<正>对竹结构材螺栓连接件的承载力和破坏形态进行了静载实验研究，结果表明：用竹结构材连接件的结构具有较高的强度、刚度，以及很好的延性。竹结构材连接件的夹板与螺栓同时达到弯曲变形破坏状态。具有较好的整体受力特征，能够保证剪力的可靠传递。

Common plug-in approach neglected sample size in quantifying DNA evidence. It leaded to inaccurate results and overweight DNA evidence. The formula of calculating likelihood ratio (LR) was obtained when Bayes model was used. Two numerical examples were separately calculated according to the Bayes method and the common plug-in approach. The results showed that the Bayesian method was more conservative and accurate than that of the plug-in approach.
