| 摘 要： | 针对带不确定性的平差算法（least-square with uncertainty，ULS）中不确定度的选择问题，提出类L曲线法，并在位错模型中进行实验，解算位错参数。通过与LS和TLS的解算结果进行比较发现，ULS的解具有更高的精度，最高优于LS和TLS近60%。

| Abstract: | This paper proposes a similar L-shaped curve method processing uncertainty selection problem of ULS, and then experiments on the dislocation model and calculating dislocation parameters. Finally, comparison of the result of ULS with those of LS and TLS, shows that ULS has higher precision, increased by nearly 60% over LS and TLS. |
