Colour Hologram Making with Diffraction Colour Separation Method

Colour hologram making is an important part of research hologram display technology. Nowadays it has great influece upon improving the hologram display. Although different ways of producing colour hologram exist ,to get the better quality of colour hologram,a new way is found to produce it by diffraction colour separation method. The red,green and blue information code of a colour transparent film can be recorded on a black-and-white film with a three-colour grating. Monochromatic laser is used to reproduce at the same time the distributions of the recorded three-color colour information, and to record them on a holographic film to make a colour holographic image. The remarkable advantage is that there is no need to make three holographic images with information covered with colour selection, that the diffraction efficiency is high,and that the reproduced image is of clear and bright colour.     

Dark Interfere Fringes on Copying Hologram with White Light

The dark interfere fringes appearing on a copying hologram with white light are discussed. Which are caused by the minute distance between the original hologram and the coping holographic plate during the coping process. Two wave fronts of the virtue image and the real image are reconstructed from the original hologram and recorded on the coping holographic plate during the coping process. If the two holographic plates have a minute distance, there are two virtue images wave fronts are reconstructed from the coping hologram. These two virtual images wave front are the same but have a little spatial shift. The two shifted wave front will interfere and produce dark fringes on the hologram even with white light to illuminate the hologram. The methods to eliminate the dark interfere fringes also discussed.

对随机采取的40头(份)市售鲜猪肉进行了9项指标的检测。检测结果显示,pH值、氨值、球蛋白与H2S等4项指标的测定结果与国家标准方法测定TVB-N的结果存在较大的差异,而TVB-N与感观指标、过氧化物酶、菌落总数和大肠菌群检测结果显示出很高的相关性。试验证明,在猪肉新鲜度检测中,建议以TVB-N、微生物指标和感官检查为主要依据,结合其他指标的检测结果,作为综合评定猪肉新鲜度的参考依据。     

Synthetic incentive mechanism

Economic incentives are divided into three forms of incentive means, such as fixed wage, piece rates wage and promotion prize. Relationship between the three means is analyzed, and the notion of synthetic incentive is put forward. An enterprise should apply the three paying means synthetically to stimulate its workers to work hard. How the factors such as the level of ability, risk aversion, product error and difference of prize influence the optimum piece rates, and how these factors and the market price influencing the activities of the workers are studied. The incentive effect of pyramid-stylized wage structure and the internal mechanism that workers are divided into different kinds according to their ability level are analyzed.

Preparation of Porous Hardened Cement Paste Synthetic Filter Material and Phosphorus Removal from Wastewater by Adsorption

Taking cement as primary raw material, a porous hardened cement paste synthetic filter material was prepared by steam curing in a reaction kettle. The optimum process combination condition of the filter material was determined. By orthogonal experiment, the optimal combinations of technical conditions were determined: water-solid ratio is 0.25, and pore-forming agent/cement equals to 0.3 with steaming temperature at 180°C in the reaction kettle for 4 h. Effects of pH value, dosing quantity and the initial concentration of phosphorus on phosphorus removal by using the filter materials which prepared under the optimal conditions were tested. The results show that the phosphorus removal rate reaches all above 95.3% and the highest one is 99.8% when the initial concentration of phosphorus is 5~10 mg·L -1. When the amount of filter material is added 2.5 g/100 mL, under the experimental condition of pH neutral, the top phosphorus removal rate reaches 89.6% when the concentration is 50 mg·L -1. The analysis of adsorption kinetic process shows that the pseudo-second-order kinetic is fitted to the adsorption characteristics of filter material and the adsorption rate is controlled by the intra-particle diffusion.
