The experimental results show that measuring fossil track projected lengths is more powerful to reveal palaeotemperature and is very simple.

您可以通过保证范围(每个投影长度单元对应多少像素)在 x 和 y 方向上相同(或接近)来防止这种情况发生。
You can prevent this by making sure the scale (how many pixels correspond to each projected unit of distance) is the same (or close) in both the x and y directions.
Furthermore the source number estimation method based on theory of MDL and the algorithm of MUSIC based on sub-space projection technique are also introduced briefly.
