本文从粒子的轨道理论人手，通过对近900条粒子轨道的具体计算，研究了磁尾粒子在晨昏电场作用下的投掷角变化。

In this paper, the pitch Angle changing of charged particles of the magnetotail under the action of the dawn-dusk electric field is studied by evaluating about 900 trajectories by computer.

由单粒子轨道理论，从分析磁镜场中荷电粒子的受力情况出发，应用计算机数值求解方法模拟了磁镜场中荷电粒子的运动情况。

Motion of charged particles in magnetic field confinement was simulated with single particle approximation. The simulated results differ from those calculated with classical theory.

If de Broglie is correct, we could then model the electron in its orbit not moving as a particle, but let's model it as a wave.

如果德布罗意是对的，那么我们可以在电子轨道中建立电子模型,不是像粒子一样运动，而是像波一样运动。

So, the example that we took on Monday and that we ended with when we ended class, was looking at the 1 s orbital for hydrogen atom, and what we could do is we could graph the radial probability as a function of radius here.
