| 摘 要： | 2004年我国“数字地震观测网络工程”决定在我国布设40套YRY-4型四分量钻孔应变仪。本文介绍5·12汶川地震前后分量应变仪观测到的应变异常及根据应变异常与其它观测手段对8·30会理6.1级地震较准确的预测。据此，提出我国有必要加速应变密集台网建设。

| Abstract: | In 2004,China's National Digital Network of Earthquake Observation planned to deploy 40 YRY-4 Four Component Strainmeter. Clear strain anomaly before 2008.5.12 was observed at YRY-4 strain stations close to Wenchuan. Another anomaly occurred before the Lihui ML 6.1 earthquake on Aug.30,2008 and a prediction of the quake made by this anomaly was successful. Thus it is very important to speed up a nation wide dense network of strain observation. |
