目前经常出现某某地区的某某测段上重力变了某某微伽,一经检查,这种变化不存在了。有的数据变化虽未检查落实,但并没有发现明显的构造变动。这说明工作的质量还不是很好的,需要改进。 流动重力测量中有待改进的地方很多,我认为目前的首要问题是:1.要认清地震预报中流动重力测量的特点;2.要合理布设测点;3.要尽可能减小系统误差。其它的问题,如重力仪格值的标定等问题,虽然还没有解决得很好,但已为大家所重视了,本文不再赘述。
At present there is often a certain region of a certain measurement of gravity changed a certain micro-Jia, upon examination, this change does not exist. Although some data changes were not checked, no obvious structural changes were found. This shows that the quality of the work is not very good, need to be improved. The main problems to be improved in flow gravimetry are many, and I think the most important problems at present are as follows: 1. We should recognize the characteristics of gravity flow measurement in earthquake prediction; 2. We should lay out the measuring points reasonably; and 3. We should minimize systematic errors. Other issues, such as calibration of gravimeter values, have not been solved well, but they have been taken seriously by everyone and will not be repeated here.
