The RMS slope is obtained from the angular width of the DALLAS light-scattering pattern.

均方根斜率是从DALLAS光散射图象的角宽得到的。

The scattering pattern not only contains the information of particle size, but also of their shape. Particle shape analysis using light scattering is still in the initial stage.

光散射谱中同时含有反应颗粒大小和形状的信息，而光散射法用于颗粒形状的表征尚处于起步阶段。

From the pattern of this scattering, and from the sizes of the asteroids (which tells you how fast they will scatter), it is possible to calculate the date of the original collision.
