Linear polarization active antenna is advised to receive low frequency and broad frequency band wave. The relationship between their characteristic parameters are concluded from the relationship between linear polarization wave and elliptical polarization wave together with the concept the polarization graph of elliptical polarization wave, and can be used as the theoretical base of receiving elliptical polarization wave by linear polarization antenna and the measurement of energy density and polarization parameters of elliptical polarization wave.

The theory of electrochemical Evans diagrams of sulphide mineral flotation system has been set up by means of the electrochemical principles and measurements of corrosion Evans diagrams and the electrochemical mechanism of flotation system of silver minerals has been elucidated.

The optical potential of a nucleon in the nuclear medium is identified with the nucleon self-energy. The real part of the RMOP is evaluated in the DBHF approximation by adopting the decomposition of G = V + AG , and the imaginary part is contributed by the imaginary part of the second-order G-matrix exchange diagram.

For improvement of the theory, the two particle polarization diagram contribution to th e imaginary part of the deuteron microscopic optical potential is studied.

We let only the Hartree-Fock self-energy of nucleon represent to be the real part of the microscopic optical potential and the fourth order of meson exchange diagrams, i. e. the core polarization represent the imaginary part of microscopic optical potential in nuclear matter.

We obtain for the lowest order hadronic vacuum polarization graph and using data only.

In the Abelian case, the contribution comes only from the vacuum polarization graph, whereas in the non-Abelian case, contributions come from the vacuum polarization graph and the two triangle graphs.

In this paper, the two particle Green's function is introduced. When the direct interaction between two nucleons is neglected, the first and second order mass operators of two particles are the sum of those for each particle. The nucleon microscopic optical potential is calculated by applying nuclear matter approximation and effective Skyrme interaction. Then the deuteron microscopic optical potential (DMOP) is calculated by using fold formula. For improvement of the theory, the two particle polarization diagram...

The relativistic microscopic optical potential, mean free paths and Schrodinger equivalent potential of nucleons at finite temperature in nuclear matter are studied based on Walecka's model and thermo field dynamics.

Potentiostatic weight loss tests and cathodic Tafel extrapolations were carried out to establish the polarization curves of 1Cr13 and 0Cr18Ni9 stainless steels in simulated occluded solutions.The effects of external surface on the potential of occluded cell (O. C.) were also superimposed on above diagrams from which the hydrogen evolution rate and corrosion rate of O.C. were clear. It was found that hydrogen depolarization occurred within O. C. as the pH value of occluded solution decreased below the critical...

Potentiostatic weight loss tests and cathodic Tafel extrapolations were carried out to establish the polarization curves of 1Cr13 and 0Cr18Ni9 stainless steels in simulated occluded solutions.The effects of external surface on the potential of occluded cell (O. C.) were also superimposed on above diagrams from which the hydrogen evolution rate and corrosion rate of O.C. were clear. It was found that hydrogen depolarization occurred within O. C. as the pH value of occluded solution decreased below the critical pH value, but the velocity of hydrogen depolarization was only 0.057% and 2.3% of corrosion rate inside O.C. for 1Cr13 and 0Cr18Ni9 stainless steels respectively. It was shown that the "accelerating corrosion effect" of O.C. was caused by the passive active transition accompanied with the sudden increase in the potential difference between O.C. and external surface.
