Androgynus was a kind of hyperaccumulator in Cd, with critical value of 50 mg/kg, above which would cause poison in S. androgynus, and even dead when it was up to 800mg/kg; transfer coefficient would decrease with the increase in treated concentrations, which show that plant would protest Cd against transferring to above-grounds and causing poison.

以上结果说明五指山野菜是Cd超积累植物，且50 mg/kg时是五指山野菜正常生长的临界值，高于此浓度，将对其产生毒害，当浓度为800 mg/kg时，植株出现死亡；随处理浓度的增加，转移系数逐渐变小，说明植物在高Cd胁迫下阻止Cd向地上部分转移而产生更严重的毒害。

Analyses of spectral structure and surface tension of solutions suggest that the hydrophobic hardrocarbon chain of surfactants was partly included in the apolar cavity of β-CD and the part with the polar head group of hydrocarbon chain located outside the cavity coiled over the top of β-CD, providing an effective protection for RTP.

组成测定表明溶液中形成了稳定的1：1：1/1-BrN：β-CD：AS三元包合物。光谱和溶液表面张力分析显示阴离子表面活性剂的疏水性烷基链有一部分被包合在β-CD空腔内，未被包合部分则绕曲在β-CD腔口处从而为空腔内1-BrN分子的磷光提供了有效保护。

CD Blaster is a powerful and easy to use CD Burner and CD Ripper in one program.

裁谈会的Blaster是一个强大的和易於使用的CD烧录机和CD开膛手在一个程序中。

ESI-MS results showed that α-CD could form 3: 1 specific complex with cinchonine in solution and they formed"sandwich"structure type 〓 inclusion complex when β-and γ-CD were blended simultaneously with cinchonine. Semi-empirical AM1 calculations indicated that the H bonds formed between CD and cinchonine played an important role to stabilize the complex in gas phase.

电喷雾质谱研究发现α-CD与辛可宁在溶液中可以形成特异性的3：1型复合物，当β，γ-CD与辛可宁同时混合时它们可以形成"三明治"型〓包合复合物，半经验AM1方法计算显示氢键的形成对这些复合物的稳定起到重要的作用。

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 simulated test of compound contamination with Cd and Pb showed that, at a certain concentration, Cd inhibited potherb mustards to absorb Pb, and Pb promoted them to absorb Cd.

Cd、Pb复合污染实验显示在一定的重金属浓度范围内，Cd对Pb的吸收有一定的抑制作用，Pb对镉Cd的吸收有一定的促进作用。

Compared with the single pollution, the eco-toxicity of compound pollution of As+Cd and Cu+Cd becomes stronger, which preemie a synergistic effect, as far as the lethal concentration to the cell of duckweed's lemma is concerned; As+Cu and As+Cu+Cd is inclined to an antagonistic effect of which the eco-toxicity of compound pollution becomes weaker.

与单一污染相比，As+Cd和Cu+Cd复合污染对浮萍叶绿素毒性增强，表现为协同作用，加强了对浮萍叶细胞的伤害；而As+Cu和As+Cu+Cd复合污染对叶绿素联合毒性作用趋向于毒性减少的拮抗作用。

The activity of SOD in grass carp＇s liver and kidney tissues decreases first then increases and decreases once again when Cd^2＋ presents low concentration pollution, while the activity of SOD is inhibited obvious all along （p〈 0.05） when Cd^2＋ presents high concentration pollution.

Cd^2＋低浓度时，肝胰脏和肾脏组织SOD活性均为&先降后升再降&，而Cd^2＋为高浓度时SOD活性始终处于被显著抑制（P〈0.05）；鳃组织在低Cd^2＋污染时SOD活性为&先降后升&，而高浓度的Cd^2＋污染时其SOD活性为&先降后升再降&。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
