Being in gaseous state, 222Rn is easily released into the atmosphere, either directly from the U-238 decay or from underground materials like soil, stones, sands, flow water and etc. [2-4].
The foam material was diluted with water using the ratio of 1:19 (0.2 L Foam material + 3.8 water = 4.0 L foam material solution).
The building material sample, LFC 1 together with the professional radon monitor model number 1027, thermometer and hygrometer were placed inside a closed fabricated perspex box.

This method to guide the word as the core, the more relevant professional analysis team to review systematically the analysis object, this method has the advantages of comprehensive, system, can effectively identify the potential risk of process device, to prevent accidents, especially major workplace accidents have very good effect[1][2].
Workpiece through the transmission line from treated by heat treatment furnace and into the quenching oil pool, oil pool: 2.5×5.4 × 2 m3) quenching, control the oil temperature 60 ˚C (quenching oil pool are circulating cooling water jacket and adjusting temperature).
Artifacts with the oil transmission pipeline out continue to slow, to the workpiece temperature below 30 ˚C, in clear water tank with water after cleaning, artifacts into the tempering furnace, tempering temperature control at 400 ˚C or so, and the mechanical cooling, blasting.

Corrosion occurs due to the presence of carbon dioxide (CO2), hydrogen sulphide (H2S) and free water.
Furthermore, it is also influenced by temperature, amounts of CO2 and H2S, water chemistry, flow velocity, oil or water wetting, and composition and surface condition of the steel [4].

Fig. 3 The surface infrared image taken by the thermal infrared imager carried by the airship Fig. 4 TH9260 thermal infrared imager Indoor work is achieving the operation of geometric correction, color processing and image mosaic to make infrared images meet the research standards by the professional software Image Processor Pro 2, which is taken by the infrared imager.
Point 1 is for water; point 2 for concrete ground; point 3 for white brick ground; point 4 for shale brick ground and point 5 for asphalt road.
Set the sampling interval as 1 min. when measure water surface temperature, put the thermocouple’s test point of the LuChang wind meter in water (about 1cm deep).

The big advantage of PVA for this purpose is the fact that it is water-soluble.
Mix composition was the same for both mixes (450 g of cement, 1350 g of sand, 225 g of water), the only difference was the cement type used.
Water solution of rhodamine B (0.05 g per liter) was prepared, 0.5 ml of the solution was applied to the area of approximately 22 cm2 in the middle of each sample.
Indoor photographic studio equipped with Nikon D300 camera and professional flashing lights was utilized.

Soil heavy metal pollution which brings a threat to agricultural product quality could cause surface water and groundwater contamination, and cause the food chain poisoning[1-2].
Natural Zeolite magnesium oxide and FeSO4 have been chosen as fixative and leaching solvent select demonized water.
After mixing, add water to 60% of field capacity, cultured for two weeks set aside at room temperature.
Before start of the leaching experiment, the weight of soil column was measured, then placed the soil in the plastic trays wetting from the bottom of demonized water and maintained it at the room of temperature 1 week determination of the weight of the soil column after absorbing water.

The professional function is mainly composed with manufacturing, high-tech and tourism industries, partly with the municipal public service centers, cultural sub-center, business associate center, high-tech R & D base.
The landscape features of Jiangnan in Changzhou will be extended, water will been taken as the key link, green as oriented, and the city as the project, water green will be dependency, and good urban ecological environment will be built.
An east-west axis named "Long Yuan green axis" which is 1200 meters length and 150 meters wide will be focus planned in order to link up the river water of Zaojiang River and the green of Dinosaur Park.

In order to exploit resources and develop tourism, the professional of geography firstly defined the types and the concepts of tourism resources.
To see the beautiful scenery of Tianshan Mountain must go to Xinjiang; to experience the passion and vigor Water-sprinkling Festival has to go to Yunnan; to understand the charm of the poem “the West Lake looks like a fair lady at her best, whether she is richly adorned or plainly dressed" must go to Hangzhou; as long as after visiting Lushan Mountain can understand the meaning of poem "I can’t tell the true shape of Lushan because I myself am in the mountain".
Natural tourism resources not only includes landscape scenery of famous mountains and great rivers, water scenery of oceans and lakes, but also includes exotic and rare biological species, even changeable weather and climate phenomenon, such as the solar eclipse, lunar eclipse, etc.
Without the tourism resources, the development of tourism industry would become the water without source, the trees without root.

Introduction Asphalt concrete is the most commonly used material in pavement construction today because of its favorable properties such as elasticity, stability, durability, and water resistance.
Asphalt mixtures are used as surface or base layers in a pavement structure to distribute and transfer stresses caused by loading and to protect the underlying unbound layers from the effects of water.
In order to adequately perform both of these functions over the pavement design service life, the mixture must also withstand the effects of air and water, resist permanent deformation, and resist cracking caused by loading and environment.
