| 7. | A method of selecting mges that can be deleted is proposed . because too much mges " deletion will result in an ineffective model , mges can not be deleted totally at one time
提出一种线性稳态数据协调中的显著误差变量选择删除算法，以保证在显著误差变量个数过多的情况下原有模型的有效性。 |
| 8. | For the existing test based on measurement residual , the main problem is that the data reconciliation procedure tends to spread the gross errors overall the measurements , which results in the detection failure
通过构造一个基于测量值比例关系的f统计量，并与约束残差统计量相结合，对稳态过程中出现的显著误差进行检测。 |

并且通过对显著误差进行逐步的幅度补偿，再采用mt （测量残差检验）法找出候选显著误差集，避免了投影矩阵的计算。 |
