近年来，饮水与健康知识得到大力宣传和普及，人们逐步对水家电有了全新的认识，这为水家电的发展提供了机遇。目前，中国水家电家庭普及率远低于欧洲及亚洲的一些发达国家，水家电在中国市场上的发展还处于起步阶段，未来发展前景十分广阔。中怡康将水家电按产品类型划分为净水设备和饮水设备，净水设备包括直饮机、管线机和净水器；饮水设备包括传统饮水机和净水桶，本文重点分析净水设备市场变化情况。

2013年上半年，元器件板块实现营业收入1109.5亿元，同比增长21.8%；实现归属于母公司所有者净利润75.7亿元，同比增长40.8%；整个板块综合毛利率为22.0%，同比增加2.7个百分点。若剔除京东方A，则元器件板块2013年上半年营业收入同比增长16.3%；归属于母公司所有者净利润同比增长8.9%；板块整体综合毛利率同比微幅增加0.3个百分点。

《反垄断法》严格禁止经营者滥用其市场支配地位排除限制竞争，禁止供应商与经销商达成协议，以固定产品的零售价格或限定最低零售价格。汽车供应商一旦被确认存在以上违法行为，可能将受到严厉处罚。

An LED is a semiconductor light source used for various applications such as general lighting, backlighting, and automotive lighting. LED lighting applications include residential, office, retail, hospitality, industrial, outdoor, architectural and others. LEDs are gaining acceptance in these applications because of their greater efficiency and low cost. Also, LEDs are able to address some key issues that the world faces today such as the energy crisis, resource scarcity, climate change, safety in and attractiveness of cities, productivity in offices, and an enhanced sense of health and wellbeing, as lighting consumes approximately 20 percent of all electricity in the world. LED lighting can save on an average up to 40 percent of energy.

Aircraft electrical systems are used to generate, control, and distribute the electrical power throughout the aircraft. The electronic flight instrument integrated in the new generation aircraft completely rely on the electrical power system. Some of the major functions of an aircraft electrical system include controlling and operating essential aircraft systems, operating passenger services systems (such as cabin lighting and operation of in-flight entertainment systems), as well as controlling aircraft flight instrument systems. The products that come under the aircraft electrical systems are auxiliary power units, aircraft batteries, engine-driven generators, motors, power conversion, and distribution systems. Devices used to provide energy to large aircraft other than for the propulsion are known as auxiliary power units. To run the electrical systems of the aircraft, auxiliary power units generally produce 115V at 400 Hz of power. Auxiliary power units provide power through single-phase systems or three-phase systems. Aircraft batteries are the final source of backup power, but the power usage is limited due to the short life of the battery. Engine-driven generators produce power which is used to supply power to the aircraft.
