HIGH TEMPERATURE LIMIT FOR CERAMICS ON THE COPPER
FOR TRANSPORT SYSTEMS BASED ON MAGNETIC LEVITATION


Annotation: The article talked about the properties of high-temperature ceramics tocopper for transport systems on a magnetolevitation basis.
Introduction: On the method of secondary quantization in the diagram technique <1>for the four Fermion interaction with potential with a solid core of <2-3> considered the phasetransition at high temperatures. Summation of diagrams of perturbation theory was in its mostgeneral form. The transition to the high temperature limit is produced directly in the mainequation of superconductivity for the energy gap, which causes this equation to a linearintegral equation. Most solved exactly. Twice the value of core wired with lattice parameterfor the number of compounds on copper. Shows the results of applying this approach invarious critical temperatures.
Objective:Development of the theory of high-temperature ceramics to copper fortransport systems on a magnetolevitation basis.
Method: In order to achieve this goal have been used the method in the diagramtechnique <1> for the four Fermion interaction with potential with a solid core of <2-3>. Twicethe value of core wired with lattice parameter for the number of compounds on copper. Latticeparameters, etc. taken from the book <4>. The transition to the high temperature limit isproduced directly in the main equation of superconductivity for the energy gap, which causesthis equation to a linear integral equation. Most solved exactly. Definition of energy formationbenefit this condensate is produced by calculating the correlative thermodynamic potential.
Results:
1. the exact solution is obtained for the basic equation of superconductivity for energygap in high temperature limit in volume, distributed (focused) on a sphere with some radiuswhich is in back proportional to the critical temperature; the calculation of correlation forthermodynamic potential showed energy advantage formation such a condensate;
2. the exact solution of the basic equation of superconductivity for energy gap allows awhole series of further decisions with less in an integer times temperatures as in table 18 inbook <4>;
3. presents the results of detailed calculation of parameters for four types of high-temperature ceramics on copper at different critical temperatures; the effective interactioncoupling ge has order of the Fermi weak interactions coupling in three orders of magnitudeweaker than the electromagnetic one.
Conclusion:
As a result of the research was developed the theory of high-temperature ceramics tocopper for transport systems on a magnetolevitation basis. Superconducting condensate islocalized at the surface of spheres of a discrete radius which is in inversely proportional to thecritical temperature. Found that the pit depth ratio U = ge/Re to the critical temperature isincorporated in all cases to a constant value equal to 0.880 within allowable dispersion of 0.11.
