Strategies of Exploitation and Protection 5.1 Increase the Weight of Science and Technology in Exploitation and Protection of Sports Tourism and Leisure Sports Resources We should Increase the weight of science and technology in exploitation and protection of tourism and leisure sports resources, in which science and technology methods are adopted and blind and invasive extensive exploitation is turned into intensive exploitation, to the greatest extent, and reduce the destruction caused to resources during the process of exploitation.
Therefore, exploitation and protection of tourism and leisure sports resources are in a dialectical unity, to which equal importance should be attached. 6.4 Take Effective Measures to Enhance the Harmonious Development of Exploitation and Protection Only by increasing the weight of science and technology in exploitation and protection, effectively lightening the load of the ecological environment and fully preventing and controlling ecological environment pollution of places bearing resources of tourism and leisure sports, can we promote the orderly, healthy and safe development of tourism and leisure sports.

However, the designer reduces the structural cost without taking into account uncertainties concerning material properties, geometric dimension and loading.
Suitable geometry, material properties and loads are assumed, and an analysis is then performed to provide a detailed behavior of the structure.
Over the last ten years there has been an increasing trend in analyzing structures using probability information on loads, geometry, material properties, and boundary conditions.
In the structural analysis of engineering design, there exist uncertainties in loading, material properties, geometry, and environmental conditions.

It can be indicated that some materials which can react with NaOH go into the aqueous phase after the reaction of NaOH solution with Daqing crude oil for a short time (1d), so that the interfacial active substances contained in the oil phase are less then that in Daqing model crude oil leading to the increase of interfacial tension.
