Laser polishing technology plays an increasingly important role in the material processing technology.In order to study the influence of scanning interval on the polishing effect of S136D die steel, the single factor experiment method is used in this paper. The continuous fiber laser is used to carry out many laser polishing experiments and the influence of laser scanning interval on the surface morphology of S136D die steel is analyzed.The results show that the surface roughness of polished samples decreases first and then increases with the of scanning interval. When the scanning interval is in the range of 0.03-0.1mm, the surface roughness of samples is relatively flat, and the lowest surface roughness can be reduced to 0.781μm, and the reduction rate of surface roughness can reach 90.2%.

This paper take link mold pellet pelletizer to carry on the pellet fuel manufacture experiment with corn straw stalk. The influence of moisture content, material size and fermentation time impact on broken strength is studied by single factor experiment. Through quadratic regression orthogonal rotating combination experiment, establish mathematics equation of the factors and the straw pellet fuel broken strength and analyze the important degree of each experimental factor impact on the granulation rate. Through the optimized computation, definite optimization parameter of the highest broken strength is that raw material moisture content is 20%, fermentation time is 4h and particle size is 2.5mm. The result of verifying experiment indicat that the optimal parameter combination and the predict data measured were consistent.

This study used Ag-embedded nanoTiO2, xylan and water-soluble Chitosan as antibacterial agents, respectively prepared shutter blades through the treating solution of the different concentration and the different drug loading amount of the poplar veneer. Through a single factor experiment, this paper analyzes that the different antibacterial agent, concentration of antibacterial agent and the drug loading amount have an effect on the antibacterial properties of the shutter blades. The results show that the order of antibacterial performance of the shutter blades impregnated antibacterial agents is the Ag-embedded nanoTiO2, Chitosan, Xylan. Comprehensiv-ely thought the antibacterial properties and economic index, the optimal concentration of the Ag-embedded nanoTiO2 impregnation solution is 1%.

Photocatalyst of Fe-Sm-Yb modified TiO2 loaded on clay brick was prepared for degradation of NH3-N in coking water. The influence factors of NH3-N degradation rates were discussed by single factor experiment and orthogonal experiment. The optimum process conditions of photocatalytic degradation NH3-N in coking water were confirmed. The results show that NH3-N degradation rates 82.23% were highest in the conditions of pH 6.5, photocatalyst charge of 1.4 g, illumination for 6h, reaction at 55°C, calcination at 500°C.

Single Factor Experiment

Single-factor experiment was applied to get the optimum enzyme treatment condition: water bath in the oscillation trough at the frequency of 80 in 50°C with enzyme usage 35 IU/g for 48h. Transmission electron microscope (TEM), laser granularity distributing machine, Fourier transform infrared spectrometer (FTIR) and X-ray diffractor (XRD) were used to analyze the product with enzyme treatment. Observing by TEM, we could see large volume of micro/nanofibrils had gathered together, while fibre was 100-300 nm long and far less than 100nm radial, meeting the requirement of micro/nanofibrils. Being analyzed with laser granularity distributing machine, part of the product had reached the micro/nanolevel. Analyzing by FTIR, we can conclude that after enzyme treatment and ultrasonic dispersion cellulose had no change in functional groups. From the crystallinity atlas, we find the crystallinity of wheat-straw micro/nanofibrils improved from 65.55% to 72.99%, showing that cellulose enzyme destroyed the non-crystallizing field effectively
