【摘要】 本文介绍了一种全自动大地电磁测深仪。仪器的研制工作是在法国地球物理研究中心G.Clerc博士领导下进行的。仪器的主要特点是采用CMOS微机自动操作,从而使之功耗低,自动化程度高和轻便灵活。这是新近发展的一种新型物探仪器设备。 本文讨论了该系统的基本原理、测量特点、测量灵敏度和噪声情况等。同时,也简要地讨论了信号的处理和控制等问题。更多还原

【Abstract】 In this paper, the new magnetotelluric equipement which is used for forecasting the state of activation of the voleanos by measuring the slight variations of the magnetotelluric field of the earth is discussed. The devolopement of the equipement is carried out under the direction of Dr. G. Clere. The main features of the equipement are the automatic manipulation run by the CMOS microprocessor and the very high sensitivity.The fundamentals of the eqipement, the characteristics, and the sensitivity are discussed together with the treatment of the noise and the processing of the data.更多还原
