求翻译：从表3中可以看出，三种支架的理论安全系数都符合要求，其中不锈钢支架最大，其次为CoCr合金支架，而镁合金支架安全性能最小是什么意思？

As can be seen from Table 3, three stents are in line with the theoretical factor of safety requirements, including the largest stainless steel stent, followed by CoCr alloy stent, and magnesium alloy stent minimum safety performance

May see from table 3, three kind of support theory safety coefficients all conform to the requirement, in which stainless steel bracket are biggest, next is the CoCr alloy support, but the magnesium alloy support safety performance is smallest

As can be seen from table 3, three theoretical safety meet the requirements of framework, with stainless steel bracket maximum, followed by CoCr alloy bracket and safety of magnesium alloy support minimum

Can be found out from Table 3, the theoretical safety coefficient of three kinds of supports fulfils requirements, among them the stainless steel support is the largest, secondly it is CoCr alloy support, and the magnesium alloy supports the safe performance the minimum
