The prestack migration into space should be based on accurate isochrones through the heterogeneous velocity model and the wave incidence angles. 空間疊前偏移是基于精確的通過(guò)不均勻速度模型的等時(shí)線(xiàn)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. 在測試了該集熱器陣列的入射角修正系數的基礎上給出了全日效率與瞬時(shí)效率的關(guān)系。
