查询词典 prospecting

This paper describes the structure of the DC transmission circuit, characteristics of circuit magnetic fields and their effects on the ore-prospecting magnetic survey.

本文阐述了直流输电线路的结构、线路磁场特征及对以地质找矿为目的的磁测工作的影响。

The main factor that affects the resolution of seismic prospecting is Earth's absorption and attenuation effect on high frequency signals. Study and calculation of Earth's absorption and attenuation effect show that medium deep and deep reflectors over 135 Hz can not be recorded even by 24-bit seismometers.

地震勘探分辨率不高的主要原因是地层对地震波高频成分的吸收衰减，通过对地层吸收衰减深入的理论计算可知，既便使用 2 4位遥测地震仪，在中深层勘探中也无法记录主频超过 13 5Hz的地震波。

Mathematical models for timelapse seismic inversion are designed, which depend on the prospecting time. On the basis of this kind of models, the globally convergent continuous and recursive algorithms are constructed.

针对时间推移地震反演问题建立了依赖勘探时间的数学模型，并在此基础上设计了全局收敛的连续型及逐次递归算法。

Using the preferred VLF anomalies and its corresponding mineralizing rules, we obtained better potential targets and prospecting results, and effectively achieved the purpose of forecasting occurrence position of mineral masses in the region, and supplied evidences for further detailed geological exploration and deep prospection in the region.

该方法的运用，结合矿区矿体赋存规律，在该区取得了良好的勘查和探矿效果，有效地达到了预测矿体空间赋存部位的目的，为该区的进一步的详查和深部找矿提供了依据。

Foods high in this vitamin include oily fish such as salmon, tuna and, and fish liver oils.

维生素D含量高的食物包括诸如大麻哈鱼、金枪鱼和鲭鱼之类的油鱼以及鱼肝油。
