| 摘 要： | DSQ型水管倾斜仪是“九五”期间推出的数字化地震前兆仪器。据涉县地震台DSQ水管仪延长基线和进一步密封改造后的经验，认为决定观测精度的主要因素除了受台站所在地的地质构造条件、观测场地形地貌、洞室条件影响外，基线长度也是致关重要的。密闭山洞、减少背景噪声等对于提高观测精度有益，但提升的幅度不大，只能给观测系统提供一个稳定、可靠的观测环境。

| Abstract: | The DSQ water tiltmeter is build during the "Ninth Five-Year Plan".The results of baseline extending and cave further airproof indicate that the length of the baseline is crucial to the observation accuracy besides the geological condition of the station,the topography of the observation site and the cave condition.Cave airproofing and background noise reducing can improve the observation accuracy to some extent and provide the observation system a stable and reliable condition. |
