Besides the detect depth and size of karst caves required by the construction of expressway, various physical methods also have specific requirements for their applicable use such as the lithology, development degree of karst and spatial distribution, karst caves with or without filled materials, and the content of the materials.
Table 1 List of Resistivity of different materials in the study area [2,3,4,6,8,11] Materials Resistivity Materials Resistivity Carbonaceous marlstone <200 Clay, fine sand, gravel, gravelly soil <150 Dolomitic marlstone >600 Carbonaceous dolomitic marlstone <200 Limestone 200-2000 Unit: [Ω·m] 2.3 Principles of high density resistivity method High density resistivity method is based on electric difference of rock-soil mass when apply the electric current to the strata,to infer the underground spatial distribution of resistivity anomaly shapes[11].
These can be inferred that karst caves filled with high resistivity materials are developed at these locations.

Due to large aspect ratio and skin effect, fiber materials are more effective to improve electromagnetic shielding effectiveness than conventional powder materials.
However, the dispersion of fiber materials is difficult in cement- matrix composite because the fiber cling to each other easily [6-7].
The nickel fiber (diameter 8 µm, length 6 mm) was obtained from Western Metal Materials Co.

Introduction Furfural, one kind of important light industry and chemical raw materials, can be hydrolyzed in acid medium by some renewable resources, such as corncobs, begasses, grain hulls, and so on.
Ultrafine CuO-CaO/SiO2 catalysts by solution-gel method can be prepared by inexpensive raw materials, simultaneously exhibit excellent catalytic activity and selectivity.
(2) Analysis of catalyst Most of the prepared copper-based catalyst has high activity, and the presence of Ce, Co metal can improve the selectivity of the conversion rate of raw materials and products.
We believe these research and applications will be compatible with the development of chemical engineering, and will greatly promote the development of green process technology, as well as the use of inferior raw materials, alternative raw materials and renewable raw materials.
