摘要
TEM实际工作往往遵循极限探深的理论 ,采用要探多深就用多大回线边框的做法 ,限制了TEM应用的发展。本文先通过几个实例说明小框TEM可以实现较大的勘查深度 ,然后着重从理论上论证之 ,并探讨了影响极限探深的有关问题。文章最后介绍了小框TEM工作方法技术 ,供勘查者参考。
The penetration depth of TEM commonly follows the ultimate depth theory in practice that the depth approximately equals to the length of the square loop. It has been preventing TEM from wide application. With some examples practically conducted, this paper illustrates it is possible to reach deeper with smaller square loop and verifies it theoretically. Furthermore, the influence factors of ultimate depth and the techniques of TEM with small-size square loop are discussed.
