摘要：
We investigate the light element synthesis, such as Li, Be and B, in inhomogeneous Big-Bang Nucleosynthesis (IBBN) model. We assume the existence of a high-density island at the early universe. In IBBN model, B-11 is synthesized in the high density region with eta = 10(-8) - 10(-6) Li-7 can be synthesiszed in the high- and low density regions. As the result, Li-7 becomes higher than that of the standard BBN. In present analysis, we discuss the possibility of B production at the BBN epoch.
