中文拼音 [guōliúshuāijiǎn]
渦流衰減
英文
vortex decay-
The vortices are caused by quantum - mechanical inference scatterers and are accentuated by evanescent states
渦流出現是量子相干散射造成的，並與衰減模式的存在有重要關系。Eddy current decay method for measurement of resistivity and residual resistance ratio of pure metals
純金屬電阻率與剩餘電阻比渦流衰減測量方法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。
