英语翻译
1,this direction is a compromise that points away from the system of charges q1 and q2
2,the angle α is below the x-axis
3,But a more fruitful way to visualize the repulsion between A and B is as a two-stage process
4Then body B,as a result of the charge that it carriesm senses how space has been modifued at its position.The response of body B is to experience the force F.
5thus the electric field is the intermediary through which A communicates its presence to q0
6if the field E at a certain point is known,rearranging Eq(等式) gives the force F experienced by a point charge q0 placed at that point.This force is just equal to the electric field E produced at the charge distribution to be fixed.
7if the souce distribution is a point A
8E is produced by q but acts on the charge q0 at point P
9each component of E at any point is in general a function of the coordinates(x,y,z) of the point.
10 at each point P,the electric field set uo by an isolated positive point charge q points directly away from the charge in the same direction as r
11 give the free charge a net motion
12 the magnitude and direction of v,and hence its vector components,vary from point to point in the atomosphere.
13 ...(主句),provided the dimensions of the object are much less than the distance from the object to the field point.
都是物理的句子,尽量翻译标准些吧~
还有一个：identify and set up这两个应该翻译成物理中的什么?

1,这是一个妥协的方向指向远离收费Q1和Q2系统
2,α低于X轴的角度
3,但将A和B之间的斥力更有效的方法是一个两阶段的过程
4体B,由于电荷,它carriesm感觉空间已经modifued在它的位置上.体B的反应是经验的力F.
5thus电场是通过它传达其存在的中介影响
六场在某一点是已知的,重新排列的情商（等式）给力F的放在这一点上一个点电荷Q0的经历.这个力等于电场产生的电荷分布是固定的.
七点源分布
8E Q但行为上产生的电荷Q0在点P
在任何点的E 9each组件是在一般的坐标（x,y,z的函数）的点.
10在每个点的P,由一个孤立的阳性点电荷电场建立直接指向远离电荷在同一方向的R
11提供自由电荷的净运动
12的大小和方向,V,和它的分量,从点到大气中的点.
13……（主句）,提供对象的尺寸远小于从物体的距离的点.
确定和建立
