The prestack migration into space should be based on accurate isochrones through the heterogeneous velocity model and the wave incidence angles. 空间叠前偏移是基于精确的通过不均匀速度模型的等时线和波的入射角。
On the basis of the measured incident angle modified coefficient of the collector panels, the relation between the daily and instantaneous efficiency is given. 在测试了该集热器阵列的入射角修正系数的基础上给出了全日效率与瞬时效率的关系。
