污染

Eco-toxicology effects of compound stress of Cu, Cd, Pb, Zn and As on growth, chlorophyll content and protective enzyme of Juncus Effuses were studied using pot culture. Concentrations of the heavy metals in the soil were designed according to the State Soil Environmental Quality Standard. Considering practical application, soils contaminated with tailings and wastewater from Lead/Zinc mining were also used in the experiment.

通过盆栽试验，以现行土壤环境质量标准为浓度设置依据并结合实际污染土壤研究了不同处理水平的Cu、Cd、Pb、Zn、As 5种重金属复合污染对灯心草生长、叶绿素含量及保护酶系统的影响。

It still can be quickened river, river, laky the inorganic that waits for deposit of oxygen of bad news of riverbed bottom mud changes a course, on the spot eliminates bottom dirt to catch, pick up oxidation is reductive, prevent the pollution that dredge causes.

它还可以加速江、河、湖泊等河床底泥耗氧沉积物的无机化过程，就地消除底泥污染，回升氧化还原，避免疏浚造成的污染。

Owing to the influence of industry sewage, living sewage, the lixiviate things of soil in the wet-dry zones and the falling of water self clean ability, the water quality of reservoir will be influenced and the fluctuation in stage will share a inverse relationship with the regression of river level in the natural state.

由于受到陆地污染物的进入、淹没地污染物的浸出以及水体自净能力下降的影响，消落带水环境存在着岸边污染带和水陆交叉污染两方面的问题，将严重影响库区水环境质量，扰乱该地区原生生态系统，影响三峡库区生态环境安全。

Because the core mass of the AGB star is remarkably large at low metallicity.

对于AGB星初始质量小于3M_☉且初始轨道距离较远的双星系统，白矮星不能从受污染的星上吸积充足的物质，因此不能形成AIC，其伴星只受到AGB前身星的污染，从而形成s-过程元素超丰的星。

RESULTS: There was significant difference in micronuclear rates of every site(P.01). PI values of 7 among 9 sampling sites were over 2.00. The micronuclear rates were higher in the sites with higher PI.

结果： 各采样点水样的蚕豆根尖细胞微核率均高于对照组(P.01)，9个采样点中有7个采样点的污染指数在2以上，污染指数高的水样组细胞微核率也高。

The experimental results show:(1) The water in South Fei River has been comtaminated, especially in industrial and residential part.(2)Vicia faba(QI_1) is sensitive to mutagen, and liner relation between the freguency of micronuclear cell in the root tip cells of Vicia faba(QI_1)and concentration ...

结果表明，南淝河水体已被污染，尤其以工业区和居民生活区污染严重；启豆Ⅰ号对诱变物反应敏感，水环境中污染物浓度与微核千分率呈线性相关，因此启豆Ⅰ号作为微核监测技术的实验材料是可靠的。

The utility model discloses a mudproof sole, aiming at solving the currently existing problem that upper and head of a sole get dirty by mud water easily.

本实用新型公开了一种防泥水污染的鞋底，以解决现有鞋底存在的鞋帮和鞋头被泥水污染的问题。

The results provided basis for the application of mycorrhizal technology to bioremediation of mineral oil contaminated soil.

研究结果为矿物油污染土壤的菌根生物修复提供了理论指导和科学依据，为菌根技术在有机污染土壤生物修复中的应用提供了借鉴。

In the whole growth cycle of corn,Influence on corn growth is stronger under soil Naphthalin pollution stress in seedling.

从土壤萘污染对玉米整个生长周期的影响看，土壤萘污染胁迫对玉米苗期影响较

In corn grouting stage, Trend of photosynthesis is almost the same as seeding and jointing stage under soil Naphthalin pollution stress.

从土壤萘污染对玉米的各个生理生化指标看，低浓度土壤萘污染胁迫对玉米地上

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。
