我们队在进行多次迭加施工过程中,忽然出现一张“奇怪”的监视记录,如图2。在记录的开头部位各道工作都很正常,但在记录的中间部位辅助讯号道特别明显工作不正常,与相同物理点所采用的因素完全一样的正常记录图1作对比,从“奇怪”的监视记录上清楚地看出: 1.爆炸讯号道从1.9秒开始背景不平静,2.2秒出现没有规律的大跳; 2.公测讯号道从2.2秒突然向下抬,在抬的过程中,不平直,有抖动; 3.计时讯号道从2.2秒开始,没有100周讯号显示,基本上为一条直线,回放100周讯号正常;
Our team suddenly encountered a “weird” surveillance record during the multiple overlay construction, as shown in Figure 2. The work at the beginning of the record was normal, but it was found that the auxiliary signal track was notably working abnormally in the middle of the record, as compared to the normal record of exactly the same factor used for the same physical point. Figure 1 Contrast, from “weird” Monitoring records clearly see: 1. Explosion signal Road from 1.9 seconds to start the background is not calm, 2.2 seconds there is no regular big jump; 2. The beta signal Road suddenly lifted down from 2.2 seconds in the lift process, not Straight, jitter; 3. timing signal Road from 2.2 seconds, no 100-week signal display, basically a straight line, playback 100 weeks signal normal;
