探讨了BH-4与Cu2 +的反应历程，认为该反应是分三步进行的：第一步是铜的还原反应；第二步是生成的H+分别与BH-4和OH-的反应，这是一对竞争反应；第三步是硼的水解反应。

We report a sponge spicule assemblage from the Lower Cambrian black shales of the Hetang Formation at Xiuning in Anhui Province, South China. Based on morphological differences, the spicules can be divided into 4 types including monaxons, biaxons, triaxons and tetraxons.
