The factor of Cd and Pb speciation in dustfall may be affected by the hunmus ,pH values and the concention of Fe and Mn.

以pH=2.0、pH=3.5、pH=5.0、pH=5.6的淋滤液对24份大气降尘样品进行淋滤实验的结果表明：随着pH值的升高，降尘样的镉和铅的淋出量下降，在pH=2.0时，镉和铅的淋出量最高。

I remembered, from Fe Gang to Ying De, I needed to ride through several tunnels by bike, one of them was 450 meters in length, it was narrow and there was no any lighting in it, only the little bite sunshine from out of tunnel, I was afraid of vehicles, their noises were earsplitting, I was worried about I was bumped, I was worried about if there were some holes in dark tunnel, I was afraid of dropping down into them. I was full of dread and helplessness I never had, in front of me, only a little bit faint sunshine.

我还记得从佛冈到英德，我要穿过几个隧道，有一个450米长的，我走进去非常害怕，周围黑得什么也看不见，我第一次感受大什么叫伸手不见五指，里面又窄又没有灯，只有洞口那一点点光明，我很怕有车进来，那声音震耳欲聋，我担心它撞到我，我有怕里面有个洞我掉下去，心里被一种从来没有的恐惧和无助笼罩着，我眼前只有一点光明。

Using the extended relativistic multi-configuration Dirac-Fock theory and the general-purpose relativistic atomic structure program 2(GRASP2) with quantum electrodynamical effect and breit correction, we have calculated the energy level structures, transition wavelengths, transition probabilities, oscillator strengths, energy level lifetimes, level widths and ionic average lifetimes of As-like Au~(46+), Ge-like Au~(47+) and Fe-like Au~(53+).

根据扩展的全相对论多组态Dirac-Foek理论，采用"多功能相对论原子结构程序GRASP~2(General-Purpose Relativistic Atomic Structure Program 2，1992)"，考虑量子电动力学效应和Breit修正，计算了激光金等离子体中类砷金Au~(46+)，类锗金Au~(47+)和类铁金Au~(53+)的能级结构、跃迁波长、跃迁几率、振子强度、能级寿命、能级宽度和离子平均寿命。

The results show that the mean particle size of α-Fe2O3 monolayer is about 58 nm. There are characteristic bands at 568, 482 and 386 cm~(-1) in IR spectrum. The absorption of 375 nm in UV-Vis spectrum is the electron transition of ferric and oxygen atom.

结果表明，α-Fe2O3单层膜是由粒径约为58 nm的粒子排布而成，在568、482和386 cm-1处有特征红外吸收峰，在紫外区375 nm处存在明显的吸收，为Fe-O间的电子跃迁，其吸光度值与膜层数间的较好线性关系说明在一定的速度下挂膜，可以将氧化铁溶胶中的纳米粒子较好地转移到基片上。
