Both range and its standard deviation are calculated according to surface energy approximation and meanenergy approximation.
用表面能量近似和平均能量近似从背散射谱上计算了射程深度和射程分布的标准偏差。

Another proposal is to subsidise the cost of installing LED lighting in place of incandescent and fluorescent lamps, which would meanenergy savings of 80% and 50% respectively.
另一种构想是，提供补贴以鼓励安装LED灯来取代白炽灯和荧光灯，这意味着各节省80%和50%的能源。
