The digital analysis of the six standard samples of the Al-based alloy with different content of Cd, and the probe into the quantitative analysis that employs the spectrums of Cd 508.5 nm as the analysis spectrum, Cu510. 55 nm and Fe510.75 nm as comparison spectrum separately, indicate the positive relationship between the content of cadmium and the intensity ratio of the analysis and comparison of spectrum.

对6种不同Cd元素含量的铝合金标准样品进行了数字化分析测定，探索了选用Cd 508.58nm谱线作为分析谱线，分别选用Cu510.55nm和Fe510.75nm谱线作为比较谱线进行定量测定的方法，数据显示分析谱线和比较谱线的强度比值与Cd元素含量成正比关系。

The result of acute toxicity of Cd(superscript 2+) on antioxidant enzymes showed that along with the rise of concentration of Cd(superscript 2+), the activity of superoxide dismutase, catalase, and guaiacol peroxidase were changed in O.chinensis injected with Cd(superscript 2+).

对Cd(上标 2+)急性染毒的中华稻蝗抗氧化酶活性变化研究表明，随着Cd(上标 2+)浓度的升高，超氧化物歧化酶、过氧化氢酶、谷胱甘肽过氧化物酶活性均发生改变。

Cu、Ni、Pb and Cd showed more affinity to the oxidizable metal fraction. Bio-availability of all the measured metals, except Cd,decreased with the increase in composting time. Therefore, we conclude that composting could stabilize the heavy metals present in the sludge and decrease the risk of soil pollution.

污泥堆肥中Cu、Ni、Cd、Cr主要以残渣态形式存在，Cu、Ni、Pb、Cd四种重金属元素的可氧化态含量也相对较高，除Cd外，经过堆肥化处理后所有重金属的有效态含量均呈下降趋势，因此，堆肥可以促进污泥中的重金属稳定化，降低土壤的污染风险。

The content of praline and activities of superoxide dismutase and peroxidase were increased under Cd stress. The increase of proline content and POD was more pronounced in the xiushui 63 under lower level of Cd, however, it was more pronounced in the Xiushui 09 under higher level of Cd.

总体上，脯氨酸含量、超氧化物歧化酶、过氧化物酶活性均呈上升趋势，其中，在较低浓度Cd胁迫下，秀水63叶片中脯氨酸含量、POD活性增加幅度较大，而在较高浓度Cd胁迫下，秀水09的增加幅度较大。

To boot from the CD image ''', write it as an image to a CD or DVD recordable / rewriteable disc using your preferred CD / DVD writing software, then reboot with the disc in the drive.

从CD镜像启动'''，把它作为一个镜像用你喜欢的光盘刻录软件刻录到可以刻录的CD/DVD 光盘上，并把光盘放在光驱中，重启计算机。

The signals of inner H-3 and H-5 of CD shift upfield uponaddition of DBBAB, it show that BDDAB interact with CD. The chemical shift of thebenzene ring of BDDAB molecule are changed after interacting with α-, and β-CD.

随着BDDAB浓度的增加，CD的H-3，H-5的化学位移向高场移动，说明BDDAB与CD发生了相互作用。

First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

首先，本文从理论上对坩埚下降法生长碲锌镉单晶体中的成核、Zn分凝、几何淘汰生长与温场等关键性问题进行了讨论，对在生长过程中可能出现的各种缺陷类型和形成原因进行了详细分析，提出了碲锌镉单晶体生长过程中Cd空位缺陷控制原理及方法，并针对坩埚下降法生长特点自行设计了两区域独立加热管式生长炉，获得具有较好线性分布的温场。

The results showed that Pb, Cd and Cu in the leaves of plants were positively related to their concentration in air significantly. The content of heavy metal in plant leaves was obviously associated with the heavy metal properties, pollution conditions and tree species. Platanus hispanica had a higher accumulation in Pb, While Populus deltoides in Cd and Cu.

研究表明，植物叶片中重金属Pb、Cd和Cu的累积量与大气中Pb、Cd和Cu的相对含量呈显著正相关；所调查绿化树种叶片的重金属含量因重金属种类、采样区和树种的不同具有明显差异，悬铃木叶片累积Pb的能力最强，而杨树叶片对Cd和Cu的累积能力最强。

However,compared to Cd~(2+) stress alone, treatment of SNP+Cd~(2+) caused more increases in SOD,CAT and POD activities, a decrease of H_2O_2 level and MDA content in leaf and root ofmung bean seedlings. These results indicated that exogenous NO induced increases inSOD, CAT and POD activities, which scavenged H_2O_2 and resultantly inhibitedmembrane lipid peroxidation in leaf and root of mung bean seedlings under Cd~(2+) stress.

说明NO通过诱导膜保护酶活性的提高，降低了活性氧水平，从而使Cd~(2+)胁迫诱导的膜脂过氧化程度降低，这可能是外源NO明显缓解Cd~(2+)胁迫抑制绿豆幼苗生长发育的原因之一。

In the present study,growth responses of Rorippa globosa and its accumulation characteristics of Cd and As were examined under the condition of Cd-As combined pollution.

结果表明，在低浓度Cd-As复合污染条件下，由于Cd、As的拮抗作用，从而促进植物的生长发育，同时也促进地上部对Cd的吸收和积累。
