: Fig. 6 and Fig. 7 of the CFRP strip strain-time curves were shown.
The data of finite element analysis was showed that the circumferential CFRP materials efficiency were better than longitudinal CFRP materials.

These multi-functional groups make it possible for lignin to be used as materials to synthesize the polymer materials under suitable reacting condition.
In the case of raw materials and catalyst dosage remained constantly and with epoxy value as the reference standard, the effect of temperature on the synthesis of epoxy resin was studied.

Results and discussion Keeping other parameters of the device unchanged, the different materials of the bonding layer are selected and its thickness of the bonding layer is changed from 0.1mm to 0.5mm.
The device is optimized by selecting the appropriate thickness and materials of the bonding layer.
Finite element method is used to calculating with high precision, short development cycle, which having guiding significance for optimizing the design and improving the reliability of the devices The three typical bonding layer materials of conductive adhesive, 63Sn37Pb and Au80Sn20 change the thickness from 0.1mm to 0.5mm, studying the effects of material, thickness of the bonding layer and stress.
