查询词典 The Heavy

By using the generalized central limit theorem, the heavy-tailed distributions (heavy-tailed Rayleigh distribution for amplitude image and heavy-tailed exponential distribution for intensity image) are obtained from the symmetric stable distributions of real and imaginary parts of echoes. Taking the heavy-tailed Rayleigh distribution as an example, the algebraic tails of heavy-tailed distributions are explained as well as the statistics of sharp peak and heavy tail.

Based on the evaluation system, the plants whose relative remediation age was between 0~10 years were named as"Hyperaccumulator"and those between 10 ~ 50 years were named as"Accumulator".7 In the experiments six kinds of substrates were mixed with different solid wastes and the absorption and enrichment of plants on heavy metal Cd was studied. The results showed that relative remediation age was an ideal index to evaluate the capability of the phytoremediation on heavy metals, because it took into account more factors which affected the absorption evaluation effects than others, such as the heavy metal content and the biomass of the over-ground part of plants, the heavy metal content and the whole gross in substrates, harvesting frequency of plants and the environment standard of heavy metal. This made relative remediation age be suitable to the sorption capability evaluation of not only different plants on one heavy metal but also one plant on different heavy metals.8 It can be drawn from the relative remediation age of heavy metal Cd that the absorption capability of different plants was not same.

At the heavy metal concentration of 3-4ppm, our study on adsorption capacity, adsorption selectivity of montmorillonite, illite and kaolinite to Cu〓、 Pb〓、 Zn〓、 Cd〓、 Cr〓 shows that the adsorption capacity is mainly determined by the capacity of exchangeable cations and the adsorption capacity of the three clay minerals decreases in this sequence: montmorillonite ＞＞ illite＞kaolinite. It is found that clay minerals have obvious adsorption selectivity to various heavy metals. Montmorillonite exhibits a stronger affinity to Cr〓 and Cu〓 while kaolinite and illite sorb Cr〓 and Pb〓 more effectively. At the same heavy metal concentration, adsorption amount of clay minerals to heavy metals increase with increasing pH value of the solution.

It is revealed in the study that the heavy metal concentration of Pb,Cu,Zn in the leaves of urban trees (Sabina chinesis,Platycladus orientalis,Euonymus japonicus,Platanus acerifolia, Prunus cerasifera) is significantly related with the relative heavy metal contents in atmospheres of different urban regions of Yantai city, while no such relationship is found in heavy metal Cd, and that the heavy metal amounts of Pb,Cd,Cu,Zn in urban soils had no direct impacts on the heavy metal concentrations in leaves of urban trees.

通过对烟台市区不同大气污染区域绿化植物叶片中重金属Pb，Cd，Cu，Zn富积量和大气与土壤中相应重金属的含量研究分析发现，植物叶片中重金属Pb，Cu和Zn的富积量与大气中Pb，Cu和Zn的相对含量呈显著的正相关，而植物叶片中Cd的富积量与大气中重金属的相对含量相关不显著。
