为解决机场在进行智慧化程度评价过程中由于建设内容体量庞大,业务错综复杂,无法做到业务流科学划分并有效评价的难题,本文从面向任务对象角度以及面向功能属性的角度建立了基于对象-属性双维度的机场核心业务流评价体系,并提出了90项基础指标。在此基础上,通过优劣解距法对禄口机场的双维度指标层进行了分值计算。研究结果表明:双维度评价指标体系的建立有助于厘清机场业务流种类多元且流向繁杂的问题,方便后续机场进行智慧化程度评价;从基于任务对象维度的指标层分值可以看出,旅客流的隔离区外智慧化建设程度最高为73.76分。以功能属性维度划分的各指标中,感知类的数量/重量指标评分最高为79.68分,高出平均值21.4%;预测类的时间类指标评分最高为80.26分,高出平均值9.1%;决策类的事件类指标评分最高为76.30分,高出平均值10.2%。预测类和决策类的相关指标智慧化建设程度相对均衡,而感知类指标最低分为54.36分,最高分为79.68分,各业务智慧化建设程度相差较大。

为了解决机场在进行智能化程度评价过程中基础业务流指标无法定量表达的问题,通过对比分析现有评价体系方法,采用面向过程的方法对智慧机场体系框架进行构建,搭建了基于逻辑-物理框架的智慧机场评价体系;在此基础上,对框架内的各个基础指标按定性指标和定量指标2个不同的类别进行了数学上的定义与定量描述。研究结果表明:面向过程的评价体系同样也适用于机场的智能化评价体系构建,且能够从逻辑框架到物理框架对智慧机场的各个业务流和子系统进行全面的反映。对基础指标根据其数学描述采用不同的分类量化有助于对机场的智慧化程度刻画更加精确和全面。对A机场基础指标的量化发现飞行区管理基础指标中百分比型指标占20%,数值型指标占34.3%,是否型指标占45.7%,陆侧交通管理基础指标中百分比型指标占13.3%,数值型指标占13.3%,是否型指标占73.4%,且各个指标能够展现具体的量化分值,说明提出的量化方法能够适用于机场全部业务流的量化处理。

Tourmaline is a common borosilicate mineral in granite and pegmatite， and it is also an important carrier to record the physicochemical evolution information of magmas. However， the genetic relationship between pegmatite-type rare metal mineralization potential and tourmaline-bearing pegmatites is not clear， and the tourmaline geochemical indication of the mineralization type of rare metals needs to be supplemented. In the middle Altun region， extensive tourmaline-bearing pegmatite dykes are prevalent within and surrounding the Tugeman complex. In this paper， the petrology and geochemical characteristics of tourmaline within the pegmatite of the Tugeman Be-Li deposit have been comprehensively analyzed. The research delves into the genetic evolution and metallogenic potential of the pegmatite， emphasizing the indicative role of tourmaline geochemistry in discerning mineralization types in the Tugeman Be-Li deposit. major and trace element analysis of tourmaline reveals varying contents of FeO （9.37 wt.%–17.10 wt.%）， Al2O3（28.64 wt.%–35.22% wt.%）， and MgO （0.13 wt.%–2.47 wt.%） in the Tugeman Be–Li pegmatite. Li， Zn， and Sn contents range from 204 ppm to 1 590 ppm， 1 143 ppm to 4 089 ppm， and 74 ppm to 396 ppm， respectively. The tourmaline analyzed in this study is magmatic origin and belongs to schorl series， exhibits substitution relationships， including (Na， Fe2+)(X□， Al)-1， (Fe2+， Fe3+)（Mg， Al）-1， (Al，X□)(R2+， Na)-1，（Na， Mg）(X□， Al)-1andX□NaR2+-1. The trace element data of tourmaline show that lithium has four enrichment stages in different mineral crystallization phases. Notably， the tendency of tourmaline in the Tugeman Be-Li pegmatite to evolve towards elbaite implies a magmatic evolution sequence from low to high， transitioning through microcline-albite pegmatite， muscovite-microcline-albite pegmatite， albite pegmatite， and microcline pegmatite. Furthermore， we also propose that the Sc content in schorl can serve as an indicator of pegmatite mineralization typ
