When primary electrons hit the surface of the chunnel, secondary electrons are generated, which make the electron distribution at the exit hole of the chunnel more uniform
當初始電子碰撞絕緣壁時,會產生二次電子,而二次電子能改善電子在通道出口處的電子能量分佈的均勻性。Based on the theoretical analysis and experimental researches, it is presented that the wider spectra are resulted from the many fluorophores with large numbers of vibrational energy levels on the ground level in the blood cells, and the reduction of the spectral intensity is due to the reabsorption of the blood cells and the energy transfer of the collisions between the fluorophore and another one or other macromolecule. on the other hand, when the concentration of the blood cells is increased, the reabsorption of the blood cells, the secondary fluorescence due to the reabsorption and the influence of the concentration on the energy levels of fluorophores are all the factors of the red - shifted spectral peaks
在進行理論分析和研究的基礎上,提出了因血細胞中存在多種熒光團,且這些熒光團的電子能級上又存在大量的不同的振動能級,從而導致被激發的熒光團發出較寬的熒光光譜;血細胞濃度的增大,熒光團以及其他大分子之間的距離變小,造成它們之間因碰撞的能量轉移概率加大,因而易產生熒光猝滅,結果導致熒光強度的變小;血細胞溶液中重吸收所導致的熒光猝滅和二次熒光發射,以及血細胞濃度的變化對其中熒光團能級系統的影響都是導致熒光峰值波長「紅移」的原因;進而研究了led光誘導血細胞產生熒光光譜的機理。Secondly, the beam orbit offset effects caused by the initial beam offset and the linac components " offsets have been quantitatively studied first. as an example with the injector linac for beijing electron positron collider upgrading project ( bepcii ), the beam orbit offset caused by the above error effects have been simulated and analyzed
