The industrial system should learn from the natural ecosystem. The resource utilization efficiency should be increased and the environmental load should be decreased, depending on the materials recycled in the system. The classification of industrial materials from the viewpoint of large-scale recycling was stated. Recycling of materials, on three different levels, was introduced in the industrial system. The metal flow diagram in the life cycle of products, in the case of no materials recycled, materials partially recycled, and materials completely recycled, was given. The natural resource conservation and the waste emission reduction were analyzed under the condition of materials completely recycled. The expressions for the relation between resource efficiency and material recycling rate, and the relation between eco-efficiency and material recycling rate were derived, and the curves describing the relationship between them were protracted. The diagram of iron flow in the life cycle of iron and steel products in China, in 2001, was given, and the iron resource efficiency, material recycling rate, and iron eco-efficiency were analyzed. The variation of iron resource efficiency with the material recycling rate was analyzed for two different production ratios.

While some pseudogenes have been reported to play important roles in gene regulation, little is known about the possible relationship between pseudogene functions and evolutionary process of pseudogenes, or about the forces responsible for the pseudogene evolution. In this study, we characterized human processed pseudogenes in terms of evolutionary dynamics. Our results show that pseudogenes tend to evolve toward: lower GC content, strong dinucleotide bias, reduced abundance of transcription factor binding motifs and short palindromes, and decreased ability to form nucleosomes. We explored possible evolutionary forces that shaped the evolution pattern of pseudogenes, and concluded that mutations in pseudogenes are likely determined, at least partially, by neighbor-dependent mutational bias and recombination-associated selection.

An air waveguide of left-handed photonic crystal （PhC） formed by holographic lithography is proposed. The symmetry mismatch between the incident wave and the Bloch modes of the holographic PhC is used to guide light efficiently. By properly designing the waveguide, backscattering loss can be significantly reduced. Due to the unique advantages of holographic photonie crystals, the serious problems of material loss and fabrication difficulty in left-handed material waveguides are also avoided. Furthermore it is shown that high transmission efficiency is easily achieved in the frequencv region with effective refraction index near zero. These features may extend the possible guiding ability of holographic photonic crystal waveguide and its promising potential in the application of photonic integrated circuits.

目的评价我国健康教育机构服务效果，找出存在的问题，并给出切实可行的解决方案。方法采用熵权优劣解距离法（technique for order preference by similarity to an ideal solution, TOPSIS）与秩和比法（rank-sum ratio, RSR）模糊联合的方法对我国31个省（自治区、直辖市）的健康教育机构服务效果进行综合评价。结果研究选取14项健康教育机构服务效果评价指标。其中指标权重排名前两位为手机短信覆盖人次数、音像制品数量，后两名为主办网站数、与电视台合办栏目数。经过熵权TOPSIS法评价显示，各地区Ci值在0.022～0.665之间；RSR法评价结果显示，健康教育机构服务效果处在较差、一般、良好、优秀的地区数分别为2、13、13和3个。两者结果与模糊联合模型结果总体趋势基本一致。结论熵权TOPSIS法和RSR法模糊联合可以较好的评价我国健康教育机构服务效果。我国健康教育机构服务存在内容和地区不平衡的现象，应增大健康教育宣传和人力资源的总投入，针对各地区的差异提出因地制宜的措施，以提升健康教育机构服务效果，增强居民幸福感和满足感。

为了研究玻璃纤维混凝土梁的抗爆性能,对1根未掺纤维的普通钢筋混凝土(RC)梁和4根玻璃纤维体积掺量分别为0.05%、0.10%、0.15%、0.20%的玻璃纤维钢筋混凝土(GFRC)梁进行爆炸试验,综合分析玻璃纤维体积掺量对钢筋混凝土梁结构在爆炸荷载作用下动态响应的影响。结果表明:4根GFRC梁在爆炸荷载作用下的加速度、应变、损伤指数值、裂缝数量和宽度均小于RC梁,且玻璃纤维体积掺量为0.15%的混凝土梁各项指标相对最小,表明掺入一定量的玻璃纤维能有效抑制混凝土中裂纹的萌生和扩展,可以提高混凝土梁的抗爆性能,且玻璃纤维体积掺量为0.15%的玻璃纤维钢筋混凝土梁抗爆性能较优。

Two-dimensional granular flow in a channel with small exit is studied by molecular dyhamics simulations. We firstly define a key area near the exit, which is considered to be the choke area of the system. Then we observe the time variation of the local packing fraction and flow rate in this area for several fixed inflow rate, and find that these quantities change abruptly when the transition from dilute flow state to dense flow state happens. A relationship between the local flow rate and the local packing fraction in the key area is also given. The relationship is a continuous function under the fixed particle number condition, and has the characteristic that the flow rate has a maximum at a moderate packing fraction and the packing fraction is terminated at a high value with negative slope. By use of the relationship, the properties of the flow states under the fixed inflow rate condition are discussed in detail, and the discontinuities and the complex time variation behavior observed＇in the preexisting works are naturally explained by a stochastic process.
