Nowadays, hot issues are likely become bipolar or multipolar after heated discussion on the Internet. This article is focused on the study of the phenomenon and establishes a public opinion model with the considerations of individual heterogeneity and dynamic conformity. At first, this article introduces the dynamic changing function of an individual&rsquos ...

The Sun and many other light sources produce waves that are randomly polarized see Figure 4. Such light is said to be unpolarized because it is composed of many waves with all possible directions of . Polaroid materials, invented by the founder of Polaroid Corporation, Edwin Land, act as a polarizing slit for light, allowing only in one direction to pass through.

· Metallic are polarizable. The polarizable property can be used as the basis for metallic exploration . By use of induced method, we observed phenomenon that occur in metallic material. In this study, physical events were observed that occur in rocks containing manganese using induced method.

Polarization also occurs by the refraction of light in a plane perpendicular to the surface. The of refracted light is often demonstrated by Nicol’s prism or Iceland Spar, a rare form of the mineral calcite. It refracts incident light into two different paths that are …

Brit. polarisation is a property of transverse waves which describes the orientation of the oscillations in the plane perpendicular to the waves direction of travel.This concept is used in areas of science and technology dealing with wave propagation, such as optics, seismology, and telecommunications.

According to the MP model, is related to both the chemistry of the surface and to the pore throat geometry Titov et al. 2004 Bucker & Hordt 2013. As we showed earlier, dissolution changes the grain geometry see for example Fig. 5 and the change in the formation factor, and therefore also the pore space ...

Sulfide are a group of compounds with the presence of sulfur. This group’s most abundant and economically members are pyrites, pyrrhotite, chalcocite, galena, sphalerite, and the group of copper sulfides . Resistivity and Induced IP methods, which play an essential role exploration, showed great success in sulfide exploration.

1 The polarization of the Stern layer coating the mineral surface is playing an important role as first shown by Schwarz 1962. 2 The Maxwell–Wagner polarization represents the blocking of the ions at dielectric boundary layers in heterogeneous materials like porous media Maxwell 1892 Wagner 1914.

Typical measurements linked to exploration application. For mining exploration applications, the method and equipment to use depend on how the precious metal is concentrated or disseminated in rocks, on the size of the orebody but also on its depth. Depending on its depth, lens type orebody can be detected by 2D or 3D tomography which is completed with TIPIX or VIP range transmitters ...

To cut the refractions, Fishermen, Skiers, motorists, sportsmen need special sunglasses. In the production of these special sunglasses of light is used. Many photographers use polarizers to capture the perfect scene. microscopes are used in geological studies to identify the . In infrared spectroscopy.

A dielectric or dielectric material is an electrical insulator that can be polarized by an applied electric field.When a dielectric material is placed in an electric field, electric charges do not flow through the material as they do in an electrical conductor but only slightly shift from their average equilibrium positions causing dielectric .
