◆ The potential gradient at any position in an electric field is the change of potential per unit change of distance in a given direction. 电势的定义,来源于能量/功,所以我们可以通过计算potential difference,用charge乘以potential difference就可以得到work done. 5 电势和电场的关系 The electric field ...
Since a close relationship exists between these various disturbing effects and the local values of the potential and potential gradient, a knowledge of these quantities are of prime importance in evaluating the feasibility and performance of this power transmission technique. 展开 ...
Objective To calculate the electric field and potential distribution of multi-needle electrodes in conductive media(biological tissues) by integral equation approach. Methods According to the electric potentials of multi-needle electrodes, discrete equations based on unknown linear current density were establ...

High magnetic fields (up to 17.6 T) in combination with large magnetic field gradients (up to 25 T/m) were successfully utilized in pulsed field gradient (PFG) NMR studies of gas and liquid diffusion in nanoporous materials. In this mini-review, we present selected examples of such studies ...
Using the first-principles full-potential linear muffin-tin orbital method in the atomic sphere approximation, we have calculated the electronic structure of the intermetallic compound , and evaluated the electric field gradients (EFGs) at all of the three inequivalent positions (two Hf and one Fe...
Existing grand-potential based multicomponent phase-field model is extended to handle systems with interstitial sublattice. This is achieved by treating the concentration of alloying elements in site-fraction. Correspondingly, the chemical species are distinguished based on their lattice positions, and thei...
This paper proposes a random tree algorithm based on a potential field oriented greedy strategy for the path planning of unmanned aerial vehicles (UAVs). Potential-field-RRT (PF-RRT) discards the defect of traditional artificial potential field (APF) alg
On the other hand, an increase in γRa causes the temperature gradient in the center of the enclosure to decrease, and the whole fluid cavity tends to a uniform temperature. Figure 4 illustrates local Bejan number (Be), entropy generation maps due to heat transfer (Sθ), and fluid ...
