(1) Material: Metal has good effects for absorbing and loss of electromagnetic energy.
(2) Gaps and holes: The shielding effectiveness of the shielding box not only depends on the material, but also depends on the design of slits and holes of the box.
Detailed design is as follows: 1) To minimize the gaps, shielding box adopts the structure with five surfaces as a whole. 2) Make the side which is perforated and seamed away from the engine compartment. 3) Make the screw holes small to reduce leakage. 4) Cover the wire which connect to the fire protection system host with the shielded line, and use shielding material seal the connector between system and line

X-ray fluorescence is one of the most effective technique for analysing the composition of materials.
Nevertheless the high densities of impurities and defects in the bulk material acting as charge trapping or charge generation centers causes a significant degradation of the signal to noise ratio with respect to what would be theoretically expected.

Introduction Agricultural circular economy is to reduce the usage of non-renewable resources and the emissions of pollutant in production, to restore and ensure the regeneration of the soil, grass, water , forests and propagation resources, to prevent the intrusion of harmful species, to make maximal use of the material and energy in agricultural production, the process of agricultural products and product consumption, to improve the quality and efficiency of economic operation, to coordinate the economy development with resources and environmental protection ,turn the economy to a cyclic economy, finally, to achieve environment-friendly development.
Within the industry the materials which interact as food cycle in the form of ecological food chain .every part in the circulation loop are close with each other; the second feature is green production. it controls the usage of amount of the fertilizer and pesticides; the third feature is clean consumption.
The technical content must be increased; the forestry science and technology should be promoted in undergrowth economy.
