1) often poor
常差
1.
Analysis of optical micrometer start with the working principles,summed up the precision measurement standards are often poor readings in the presence of further analysis of the standard-foot inverted,the existence of the two-step cost-reading problems,so as to solve the emerging standards the inverted-foot elevation difference calculation.
从分析光学测微器的工作原理入手,总结出精密水准测量的读数中有常差的存在,进而分析出当水准尺倒立时,存在读数的两步化算问题,从而解决了出现水准尺倒立时的高差计算问题。
2) normal moveout
正常时差
1.
The stack method after normal moveout is not effective.
本文针对因存在噪音和信号比较弱 ,致使正常时差 (NMO)校正迭加方法难以奏效的问题 ,提出提高信噪比和增强反射信号同相轴连续性的共反射面元 (CRS)迭加方法 。
2.
In view of the situation that normal moveout correction stack method could not work very well for the low signal to noise ratio, we give an enlarging common reflection surface stack method to raise signal to noise ratio and enhance reflect wave s continuity.
因此 ,针对因地震资料的信噪比较低而导致常规的正常时差校正叠加方法难以奏效的情况 ,提出了提高信噪比和增强反射波连续性的扩大反射面元叠加方法。
