Taste quality of green tea is usually determined by the professional tea tasters according to the sensory evaluation of teas [1].
For each sample, 3g tea was infused with 150mL freshly boiled distilled water for 5min.
Determination of the ratio of polyphenols to amino acids.10mL of the above filtered infusion for each sample was transferred into a one-mark 25mL volumetric flask and was diluted to the mark with distilled water.
Shown in Fig.1, spectra has absorption bands at 5155cm-1 and 6900-7140cm-1, which are related to the first overtone of the O-H stretch of H2O and a combination of stretch and deformation of the O-H group in water[8], respectively.

The industrial solid waste emissions in China is less than 1 billion tons in 2002 ,but after ten years ,it sharply increase to 3.22772 billion tonnes ; the industrial waste water and sulfur dioxide emissions has also always been at a higher level, the sulfur dioxide emissions remain more than 20 million tons every year, leading to the concentration of sulfur dioxide in some big cities higher 2 ~ 5 times than the standards the world health organization set.
EU has a relatively perfect comprehensive measurement, prevention, restrictions and governance service system for water, air, soil, waste, pollutants and noise,and it is worth our country to introduce and learn from.
For example,there are many relevant policies and regulations in water pollution governance in China, but there is no mutual coordination among all regions and departments, partly result to policies can not be effectively implemented; in terms of environmental technology innovation support, there is no specific requirements for fiscal expenditure using in science and technology,and often these grants are stolen ,greatly influenced the passion of enterprises to introduce and create new environmental technology.
In the sales staff management,most enterprises lack professional technic training, leading to sales staff not familiar with products, so the bad performance in promoting.

For example, according to the natural environmental characteristics, small town can be divided into mountain type, plain type, water town type, seaside type, etc.
Based on functional characteristics, the small town can be divided into scenery tour type (landscape type, rural type, historical culture type), industrial type(resources development type, the traditional technology development type, high-tech products diffusion type), trade type (craft type, professional market-oriented type), etc.
