Oxygen sensor, also known as a lambda sensor, is an electronic device used to gauge the amount of unburned oxygen left in the exhaust after combustion. It is mainly used in engines having fuel injection systems.The global motorcycle oxygen sensor market is segmented on the basis of application into entry-, mid- and full-size segments and into APAC, Europe, and the Americas on the basis of geography.

An instrument cluster is a panel that is placed in front of the rider in an automobile.It houses the controls and instruments that operate the automobile. The instruments include a fuel gauge, engine temperature gauge, speedometer, tachometer, fuel economy gauge, odometer, infotainment systems, and engine malfunction indicator.The motorcycle instrument cluster market can be segmented by technology into analog, hybrid, and digital clusters. An analog cluster is an electro-mechanic cluster that contains a physical dial and a needle for conventional instruments such as the

speedometer and tachometer. A digital cluster displays these instruments on a TFTLCD,LCD, or vacuum fluorescent display screens. Such clusters allow the possibility of reconfiguration based on driving conditions and the driver's preferences. Hybrid clusters are a combination of digital and hybrid clusters.

Motorcycle immobilizers: An immobilizer is an electronic security device that is used to prevent theft of otorcycles.

Based on application, the motorcycle immobilizer market has been categorized into cruiser bikes, sports bikes, and commuter bikes.In the sports bike segment, we have only taken touring and classic models of motorcycles for market sizing.

Clutch is an automobile device, which is designed to connect the transmission of the vehicle to the engine. It is used in every vehicle where the transmission is manual or semi-automatic. Clutches are used only in internal combustion engine motorcycles.The market encompasses the motorcycle clutches used in manual transmission vehicles and semi-automatic transmission vehicles. All motorcycle clutches that are of wet-type are considered in this report. As the transmission control used in the automatic transmission motorcycle does not have any traditional clutch components,it is considered as torque converters and not motorcycle clutches.

Marine power systems include both marine propulsion engines and marine auxiliary engines.The first kind of mechanical marine propulsion engines were steam engines, which came into inception during the 19th century. From the 20th century onward, steam engines have been increasingly replaced by two-stroke and four-stroke diesel engines and gas turbine engines. The use of liquefied natural gas (LNG) as a fuel in marine propulsion engines is gaining popularity because of the low-emission advantages that they offer over diesel.The global marine propulsion engine market is dependent on the performance of the global shipbuilding industry, as marine propulsion engines are essential for waterborne transport such as boats, cruises, merchant and passenger ships, tankers, floating,production, storage, and offloading (FPSO) vessels, and bulk carriers to move on water. Therefore, a greater demand to build new ships would lead to a higher demand for marine propulsion engines. Many countries lack the essential natural resources to produce various consumer goods due to which these nations depend heavily on a reliable shipping industry to carry out a trade on a global scale. There has been an increasing demand to increase the capacity of the diesel marine engines installed in large cargo ships.

Low-cost satellites are small satellites that are used for various applications and are placed in the low Earth orbit (LEO). They have similar characteristics to the larger satellites.The report covers the market for low-cost satellites used by the government and commercial organizations. The report segments the market by type and geography.The report also highlights the various factors contributing to the growth of the market, upcoming trends, and key challenges. In addition, it provides a detailed overview of the top vendors in the market.

国产航母从 0 到 1 稳步推进，海军现代化建设跨步向前。1）2017 年 8月 31 日，国防部发言人透露首艘国产航母将全面开展系泊试验。从 2012年引进改造的辽宁舰服役起，仅用不到 5 年时间，我国已具备自主研制航母的能力；2）国产航母实现从 0 到 1 的突破，具有里程碑意义，虽然外观与辽宁舰相似，但内部结构和舰载设备大幅提升；3）航母作为海军系统建设的核心，将带动整个海军装备现代化升级，随着未来国产航母服役，投资将由概念向产业转变。本文全面回顾世界航母发展史，展望我国航母发展蓝图，深度剖析航母产业链，寻找未来投资大机会：

2017 年 9 月 14 日，第四届中国天津国际直升机博览会开幕。本次展会吸引了来自全球 22 个国家和地区的 403 家厂商参展，共有 98 架参展飞机进行动态或静态展示。武直-10、武直 -19 等多款陆军主力机型纷纷亮相，中俄合作研制的重型直升机模型、10 吨级通用型直升机发动机也在本次航展上展出。 

古希腊哲学家赫拉克利特有一句名言"人不能两次踏进同一条河流"，但我们希望能够“预见河流的趋势和方向”。回顾机械行业的历史并思考其背后的逻辑，让我们感悟到“预判主线比什么都重要”的深刻道理。“公司分析员型”方法得出的结果往往是“管中窥豹”，而且难以引起市场共鸣、难以成为主线。只有预判到潜在的主线，才可能预见“河流”（即股价）的趋势。

2007 年至今，“和谐号”驰骋的十年代表了中国铁路跨越式发展的十年。 2017 年 6 月 26 日中国标准动车组“复兴号”率先在京沪高铁两端双向首发。9 月 21 日起全国铁路调整新运行图，“复兴号”标动在京沪高铁率先实现 350 公里时速运营，中国高铁产业再次迈上新台阶。中国铁路动车组由最初引进的 1、2、3、5 系列发展到 380A/B/C/D 系列，再发展到今天的中国标准动车组 CR400AF/BF 系列，中国用 10 年时间基本走完了其他国家 50 年的高铁发展之路。
