| 摘 要： | 附加二次相位因子（ASF）是影响长波授时精度的主要因素,而其理论计算复杂、实测成本太高,不便于工程推广。本文选取华北平原区域为研究范围,提出一种简单高效的ASF修正方法———建立对应的ASF数据网格,采用插值算法进行ASF修正研究。通过对ASF数据网格的验证和分析,得到了和预期效果相一致的实验结果。实验结果表明：建立区域性的ASF数据网格有利于快速地修正ASF误差,便于实际工程应用。

| Abstract: | The Additional Secondary Factor(ASF) is the major factor affecting accuracy of long-wave time service.while its theoretical complexity and experimental costs too high,not easy to project promotion.The area of the North China Plain was selected as a research example,and a new method which establish ASF data grid and use interpolation algorithm to study the ASF correction was presented.The results obtained are consistent with expected.The experimental results show that: Established regional ASF data grid can ... |
