Solar energy - reference solar spectral irradiance at the ground at different receiving conditions - part 1 : direct normal and hemispherical solar irradiance for air mass 1 . 5 太陽能在地面不同接收條件下的太陽光譜輻照度標(biāo)準(zhǔn)第1部分:大氣質(zhì)量1 . 5的法向直接日射輻照度和半球向日射輻照度
However , for the seismic data from the low snr region with complex surface , because of the complicated surface and underground geology conditions and the poor transmitting / receiving conditions , there exist severe static correction problem and strong disturbance in the original records so that the effective reflected waves can not be identified in the records , the snr in the original records is low and the static correction problem is severe 復(fù)雜地表低信噪比地區(qū)地震資料,由于地表及地下地質(zhì)條件復(fù)雜,激發(fā)及接收條件差,在原始采集記錄上存在著嚴(yán)重的靜校正問題及各類強(qiáng)干擾,記錄上幾乎看不到有效反射波的影子,原始資料信噪比低,靜校正問題突出。
Based on the simple describle of the basic principle of anti - disturbance high - resolution shallow seismic exploration , all the sources , the properties of digital seismic instruments , the receive method and conditions , the observation system , and the data processing and interpretation of the urban active fault detecting are discussed emphasizedly 在簡述抗干擾高分辨率淺層地震勘探基本原理的基礎(chǔ)上,重點論述了城市活斷層的抗干擾高分辨率淺層地震勘探的震源激發(fā)、數(shù)字地震儀性能、接收方式與接收條件、觀測系統(tǒng)以及數(shù)據(jù)處理與資料解釋等。
