Introduction The inorganic phosphor materials developed fast due to their wide applications.
A lot kinds of materials like organic, inorganic, and organic–inorganic composites have been reported to be suitable for electrospun to form uniform fibers.[11–14] The membranes fabricated via electrospinning have uniform diameter, a large specific surface area and a large aspect ratio, which contribute to their wide use.

The Coode Island Review panel approached a local community and environment organization (Hazardous Materials Action Group) to prepare a report on community right-to-know, “Unlocking the Factory Door” [8].
Chemicals and industry sectors are the two key elements identifying the chemicals reported.
In detail, the general calculation methods include: mass balance, engineering calculations, direct measurement (monitoring) and emission factors.
As in the US, facilities can indicate their environmental performance by showing the reduction of hazardous substance, pollutant or contaminant, the decrease of the hazards to the environment and public health, the increase of recycling, energy recovery, or by introducing equipment or technology modifications, product redesign, pollution prevention, housekeeping improvements, training, inventory control or substitution of raw materials [14].

Analytical Solution to Excited Waveform of Bias Control on Electro-Hydraulic Vibration Exciter Yan Ren1, a, Jian Ruan1,b and Jiyan Yi2,c 1 Key Laboratory of E&M (Zhejiang University of technology), Ministry of education & Zhejiang Province, Hangzhou,Zhejiang,310014,China 2Wenzhou Special Equipment Inspection Center,Wenzhou,Zhejiang,325000,China a rentingting211@163.com, b wxmin@mail.hz.zj.cn, c yiyan706@163.com Keywords: 2D valve, Bias control, Excited waveform, Vibration experiment.
The electro-hydraulic exciter is characterized by its large displacement and strong exciter force, so it is widely applied in many main industrial fields such as earthquake environment simulation, large-scale structural dynamic characteristics test, material fatigue examination and device fault diagnosis, etc[2].
Therefore deeply studying on these analytical solutions could provide certain actual engineering significance and theoretical basis for controlling frequency, amplitude and bias position independently and precisely.
