Some steel ...Chinese steel industry has made significant progress on reducing fresh water consumption and CO_2/SO_2/COD（ chemical oxygen demand） /dust emissions,and improving comprehensive utilization of solid waste. Some steel companies have become topped worldwide. However,due to the large output quantity of crude steel,the whole steel industry is still a huge source of pollutants. At present,environmental protection standards are encountering challenges of lack of technical support,taxation policy and other issues. Steel industry is currently facing enormous environmental pressure. The development trends of environmental protection technologies were studied by summarizing different development stages. To realize the development targets,the industry needs to carry out its research with independent intellectual property rights,develop comprehensive management systems and establish ecological chain with other industries. This can not only raise the level of environmental protection in a broader range,but also improve the energy efficiency of iron and steel plants and increase added value of waste utilization. Finally,23 environmental protection technologies were proposed and 4 new environmental protection practices were studied.展开更多

The review summarizes the current state of research of two kinds of adhesives, i.e., synthetic adhesives and natural adhesives. Synthetic adhesives, consisting of urea-formaldehyde resins （UF）, phenol-formaldehyde resins （PF）, polyvinyl acetate emulsion （PVAc） and isocyanates, are widely used. For UF, most investigations are concerned with the reduction of free formaldehyde; for PF, most studies focus on finding new chemicals to replace phenol. PVAc has poor properties, but these can be improved by a blending reactions and copolymerization with other chemicals. Isocyanate is an environmentally friendly synthetic adhesive, but also suffers from inadequate properties. Natural adhesives, such as protein/starch, lignin and tannins, have poor bonding effect that limits their level of use, but their main advantages are that they are environmentally friendly and a renewable resource. Studies of modification can improve the bonding performances and gradually cause natural adhesives to become applied in industrial production. Some proposals for future development and the importance of environmentally friendly adhesives are provided, which will be helpful in future theoretical and experimental research.展开更多

The parameters include mean temperature, pH, conductivity, alkalinity, TSS, TDS, DO and BOD which have values of 28.7±0.9 ℃ ; 8.3±0.3; 831±172.5 μS/cm; 165.4±18.3 mg/L; 0.06±0.1 mg/L; 0.4±0.6 mg/L; 7.8±2.4 mg/L and 5.2±1.6mg/L, respectively. Temperature and pH were measured in the field using mercury-in-glass thermometer calibrated in degrees Celsius and pH meter, respectively. TSS and TDS were measured by grayimetric methods, while alkalinity was measured titrimetrically and DO and BOD were measured by Winkler＇s method. For the nutrients, nitrate was measured color±metrically, phosphate by Stannous Chloride method and sulphate by turbidimetric method. Mean concentration of nitrate, phosphate, and sulphate were 15.6±8.6 rag/L; 42.5±19.4 mg/L and 72.3±14.7 mg/L respectively. Nowadays, eutrophication of natural waters is one of the most significant causes of deterioration of water quality, and nitrates and phosphates are probably the key nutrients in controlling the growth of aquatic plants. Though the mean concentration of nitrates and phosphates in the reservoir water were within the acceptable limit, yet their concentrations in some locations of reservoir were high enough to encourage the growth of aquatic macrophytes which would increase productivities. Hence, it is necessary to check their further increase, and periodic monitoring and preventive measures must be adopted to save the reservoir from eutrophication.展开更多

Therefore, government reform, in particular central government reform, provides us another perspective to look at the past 30 years of reform and opening-up. Although China＇s central government has gone through six rounds of reform over the past three decades, goverument reforms still face major challenges. Approached from the relationship between the transformation of the social order and government reform, this paper tries to understand the basic logic behind China＇s government reform. By reviewing the history of institutional reform and analyzing current restrictions that confront China＇s government reform, this paper points out the trends of China＇s government reform. In this paper, the authors try to study the micro and macro motivations of China＇s governmental reform by using public choice theory, and briefly comment on the ＂super ministry system.＂ .展开更多

However,the IPTV service model has not been perfected yet after long-time trial made in a couple of Chinese cities. Selecting optimum technologies for IPTV is difficult to solve in the short term. So far most trial IPTV services in China are designed to provide a small number of local viewers with television and recorded programs. Accordingly,the technology used for the available IPTV services can hardly become a paradigm for future IPTV technology development. Therefore,with the ultimate goal of constructing a countrywide IPTV service network that can meet the requirements of commercial operation,it is necessary to conduct research into the design of countrywide IPTV network architecture,improvement of the bearer network,selection of video encoding technology,terminal structure,building of the Content Distribution Network (CDN),establishment of the open Digital Rights Management (DRM) platform,and construction of Media Asset Management (MAM) system.展开更多

文摘Fast growing IPTV services have become a major concern in China’s information industry. However,the IPTV service model has not been perfected yet after long-time trial made in a couple of Chinese cities. Selecting optimum technologies for IPTV is difficult to solve in the short term. So far most trial IPTV services in China are designed to provide a small number of local viewers with television and recorded programs. Accordingly,the technology used for the available IPTV services can hardly become a paradigm for future IPTV technology development. Therefore,with the ultimate goal of constructing a countrywide IPTV service network that can meet the requirements of commercial operation,it is necessary to conduct research into the design of countrywide IPTV network architecture,improvement of the bearer network,selection of video encoding technology,terminal structure,building of the Content Distribution Network (CDN),establishment of the open Digital Rights Management (DRM) platform,and construction of Media Asset Management (MAM) system.

We provide the novel perspective on the corresponding issues that will be meaningful and important.
