政策和资金等因素共同支持下，我国城轨运营历程从 2011 年的 1713 公里提升到 2016 年的 3740.6 公里（不含市域快轨），年复合增速达 16.9%，增长显著。而我国人口密度较大，地方经济发展仍不均衡，符合修建城轨标准的城市新建线路以及已有城轨城市的线路增加，将持续推进城轨发展进入快车道。

上半年，整机表现最优异的中航飞机营收增长 13.99%，配套类航发动力、中航电子、中航机电增速较高。军品具有下半年交付为主的特点，半年报不能完全反应全年情况，但行业增长已经初露端倪，正处于技术成熟拐点和财务拐点的过渡阶段。

针对航空发动机零件传统二维机加工艺设计中工艺信息管理困难和更改繁琐等问题，通过分析零件机械加工过程中工艺信息的特性，将机加工艺信息分为静态工艺信息和动态工艺信息两大类，提出并构建了航空发动机零件三维模式下机加工艺信息管理系统，阐述了机加工艺信息管理系统的体系架构和工作流程，研究实现了工艺资源库的创建和检索、基于XML的工艺信息集成和工艺规程可视化文件生成等关键技术，有效地提高了航空发动机零件机加工艺规程生成的效率和质量，缩短了航空发动机零件的研制周期。

Packaged refrigeration systems are gaining momentum as they provide substantial cost, space, and time advantages. Packaged refrigeration systems of all individual systems in-factory as opposed to filed fitted systems, which are completed on-site, require only electrical and piping services. As the fabrication of these systems can be completed before hand, they can be instrumental in reducing the overall delivery timeline. Packaged refrigeration systems are manufactured in a controlled environment, which helps to ensure higher standards of quality control. The ease of customizing these systems in relation to the required application is a major factor that will drive the demand. This reduces designing and adaption cost of single elements, as well as installation time and cost on-site. Also, these systems can be manufactured in almost all sizes, requiring minimal on-site connections. Also, the flexibility in the use of refrigerants and compressors will also encourage their adoption. Services such as commissioning are available from one source.

An offshore supply vessel is a sea motor vessel used for transporting cargos, goods, supplies, crews, and offshore exploration and production (E&P) across oil platforms. OSVs support marine offshore drilling activities through transportation of offshore energy resources, and they also facilitate the installation process of oil rigs. They are mostly used by oil and gas companies for E&P activities. The OSVs are operated by ship owners or by companies that take OSVs on lease. In addition, the OSVs facilitate maritime logistics operations for different industries such as subsea and deepwater mining.

The global motorcycle industry is two faced, where one segment is of highperformance motorcycles (considered as a luxury) and the other segment consist of two-wheelers used for commuting. Both these segments operate under contrast market dynamics with different customer behavior and value chain. The premium segment is witnessing a steady growth owing to growing culture of touring motorcycling in mature markets such as the US, Japan, and Western Europe.

Mobility scooters are electrically operated vehicles, which in recent times, are widely substituting the traditionally used mobility aids for older consumers and people with disabilities or medical conditions. Traditionally used mobility aids include manual and powered wheelchairs, rehab chairs, and rollators. Mobility scooters are primarily battery powered and come in 3-wheel or 4-wheel layouts. New generation mobility scooters are now also available in a 5-wheel layout. The fifth wheel in these vehicles is placed between the two front wheels and helps improve kerb handling. These scooters are designed for both indoor and outdoor use. The term mobility scooter in this report refers to those mobility scooters that are powered by electricity via battery packs.

2017 年 7 月 30 日，为庆祝建军 90 周年，习近平总书记在朱日和训练基地检阅中国人民解放军。本次阅兵集中映射出新时期下人民军队实战化、信息化、模块化、机动化四大特点。 

中船防务先后通过收购中船龙穴、黄埔文冲等公司完成了对集团在华南地区优质造船资产的整合，进一步完善了军、民用船舶产品体系，未来公司有望通过民船产品升级和军船订单放量而实现业绩可观增长。

一个世纪以来，军用无人机应用空间不断拓展升级，功能由靶机、通信中继、侦察监视、战场评估等战术支援角色向电子对抗、火力打击拓展，遂行任务的空间向中高空、超视距过渡。从未来作战样式来看，有人/无人机协同作战、蜂群作战等对无人机系统隐身化、模块化、智能化提出了更高的要求。
