| 英文摘要 | Since their use in the study of charged particle motion in the 1960s, Euler potentials (alpha, beta) have been widely employed as magnetic field coordinates in both space plasma and fusion plasma studies. People related them to magnetic vector potential A via the relation A = alpha del beta subject to gauge condition A . B = 0 (B is the magnetic induction). For a given magnetic field, the Euler potentials are often constructed with the relation B . Delta S = Delta alpha Delta beta on a surface that crosses the field lines, where Delta S is the area-element surrounding by two line-elements corresponding to the changes in alpha and beta, then mapping the values of alpha and beta along field lines into space. In this short paper, we show that in the presence of field line-aligned currents, the mapping does not work and the orthogonality gauge condition is not satisfied. |
