Energy Star's recently updated television ratings judge TVs according to how much energy is used in full operation rather than how much it USES in standby only.
能源之星最近提高了电视评级的标准，现在的标准根据的是完全开机使用下消耗的能耗，而不是待机时的能耗，评级必要条件根据屏幕尺寸的不同而不同。
The system is designed to be similar to the energy Star ratings, which let consumers pick out an energy-efficient appliance without wading through complicated specs.
这个体系的设计和能源之星认证很类似，有了能源星级认证，消费者不需要在复杂产品规格中苦苦比较就能挑选到合适的节能设备。
Therefore, they have thermal ratings (MWth) about 3 times that of the electrical ratings and this thermal energy is the energy that must be removed, and is what is shown in the figure and table above.
在这种情况下产生的热功率大约是电功率的3倍，这些热功率就是必须被清除的，热功率显示在上面的图和表中。
To ensure the impeller head and flow ratings, shaft power should be reduced, to reduce energy consumption, and improve impeller efficiency so as to save energy.
为保证叶轮的扬程和流量，必须降低轴功率，减少能耗，提高叶轮的效率，才能达到节能减耗的效果。
