heavy metal element 中文意思是什麼
heavy metal element
解釋
重金屬元素-
After adding la3 + and ce3 +, the enhancement of relative membrane penetration ( rmp ) by heavy metal stress was reduced, the peroxidation of membrane lipids was alleviated and to some degree protected the membrane from injury by heavy metal ions, thus utimately promote the tolerance ability of plants to heavy metal stress. mesurement of element consentration by icp - ms method showed that rare earths could decrease the accumulation of heavy metal ions in the plants through competition effect
在受重金屬離子污染的培養液中施加la ~ （ 3 + ） ， ge ~ （ 3 + ）后，與單一重金屬毒害相比， la ~ （ 3 + ）和ce ~ （ 3 + ）有效抑制了重金屬脅迫引起的細胞膜透性增加，使膜脂過氧化水平減弱，從而延緩了對膜的損傷，最終增強了對重金屬離子的抗性。 -
The results show that the part of the heavy metal element cumulated in root tissue organ on the growth periods and the part of the heavy metal element discharged besides the plant body with the tissue organ of stem and leaf wilted on the growth periods of the anisodus tanguticus ( maxim. ) pascher
結果表明，山莨菪在生長周期內吸收的重金屬元素並非全部蓄積在根組織器官中，部分重金屬元素通過年生長周期內的生長發育而隨著地上莖葉部分等組織器官的枯萎被代謝排出植物體外。 -
Abstract : with the rapid development of industry and transportation ， the pollution of lead ， a widely used heavy metal element being very harmful to human ， has extended from occupational environment to daily environment ， and is being paid more and more attention to. in view of the severity of enviromemtal lead pollution ， harm of chronic lead poisoning to children ' s growth and intelligence development ， and the defects of the agents to remove lead available now ， this paper emphasizes the significance and importance to explore high effective ， no side - effect antidote to chronic lead poisoning ， points that using natural materials to prevent and treat chronic lead poisoning is a significant direction to explore ， and reviews the studies in the area
文摘:本文從鉛污染的生活環境化、低濃度環境鉛污染對兒童發育和智力的阻礙、傳統驅鉛劑存在的問題論述了探索高效、安全、無毒副作用驅鉛劑對防治環境鉛污染慢性中毒的重要性，介紹了國內外利用天然產物防治鉛中毒的研究概況及進展，指出利用天然產物防治鉛中毒是一項很有意義的探索方向。 -
The cultivated anisodus tanguticus ( maxim. ) pascher of two year and three year in different growth phase was collected, and the content of heavy metal element as pb, as, hg, cd was analysed by hydrogen generation - atomic absorption spectrometry
採集兩年生和三年生種植山莨菪在不同生長期的植物全植株，採用流動注射氫化法原子吸收光譜分別測試了其不同組織中鉛、砷、汞、福等重金屬元素含量。 -
Eight heavy metal elements are measured under atmospheric background and dust - sandstorm weather conditions. element - concentration under dust and sand storm is as higher 3. 43 - 6. 30 times as background. six heavy metal elements in precipitation are also analysed and its sharp variation geographically are found
分析了大氣背景和沙塵天氣下的8種重金屬元素濃度和降水中的6種重金屬元素濃度，結果表明，沙塵天氣重金屬元素濃度是背景值的3 . 43 - 6 . 30倍，降水中6種重金屬元素濃度的地理分佈存在不均勻性
