Decrease the temperature to the indoor’s when it deposits totally, and clean it several times using ethanol absolute and distilled water.
Finally the light red solid powder is obtained after the operations of cleaning several times using ethanol absolute and distilled water and dry under the invariable temperature.

The mixture was then washed with deionized water for several times, until the pH of solution approaching 7.
A pellet of MXene Ti3C2 together with the professional radon monitor model 05-240, thermometer and hygrometer were placed in closed, fabricated container to calculate the radon concentration by time.
Centrifugation was then performed to separate the solids, which were then washed with deionized water.

Other programs are chilled water treatment and upgrading building control system with energy monitoring system features in June 2011.

The samples were first cleaned with trichloroethylene, acetone, and methanol, followed by immersion in buffered oxide etch (BOE) solution for about 1 minute, then rinsed in deionized water.
When a thin translucent layer was deposited, which usually took about 10-15 minutes, the samples were then rinsed in deionized water and blow dried.

POI is widely used in professional map production vehicle navigation, communication and express, etc.
The modes of transportation of the modern logistics: highway transportation, Railway transportation, Water transportation, air transportation and pipeline transportation.
Highway transportation is a mode of transportation that transport passengers and cargo by using vehicles on the road, it is mainly responsible for the transport of short distance or small amount of cargo, and be responsible for the transport of some long distance or big amount of cargo for the areas that other modes of transportation are hard to reach, highway transportation can also transport for short distance that railway and water transportation cannot reflect their advantages.

In China, there are two professional journals publishing papers on wetlands, Wetland Science and Wetland Science & Management.
Tab.2 Major English journals publishing wetland science papers written by Chinese researchers (1957–2009) Order Journal Number of publications Percentage (%) Impact factor(2008) 1 Wetlands 248 7.74% 1.117 2 Ecological Engineering 81 2.53% 1.836 3 Journal of Environmental Quality 60 1.87% 2.145 4 Hydrobiologia 50 1.56% 1.449 5 Water Research 41 1.28% 3.587 6 Aquatic Botany 37 1.15% 1.129 The author distribution of the wetlands scientific literature During 7,788 Chinese and English literature published by Chinese researchers, there was totally 6,121 first authors published paper, accounted for 78.6% of the total number of all the literature, this close to Lotka's inverse-square law, author who published one paper account for 60% of total calculated value of all author [8], it indicate that the author distribution of wetland scientific literature normal exist discrete description.

Research on Regional Logistics Spatial Evolution Based on Geographic Simulation System WANG Wei1,a, FENG Xue-jun1,b 1 Water Transportation & Logistics Engineering Institution, Hohai University, Nanjing, China a13813826667@163.com, bfxj@hhu.edu.cn Keywords: Logistics space evolution; Multi-Agent (MA); Cellular Automata (CA); Geographic Information System (GIS); Geographic Information System (GSS) Abstract: To explore development and evolution mechanism of regional logistics system, analyzed complex regional logistics system consists of certain types of entities such as logistics supply sides, logistics demand sides, the government and its professional management departments, it is mainly studied that the physical flow process between logistics supply side logistics demand side and the corresponding size, structure and layout evolution and optimization process between and within the regional logistics.
Complex Adaptive System (CAS )-Based Allocation and Management of River Basin Water Resources.

Moreover, to assess the renewable energy technology, Evans [10] proposed a number of indicators, like price of electricity generation, greenhouse gas emissions, availability and technological limitations, efficiency of energy generation, land use, water consumption and social impacts.
This method is often used by academics and professionals to decompose a complex problem into several sub-problems by analyzing the several relevant criteria [13].

At present, only four enterprises with a certain scale mainly engage in research, development, production, sale and technical service of solar product including flat solar integrated heating system, flat plate solar collector, vacuum tube solar water heater, gas boiler enamel interior tank and heating radiator.
At present, the wind industry standard system has matured which include wind basis standard sub-system, wind generation standard sub-system and wind water standard sub-system.
Figure 3 shows the lack of standard is mainly about photovoltaic power plant, solar water heating system, wind turbine.
For example, heat metering of solar water heating system, technical requirement and test method about water tank of domestic solar hot water system, solar air collector technology provision and test method. 3)Wind resources and wind farm monitor standard is still in the drafting stage.
At the same time, we should establish professional technical team and carry out standard system construction. 3) In relevant enterprises, policy advocacy and business training about industry standardization should be strengthen and make them understand product quality problem virtually is every link standardization relating to product.
