Normal method was used to purify the polysaccharide of spirulina platensis, pspi ( mw23000 ) was got. pspi had cooperativity for immobilized pc to inhibit pancreatic cancer cells
在第四章中，研究了光固定化藻藍蛋白在藻多糖的協同作用下對人胰腺癌細胞sw1990生長的抑制作用。 -
The paper concentrates on seismic wave - field forward modeling and migration for the fractured reservoir. it researches the wavefield extrapolation operator for lateral variation of velocity, design four theoretical models and seven practical models with fracture and cavity. base on the progenitor, in the frequency - wavenumber domain with the pspi wavefield extrapolation operator and arithmetic of forward modeling and migration that applied lateral variation of velocity which is strong, the paper obtains the result of numerical simulation and the wavefield characteristic by the way of the forward modeling and depth migration of poststack seismic wavefield
本文圍繞縫洞儲層地震波場正演與偏移問題，研究了適用於橫向變速波場延拓運算元，建立了四個理論的縫洞模型和七個實際的縫洞模型，在總結、分析前人的研究成果的基礎上，利用適合橫向速度劇烈變化的相移加插值的波場延拓運算元，在頻率?波數域對上述的地質模型進行正演、偏移處理，最後得到了縫洞儲層地震波場的一些特徵。 -
When the concentration of pspi was 17. 5 mg / l, the inhibition rate could be 50 %, compared with 40 % of pc group
Smgjlx可使固定化藻藍蛋白對sw1990細胞的抑制率由不加多糖的40上升為50 。 -
Firstly, the paper starts from the one - way wave equation of wavefield extrapolation, research the relationship and transform condition of wavefield extrapolation operators, and improves on the wavefield extrapolation operator and so heightens the operation efficiency, and chooses the pspi that fits to the lateral variation of velocity to resolve the wave - equation, which lay a foundation of the theoretic study
首先，從波場延拓的單程波方程出發，研究了頻率?波數域的波場延拓運算元之間的相互關系和轉換條件，並在此基礎上改進了波場延拓方案和提高了運算效率，選擇了適合於縱橫向速度劇烈變化的pspi方法求解波動方程，為整個研究打下了理論基礎。
