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.

[电力、热力、燃气及水生产和供应业,石油加工、炼焦和核燃料加工业] [2014-10-18]
A nuclear power reactor converts heat produced by a nuclear fission reaction into electricity, using uranium as a fuel. The heat generated inside the nuclear reactor from the nuclear fission reactor is used to convert water into steam, which drives the turbo generator and produceselectricity. As there is no combustion of any material, there are no emissions of any gases such as carbon monoxide or carbon dioxide, which are harmful to the environment.

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.

14624.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.

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.

14626.合理开发利用我国页岩气资源的途径分析
[电力、热力、燃气及水生产和供应业] [2014-10-15]
由于页岩气储层具有低孔、低渗透率的物理特征(空隙1%-5%，常规天然气相应为10%-20%)，游离气量少，只有极少数天然裂缝特别发育的页岩气井可以直接投入生产，大部分页岩气井则需要经过水力压裂改造后才能获得理想的产量。

[电力、热力、燃气及水生产和供应业] [2014-10-15]
天然气水合物是由天然气分子和水分子在低温高压的条件下形成的非化学计量固体笼形结晶化合物。纯净的天然气水合物色白且可燃，很像致密的冰雪，故俗称可燃冰。其结构是由水分子构成点阵结构，气体分子则填充于结构的笼状空穴中。现已发现的气体水合物结构有3种，分别为I型、Ⅱ型和H型，天然气水合物和CO2水合物同属I型水合物。

[电力、热力、燃气及水生产和供应业,信息传输、软件和信息技术服务业] [2014-10-13]
An SCR system injects ammonia into the boiler flue gas and passes it through a catalyst bed, where the ammonia and NOx gas react to form nitrogen and water vapor. In this process, the NOx reduction takes place as the flue gas passes through a catalyst chamber. SCR is a postcombustion technology that is used in coal-burning applications to reduce the harmful NOx emissions being released into the atmosphere.
