查询词典 Zn

The water-scaling rate will increase when the water hardness or temperature is increased. The water-scaling rate will increase slightly when the concentration of SO〓 or NaC1 is increased. The presence of Mg〓 will change the crystallization process of calcium carbonate and produce aragonite scale. The presence of Zn〓 can prevent the formation of the crystal nucleus of calcium carbonate and then prevent the scale.

当水的硬度、温度增加时，水的结垢速率增加；SO〓和NaCl含量增加，能使水的结垢速率略有增加；Mg〓能改变碳酸钙的结晶过程并产生文石状的水垢；Zn〓的参与能明显阻碍碳酸钙微晶核的生成，从而达到阻垢的目的。

It was observed that not only histidine, but also histidine-Co and histidine-Ni could induce and substitute some Cu and Zn from Cu_2Zn_2SOD, eventually influence the activity of this metalloenzyme. Histidine- metal ion complexes have stronger ability than histidine to displace the bound metal ion from SOD. In addition, the amount of foreign metal ion binding to the SOD was less than that of metal ion lost from SOD. It obviously means that there was apoenzyme in the solution.

实验结果表明： Cu2Zn2SOD酶不仅与组氨酸，而且还可以与组氨酸－CoⅡ）和组氨酸－Ni(Ⅱ相互作用，Cu2Zn2SOD酶中的部分Cu和Zn被诱导和置换出来，并相应地影响了酶的活性；组氨酸－金属离子配合物的作用比组氨酸强，酶活性降低也更明显；酶中结合的外来金属离子的量比从酶上被诱导和顶替下来的金属离子的量要少，说明在溶液中有脱辅基酶的存在。

The addition of Cd,Pb,and Zn in the form of acetate salts demonstrated a considerably greater biocidal effect on soil microbial biomass, because of higher solubility of acetate salts.

以醋酸盐形式加入土壤中的Cd、Pb和Zn对土壤微生物生物量比氯化物有更大的毒性，可能与其较高的溶解度有关。

As a unique region in the world, this domain is characterized by its large area （about 900 000 km^2）, many kinds of mineralization （Au, Hg, Sb, As, P, Pb-Zn, U, Ni-Mo-PGE, barite, calcspar, and dispersed elements）, and complicated compositions and associations of ore deposits.

The results indicated that earthworms had greater accumulating ability of Zn than that of Cu.

结果表明，蚯蚓对猪粪Zn有较强的吸收能力，富集系数为1.43；而对Cu的吸收能力相对较弱，富集系数为0.61。

Different contribution of the genes to starch biosynthesisLeaves and developing endosperms of Q319, C7-2, q404, ZN-A and S8 were used to study the expression patterns of 44 genes participating in starch synthesis. We found that ZmGBSSⅠ、ZmSSⅢ、ZmSBEⅡb、ZmBT2-2、ZmSh2-2、ZmSh2-3、ZmBT1 were expressed exclusively in the metaphase and anaphase of developing endosperm, and the expression patterns of ZmSUS1、ZmSus1L、ZmSUS3、ZmSSⅠ、ZmSSⅡa、ZmSBEⅠ、ZmISO1、ZmPul were consistent with the process of starch synthesis in the endosperm, while ZmUGP3 and ZmSUT2 were highly-expressed in all samples, suggesting that these genes perhaps devoted to starch synthesis in endosperm.

淀粉生物合成基因的不同贡献以Q319、C7-2、q404、ZN-A和S8自交系的幼叶、成熟叶、成熟子房、授粉后1d、5d、10d的种子和15d、20d、25d的胚乳为材料，研究了参与淀粉合成的44个基因的表达模式，研究发现ZmGBSSⅠ、ZmSSⅢ、ZmSBEⅡb、ZmBT2-2、ZmSh2-2、ZmSh2-3、ZmBT1在胚乳发育中后期特异性表达，ZmSUS1、ZmSus1L、ZmSUS3、ZmSSⅠ、ZmSSⅡa、ZmSBEⅠ、ZmISO1、ZmPul的表达在淀粉合成期显著上调，ZmUGP3和ZmSUT2在所有组织中高水平表达，说明这些基因可能主要负责胚乳淀粉的生物合成。

In the soils of orchards, the problems such as stronger acidity, higher mass fractions of readily available Fe, lower mass fractions of exchangeable base and deficient trace elements Cu, Zn were found, however, mass fractions of soil were optimum.

柑橘园土壤存在酸性过强、有效Fe含量较高、交换性盐基含量严重偏低的问题；土壤有机质，速效P，水解N含量适宜，而有效Cu，Zn含量缺乏。
