aeromagnetic surveying meaning in English
航空磁测
Examples
- The application of aeromagnetic surveying data to the reconnaissance of the dali - ruili railway line
瑞丽铁路初测中的应用研究 - In middle and high mountain areas , the landform is complex , the flying altitude should be relatively high , and the intensity of magnetic anomalies detected by aeromagnetic survey is hence relatively weak
摘要中高山地区的地形复杂，飞行高度较高，航磁测量获得的磁异常强度相对弱小。 - Abstract : based on 1 200000 aeromagnetic survey data performed in 1998 , and referred to materials of geolo - gic and geochemical prospecting of the working area , this paper discusses the relationship between the characte - ristics of magnetic field , magmatic rocks , fault structure and the distribution of mineral resources , and investigates the geologic metallogenic environments , and sets up the prospecting criteria for hydrothermal and volcanic - sedimentary copper , lead , zinc , gold , iron , manganese deposits , then makes the prognosis of the prospecting potential of the working area
文摘:本文以1998年1 20万航空磁测资料为基础，参考地质和化探资料，对工作区磁场特征、岩浆岩、断裂构造与矿产分布的关系进行探讨，研究地质成矿环境，建立寻找热液型和火山-沉积型的铜、铅、锌、金、铁、锰矿找矿标志，对本区找矿远景进行了预测。 - In order to utilize the magnetic anomaly information obtained by high - precision aeromagnetic survey more effectively , this paper , based on the reliable proof of the existence of weak magnetic anomalies in middle and high mountain areas and combined with characteristics of middle and high mountain areas , has advanced an improved nonlinear filtering method and described its effect in practical application
为了更有效地利用高精度航空磁法测量得到的磁异常信息，在充分论证中高山区弱磁异常存在的可靠性基础上，结合中高山地区特点，提出了改进的非线性滤波方法，并给出其实际应用效果。
