1·The results suggest that calcium antagonist be effective in treating AHC.

提示钙离子拮抗剂对本病治疗有效。

2·Methods the National Management Information System for Disease Reporting software was applied to gather epidemic data, and descriptive epidemiological analysis was conducted on AHC.

方法利用来自国家疾病报告管理信息系统的疫情资料，对(AHC)进行描述性流行病学分析。

3·Experimental research comparing with AHC based on standard LMS, demonstrated that ASLMS-based AHC, which has faster convergence and smaller distortion, owe more advantages in the parameter setting.

与基于标准LMS算法的AHC对比试验研究阐明了基于ASLMS算法的AHC在参数设置上有优势，且收敛速度更快、波形失真更小。
