求翻译：随着反应的进行，聚合物的分子量增加，π键密度增加，π电子共轭体系增大，因为共轭效应使轨道能量下降，吸收增强，波长红移是什么意思？

As the reaction proceeded, the polymer molecular weight increased π bond density of π electron conjugated system increases, because the conjugate effect to lower the orbital energy absorption enhancement, the wavelength red shift

As for the reaction, polymer molecular weight and density should be key to increasing e-conjugate system, increased by the fact that the conjugate effects the orbit down, and energy absorption, wavelength Red to move

Along with response march, the polymer molecular weight increase, pi the key density increases, pi the electronic conjugate system increases, because the conjugate effect causes the orbital energy to drop, the absorption strengthens, wave length red shift

As the reaction progresses, polymer molecular weight increases, π key density increased, PI-electron conjugated systems increases, because the conjugate effect down orbit energy, absorption enhancement, wavelength redshifts
