摘要： 提出了一种用于精确模拟冷原子云的三维图像方案，这个方案比先前通过探测激光的方法所获得的二维图像更加直观和立体。该研究实现了冷原子云的模拟，捕获原子的数量约为108。原子云是几何三维形状，Rx=1.06 mm, Ry＝1.06 mm, Rz＝0.57 mm, 具有不同半轴长度的三轴椭圆体。

Abstract：We propose a scheme for accurately simulating of the three-dimensional image of cold atomic cloud, which is more intuitive and stereoscopic than former two-dimensional image by probe laser. We have realized simulating of cold atomic cloud. The number of trapped atoms is about 108. The atomic cloud is about the geometric three-dimensional shape. Tri-axial ellipsoid with distinct semi-axis lengths Ｒｘ＝1.06 mm, Ry＝1.06 mm, Rz＝0.57 mm, and the three-dimensional image of cold atomic cloud was simulated for the first time.
