礼品系列连运费及派递费在内，取价138元至728元不等，派递点覆盖内地二千多个城市。 - Fortunately , the modern geodetic measurements such as the global positioning system ( gps ) technique can overcome the shortage of the geological and seismographic methods in the time dimension ; and yet , the coverage of the geodetic survey stations is not sufficient . as a result , it is necessary to employ numerical simulation to investigate the continuous deformation of the crust
而以全球定位系统( gps )等技术为主的大地测量方法弥补了地质和地震学方法在时间维上的不足，但大地测量方法存在测点覆盖不足及测点地理分布不均匀的缺点，因此，要得到连续的地壳形变场有必要借助数值模拟方法。 - This paper proposes a method for optimizing the parameters of geometry system . based on the ray tracing for the built - model , discussing and analyzing the parameters of geologic aim such as the bin size , calculating the fold of aim layer ' s common reflection point , comparing the fold of crp with the fold of common mid - point , the geometry system ' s parameters are adjusted to improve the low fold bins , the quality of data collection and effect of exploration
本文提出了首先建立目标地质体的数字模型，根据射线追踪正演分析，目标地质体的参数分析(面元分析等) ，统计求取复杂地质模型目标层真正的共反射点覆盖次数，比较cmp面元与实际crp面元的覆盖次数差异， cmp道集对应的共反射点面元分析，针对覆盖次数较低的目标层面元调整和优化观测参数，提高目标层的采集质量和勘探效果。
