为了高效筛选可用于民用飞机的先进技术，结合不同领域的技术特点，从实际案例中提取技术竞争力、技术成熟度、经济性、工程方法、技术标准5个评价维度，并建立评价指标体系，提出民机技术适用性评价方法。从技术应用角度出发，采用云模型和逆向云发生器确定指标权重，结合各行业技术标准、适航标准、民机全寿命周期建立指标评价准则，对技术案例进行综合评价。结果表明：该方法能合理对比不同行业的先进技术，区分处于不同水平的同类技术，排除对民机无增益或受到限制的技术，筛选出与民机匹配程度高的先进技术。

In order to select advanced technologies applicable to civil aircraft, technical characteristics from various fields were integrated to develop an evaluation framework. Five key evaluation dimensions were identified: technology competitiveness, technology readiness assessment, economic impact, engineering methods, and technology standards. From practical case studies, these dimensions were derived and used as the basis for an evaluation index system. A technology application perspective was adopted, utilizing a cloud model and a reverse cloud generator to determine indicator weights. This approach incorporated technical standards from different industries, airworthiness standards, and the entire life cycle of civil aircraft to create comprehensive evaluation guidelines. The results show that this approach effectively compares advanced technologies across different industries, differentiates similar technologies at various levels, and eliminates those that offer no benefit or are unsuitable for civil aircraft. This evaluation approach successfully selects advanced technologies with a high degree of compatibility with civil aircraft.
