论文讲述了作者参与的四分量钻孔应力仪的诞生和发展,向读者展示了它的研制到逐步成功的曲折历程,体现了四分量钻孔应力-应变观测给地壳形变观测在数据处理与思想方法带来的有意义的变化。在论文最后,结合21世纪初得到的四分量应变观测的震前异常资料,体会到勇于思考、勇于创新的科学理念,对于建设我国地形变观测体系,做出自己的特色,具有重要的现实意义。
This paper describes the birth and development of the four-component borehole stress-strain gauge that the author participated in, shows the reader the twists and turns in its development to gradual success, and illustrates the meaningful changes brought by the four-component borehole stress-strain observation to the crustal deformation observation in data processing methods and thinking. At the end of the paper, combined with the pre-earthquake anomaly data of the four-component strain observations obtained in the early 21st century, I realize the scientific concept of courage to think and innovation has practical significance for the construction of China's crustal deformation observation system with its own characteristics.
