Resistivity as a function

System flow resistance as a function of flow rate is needed to select the proper fan size. For calculation of system pressure drop see References 5—8. The resistance pressure curve for a typical system (Fig. 4a) shows that the pressure required to force air through the system increases with the flow rate.

Fig. 5. Electrical resistance as a function of the temperature at the indicated magnetic fields for a single microbundle of carbon nanotubes. The solid line is a fit using the two-band model for graphite (see inset) with an overlap A = 3.7 meV and a Fermi level right in the middle of the overlap (after Langer et at. l9 ).

The data show corrosion resistance as a function of acid composition, concentration and temperature. Since the data are mostly derived from laboratory corrosion tests in pure solutions, they should not be taken as a firm indication of performance in service. 

In situ measurements of electrical sheet resistance provide another clue to the composition of the films. A plot of the sheet resistance as a function of dose is shown in Figure 8. The decrease in sheet resistance trails the loss of carbon and oxygen by a factor of 10 in terms of ion dose and reaches a limiting value of 2xl04 uto-cm. This is two orders of magnitude greater than the lowest value measured in the laser-exposed material, at least qualitatively consistent with the relative purity of the metals in each case.

FIG. 9. The tunnel resistance as a function of tip movement is shown in (a). Positive z displacement corresponds to a decreasing tunnel junction width, and the jump in conductance at is associated with point contact. The inset figure shows the degree of reproducibility associated with the experiment which employed an Ir tip and substrate. The gradient associated with the attractive force between the two electrodes was measured simultaneously as shown in (b). (From Ref. 66.)... 

Figure 11 shows the spinning curve for a resist as a function of spinning speed for three concentrations (this is the same polymer as used in Figure 11). Note that the slope of these curves is the same as in Figure 10. It...

Apparent activation energies for the degradation reaction was calculated using specimens 28 and specimens 30, 31 and 32, A value of -7 kcal/mol was obtained. This evaluation was based on the variation of resistance as a function of temperature. A similar value was obtained also with specimen 11 (Table I) after It was exposed to salt spray test (100 hours). 

A set of experiments was performed at variable droplet sizes. The graph in Fig. 4.7 shows the dependence of the normalized (by Kint/a) osmotic resistance as a function of the oil volume fraction. The normalized values fall onto a single curve within reasonable experimental uncertainty. The results were compared to the normalized data obtained by Mason et al. [7] in the presence of surfactants. These latter are represented as a solid line that corresponds to the best fit to the experimental points (Eq. (4.18)). It is worth noting that the normalized pressures in solid-stabilized emulsions are much larger than the ones obtained in the presence of surfactants.

The discussion given in BS 4618, Sections 2.3 and 2.48 on design data for plastics applies in principle to rubbers, and stresses the advantage of measuring resistivity as a function of temperature, humidity, electric stress and time of electrification. 

Recently, a detailed study4,5 of AB02 compounds confirms that AgFe02 has the CuFe02 (delafossite) structure. The cell dimensions, determined with a Guinier camera, are found to be a = 3.0391 2 A. and c = 18.590 2 A. Single crystals are used to measure resistivity as a function of temperature.6 Silver fer-rate(III) exhibits semiconductor behavior with an activation energy of 0.7 e.V.
