重金属

Influence of different contents of Cd in soil on the growth and yield of triticum aestivum as well as the accumulation of Cd under a potted experiment has been studied.

中文摘 要：采用盆栽试验的方法，研究了土壤中不同镉浓度对小麦生长、结实及重金属镉富集的影响。

The following results were found in the experiments: in pot experiments the diurnal variation of net photosynthetic rateof Lianmeng and Duizhao presented a single-peak curve, and the maximum value occurred at about 12:30, the diurnal variation of net photosynthetic rate of Changlongjie was unregular, the photosynthetic capacity of three treatments from high to low was Lianmeng ＞ Duizhao＞ Changlongjie, heavy metals stress had an inhibitory effect on photosynthesis of plant; There was a significant positive correlation between stomatal conductance and transpiration rate during the diurnal variation(Lianmeng 0.981**, Changlongjie 0.829*, Duizhao 0.87*).

结果表明：在白玉兰盆栽试验中，联盟和对照的Pn日变化呈&单峰型&曲线，峰值都出现在12：30左右，长龙界的Pn日变化无规律，3个处理的光合能力为联盟＞对照＞长龙界，重金属胁迫对植物的光合有抑制作用。

The major phase of both slags produced from air and CO/CO2 conditions were SiO2 and Fe2O3, which have much benefit to the encapsulation of heavy metals. The leaching concentration of zinc in CO/CO2 reducing condition is an order less than that in air oxidizing condition due to the higher vapored heavy metals in CO/CO2 reducing condition compared to that in air oxidizing condition. Furthermore, the leaching rate of heavy metals in both CO/CO2 and air conditions are almost the same.

在熔渣特性改变方面，空气气体与CO/CO2还原气氛下所得之熔渣除外观上不同外，两种熔渣之XRD之图谱因熔渣之结晶程度不良，仅可鉴定出SiO2及Fe2O3两种晶相，因而熔渣中之SiO2及Fe2O3可视为较为稳定之晶体结构，故在还原气氛熔融时，对熔渣中重金属之匣限化仍具有正面助益。

Wacken Open Air is a popular German music festival focusing on various forms of extreme metal and heavy metal.

Wacken Open Air是德国非常受欢迎的音乐节，以有大量不同风格的极端金属和重金属乐队的参与著称。

I wish that when I'm eighteen, I can go to the Wacken Music Festival with a couple of friends and totally 'rock out'.

我希望我十八岁的时候，能够象纪录片上的那个人一样，去德国Wacken的重金属音乐节，不过一定要有几个朋友一起去才好，而且最好有一辆房车。

Sewage sludge contains various kinds of pathogenic bacteria and heavy metals, which may cause serious environmental pollution if without correct dispose. On the other hand, sludge also contains various kinds of nutritious elements which are necessary for plant growth. It would be resources wastement if it is not reasonably utilized.

污泥中含有大量的病原体、重金属等有害物质，如不加以有效的处置，必将产生严重的二次污染；但是污泥中还含有大量的有机物和植物生长所需的营养物质，如不加以合理的利用，又是资源的巨大浪费。

In the agricultural activities, heavy metals from atmosphere,mineral fertilizer, pesticide, wastewater irrigation and industrial waste materialall enter the soil directly and result in the cumulation of cuprum and zincum inlarge amounts in soil.

在农业生长中，来源于大气、矿质肥料、农药、污灌以及工业废弃物的重金属直接进入土壤，造成铜、锌在土壤中大量累积，破坏了土壤环境中的营养元素平衡，降低了农产品的产量和质量，威胁着人、畜的健康。

The extract of Agrocybe Cylindracea was rich in metal elements, including calcium(3.607mg/g), magnesium(3.021mg/g), zincum(79.3μg/g), iron(79.2μg/g).

茶树菇提取物含有丰富的钙(3.607 mg/g)、镁(3.021 mg/g)、锌(79.3μg/g)、铁(79.2μg/g)等元素，对机体有害的重金属元素铅(0.91μg/g)、砷(0.41μg/g)含量相对较低。

The changes of some morphological, physiological and biochemical indexes of the Zizania plant and the Pb2+ residues in Zizania galls were investigated. The results showed that contents of soluble protein, protective enzyme activities, area and chlorophyll content of functional leaves and net photosynthetic rate ascended under low concentration of Pb2+ treatment and descended along with the increase of Pb2+ concentrations, while the content of proline ascended all along.

在不同栽培介质中对重金属Pb2+胁迫的反应，以茭白的单季茭品种'蒋墅茭'和双季茭品种'葑红早'为试材，采用苇末基质和土壤两种栽培介质进行不同浓度Pb2+的胁迫处理，测定了其生长过程中部分形态、生理指标及其产品器官中Pb2+残留含量的变化。

Using a single-harvested cultivar "Jiangshujiao" and a double-harvested cultivar "Fenghongzao" of Zizania latifolia as tested materials, the effects of organic fertilizer and inorganic fertilizer on the binding capacity of different size of Z. latifolia fleshy stem to Cd(superscript 2+) and Pb(superscript 2+).

方法］以茭白单季茭品种&蒋墅茭&和双季茭品种&葑红早&为试验材料，研究了有机肥和无机肥处理的不同规格茭白肉质茎对重金属离子Pb(上标 2+)和Cd(上标 2+)束缚能力的影响。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
