  1. Facing the problem that we always ask ourselves whether the technique and parmeters we use are suitable, we have to consider it in five main processing step, deconvolution, static correction, normal moveout, noise attenuation and migration

    根據噪音在處理過程中的不同階段表現屬性不同,處理中採用不同的處理手段或不同的處理參數分階段對噪音進行衰減。以便做到最大限度壓制噪音,而盡可能不損傷有效信號,提高原始資料的信噪比。
  2. It uses the encouragement of step wave or other impulse current field source to produce the transition process field in earth. in the moment of shutting the power it produce the volute alternating electromagnetic field. from the abnormity of measuring the attenuation character of the second induction electromagnetic field, which produced by underground medium with time change, the conductive capacity and the position of the underground non - homogeneous substance can be analyzed

    瞬變電磁法( transientelectromagneticmethod )是一種時間域的電磁勘探方法,利用階躍波或其它脈沖電流場源激勵,在大地產生過渡過程場,斷電瞬間在大地中形成渦旋交變電磁場,測量這種由地下介質產生的二次感應電磁場隨時間變化的衰減特性,從測量得到的異常分析出地下不均勻體的導電性能和位置,從而達到解決地質問題的目的。
  3. 2. one voltage controlling manner is presented. this manner combines amplification and attenuation, and fine control and coarse control can be operated separately, it can adjust the amplitude by 1mv step in the range of 50mv to 10vpp conveniently

    2 .提出一種放大與衰減相結合,精細控制和粗略控制分別進行的電壓控制方式,可以方便地實現信號幅度在50mv ? 10vpp之間以1mv的步進改變。
