optical brightener meaning in English
光学增白剂
光学增亮剂
荧光增白剂
Examples
- It has been demonstrated that optical brightener ( or fluorescent brightener ) can enhance viral activity , provide uv protection for nucleopolyhedrovirus ( npv ) and increase host susceptibility
光增白剂对杆状病毒具有增效和保护作用，能提高虫体对杆状病毒敏感性，这对于扩大杆状病毒杀虫剂的应用具有重要的意义。 - The foci located the basal in midgut not in control but also in test , the results showed that the addition of optical brighteners did n ' t change the spots of infection but improved the viral enhancement , in addition , infection of hemolymph cell showed that optical brightener increased sensitivity of larvae to virus , forming more foci
可见，对于处于不同时龄的供试幼虫接种病毒时，添加荧光增白剂均可提高病毒在中肠组织中的感染能力。从病毒在中肠中形成的病灶部位可以看出，实验组与对照组的病灶均靠近中肠的基底膜，荧光增白剂的加入并不能改变病毒在中肠组织的感染部位。 - The mechanism enhancement of the optical brightener is not known . shapiro et al . postulated that selected brightener including m2r inhibit or alter the chitinous peritrophic membrane ( pm ) , creating gaps in the membrane or gut lining and perhaps allowing more virions to pass from the gut lumen into the hemocoel
光增白剂对杆状病毒的增效作用的机理存在两种推测一种观点认为光增白剂是通过破坏围食膜结构的完整性，促使更多的病毒粒子穿越围食膜而发动感染的；另一种意见认为光增白剂能延迟中肠上皮细胞的脱落，促进病毒的复制繁殖。
