The factors influencing the measuring precision are also analyzed. Then  the algorithm is adopted to fit curves. Experimental results indicate that the singular value decomposition is very precise  for its error sum is 1.1102V  and the squared error is 2.8mV. Moreover  for phase angle measurement  measured six times in same direction  the squared error is 24 (1). The method based on SVD can satisfy the system precision requirements of curve-fitting north seeking systems. 2011 IEEE.   Multi-wave mixing Autler-Townes splitting in the five-level atomic system 期刊论文 SCIENCE CHINA-PHYSICS MECHANICS & ASTRONOMY, 2011, 卷号: 54, 期号: [db:dc_citation_issue], 页码: 1600-1607 作者:  Wu ZhenKun;  Li PeiYing;  Zhang ZhaoYang;  Sang SuLing;  Wang RuiMin 收藏  |  浏览/下载：4/0  |  提交时间：2019/12/10 four-wave mixing  Autler-Townes splitting  six-wave mixing  multi-dressed states   Enhanced or suppressed six-wave mixing in a five-level atomic system 期刊论文 CHINESE PHYSICS B, 2011, 卷号: 20, 期号: [db:dc_citation_issue] 作者:  Song Yue;  Dai Guo-Xian;  Fu Yu-Xin;  Zhao Jin-Yan;  Wang Zhi-Guo 收藏  |  浏览/下载：9/0  |  提交时间：2019/12/10 suppression  six-wave mixing  enhancement  electromagnetically induced transparency
