2．4逻辑类型的通用性对比一下第1．1节介绍的GO操作码类型和第1．2节介绍的故障树逻辑类型，读者应该承认：GO法给工作者提供了非常通用的逻辑类型。从本质上讲，大部分故障树模型使用两个完全的逻辑类型（与门和或门），使用一个不完全的逻辑类型（圆形的或底故障事件）。另 Versatility of Logical Types In contrast to the GO opcode types described in Section 1.1 and the fault tree logic types introduced in Section 1.2, readers should recognize that the GO method gives workers a very general type of logic . In essence, most fault tree models use two complete logical types (AND and OR) and an incomplete logical type (round or bottom fault). another
