Fig. 2 Paste on the accelerometer. 2.5 Data Analysis The present vibration determination material must first save in the SVAN 948 four channels analyzers, after and so on returns to the laboratory again the data which records the SVAN 948 four channels analyzers, passes on to the SVAN 948 analyses software, carries on the analysis.
The analysis material can vibrate a decibel value including the sole axial 1/3 octave frequency band correspondence, the biggest record inspires to move a decibel value and the closed region (1~80 Hz) can a decibel value.

Construction and Building Materials The builders of the monasteries mainly dealt with the question of water drainage from the site and later on the structural solution of the foundations on wet subsoil.
When expensive imported materials were employed, they probably were either spolia (reused building materials) or leftover from other buildings (Fig. 3).
A key challenge for the structural recovery was climate and static ensurance of the buildings.

Introduction An increasing number of environmental regulations, the new development of new materials with environmental friendly properties are recognized as an effective method toward the goal of environmental pollution.
Therefore, there have been many efforts to replace petrol-based materials with natural-resource based materials.
During recent years, the use of natural fibers materials as reinforced polymer composites has become the hotspot of among researchers, such as flax, jute, hemp and ramie [1-5].
The sisal fiber is not only a widely used natural resource and one of the major natural fibers produced worldwide, but also is a very interesting low cost, renewable engineering material.
Materials and Experiment Materials The sisal fiber used in the experiments was supplied from the producers’ Guangxi Sisal Company in Guangxi province in China.

Materials and methods Soil samples and their parent rocks.
The variations of electrochemical properties in our results are also induced by these reasons, especially by differences in parent materials.
Surface potential is an important parameter in fields such as colloid and surface chemistry, nano material, soil science, ecology, environment science, biology and chemical engineering, so it has been an important issue ever since.
Physical weathering dominates in the soil-forming process of purple soil, and their parent materials and rocks showed that other indicator characters of soil genesis were lower free iron content and clayization coefficient, weak loss or enrichment of elements, higher silt-clay ratio and the similarity of silica-alumina ratios between soils, parent materials and bed rocks [22].
