On this basis, the simplified tri linear analytical method to determine bi directional shearing capacity is presented afterwards and the error of this method is given.
同时本文作者提出了双向受剪承载力的三折线简化计算方法，对简化计算方法的误差进行了分析。

It was also shown that activity of tri metal catalyst was higher than that of bi metal one, and selectivity of Cu ni Cr catalyst was higher than that of nickel catalyst.
结果表明，三元金属催化剂的活性高于二元金属催化剂，选择性高于单元金属催化剂。
