Therefore, in the "12th Five-Year Plan" of the Ministry of Land and Resources clearly pointed out it is necessary to develop the study of some key problems in the exploration and utilization of Hot Dry Rock and the exploration technology of Hot Dry Rock in the underground 3000~5000 m, such as geological exploration drilling, geophysical exploration, well logging and study of Some key problems and so on.
Meanwhile, the deep fracture deeply cut earth crust, become weak belt, and become the rising channel of mantle material and the heat flow, create good conditions for the base hack, intrusion, convection of magma and formation of Hot Dry Rock, while the deep fracture controls volcanic activity of the basin and the basin basement, and make up the fracture net connected the upper mantle heat source together with fracture in basin.

Median Italy: Territorial Diversity as the Cornerstone of Regional Development Donato Di Ludovico1,a, Pierluigi Properzi1,b and Andrea Santarelli1,c 1 DICEAA - Department of Civil, Building-Architecture, Environmental Engineering, University of L’Aquila, Italy adonato.diludovico@univaq.it, bproperzi@tin.it, candreasanta9@gmail.com Keywords: Median Macro-Region, City Networks, Territorial Settlement Systems, Tourist Systems, Territorial Frameworks, Territory Projects.
In this paper, it shall be considered as a coherent and optimal setting for the development of national and European policies, and in particular for the identification of a Median Macro-region [1] as a key area of Euro-Mediterranean development.
In this interpretive model, the Cities, as hubs of relationship flows, and their networks, as more than a material axis of these flows, become areas of systemic planning.
The objective is to integrate both widespread and local networks (central Italy plays a key role in central Europe along the East-West axis as well as the North-South axis).

Introduction With the rapid development of wireless communication and satellite communication, microwave dielectric materials have been widely used in practical application such as global positioning system (GPS) and wireless local area network (WLAN) technology.
CaTiO3 is widely known as an important microwave dielectric material.
Therefore, ceramic materials with a near-zero τf value can be obtained by a forming solid solution between CaTiO3 and (Li0.5Sm0.5)TiO3.
Experimental Procedure High-purity commercial powders of CaCO3 (99.0%), TiO2 (99.9%), Li2CO3 (99.9%), and Sm2O3 (99.99%) were used as the starting materials.

For the former method, TiC particles are added directly into the coating materials.
Experimental Details In this experiment, the raw materials were prepared by following steps.
Firstly, 50wt% ferrochromium powder, 31wt% ferrotitanium powder, and 4wt% ferrosilicium powder were mixed together as raw materials.
The chemical composition of raw materials is presented in Table 1.
Secondly, the raw materials were well mixed with ethanol and milled for 2 hours.

Magnesium-based alloys containing rare earth metals are widely used in modern industry as structural materials.
Experimental 2.1 Experimental materials In the present experiments, commercial AZ91D magnesium alloy, binary Mg-14.6%Er (mass fraction) master alloy, industrially pure magnesium (99.9%) and zinc (99.9%) were taken as the starting materials.
Appropriate amounts of the starting materials were melted in a graphite crucible in an electric resistance furnace at about 750°C.
Subsequently, the AZ91D-1.5%Er ingots used as the experimental materials were obtained, the main chemical compositions of which are reported in Table 1.
