In noncommutative scalar field theories, the appearing of nonplanar diagrams is related to permutation symmetry of field functions in the interaction Lagrangian, while in NCQED we can not arbitrarily change the positions of field functions in the interaction Lagrangian because different positions of the field functions correspond to different representations of the gauge group.

這里需要特別指出的是NCQED的非平面圖產生的原因與非對易標量場根本不同性爱一级毛片，非對易標量場非平面圖的產生是和相互作用拉氏量密度中場函數間位置的置換對稱性有關，而在NCQED中我們不能隨便交換相互作用拉氏量密度中場函數的位置亚洲欧美日韩视频二区，因為場函數的不同位置對應著規(guī)范群的不同表示91人妻视频nnnnnn。

The contributions to the induced current and voltage by various electromagnetic field components, such as the vertical electrical field, the horizontal electrical field and the horizontal magnetic field, are compared in this paper in terms of integral of Green function and superposition theorem.
