查询词典 Zn

The results show that contents of Zn in bat guano（670.5 mg/kg） is the highest, inferring indirectly the pollution of Zn in the environment around the cave is more serious. Diplopod has not accumulation ability to Ni and Diestrammena marmorata has not accumulation ability to Cr and Ni too.

Investigation was made of the sputtering rate in glow discharge lamp with re-lation to constituent of 25 different specimens of 6 binary systems, namely, Cr-Fe, Bi-Sb,Cu-Zn, Ag-Cu, Al-Zn and Cd-Sn, by measuring mass loss after each sputtering under con-stant Ar pressure and voltage applied. The correlation, in general, between sputtering rate andconcentration of constituent of these non-intermetallic binary alloys obeys the hyperbolic lawunder steady state, yet may be approximately regarded as linear only on certain special condi-tion if the two components of the alloys with similar sputtering rates.

在恒定气压和电压条件下，用测量溅射减量的方法，系统研究了Cr—Fe，Bi-Sb，Cu—Zn，Ag—Cu，Al-Zn和Cd—Sn六个系统的25个试样在辉光放电灯中溅射率与组分的关系结果表明；阴极溅射在稳态时，二元合金的溅射率与组元浓度的普遍关系是双曲线，只有在某些特殊情况下，两组元的溅射率相差不大时，可以近似看成线性关系。

Result Macroelement such as P, K, Ca and Mg and microelement such as Fe, Mn and Zn were abundant in the leaves of A. annua L and the contents of heavy mental elements which were harmful to human were few. The average content of N, K, Ca, P, Mg was 32.6, 31.1, 8.94, 4.14, 3.02 g/kg resp., and the average content of Fe, Mn, St, Zn, Ni and SC was 406, 122.5, 57.7, 52.8, 3.60 and 0.069 mg/kg resp.

结果］黄花蒿叶中含有丰富的P、K、Ca、Mg等大量元素和Fe、Mn、Zn等微量元素，而对人体有害的重金属元素的含量少。N、K、Ca、P、Mg的平均含量分别为32.6、31.1、8.94、4.14、3.02g/kg，Fe、Mn、Sr、Zn、Ni、Se的平均含量分别为406、122.5、57.7、52.8、3.60、0.069mg/kg。

Quantitative analysis of the EXAFS spectra showed that, in a 0 1mol/L NaNO 3 solution of pH 7 5, Zn was adsorbed onto the solid surface by sharing the oxygen atom in the hydrous Zn 2+ ions and in the structural unit MnO 6 on the manganite surface.

结果表明，Zn 水锰矿体系中(pH 7 5 ，0 1mol/LNaNO3 介质，2 5℃)，Zn2 +主要是通过共用水合Zn2 +的O原子及水锰矿表面上的O原子形成Zn—O键，从而结合到水锰矿固体表面上的。

The root dry matter accumulation was affected more intensively by Zn(superscript 2+) than the plumule, and which indicated that the root was more sensitive to exterior Zn(superscript 2+).

结果表明，外源Zn(上标 2+)供应可显著提高幼苗根和芽的干重，对小麦幼苗根的影响大于对芽的影响，根对Zn(上标 2+)更为敏感。

TOF-SIMS images show bacteriogenic pyrites are relatively rich in Cu, Zn, and Ni, suggesting that bacteria probably play an important role in the enrichment of Cu, Zn, and Ni during their formation.

TOF-SIMS 的离子像亦表明菌落成因的黄铁矿富集 Cu 、 Zn 和 Ni ，表明菌落在生物成因黄铁矿的形成过程中，在改变介质条件、在迁移、活化和富集 Cu 、 Zn 等金属元素方面做出了贡献。

The K of Cr, Cu, Pb, Zn, As are more in the sediment than in the organisms. The K of Cd, Zn, Hg are more in the mullet than in razor clam.

Cr、Cu、Pb、Zn、As在沉积物中富集系数高于生物体内，Cr、Zn、Hg、Ph在鲻鱼中的富集系数大于缢蛏中。

Zn and Fe stimulated each other's absorption in roots, but inhibited each other in shoots, while Zn and Mn only had antagonistic effect on each other.

Zn与Fe的吸收在根部似乎表现为互助作用，而地上部表现为颉颃作用；Zn与Mn之间表现出强烈的颉颃作用。

The results showed that the bioaccumulation coefficient of cadmium and zinc in aboveground parts of Bidens tripartite and Solanum nigrum was not less than 1 respectively, and the concentration of Cd and Zn in aboveground parts was higher than that in roots, denoting basic characteristics of hyperaccumulators.

结果表明：狼把草、龙葵地上部Cd和Zn的富集系数均大於1，且地上部Cd和Zn的含量大於根部Cd和Zn的含量，具备了重金属超富集植物的基本特徵。
