电能表的简称，是用来测量电能的仪表，又称电度表，火表，电能表，千瓦小时表，指测量各种电学量的仪表，分类-Short for watt-hour meter, is used to measure electric energy meter, also known as the meter, fire, watt-hour meter, kilowatt-hour table, the table refers to measure a variety of electrical instrume

轴承静态计算，利用超松弛迭代法计算固定瓦可倾瓦轴承在静态下的承载系数-Bearing static, calculated fixed-watt tilting pad bearings under static load factor in the use of ultra-relaxation method

电功率是在该电能是由一个电路传送的速率。权力的单位是瓦特，每秒1焦耳。 电力通常是由电动发电机产生的，但也可以由源如电动电池供给的。它通常是通过一个电力电网供给到企业和家庭用电力工业。电力通常是由千瓦小时（3.6兆焦耳），其功率在千瓦乘以小时运行时间的产品出售。电力公用事业使用的电表，这使运行总计交付给客户的电能量的测量功率。-Electric power is the rate at which electrical energy is transferred by an electric c
