On the other hand, it can also be expressed in the terms of the translation gauge field strength and therefore is covariant under general coordinate transformations. 同時(shí)，引力場(chǎng)的能量動(dòng)量又可以表示為平移規范場(chǎng)強的二次齊式因而在廣義坐標變換下協(xié)變。
The equations of the electric field of elliptic linear electric charge are solved by using coordinate transformation, and some discussions on them are given. 摘要通過(guò)坐標變換求出了橢圓形線(xiàn)電荷的軸向場(chǎng)強及電位分布規律，并對結果進(jìn)行了分析討論。
