seismic recording system 中文意思是什麼
seismic recording system
解釋
地震記錄系統-
The principle of vibrator is to introduce scattered energy to underground in a comparatively long time, and collect the energy through correlation and compress it into a narrow pulse. the portable high - frequency vibrator system, developed by key lab of geo - exploration and instrumentation ( jilin univ ), ministry of education, generates chirp signal and accumulates energy through a long - time bestiring. according to the characteristics of vibrator, the seismic recorder that operates on - line with vibrator must have these functions as follow : first, it must have the ability of recording a great quantity of data. second, it must have assistant channels to sample reference signal. third, it must have the function of data correlation in real - time
可控震源利用可控的小能量、長時間激發波來實現沖擊震源瞬時產生的大能量激發波。在利用可控震源進行地震勘探時，要求地震儀長時間記錄地震信號，這對地震儀的采樣長度提出了很高的要求。受存儲量和數據傳輸速度的限制，絕大多數地震儀很難對如此大的數據量進行記錄，同時，可控震源要求地震儀有兩個輔助通道並且具有數據相關功能，目前國內還沒有出現滿足要求的地震儀產品。 -
Firstly, seismic exploring databases are the base of the management, so a detail description is provided which some databases achieved in the past ninth five - year plan must be imported and surface layer database are built newly instead of traditional mode of recording and storing the data. secondly, according to the idea of gis ( geographic information system ), some query and display techniques are discussed, for example, the technique of visualizing user interface, the technique of controlling the order of a map, and the technique of searching for the database based on a seismic line
從技術發展的角度看，盡管通過技術革新和技術改造，地震勘探野外採集採取了許多技術措施，例如，新的施工工藝，高性能的採集儀器，現場處理控制等，但目前的野外生產管理仍有沿用幾十年來傳統的管理方式的現象，採用傳統的文檔、圖紙，手工錄入這種管理方式，主觀性、隨意性較強，信息化程度低，管理水平不高，大量的時間被浪費在數據、資料的管理和查找上，由於沒有較好的技術手段，缺乏科學性。 -
Struggled through 3 years, we had made a 480 - channels marine multi - component seismic exploration system. include new circuit design of digital package, omnidirectional 3 component geophone, ocean bottom towed cable, marine four component seismic acquisition unit, hydrophone, recording system etc. in july 2001, this system was used in dagang field and worked over twenty km. we obtained a good seismic data
