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.

But because the magnetic field strength generated by eddy current is very weak, and the electromagnetic wave in sea water is easy to be absorbed by seawater, the detection range is smaller.
We first imaged the lakebed in the water areas without steel tube to test the penetration depth of SAS.
Because the sound wave has penetrability and the sediment exist apertures, after the sound waves go through the water and hit the seafloor, a part of sound waves will continue to spread the depths of the sediments [5], and will be reflected back one after another, different echo will be reflected back when the sound wave hit the armoring layer of SOFC.
FIG.3 3-dimensional imaging of certain bridge pier Problems and solutions of InSAS detection The application of InSAS in the detection of SOFC is different from the general study of InSAS, it has more professional and targeted, some improvement and optimization for SOFC detection need to be done.

Taian is also the middle place of the travelling hot route of “one mountain, one water and one sage” in Shandong Province.
One water refers to Jinan City, which has many springs.
Dongping should highlight the Shuihu Culture, speed up the tourism development of Lake Dongping and build the large tourist holiday resort with hills and waters.
Another very important thing is that tourist practitioners must have a wide range of knowledge and the superb professional skills.

To insure the fully evolution of pearlite and gain different lamellae pearlite prior to LSP, all specimens were vacuum annealed at 1050℃ for 15 min, then put into the salt bath furnace at 600℃, 700℃ for 30 min, respectively, followed by water cooling outside the furnace.
After that, the sample surfaces were polished with SiC paper with different grades of roughness, followed by cleaning in deionized water.
A water layer was used as the transparent confining layer and the professional Al tape with a thickness of 100 μm was used as an absorbing layer to protect the sample surface from thermal effect.

Starch itself is weak and easy to absorb water, so it requires blending with other biodegradable polymers to make the starch toughening and strengthening and meets the requirements of foam preparation.
According to the deliquescence character in the hot water can divide starch into amylose and amylopectin, dehydrate glucose structure of amylose mainly unit to passα-D-(1,4) indican key conjunction, the structure is shown as Fig.1.Straight chain part of amylopectin structure is coupling byα-1,4- indican key, embranchment part is coupling byα-1,6- indican key, such as Fig. 2 showing.
Polyvinyl alcohol, viny alcohol polymer, poval is shortened form PVA, the chemistry structure type is [C2H4O]n.PVA is a kind of water-solubility complex bond, the agglutination mechanism is that impregnate volatilizes while heating.
When standard residual>2, the observation point is excrescent, for these points should combine professional knowledge to deal, the results in this analysis are all in the range of the error margin and satisfied with the requirement.
