| 摘 要： | 对目前台站使用的两类模拟石英管(SSY-Ⅱ)、数字石英管(SS-Y)与因瓦钢棒(SS-Y)三种伸缩仪的观测结果进行了对比分析,结果表明,模拟石英管伸缩仪( SSY-Ⅱ)、数字石英管伸缩仪(SS-Y)记录应变固体潮潮汐曲线均清晰、圆滑、抗干扰能力强、观测精度高；含铌因瓦钢棒伸缩仪( SS-Y)潮汐记录曲线不光滑,似乎叠加有某种干扰波,潮汐曲线畸变,观测精度不及上述两种石英管伸缩仪.

| Abstract: | The contrastive analysis of the observational results with the extensometers of analog quartz pipe,digital quartz pipe and invar rod used now at stations are made.The results from the analysis show that the curve of the strain solid tide recorded with the two kinds of quartz pipe are clear,smooth,and they have good noise immunity,high observation accuracy,and the curve recorded with invar rod is not smooth,superposed some noise wave and distortion,so its precision is low. |

| Keywords: | strainmeter extensometer with analog quartz pipe extensometer with digital quartz pipe extensometer with invar rod strain solid tide |
