In order to improve the quality of personnel engaged in tourism industry, travel agency is necessary to take corresponding measures: First of all, travel agency should develop ecological tourism professional leader.
So it is very necessary to train a number of tourism managers who have the professional knowledge, have sense of responsibility of the ecological.
The tourism destinations in the green marketing should contain many departments to work hard together, however the tourism destinations in the marketing of LPS should create green in traveling hotel, the hotel will take place as a high cost , it consumed a lot of natural resources, emission a lot of waste, lead to the survival of humans worsening ecological environment, and some have even built tourist hotel restaurant in the wild, a lot of hotel even to kill wild animals and precious animal, causing some treasure product starts to decline and extinction, hotel any emissions living garbage, can make in areas around the water, soil, air and by different people health damage, etc.

Investigation on Synthesis Conditions of Silicon- doping Hydrotalcite-like Compounds WANG Lei1, a, XIAO Peng1, b 1 Jilin College of Professional Industry and Technology, China, jilin a wanglei03@163.com,b xp0614@163.com Keywords: Silicon-Doped–HTLc;co-precipitation;synthesis conditions Abstract.
Making up a prescription referenced to the formula of Mg6(Al2-xSix)(OH)16CO3·4H2O, MgNO3 , NaAlO2, NaOH, Na2SiO3, and Na2NO3 solutions were mixed by an experimental ratio, and the mixture was dripped into a flask containing distilled water slowly, Stirred constantly in a pH environment of 8~9.
Finishing dripping, the flask was setted into a thermostatic water-bath for 4 hours.

However, these tests, if carried out on site by site workers, may give inadequate results due to lack of professional knowledge and proper training [2].
The artificial neural networks (ANNs) are a recently popular nonparametric approach to estimate the water quality parameters.
Water-to-cement ratio: W/C = (W+SP) / (C) Water-to-binder ratio: W/B = (W+SP)/ (C+FL+SL) Water-to-solid ratio: W/S = (W+SP)/(C+FL+SL+CA+FA) Total aggregate-to-binder ratio: TA/B = (CA+FA) / (C+FL+SL) Therefore, in this approach, slump of concrete is a nonlinear function of these eleven input variables described above.
Statistical properties of components Components Minimum Maximum Cement (kg/m3) 137.0 374.0 Fly ash (kg/m3) 0.0 193.0 Blast furnace slag (kg/m3) 0.0 260.0 Water (kg/m3) 160.0 240.0 Superplasticizer (kg/m3) 4.4 19.0 Coarse aggregate (kg/m3) 708.0 1049.9 Fine aggregate (kg/m3) 640.6 902.0 Water-to-cement ratio (W/C) 0.5 1.736 Water-to-binder ratio (W/B) 0.3 0.678 Water-to-solid ratio (W/S) 0.075 0.125 Total aggregate-to-binder ratio (TA/B) 2.363 5.562 Slump (cm) 0.0 29.0 Data set.
The highly nonlinear equation obtained using BPN helps us realize the mixture mechanisms in a transparent way, containing only three significant input variables including fly ash (FL), water (W), and water-to-binder ratio (W/B).

Of course, some records in advance are always ready to work processes, inquiry information, blank forms, so that the investigation would certainly be more orderly and professional qualities.
(5) Storage and transport of evidences: Computer evidence should be stored at normal room temperature of the environment, to avoid being moisture, magnetic, dust, smoke, water and oil of.
Hard physical recovery needs professional repair hardware required to open the hard work, you must clean the work indoors.
Finally Investigators can use professional forensic software to analyze user internet history, E-mail records, chat and other communications data.

., Ltd. in 2007 production, the same year on December 20 and put into operation Figure 1 A phase-to-ground lightning flashover discharge Accident Analysis (1) Visual inspection To identify the cause of the accident, the first visual inspection of the arrester found flange three-phase arrester porcelain were filled with water, brown water rendering judgment contains a lot of rust; within the faulted phase arrester fixed rim flange and bolt severe corrosion, explosion-proof membrane damage.
Figure 2 Arrester flange are filled with water Figure 3 Valves scattered cases Internal inspection To further identify the cause of the accident, for the replacement of the three-phase arrester disintegration checks.
Both ends of the cover made ​​of cast iron, cast iron casting themselves poor quality, trachoma and more, there is a gap in the seal groove during processing, so that the sealing gasket installed does not work, moisture and water intrusion from the gap
(3) Infrared Temperature Infrared temperature measurement is carried out in precise arrester charged state temperature, through horizontal and vertical comparison, can be found at a certain degree of deterioration from moisture and lightning running varistor, but needs strong professional testers

The phenomena often appears that sea surface is above land, island is under sea surface and distortion of building inter-island in conflux area of water and land when creating three-dimensional image using fusing DEM and image.
Outlining the main features of the softwear PCI PCI Geomatica is developed by PCI company of Cadana, which has the functions of processing RS image, photogrammetry, GIS spatial analysis, professional graphics, powerful file management features, secondary visual development environment.
Generally speaking, there isn’t this step which modifies DEM in 3D RS image production process, but the study area land and water are much of the possession, if we did not modify the DEM to obtain the 3D images, then the elevation displayed by DEM at the junction and the contents displayed in image do not match, some land sunkenes below the water, some water raises above the adjacent land, and the bottom elevation of all water bodies in accordance with its ups and downs do not match with the actual water height.
Issuesing and Analysising to general practice of 3D Rs image Zhoushan area accounted for a large part of the water body, the DEM in water body is the elevation values of the bottom, while the DEM value displayed in the image is the one of the surface water ,there will be 3 problems if we directly interge the original DEM and RS image to produce 3D RS images .
Modify the principle of modification is that the elevation of the seawater is to make consistent, depression of the land rose up and raised the water falling down, the Inter-island structures returne to normal form.
