22381.全球水电站建设市场报告（2014-2018年）
[电力、热力、燃气及水生产和供应业,电气机械和器材制造业] [2014-10-22]
Hydropower is one of the most efficient sources of renewable energy. It is mainly derived from the energy of water moving from a high to low elevation. The kinetic energy of the flowing water helps in generating electricity. Dams and reservoirs are constructed for storing water, which is then released to run the turbine, thus activating the generator to produce electricity. In 2013, 3782.03 TWh of power was generated by hydropower plants globally. The total installed capacity of hydropower plants in 2013 was 1,160 GW and is estimated to reach 1,435 GW by 2018.

22382.全球LED通用照明市场报告（2014-2018年）
[电气机械和器材制造业,电力、热力、燃气及水生产和供应业] [2014-10-22]
An LED is a semiconductor light source used for purposes such as general lighting, backlighting, and automotive lighting. LED lighting serves several application segments, such as Residential, Office, Retail, Hospitality, Industrial, Outdoor, and Architectural. It is highly efficient and moderately priced, which can address key issues such as energy crises, resource scarcity, and climate change. Thus, the use of LED lighting enhances safety in cities and productivity in offices. Lighting consumes approximately 20 percent of all the power in the world, and by using LED lighting, people can save, on average, up to 40 percent of energy every year.

22384.全球配电变压器市场报告（2014-2018年）
[电力、热力、燃气及水生产和供应业,电气机械和器材制造业] [2014-10-18]
A distribution transformer is used in the electric distribution system to step-down the high voltage to a lower level so the end-users such as industrial, commercial, as well as household, can consume distribution conveniently. Since 2007, the DOE has regulated the energy efficiency level of low-voltage dry-type distribution transformers. The regulations were also imposed by the same on liquid-immersed and medium-voltage dry-type distribution transformers from 2010. Sometimes, a distribution transformer is designed and constructed in a way that it is mounted on a utility pole during installation and is well-known as a pole-mount transformer. The other ones, which are installed on a concrete base, at the ground level are better known as pad-mount transformers.

22385.全球印刷电池市场报告（2014-2018年）
[电力、热力、燃气及水生产和供应业,电气机械和器材制造业] [2014-10-16]
A printed battery is a thin and flexible battery composed of zinc (anode) and manganese dioxide (cathode) and is printed on a recyclable plastic. The output voltage from the battery is 1.5V with a peak drain current of 1mA. Printed batteries are used mainly for short-lifetime and low-power-source applications. As these batteries are produced using eco-friendly materials, they can be easily disposed of with household waste. The most important feature of a printed battery is that it is inexpensive. Printed batteries are used in a variety of devices such as passive RFID tags, temperature sensors, cosmetics and pharmaceuticals, interactive packaging, and smart cards.

22386.全球液压缸市场报告（2014-2018年）
[电气机械和器材制造业,其他制造业,专用设备制造业] [2014-10-16]
A hydraulic cylinder is a mechanical actuator that produces linear motion and unidirectional force by using pressurized hydraulic fluid. It converts the energy stored in the hydraulic fluid into a force, allowing linear motion of the cylinder. A hydraulic cylinder consists of a cylinder barrel, cylinder cap, piston rod, piston, cylinder base, rod gland, cushions, seal, and cylinder base connection. Hydraulic cylinders are classified into two types according to their function: singleacting cylinders and double-acting cylinders. In single-acting cylinders, fluid is pressurized from one side of the cylinder during extraction and expansion, while in double-acting cylinders fluid is pressurized from both sides. Double-acting cylinders are further divided into two types: single rod end cylinders and double rod end cylinders. Plunger cylinders, telescoping cylinders, cable cylinders, and diaphragm cylinders are some of the hydraulic cylinders available in the Global Hydraulic Cylinders market.

22387.工具行业2014年中期发展形势分析
[电气机械和器材制造业] [2014-10-16]
我国工具市场规模2011年达到了400亿元人民币的高点，随后由于经济过热、通胀高企，国家实施宏观调控，经济增长率一路下行，工具市场的规模也出现了连续两年的收缩。到2013年末，降至330亿元人民币，和2011年的高点相比，降幅达到17.5%。但是，这两年我国工具市场的变化，也不是平铺直叙一路下行。2012年是最困难的一年。刚开始，国内外工具企业面对宏观经济形势的突然变化，有点措手不及，2012年在国内工具市场上，进口和国产刀具的销售业绩双双大幅度跳水，平均下降达到15%。现在回过头来分析，我国制造业的调整幅度并没有如此之大，以致需要大幅度的减少工具消费。实际上是最终用户和中间商对宏观经济形势的变化诸多不确定性心中没底，人为地减少了进货和库存所致。

22388.全球太阳能光伏逆变器市场报告（2014-2018年）
[电气机械和器材制造业,电力、热力、燃气及水生产和供应业] [2014-10-15]
A PV inverter is a device that converts the DC current from solar panels into AC current of the required frequency, which is then supplied to the electric grid. The device uses the MPPT technique to extract the maximum amount of power from an array of solar panels. Though it functions just as a simple converter, a PV inverter is the most essential part of a solar power plant.

22389.全球水电抽水蓄能电站市场报告（2014-2018年）
[电力、热力、燃气及水生产和供应业,电气机械和器材制造业] [2014-10-15]
Hydro-pumped storage is an altered use of conventional hydropower technology to store and manage energy. Hydro-pumped storage projects store electricity by circulating water between an upper and lower reservoir. The electrical energy is converted to potential energy and stored in the form of water at an upper elevation. Pumping the water uphill for temporary storage recharges the battery, and during periods of high electricity demand the stored water is released back through the turbines and converted back to electricity as in the case of a conventional hydropower station. Hydro-pumped storage cycle efficiencies exceed 80 percent, unlike other energy storage and thermal technologies that have lower efficiency.
