An error has been found in equation (9) that has caused difficulty to some readers. The term which reads 0.214*M should read 0214*sqrt(M). In addition, there is a typographical error in the title: It appears as “conductivity on shaly sands”.

Abstract The paper presents a changeability of electrical conductivity of jet fuels in distribution. Author described the methods used to prevent the formation of the dangers of static electricity. Research was carried out on two basic fuels used worldwide to power engines in civil (Jet A – 1) and military aircrafts (F – 34), during real fuel supplies in aviation military unit. Results of influence of temperature on the electrical conductivity of jet fuel are presented.

Influence Of Temperature On

In boreholes, temperatures vary and to extract hydrocarbon saturation from conductivity measurements, the influence of temperature on water and rock conductivities must be accounted for. The mobility [Formula: see text] of the counter‐ions due to clays and the electrical conductivity of pore‐filling brine show large changes with variation in temperature, whereas the microgeometry of the pore space exhibits negligible change. Using this idea, the temperature dependence of [Formula: see text] is extracted using data on dc electrical conductivity of shaly sands (σ) containing varying amounts of clay. The mobility of [Formula: see text] counter‐ions is found to vary approximately linearly with temperature. This explicit relationship is tested by comparing the predicted temperature dependence against the measured temperature dependence of conductivity of a set of rocks with high and low clay content. While the rock conductivity shows a large temperature dependence, the resistivity index is less sensitive to temperature. An approximate formula, which is superior to Arps’s formula, for water conductivity as a function of temperature is obtained.

Atomic Form Factor

Temperature affects both elastic and inelastic scattering of electrons in a crystal. The Debye-Waller factor, B, describes the influence of temperature on the elastic scattering of electrons, whereas the imaginary part of the (complex) atomic form factor, fc = fr + ifi, describes the influence of temperature on the inelastic scattering of electrons (i.e. absorption). In HRTEM simulations, two possible ways to include absorption are: (i) an approximate method in which absorption is described by a phenomenological constant, μ, i.e. fi; - μfr, with the real part of the atomic form factor, fr, obtained from Hartree-Fock calculations, (ii) a more accurate method in which the absorptive components, fi of the atomic form factor are explicitly calculated. In this contribution, the inclusion of both the Debye-Waller factor and absorption on HRTEM images of a (Oll)-oriented GaAs crystal are presented (using the EMS software.Fig. 1 shows the the amplitudes and phases of the dominant 111 beams as a function of the specimen thickness, t, for the cases when μ = 0 (i.e. no absorption, solid line) and μ = 0.1 (with absorption, dashed line).
