由此导致的最可怕的后果在未来才会显现出来，然而，美国的医保体制消耗着1/6的GDP，但收效甚微，在教育方面，也是一样的徒劳无功。
The direst consequences of all this lie in the future, however. America’s health-care system consumes a sixth of GDP but produces only mediocre results.
至今几乎所有的电力变换器为在线换向式的当有功功率较小，而消耗的无功较大时，对所联接母线的电压是非常有害的。
Almost all the power converters in use up to now are line-commutated, when the level of active power is low, and reactive power consumed is high, being very harmful for the connection bus voltage.
高压输电线路在输送负荷功率的同时自身也消耗有功功率、吸收或输出无功功率，线路无功会对功率因数产生很大影响。
While transmitting the load power, the high-voltage transmission line consumes the active power of its own, and absorbs or outputs the reactive power, which affects the power factor significantly.
