8月，电力设备制造业加速复苏：除工业锅炉和燃气轮机外，其它电力设备重点产品产量均实现增长，尤其发电设备产量增速已连续提高3个月；海外需求稳步增长，行业出口额增速继续提高；在下游需求增长拉动下，主要产品价格上升态势明显，推动行业盈利能力保持在较高水平；企业投资意愿和投资能力较强，行业固定资产投资完成额增速也位于较高水平。

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。

Centrifugation is based on the principle of sedimentation accomplished by rapid rotation to separate liquid-liquid and solid-liquid mixtures. This separation is completed through the use of centrifugal force. Laboratory centrifuges are generally used in the separation of cells, viruses, proteins, subcellular organelles, and nucleic acids, in research and other areas. The most commonly used laboratory centrifuges are benchtop centrifuges, floor-standing centrifuges, microcentrifuges, specialty centrifuges, and ultracentrifuges. Researchers require centrifuge for various applications such as specimen preparation, new molecule development in drug discovery, and foreign particles analysis.

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.

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.

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.
