大型仪器在现代科技进步中所起的作用是毋庸置疑的。在地球科学领域中,每一个重大的发现或理论的证实,都离不开大型精密仪器的应用。板块构造学说从假设到证实,依赖于地磁测定及精密大地测量;最基 The role of large instruments in modern technological progress is beyond doubt. In the field of earth science, every major discovery or theory can not be separated from the application of large-scale precision instruments. Plate tectonics theory from assumptions to prove that relies on geomagnetic measurements and precision geodesy; the most basic
