将这段英文翻译为中文，保留专业术语，强调出关键点，语言简练有力：

**According to the theoretical model of system structural failure, when a serious failure occurs in a certain subsystem of a multi-subsystem system, the failure will propagate to other subsystems and even lead to global failure of the whole system, unless timely and effective intervention measures are taken. This propagation process often exhibits a nonlinear behavioral pattern.**

根据系统结构故障理论模型，多子系统系统中某一子系统发生严重故障时，故障将传播至其他子系统，甚至导致整个系统的全局故障，除非采取及时有效的干预措施。这种传播过程通常呈现非线性行为模式。
