- The Rotation Curve of Our Galaxy 银河系自转曲线
- To make a rotation curve one calculates the rotational velocity of stars along the length of a galaxy by measuring their Doppler shifts, and then plots this quantity versus their respective distance away from the galactic center. 沿着银河的长度通过测量它们的多普勒变换计算星系的旋转速度的旋转曲线,然后绘出它们分别远离银河中心的距离。
- Galactic rotation curves, which illustrate the velocity of rotation versus the distance from the galactic center, cannot be explained by only the visible matter. 银河旋转曲线，就是用图例说明相对星系中心距离的旋转速度，仅靠可见物质解释不了这个速度。
- The next point to the right is the mass in galaxies, which moves to the position of the higher dot if we include the dark matter inferred from rotation curves. 右边下个点是银河的质量如果我们包括从旋转曲线推论出暗物质移到更高点的位置上。
