Besides other relevant factors, there will be taken into account the location of emission sources, the nature of professional activity, the direction and size of air currents, the presence of other particles that might influence the measurement results.
In fact, it is virtually impossible to follow the progress of nanoparticles in the environment and there is no way to remove them from air, water, soil, which could possibly bio-accumulate in the food chain.

Ozone concentration were continuously monitored by O3 analyzers (S-900 Aeroqual, New Zealand), and were controlled by computers, using a professional program for O3 dispensing and monitoring.
Keep the experiment at uniform water and fertilizer, no other constraints such as pests and weeds.

Agricultural bank support as the backbone of the development of county economy and the pillar, make full use of in the capital, the county network and professional advantages, and constantly stability and development in the county and rural areas of the network and service; Rural credit cooperatives, through the constantly promote and perfect the corporate governance structure, actively and carry out its reform policy support and financial strength, innovation service support products, to adapt the strategic adjustment of agricultural structure; The state-owned commercial Banks and the joint-stock Banks actively expand the county economy of the credit business; Each city commercial bank through the enhanced support the development of county economy, promote the strength of the product innovation, make more money for the county economy; Agricultural development bank earnestly perform their functions in policy at the same time, increase support for county economic development, risk control
At present the whole province rural form scale, development of relative molding innovative financial products including: innovation pawn, credit enhancement, credit evaluation, credit and other financial services to combine together, simplified loan procedures, there are five kinds of nine varieties financial innovation, the farmers and small and medium-sized enterprises have the forest of agriculture, water use, machinery, warehouse receipt, the contracted management of land can't be as a pledge assets and right, can be used for mortgage guarantee resources can be converted into the financial support.

The temperature increases slowly in the crucible, and reaches the maximum in the middle of the crucible, and then decrease slowly; in the region of 150 mm to 300 mm in z direction, the temperature of metal vapor decreases rapidly, to 164.9℃, 169.2℃, 177.5℃, 186.4℃ and 195.3℃ respectively with various heating body temperature, and then decreases slowly to the temperature of water cooling trap, that is 50℃.

Before using the alumina tube, it was fully cleaned by HCl / HNO3 and then distilled water to remove the contaminants from the tube.

Catalyzed by catalyst（such as copper oxide）, hydrocarbon is decomposed into CO2 and water, and the alkaline substances and desiccant are used to purify oxygen.
As an analyst, we should master the professional skills and operate rigorously so as to obtain correct analysis results.

They cause high environmental risks that are manifested in their impacts on land, subsoil, and soil resources, as well as air, underground and surface waters, vegetation, and animals.
The analysis of professional diseases receives minimum attention, and many employees expose themselves to risks because they do not know about the consequences of inhaling stone dust during their work.

Design, Construction and Instrumentation of the PCCV Model The PCCV model is a uniform, 1:4-scale model of the containment structure of Unit 3 of the Ohi pressurized-water reactor Nuclear Power Station in Japan.

Some designers are not familiar with the design codes of steel construction, and lack of professional training of steel structure; some products are designed by manufacturers and design institute signatures.
Otherwise, because of long-term exposure to outdoor for steel sheet material and other components, the atmospheric and water stability is poor, premature corrosion and lower strength may occur, and the maintenance period will be shorten, leaking phenomenon will also occur. Ⅵ Conclusion (1) On the basis of the characteristics of granary railway canopy, although there is no design codes for arched roof structure, combined with the more complex factors, the design has regulations to follow in accordance with the relevant codes.
