metal abundance
解釋
金屬豐度-
Taken two heavy metal contaminated soils in copper mine field of hongtoushan area and lead - zinc mine field of qingchengzi area as sampling sites, studied the abundance and diversity of amf community and the relation of which to ecological factors ; two experiments were managed by pot culture and four - compartments culture system with festuca. rubra and red clover as host plants inoculated with gintraradices, gmosseae and gcaledordinum to study the effect of different amf on the uptake and accumulation of heavy metal in cd contaminated soil and cu > zn - pk cd complex - contaminated soil
採用盆栽、四室根箱培養的方法，研究了接種g . intraradicesg . mosseae和g . caledordinum在cd污染和cu 、 zn 、 pb 、 cd復合污染土壤中對紫羊茅、三葉草吸收、累積重金屬的影響，明確了叢枝菌根菌在重金屬污染土壤生物修復中的作用。主要結果如下： 1 、沈陽礦區重金屬污染土壤中，共發現叢枝菌根菌6個屬23個種，已鑒定22種， 1個未定種。 -
The average abundance distributions of heavy elements in metal - poor stars can provide fairly direct and detailed information on the nucleosynthesis in every stage after the formation of galaxies. furthermore, it can put more accurate constraints on the chemical evolution of neutron - capture elements. the solution to this problem will have important effect on the solution to a series of problems about nuclear astrophysics and the galactic evolution
貧金屬星的中子俘獲元素豐度分佈能提供星系形成后各個階段核合成的較為直接和詳細的信息，並為星系化學演化的研究提供更為準確的約束，這一問題的解決將對核天體物理及星系化學演化的一系列問題的解決產生重要影響。 -
Thus the cumulative consequence of galactic chemical evolution starting from low metallicity agb stars, namely, the average abundance patterns of sbh part with 140a204 ( or the snl component part with 92a132 ) in different metal conditions, should be similar ( ornearly similar ) to the corresponding solar s - bajn component
低金屬豐度條件下，由於中子輻照量隨金屬豐度的降低而升高， s _ （ ml ）產量低於s _ （ mh ） 。雖然s _ （ ml ）分佈與太陽系有差異，但對于質量范圍92 a 132 ，任何金屬豐度下分佈與太陽系大體相似。 -
Based on studies of such geochemical characteristics of songxian county area as natural climatic and soil features, major and minor elements of parent rocks, physical and chemical properties of soil, total content of nutritive elements, effective state of nutritive elements and distribution of heavy metal elements, this paper deals with the background of soil agricultural geology, abundance and shortage of nutritive elements and soil environmental quality in this area, thus pointing out the way forward for agricultural production and adjustment of production structure
摘要通過對自然氣候、土壤特徵、母質（巖）常量元素、微量元素、土壤理化性狀、營養元素全量、營養元素有效態、重金屬元素分佈分配特徵的研究，闡述了嵩縣土壤農業地質背景和營養元素豐缺及土壤環境質量，為農業生產和產業結構調整指明了方向。
