The selected seeds of six maize materials were sterilized with 0.5% solution of sodium hypochlorite for 20 min [34] and washed five times with distilled water.
A two-way analysis of variance was used to determine the main effects of UV-B radiation, maize materials and their interactions on fresh weight, dry weight, net photosynthetic rate and Fv/Fm.
Among the six materials, Nongda108 and Zhengdan958 showed maximum Fv/Fm of 0.716 and 0.722, whereas Yellow c and Chang7-2 showed a minimum Fv/Fm of 0.641 and 0.664, respectively.

Due to their small size and high surface area to volume ratio, nanomaterials have a different UV blocking capacity from bulk materials [15].
Materials had reflection maxima at 77 degrees of glancing angle.
The materials' nanocrystalline structure was suggested by the large reflection peaks.
The materials have a tetragonal crystalline structure with lattice constants of 1.2291 to 8.6147, which is consistent with JCPDS No 65-4028.

Theoretical Analysis In order to have a better guidance on the production and to find out the factors that can possiblely affect the separation, the theoretical analysis of air separation on the material after shelling of Camellia oleifera should be carried out.Air separation is to use of the different of aerodynamic characteristics of materials to separate, extractions in the field of indoor air cleaning as free individuals rather than groups in the form of movement, Therefore, the movement and dynamic of extractions were analyzed,The extractions of the individual was as a point of mass m.
The acting force on the extractions: P=Fk2=F (1) Wherein:p—the acting force on the point of mass m,N F—the area of material was acted by air flow,m2 kρ—flotation coefficient, νρ—suspension velocity,m/s ν—the relative velocity of air to material ,m/s The direction of airflow with the same force P,Fig.1 shows the determination of the relative velocity,V0 shows the velocity of material falling from the hopper, u shows the air velocity, ν shows the relative velocity of air to material and is equal and opposite to w the relative velocity of material to air. θ shows the angle between air velocity and the horizontal, δ shows the angle between V0 and the horizontal, when the material spended a Period of time to move from the initial position,its velocity becames V.
direction θ, the velocity of material falling from the hopper V0 and the direction angle θ [8-9].
Moreover, the running time of material in the air is related to the height of fan from the ground, so the final distance of material movement in the horizontal direction is related to the height of fan.
The materials was feed into electromagnetic vibrating feeder by hand, dosing can be achieved by the feeder.

It requires a long period and a large amount of rocks for the effective displacement to reinforce the dam, but the dangerous case occurs suddenly and frequently, and depletes the human, material and financial resources causing huge economic losses.
Because they have better overall stability, which could form a steeper slope and reduce material consumption; (5) The tetrahedron-like concrete penetrating frame groups have stronger anti-erosion ability and self-protection ability.

Mechanical and Economic Analysis of Asphalt Pavement Structure on Mix Base PENG Hong-wei1,a , OU Bi-Feng2,b 1Hunan Communication Science Research Institute,Changsha,China 2Hunan ChangXiang Expressway,Changsha,China a5404317@qq.com b395924577@qq.com Keywords: Road Engineering; Mix Base; Asphalt Pavement; Mechanical Analysis Abstract: Based on asphalt pavement design theory and criterions in China, five asphalt structures are put out, including three mix base pavement structures, one typical semi-rigid base pavement structure and one typical flexible base pavement structure.
But the material is not same and the price for different material is different, so the cost performance for each structure is different too.

In recent years, carbon nanotube (CNT) has attracted considerable research attention because of its unique electronic, structural, mechanical and electromechanical properties, making it a novel electrode material in electrochemistry for the analysis of various important electroactive substances, such as phenolic compounds [6].
(Sichuan, Chinese Academy of Science). 2.2 Preparation of the modified electrodes The glassy carbon electrode (GCE, 3 mm-diameter) was firstly polished with 0.3 and 0.05 μm alumina slurry on a polishing cloth followed by rinsing thoroughly with double distilled water, successively sonicated in 1:1 nitric acid, ethanol and double distilled water for 3 min after each polishing, respectively, finally activated by scanning at -1.2 to 2.0 V for 5 cycles and dried at room temperature.1.5 g of MWCNTs were dispersed in 6 mol·L-1 HCl.
When MWCNTs was used as an electrode material, the surface area of the electrode was increased.
