double difference meaning in Chinese
二重差分
Examples
- Equation derivation and simulated calculation demonstrate that double difference algorithm allows us to get the absolute locations of earthquakes with certain accuracy by using the nearby station phase arrivals
在此基础上，通过分析和模拟计算表明，应用近台资料时，双差法有可能给出一定精度的地震绝对位置。 - Based on the fundamental theory of earthquake location , it is found that the data recorded at nearby stations are applicable in double difference relocation algorithm , but not in other relative location algorithms
摘要从地震定位的基本原理出发，分析认为近台资料可用于双差定位算法，但不能用于其他相对定位方法。 - In the case that hypocenter depth is far less than the epicenter distance without depth phases available , only the relative epicenter distribution could be obtained accurately by double difference method , the depth determined would be not stable
当震源深度远小于震中距时，如果没有深度震相的参与，只能得到误差较小的震中相对分布，深度的相对位置仍有较大的误差。 - This paper fist assumes that the landslide object is a rigid , sets up a dynamic model of landslide , forms double difference observation data by using the gps carrier phase observation data on monitoring point after deformation and base point , proposes a kalman filter model of landslide monitoring
摘要首先假设边坡滑坡体为刚体，建立了边坡滑坡的动态模型，用变形后的监测点和基准点上的gps载波相位观测值组成双差观测值，提出一种滑坡监测的卡尔曼滤波模塑。
