吸收系数

There was a low accumulation of Pb in Pelargonium horlarum. When the Pb concentration in soil was increased by 1500 mg/kg, the Pb was accumulated by 169.5 mg/kg only. The plant content of Pb was lower than the hyperaccumulator critical content. The shoot' accumulation of Pb was significantly higher than that of root.

随着土壤中铅浓度增加，与对照相比，生物量在铅浓度增加1000 mg/kg时，才有显著下降；但对铅的吸收量较低，当土壤中铅浓度增加1500 mg/kg时仅吸收169.5 mg/kg；地上部分吸收量远小于地下部分的吸收量，转移系数小于0.5。

宝石透明度的含义与分类宝石透明度与矿物的一样，均是指其透过可见光波的能力，主要与它们对光的吸收强弱有关，其大小可用透射系数来说明。

Analyses show that refractive index changeinduced by thermal effect is similar to the change induced by other effects for linearabsorption,if laser pulse width is far less than the characteristic time of sample,i.e.refractive index change is directly proportional to spatial part of incident pulse laserintensity,so time averaged nonlinear refractive index can be defined.

结果表明，当激光脉冲宽度远小于被测样品的特征时间时，对于线性吸收来说，其热效应产生的折射率变化与其它效应产生的折射率变化有类似的形式，即与入射脉冲激光光强的空间部分成正比。因而可定义时间平均非线性折射率。在这种情况下，可用通常的Z-scan法进行非线性折射率及热光系数的测量，所得结论符合以前的实验结果。
