This paper analyzes on some factors influencing the water accumulation during the soil freezing process, probes into the mechanism of the water and salt migration during the process of water accumulation, and points out that the water accumulation of frozen zone provides the effect of water and salt migration for the hibernating propagation of the forest in the seasons of winter and spring
分析了土壤凍結過程中水分積聚的影響因素，探討了水分積聚過程中水鹽遷移的機理，指出凍結帶水分積聚為冬春季林木越冬繁衍提供了水分，同時鹽分也隨水分遷移到地表。 -
This paper presents the prestack time migration to curved rays for minor fault blocks, which is of more accurate migration, allowing the travel - time equation to be more close to the real pathway of layered media seismic wave propagation, the focused imaging to be more precise, the migrated results to be of good preserved amplitude processing property and the output trace gathers to be used for the lithologic analysis and inversion study
採用彎曲射線疊前時間偏移技術使小斷塊準確偏移歸位，其走時方程更接近層狀介質地震波的真實傳播路徑，成像聚焦更精確，且通過特殊振幅處理，其偏移結果有很好的保幅性，輸出的道集可以用於巖性分析和反演研究。 -
From 1920s up to now, various techniques and methods for wave field decomposition, propagation and migration / imaging have been well developed, such as the kirchhoff asymptotic method, frequency - wavenumber domain phase - shift and phase - shift - plus - interpolation methods, and the one - way wave equation based phase - screen and generalized screen methods, etc. wave field extrapolation in these methods is implemented based on the expansion of the wave field by sets of basic functions like spatial fourier harmonies, modes, and green ' s functions
自上個世紀二十年代至今，波場分解、傳播與偏移成像技術經歷了將近一個世紀的發展，形成了多種不同的方法，如kirchhoff波動方程高頻近似解方法，頻率-波數域的相移（ phase - shift ）方法和相移-內插（ pspi ）方法，以及在混合域中基於單向波動方程的相位屏、廣義屏方法等。
