Nitrate esters-based propellant (NEBP) belongs to the main classes of energetic materials being used in civilian and military applications. These NEBPs are not highly stable, and during aging, some of their functional characteristics may change, what can lead to serious safety problems. A thorough analytical characterization of NEBP is of fundamental importance to provide an adequate support for their stability and safe life assessment. Moreover, in order to safely store and fully exploit these energetic materials, accurate analytical techniques and strategies are indispensable to efficiently judge their properties during aging. Although various methodologies have been developed worldwide to evaluate the aging behavior of NEBP, the characterization is not a simple task and often involves the combination of several techniques, whose results have to be evaluated together. This review sought to evaluate existing analytical techniques which can be utilized for a suitable analysis of NEBP stability and aging, evidencing their respective advantages and shortcomings. The employment of each examined technique is described and discussed by relevant examples from the literature.

硝酸酯基推进剂稳定性评估的分析方法。

硝酸酯基推进剂（NEBP）属于民用和军事应用中使用的高能材料的主要类别。这些NEBP不稳定，并且在老化期间，其某些功能特性可能会发生变化，这可能导致严重的安全问题。对NEBP进行全面的分析表征对于为其稳定性和安全寿命评估提供足够的支持至关重要。而且，为了安全地存储和充分利用这些高能材料，准确的分析技术和策略对于在老化过程中有效地判断其性能必不可少。尽管全球范围内已经开发出各种方法来评估NEBP的老化行为，但是表征并不是一项简单的任务，通常涉及多种技术的结合，其结果必须一起评估。这篇综述试图评估可用于NEBP稳定性和老化的适当分析的现有分析技术，以证明它们各自的优点和缺点。文献中的相关示例对每种检查技术的使用进行了描述和讨论。
