Diffusion Tube

The relationship between current ratios and electron diffusion coefficients for the Townsend-Huxley experiment is reanalysed with the assumption that diffusion can be represented by two coefficients DT and DL for diffusion transverse and parallel respectively to the applied electric field. When the new formula is used to interpret previous experimental data obtained with a diffusion tube of length 2 cm, the derived values of DT/fl become independent of pressure (fl being the electron mobility). For longer diffusion tubes (~ 6 cm), current ratios are insensitive to DL and the results differ insignificantly from those obtained using the formula previously derived on the assumption that diffusion is isotropic.

In this paper, we study the twist of the nematic liquid crystal molecules under the applied electric field. The dynamic equation of the twisted molecules is derived. It is proved to be a kind of sine-Gordon (SG) equation. We obtain the breather solution of the equation and confirm that the deflection angles of the twisted molecules can distribute in the form of breathers. We give the relationship between the molecular deflection angle and the breather frequency, and discuss the effect of electric field on breather shape and breather frequency.

The Relationship

Based on the theory of classical piezoelectricity, the relationship between the generation of multiple piezoelectric effect under applied electric field and boundary conditions is analyzed. The generating process of multiple piezoelectric effect is elaborated and the formulas of secondary direct and tertiary converse piezoelectric effect are deduced. The displacement or voltage generated by primary converse, secondary direct and tertiary converse piezoelectric effect is calculated by using coupled-field analysis function in the Finite Element Analysis software-ANSYS. Experimental research of multiple piezoelectric effect under applied electric field is performed through PZT-5 stack. The experimental result verifies the existence of multiple piezoelectric effect. Experimental data shows that voltage and displacement generated by secondary direct and tertiary converse piezoelectric effect respectively are linear with the applied voltage. Both the simulation and experimental results prove that the theoretical analysis is accurate.
