The energy efficiency of a water heater is measured in energyFactor or (ef). The larger the number of ef, the more efficient the water heater is.
热水器能效由能量因数或(EF)来测定,EF值越大,热水器的能效就越高。

The results show that the longitudinal wave velocity is closely correlated to strain energyfactor and exhibits the blastability of frozen soil.
结果表明,纵波速度与变形能系数关联度最大,纵波速度能较好地反映冻土的爆破性。
