本文利用在微博抓取的京张地区29家滑雪场的游客评论文本,通过Snow NLP模型和TF-IDF算法分析滑雪场游客情感和认知要素,基于随机森林算法探究不同认知要素对游客情感的影响程度。研究结果表明:所有类型滑雪场的游客积极情感占比最大,中性情感占比最小,且随着滑雪场等级降低,积极情感占比呈下降趋势;场所/地域要素是滑雪场游客最主要的认知要素,而人文和建筑认知最少,其中积极、中性和消极情感游客的主要认知要素分别为活动、场所/地域和设施;不同认知要素对各类滑雪场游客情感的重要程度存在显著差异。研究结果对全面理解滑雪场游客认知与情感提供一定科学依据。,有助于优化滑雪场经营管理策略,提升游客满意度和忠诚度。

To measure the surface stress of thin laser cladding coatings with Rayleigh waves based on the cross correlation function, this pa- per introduced the influence of cross correlation step length on the stress measurement. Flat-shaped specimens made of laser cladding Fe314 alloy coatings were performed by static tensile tests, and Rayleigh wave signals were collected during the test process with an ultrasonic pulser and receiver instrument combined with two Rayleigh wave transducers. The difference in time of flight between two signals was de- termined based on the cross correlation function. The microstructure was observed by scanning electronic microscopy. The influence of the stress on the propagation velocity of Rayleigh waves and the relationship between the difference in time of flight and tensile stress under dif- ferent cross correlation step lengths were analyzed. The inhomogeneous deformation of the coatings affects the relationship between the dif- ference in time of flight and tensile stress; the stress measurement of the coatings is nearly constant with the increase of cross correlation step length when it attains one cycle.
