综述了多种本质安全化设计方法和策略，并介绍了多种描述不同反应路径中有害物质潜在威胁的定量评价指数。由于化工过程的复杂性，通常存在多个稳态操作点，而这些稳态点的稳定性也不尽相同；另一方面，位于奇异点附近的操作点可能会自动引发系统的振荡现象，降低系统的稳定性，影响产品的质量。为解决这一问题，探索设计了定量表征稳定的稳态点的稳定性的方法，用于考虑稳定性的化工过程的优化设计；针对振荡现象，提出了将这类奇异点所在范围作为约束条件来考虑的流程设计方法。

Inherently safer design methods and strategies were briefly reviewed in this article, and several indexes to evaluate the potential harms of different reaction routines were introduced. Multiply steady states exist in chemical processes because of the strong nonlinearity of the processes, the stabilities of the steady states were usually different from each other, and the characteristics of the stable steady states are also different even if they are very close to each other. In addition, singularity points accompanied by oscillation phenomenon should be avoided for stable operation and consistent product quality. A quantitative stability index was proposed to describe the stability of all stable steady states, and an index to describe how close an operation point was allowed to singularity points was proposed. These indexes were useful in inherently safer process design.
