In 2012 and 2013, the situ experimental plots in mulberry under two different kinds of treatment(control fertilization and farmer's conventional fertilization) were conducted, and the runoff water in each plot were collected and tested in a period of two years to investigate the law of runoff, the regular pattern and the influential factors of nitrogen and phosphorus losses, and to study the coefficient of fertilizer losses from mulberry in northern Zhejiang plain. The results showed that the annual rainfall runoff coefficient was about 0.253 in mulberry field in northern Zhejiang plain. In those two years, TN and TP cumulative loss load in the conventional fertilization area reached 36.13 kg·hm-2 and 3.49 kg·hm-2, of which the N, P nutrient losses of fertilizer reached 6.415 kg·hm-2 and 1.090 kg·hm-2, respectively. N, P loss coefficients of fertilizer (the difference of nitrogen or phosphorus loss in the conventional fertilization area and the control area was divided by the total amount of fertilizer application) were 0.744% and 3.047%. Nitrogen loss were mainly in soluble form, in which the NO3-N and NH4-N, accounting for about 38.3% and 14.4% respectively; while the phosphorus loss were in particulate form, accounting for about 68.9%. The larger amount of nitrogen and phosphorus nutrient loss, were within the first year of the fertilization period, and the P loss was more serious than N. Within a period of fertilization, the cumulative loss of nitrogen and phosphorus caused by rainfall and the occurrence times of runoff increased with power function(R2>0.95).

Under the background of third party institution of Chinese testing industry, the promotion factors of development of the third-party institution in China were analyzed. The paper chose SGS which was the largest testing and certification organizations in the world and Huace which was the first successful listing and the largest domestic private testing organization of China as the research objects, by analyzing the development process of these institutions, the different paths to their development were summed up, revelations for China to build national brand was put forward based on above study.

With the approaching of China's entrance to WTO and the development of globalization, the detection institution in the detection market that served as service type appeared the globalized trend, foreign invested detection institution flooded in and the rapid expansion of the size of the private detection institution which made the main structures and requirements of the China detection market being deep transform, and the ways and means in organization and management of the detection institution had a great change. For the sake of the participating the international market, China detection institution should fit in with these changes mentioned above. So in this paper, the adjustment of the strategy of management system and operational mode, and the reform proposals of the strategy of system mechanism, specialized technology and talent supporting were discussed.

The input-output table revealed the relationship between economic and technology of the interdependence and mutual restraint of national economic sectors from the production inputs and outputs point of view, which was the effective tools for macroeconomic analysis and policy simulation. By the Chinese input-output tables in 2007 that included 135 departments, a wealth of macro-economic information was provided, the relationship between economic scale, industrial structure and its present situation were systematically analyzed, and the countermeasures for the further optimization of allocation in order to promote the upgrading of industrial structure were proposed.
