Water-soluble plastic packaging materials.
PVA has good film-forming property, degradability and water-solubility.
Water-soluble plastics has good degradability, and its degradation products and pollution-free and water-soluble.
Water-soluble tapes can also be made of PVA, which has good tensile strength and is completely water-soluble.
Its final degradation products are carbon dioxide and water.

Water management based on “regional objective ET” had been a hotspot in water shortage region.
ET as a characteristic index of “Actual water consumption” is a principal form of water export for the system of regional water resource.
Analyzing the basic condition of region water resource and structure of water consumption, the theory of water management based on “regional objective ET” could resolve water contradiction among industry, living and ecology through efficient water resources allocation and application of water saving measures which could significantly increase the efficiency of water consumption.
Field Measure of ET Monitoring Field measure of ET was a method that ET information was observed on certain site of land surface by professional instruments and equipments.
Water balance method.

The standard consistency water requirement, setting time and mechanical strength were tested according to GB/T17669.3-1999 and GB/T 17669.4-1999.

Anudem algorithm and parameter Anudem algorithm Anudem algorithm bases on the thin iterative finite difference interpolation algorithm of Thin Plate Spline, can guarantee the accuracy of water relation.
Moreover the water relation and landform relations that accurate degree it expressed was very high, this in the real-time demonstration of the road design regarding the layout design work, the location design and project alternative had good promoter action.
ANUDEM-A professional DEM interpolation software package[J].

We should also encourage and support the professional technical personnel and front-line operational staff to carry out scientific research and technological innovation.
It is also the primary problem of many food factories before the production is begun, which can provide the basis for power, power, water, steam consumption.
We should try to reduce noise, waste gas, waste water and waste residue produced by the running equipment to harmless levels.

Among them, recycling logistics refers to the unqualified goods return, repair and turnover of the rigid packaging from the need to return to the supplier and the formation of the physical flow of goods; waste logistics is defined that it is a real flow which according to the actual need will lose their use value in economic activity item collection, classification, processing, packaging, handling, storage, then transport them to the processing site professional form". 1.2The status of implementation of reverse logistics At present, the implementation of reverse logistics mainly concentrated in the household appliances, electronic products, medical products and other fields.
In recent years, we can’t ignored the different levels of noise pollution, water pollution, air pollution existed in different regions of the world, which are closely related to human life.
Table 1 .Developed country policies and regulations America Solid waste treatment method law,Transportation of dangerous substances law,Resource conservation and Recovery Act Law Japan On the restriction of the factory waste water law,Japanese pollution countermeasures law,Environment white paper law Western Europe Occupation safety and health law,Disposal of toxic waste law, Pollution control method law in 1974 In China, in recent years, put forward the construction of ecological civilization, the construction happy homeland, which are incorporated into China's "eleven five", "Twelfth Five-Year Plan".

The use of mesoporous silica such as SBA-15 (8 g of pluronic 123, 240 ml of HCL, 18.2 ml of TEOS, 60 ml of deionized water) as support for preparing Co-based catalysts has been recently explored [14].
In TPR, each catalyst samples were first purged in a flow of argon at 400 °C for 1 hour, to remove absorbed water, and then cooled to 40 °C.

After they were introduced, it showed the effects on the local soil and water environment in many areas .Moreover, further study also found that it could make the local water quality deteriorating [3], biodiversity decreasing [4], and even present the alien species invasion [5] and other risks.
We can also establish the early warning index, combined with the professional supervision team construction about plant introduction, striving to reduce the blindness of introduction and the risks of the introduction in the greatest degree.

There are 10 faculties and 3 institutes which develop various academic and professional programs.
Along the campus historical vein, it is dotted with decorations, such as the scenery stones and walls and the epigraphy, written with school historical and cultural development; the central axis is decorated with greening, pavement and dry creek in the shape of water waves, implying the winding development of the college.
The greening of main axis of landscape is given priority to low groundcover plants, which build up an artificial micro topography, in cooperation with the pavement and dry creek to reflect the "flowing water".

The Taiyuan City Hall organ office buildings and large public building energy audit main objectives are as follows: Determination of every unit building energy system, and the total energy consumption is assigned to each sub system, including lighting, indoor equipment, HVAC system(including air conditioning and ventilation system, heating system), comprehensive service system(include elevator system, water supply and drainage system, hot water heating system and so on).
On the lamps for energy saving should be the first choice of energy-efficient products, at the same time the lamps line control switch for professional design, So that it can achieve the effect of intelligent control.
