脈沖瞬變法 的英文怎麼說
中文拼音 [màichōngshùnbiànfǎ]
脈沖瞬變法
英文
pulse transient method-
Being a method of time - domain electrical magnetic surveying, the transient electromagnetic method ( tem ) can transmit first pulse electromagnetic field to underground making use of loop or electrical source and receive secondary induction field during of the pulse intermission
瞬變電磁法是一種時間域電磁測量方法，是利用不接地回線或接地線源向地下發送一次脈沖磁場，在一次脈沖磁場的間歇期間，採用不接地線圈接收感應二次磁場。Correlative method input system
相關對比法感應脈沖瞬變系統With development of industry, there are a lot of new kinds of physcial models, of these there is one that can not be described only by impulsive differential system. in this case, we should switch to a new set of differential equations taking into consideration momentary perturbations of impulsive nature. a general description of such systems was called impulsive systems with variable structure
隨著工業的發展，出現了許多新的物理模型，其中有一類僅用脈沖微分系統無法恰當地描述，這時，就需要考慮具有瞬時脈沖攝動性質的一族新的脈沖微分方程，對這樣的系統我們一般稱為具有可變結構的脈沖微分系統。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。分享友人
