The job site should be installed eyewash and emergency shower spray equipment and ensured continued water supply for 24 hours, so that we can take emergency treatment immediately when the acid splashed into the eyes or skin. ③Storage of sulfuric acid should avoid contacting with other combustible matter and oxides, storage areas should be separated from other houses, and have good ventilation, and block the sun and other heat sources.
Places for mix, irrigation of acid , chemical synthesis processes and places where toxic liquids is easy to leaks, should use corrosion-resistant materials to be the floor, and the floor should be smooth, non-slip, easy to clean and not seep water.
And at the same time, the interior walls of the buildings, columns, roof trusses and roof should take effective anti-corrosion measures . ⑤The floor of the factory should be hardened and the wastewater collection and treatment ditch and pond should also be hardened and anti-corrosion protected, so that to prevent lead, acid waste water get into the ground, polluting the water underground. ⑥In the factory, comprehensive combination of centralized and local ventilation system should be adopt.
Pre-service, during the post and departure occupational health inspection requirements and verification points 3.1 Occupational health inspection requirements Occupational health checks include pre-service, during the post, departure and emergency health checks; enterprise should chose a qualified occupational health professional institution to conduct the undergo health checks at work. 3.1.1 pre-service health check Pre-service health check is to arrange jobs (positions) based on the health status of workers, reduce and eliminate the occupational hazards health damage to sensitive populations, to prevent occupational diseases; avoid recruiting into the plant the person who has suffered from occupational diseases, to maintain companies’ and workers’ the legitimate rights and interests .

Norman, Blackie Academic&Professional, London, 1988, p. 117.

It is a building (APM), the structure, equipment (water WPM, warm HPM, electric EPM, air conditioning CPM), budget estimate (STAT) and construction in one large integrated CAD design system, both between the various modules for data conversion, interface, can be used alone.
The reason is that many architects did not got systematic professional knowledge, although some personnel grasp of the use of structural design software capabilities, but lack of understanding of the concept on the overall structure, or are over-confident on the results of computer analysis of the structural calculation model and the actual building of the great difference, or technical conditions due to a software error caused a clear understanding of the results.

For example: (1) electrical performance and (or) mechanical properties tested in accordance with professional standards; (2) no significant component dark black metal, metal joints without serious corrosion, corrosion of the metal protective layer of 30% of area; (3) paint materials no bubbles, wrinkling, cracking or peeling; (4) no obvious white non-metallic materials, swelling, blistering, cracking and other wrinkles.
It is suitable for the condensation as the main mechanism of moisture or water vapor can accelerate respiration test sample into the test.

The cooperatives in Taiwan Golden Triangle areas established a whole course perception and control system of tomato plantation[5] , which includes five sensing modules, and can collect automatically growth information such as temperature, humidity, conductivity, light intensity, air pressure and wind speed, transmit the information to the host via wireless networks, then with the help of programmable logic controllers(PLC), drive various electrical and mechanical equipment for proper watering, fertilization or shade, and adjust and maintain the growth conditions of tomatoes in their best state to obtain a bumper harvest of high quality tomatoes.
Conclusion Application results show that the apple orchard intelligent monitoring system can monitor apple growing climate and environment in real time and accurately, forecast seasonal pest disease conditions, provide automatically apple planting proposals, address the inconvenience of artificial field sampling and recording data manually, improve the level of apple orchard professional monitoring and management, and provide support for cooperatives to master apple growing conditions, guide orchard operations, analyze historical data to improve varieties and production technology.
