Average synchronization and temporal order characterized by the rate of firing are studied in a spatially extended network system with the coupling time delay, which is locally modelled by a two-dimensional Rulkov map neuron.It is shown that there exists an optimal noise level, where average synchronization and temporal order are maximum irrespective of the coupling time delay. Furthermore, it is found that temporal order is weakened when the coupling time delay appears. However, the coupling time delay has a twofold effect on average synchronization,one associated with its increase, the other with its decrease. This clearly manifests that random perturbations and time delay play a complementary role in synchronization and temporal order.

目前,沉积物中生物硅含量的测定方法面临耗时长、步骤繁琐、工作量大,及缺乏国际统一的标准样品的问题。本文采用碱式连续提取法分析了贵州喀斯特地区水库表层沉积物的生物硅含量,并采用硅铝截距法证实了Demaster斜率截距法的准确性。结果表明,01、05、1 mol/L Na_2CO_3溶液提取分析得到的生物硅含量是一致的,其中01 mol/L的Na_2CO_3更适合喀斯特地区水库沉积物生物硅的提取和含量
