In chapter three,we have derived a generalized dual London equation for the Abelian "electric" field A_μfrom the effective dual Abelian-Higgs model.The approximative result and the numerical simulation result as well as their figs were shown via solving the dual Abelian-Higgs model with different methods.Hereby the vortex solution of the chromo-electric field and the vortex energy density were also discussed.Finally,we have studied the dual Abelian-Higgs model with additional vacuum constant,and have unpuzzled the vacuum constant corresponding to the bag model.When the quark sources is introduced, the vacuum constant in the MIT bag model is proportional to the quartic of the monopole mass.

Because RFCA in a bipoiar fashion can enlarge lesion surface area without increasing the depth, and its particular lesion distributions involved the electrode/tissue interface and the part between the two adjacent electrodes, there is much opportunity to hit the target in bipolar fashion so long as the orientation of the pathway or the any part of reentant circle is not parallel to the electrode-connecting line, whatever at any angle.

因为双极消融法比常规单极消融法有更大的消融面积但不增加深度，而且其组织损伤分布于两电极与组织的交界面和两电极之间区域，所以只要旁道或折返环路的任何部位的走向与两电极的连线不相平行，在任何夹角下双极消融均比单极消融有更多的击中机会。

All these characteristics can extend frequency band , reduce antennaelectric size and improve impedance characteristics.
