Question

efficiency n.效率；功率 (1) 我们必须尽快地提高工作效率。(2) 他们的工作效率很高。(3) 这两家公司已合并以提高效率。(4) 该喷气机的喷射功率非常大。(5) 于是多种不同功率放大器的线性化技术被采用来改善无线发射机的线性度及效率。 Nowadays, efficiency often refers to energy efficiency, the effort to get more energy from existing resources: making cars that can go farther with less fuel, or appliances that do the same work with less electricity. But this noun isn't restricted to an environmental context. Efficiency can also simply be a measurement of what goes into a thing versus what comes out of it. A process with high efficiency requires only a little work to produce big results.
