摘要
以荷叶(folium nelumbin)为实验材料,用BPCL型微弱发光测量仪测定了不同质量分数NaCl溶液处理对叶片延迟发光的影响。结果表明:低质量分数处理时,随着处理时间的增加,延迟发光的最大强度和衰减参数先增加后减小;高质量分数处理时,延迟发光的最大强度和衰减系数一直呈下降趋势;同一时间处理,随着质量分数的增加,延迟发光的最大强度和衰减参数呈动态变化,分别在处理72h的1%和96h的0.1%质量分数处达到最大强度和最大的衰减参数。
The influence of different mass fraction NaCl treatment on delayed luminescence（DL） from Lotus leaves（folium nelumbin） was investigated by BPCL.The results indicate that the lower mass fraction treatments make the initial strength and attenuation parameters of DL first increasing and then decreasing with time,and higher mass fraction treatments make the initial strength and attenuation parameters of DL basically decrease.When treat ment time is the same,the initial strength and attenuation parameters of DL differently vary with increasing mass fraction.When the time is 72 h and increasing mass fraction is 1% or the time is 96 h and the increasing is 0.1%,the initial strength and attenuation parameters of DL are the biggest.
