Integrated standardization is one of the fundamenta l forms of modern standardization. It is the combination of system science and the content of standardization. The development of system science has provided theo retic foundation and precondition for integrated standardization. The relevant r esearch on integrated standardization and system engineering illustrate that int egrated standardization is a advanced method which presented with the developmen t of modern science and technology . Integrated standardization treat the re levant factors of standardization as a system, and wholly standarlize the factor s in order to reach the best level of technology and quality. Integrated standardization is a large system engineering. In modern industr y the contact among different departments is being constantly enlarged and t he complexity of product is being constantly increased. This situation demands s trict correspond and united request in all the following aspects: raw mate rial, organs, fittings, technical measures of production, preparation for produc tion, ways of organizing the production. The traditional measure which establish the respective standard separately must be replaced by multi-spetialty standa rdization in large spectrum. The current situation and the development of syste m science has provided theoretic foundation and precondition for this kind of st andardization. Product or project can be managed with system engineering of proj ect, while the correspond standardization can be managed with system engineering of standardization. Integrated standardization virtually is system engineering of standardization, w hich use the theory to deal with the problem about standardization . This thesis included 3 chapters: 1. the brief summary of integrated standardization and sys tem engineering management in the development of type in foreign countries; 2. t he current situation and existing problems in the development of products; 3. ho w to organize and actualiz

Bordering eastern Mongolia,Zabaikal and far east of Russia (Fig.1),the region of interest lies in the northeastern part of china,which is the largest alluvial gold concentration district in *** a great deal of exploration work has been carried out in the region for more than 40 years,only several lode gold deposits with varied sizes have been discovered and mined in eastern and northern parts of the *** is that most known lode gold deposits in the region are among small and medium sizes? Is there any potential of finding new lode gold deposits? This paper attempts to give some new ideas on the genesis and evolution of lode gold deposits in the region and proposes some new prospecting targets.

This paper discussed the spatial distribution of soil erosion in china at the end of the 2.th century based on the second national soil erosion survey. The result indicated soil erosion is still the prime environmental problem in china. Soil erosion mainly occurs in the western regions of china, and the slight erosion type, ion the whole, exerts the greatest impact on soil erosion pattern. The distribution of water erosion shows the impact of landforms: slight water erosion mainly in mountainous and hilly areas, and half of violent water erosion on the loess landforms. Farmland, forestland and grassland are the major land use types of slight hydraulic erosion distribution, while the serious hydraulic erosion and slight wind erosion mainly occur on grassland. Thus, the conservation of the grassland is the key to either hydraulic and wind erosion control. The huangmian soil (a major type of cultivated soil developed from loess mother material) is the one facing the most serious threat from soil erosion in chinas soil resources. Further discussion on the soil erosion distribution still needs more research on the method and relevant data analysis.

Mammalian mitochondrial D-loop L-strand RNA (DL-RNA) is thought functionally not important because no obvious function has been found so far. In this study, we detected a novel D-loop L-strand RNA (DL-RNA) in mouse mitochondrion by RT-PCR. The L-strand RNA spans the whole D-loop region of mouse mtDNA, and is resistant to RNase A and RNase T1 but not RNase H digestion. After binding of the L-strand RNA to D-loop, the DL-RNA complex can protect the D-loop from digestion by restriction endonucle-ase Hae Ⅲ. These results indicate that a novel RNA-DNA triplex hybrid (R-loop) can be formed in mouse mtDNA D-loop region, and that the DL-RNA structure is capable of protecting the D-loop from certain microbial restriction enzyme digestion. And the similar R-loop structure can not be found in Cyt. b gene in control experiment which confirmed this R-loop is not the fleeting structure in RNA transcription. Considering the D-loop represents the control region of mtDNA, the novel triplex DNA-RNA complex may play an i

Guanling biota has been found at the bottom of Wayao Formation of UpperTriassic (Carn-ic stage) near Xinpu town, Guanling County, Guizhou Province, china. There are a lotof crinoids and marine reptiles, which is a characteristic of Guanling biota, including ammonites,bivalve, brachiopod, fish, conodont and plant. These fossils are featured not only with the largequantity, but also with their extraordinary perfect forms. This paper explores the meaning,geological background, present situation of study and scientific significance of Guanling biota.
