Simulation Permeable Porous Materials of the Complex Shape During Radial-Isostatic Compression

Electrophoretic deposition (EPD) is a good method in the fabrication of the coating materials. Its processing parameters are easy to be operate. It is a nonbeeline process and can be used in the deposition on complex shape and porous surface. It has been widely used in many ways. This paper reviews the principles and fabrication steps of EPD and points out the influencing factors. The developments of EPD in the fabrication of materials, such as solid surface coatings, porous structure materials and gradient materials, are introduced in detail. The future of the application of EPD is also discussed.

Comprehensive Study

Various porous materials are widely used in various industries, such as chemical, metallurgical, energy, light, food, etc. Therefore, a comprehensive study of their structure and physical and technical properties is of great scientific and technological importance. The article presents the results of determining and studying the volume and density of porous sample materials using a new experimental method. The determination of the volume and density of waterproof samples of any complex shape can be easily determined on the basis of Archimedes ' law. However, it is impossible to determine the volume and density of porous water-absorbing samples of complex shape directly using this law. The article presents new experimental methods (methods) for determining the volume and density of such porous samples of complex shape. The results of experimental work carried out using the proposed new methods are presented and analyzed.

The Magnetic Field

SummaryMeasurements of the radial velocities and magnetic field strength of β CrB were carried out. It is shown that there is a variability with the rotation period different for various elements. The curve of the magnetic field variation measured from lines of 5 different elements: FeI, CrI, CrII, TiII, ScII and CaI has a complex shape specific for each element. This may be due to the presence of magnetic spots on the stellar surface. A comparison with the radial velocity curves suggests the presence of a least 4 spots of Ti and Cr coinciding with magnetic spots. A change of the magnetic field with optical depth is shown. The curve of the Heffvariation with the rotation period is given. A possibility of secular variations of the magnetic field is shown.
