Considering multiple center patterns, the center of administration, economy, trade, science and education, etc. were moved into the new village, which led to forming a new center and an old one.
After analyzing the value characteristics of Daliangjiang village, conclusion can be made that it is an ancient village with strong stone culture characteristic on the basis of investigating the materials of Daliangjiang Village’s nature, geography, manners and customs, traditional architecture’s characteristics, etc.
To analysis the buildings from angle of age, style and features, quality, etc., it has some certain protection value, such as history, science, arts, etc., which can reflect the villages’ historical style and features and local characteristic.
In order to show historical and cultural characteristics and traditional style and features of Daliangjiang village, the contents of protection planning include Material Cultural Heritages and Intangible Cultural Heritages.

The simplest virtual reality system is consisted of sensors, virtual reality controllers and 3D model libraries, the sensors are the interface of the system, the user's actions will be captured by the sensors, and the corresponding feedback signal will be perceived by the sensor signal to the users; the 3D model libraries are constituted of the 3D models, virtual reality controls construct the corresponding virtual environment combined with 3D library materials, by the access of the users’ demand, and updated the generate environment based on the user's behavior.
Device simulation, because of its stringent requirements, the chemical equipment often can difficultly be felt, we should use virtual reality technologies to model their materials and dimensions, and use advanced rendering tools in the generation of the scenarios; 2.

A variety of materials have been used in pilot tests, including iron, peat, and bone char.
Essentially, these materials either absorb the metals or precipitate them, similar to soil stabilization and precipitation technologies.
Acknowledgements The study was supported by the scientific and technological project of construction of Gansu Province (JK2010-67) and the “Western Light”Training Programme funded projects of Chinese Academy of Sciences(Y028A21001).

Experimental Procedure Material used in this experiment is a steel for general structure, SS330 (JIS).
If we observe the diffusion pattern during fatigue test of an object material and obtain the coefficient S from Bs - N relation as shown in Fig. 9, we can estimate fatigue life Nf of the material using Eq. (7).
We made an experiment using the same specimen and material as Fig. 1 with unknown stress amplitude.
