Results show that mass area ratio (mar) is a primary factor to average daily efficiency and instantaneous efficiency curve of tubular solar water heaters is not straight line.

结果表明，水量配比(MAR)是影响日平均效率的主要因素；真空管式太阳热水器的瞬时效率不是线性分布。

The analysis includes the concentration ratio at the base of a GCL, advective and diffusive mass flux, and total accumulated contaminant mass through the liner per unit area.

从衬垫底部浓度比、对流和扩散通量、污染物累积运移量等方面，对污染物在GCL中的运移进行了计算。
