The research on the nano-multilayer films has attracted wide attention because of their anormal properties in physics and mechanics. 纳米多层膜因常出现物理或力学性能的异常而成为薄膜研究的热点之一。
Current composite structure components mechanics research comes to relatively mature, but the joints research is relatively juvenility. 目前对组合结构构件的力学性能研究已经比较成熟，但是，节点的研究相对滞后。
