矢算

In order to solve exactly the dynamic problems of the double coordinate coupling harmonic oscillators, the quantum unitary operator corresponding with classical canonical transformation is derived using the momentum eigenvector in Fock representation by constructing asymmetric integration.

为了精确求解双模坐标耦合谐振子体系的动力学问题，利用动量本征矢在Fock表象中的表示构造不对称积分，找到了与经典正则变换对应的量子么正算符。

Based on the forenamed theory, Estimated the Total Electron Content including the second-order ionospheric error. Established the 2°×2° geomagnetic vector grid-model over mostly area of China , then processed some dual-frequency data to indicate the algorithm is feasible and correct. Obtained some useful conclusion after analyzing the result of data processing.

本文计算了基于中心电离层单层模型的覆盖中国区域的2°×2°地磁场格网点的矢量值，对计算结果的X、Y、Z三个方向分量进行二次曲面拟合，对两种考虑地磁场影响计算包含电离层延迟误差二阶项的TEC估计结果进行了计算，验证了拟合模型的正确性和可行性，并对试算结果进行了分析，得到了一些有益的结论。
