英文高手 幫幫忙!

Inside the sphere there is no electric field.‭ ‬Where the outside electric field meets the surface of the sphere,‭ ‬the electric field must be normal to the surface of the sphere.‭ ‬Otherwise,‭ ‬the electric field at the surface would have a vector component parallel to the surface which would cause charge to move along the surface,‭ ‬again in violation of our static conditions stipulations.‭ ‬Now,‭ ‬electric field lines that are perpendicular to the surface of a sphere lie on lines that pass through the center of the sphere.‭ ‬Hence,‭ ‬outside the sphere,‭ ‬the electric field lines form the same pattern as the pattern that would be formed by a point charge at the location of the center of the sphere‭

    Inside the sphere there is no "electric" field.‭ ‬Where the "outside" "electric" field meets the surface of the sphere,‭ ‬the "electric" field must be "normal" to the surface of the sphere.‭ ‬Otherwise,‭ ‬the "electric" field at the surface would have a vector component "parallel" to the surface which would cause charge to move along the surface,‭ ‬again in violation of our "static" conditions stipulations.‭ ‬Now,‭ "‬electric" field lines that are "perpendicular" to the surface of a sphere lie on lines that pass through the center of the sphere.‭ ‬Hence,‭ ‬outside the sphere,‭ ‬the "electric" field lines form the "same" pattern as the pattern that would be formed by a point charge at the location of the center of the sphere‭

    在球形裡面沒有电场。 那里外部电场遇見球形的表面,电场一定是正常的對球形的表面。 否則,电场在表面將有傳染媒介組分平行與將造成充電沿表面移動的表面,違反我們的靜止再適應規定。 现在,是垂直的對球形謊言表面在線的穿过球形的中心的电场線。 因此,在球形之外,电场排行形式樣式和將由在球形的中心地點的一個点电荷形成的樣式一样

    這是我在YAHOO!字典裡查出來的

    不過要請你找形容詞啦

    因為我是國語白痴呀

    所以我不知道哪個是形容詞耶
