查询词典 superscript

Continuous culture of immobilized Acidithiobacillus ferrooxidans can be used to remove H2S and SO2. In order to reduce the negative effect of jarosite which formed during the oxidation of Fe(superscript 2+) by immobilized cells, the changing of initial pH and the ingredient in 9K medium were tried.

该固定化细胞的连续培养技术可以用于处理H2S、SO2，为了减少固定化细胞培养过程中带来许多不利效应的黄铁矾沉淀[NH4Fe3(SO4)26]，采取了改变初始pH值和目前普遍采用的9K培养基中的(NH4)2SO4浓度，K2HPO4浓度三种方法。

The results showed: among the three methods, decreasing the concentration (NH4)2SO4 was more feasible than two others. By decreasing the concentration of (NH4)2SO4 from 3g/L to 0.5g/L in batch culture, the forming rate of jarosite was decreased by 50%, while Fe(superscript 2+) oxidation rate was hardly affected.

结果显示：在三种方法中，降低(NH4)2SO4浓度是比较可行的一种方法，当(NH4)2SO4从3.0g/L降低到0.5g/L，Fe(上标 2+)氧化速率几乎没有受到影响，沉淀形成速率却减少了45%。

On the basis of the chemical topological theory, Kier's molecule shape index (superscript mK of 25 chlorinated hydroxyl-phenylaldehydes were calculated in this paper.

基于化学拓扑理论，计算了25种氯代羟基苯甲醛衍生物的分子形状指数

Results IC50 that catechin eliminated O(superscript - subscript 2) and OH was 6.16, 0.59 g/mL respectively, and the eliminating ability of catechin was much stronger than that of the extract from liquorice, rosemary, grape pip, giant knotweed and ginkgo leaf.

结果：儿茶素清除O(上标-下标 2)与OH的IC50分别为6.16，0.59μg/mL，明显优于甘草提取物、迷迭香提取物、葡萄籽提取物、虎杖提取物及银杏叶提取物。

According to the analysis of thermogenic curves, shortened lag phase of bacteria growth, increased growth rate constant and maximum heat power were observed in the presence of Pr(superscript 3+) in low concentration and the results indicated that the growth of E. coli was promoted.

从生成的热谱图分析可以看出，低剂量的稀土离子Pr(上标 3+)的存在可以缩短细菌的停滞期，增加生长速率常数和最大放热功率，刺激大肠杆菌的生长。

The results showed that pH was the most significant factor when dealing with Cu(superscript 2+) by TMT, while other factors just influenced limitedly.

结果表明，pH对Cu(上标 2+)去除效果的影响最为显著，而其他因素的影响则有限。

The results of this study showed that the linalool may lead to increase Fe(superscript 2+) chelating capability.

其结果显示linalool可能是提升SF2、LF2对铁离子螯合能力的主因之一。

The conductivity is lineally increased while the decrease of the diameter of nanowire. Meanwhile, the conductivity of oxidized state and reduced state doped with ClO(superscript - subscript 4) ion is lower than that of partial oxidized state by two order of magnitude.

尚未观察到反向击穿现象，可能原因是，在一定的反向偏压下的离子脱嵌使得它由部分氧化态转变为还原态；电导率随纳米线直径减小而线性地增加；以ClO(上标-下标 4)不离子掺杂的氧化态和还原态比部分氧化态的电导率低二个数量级。

Crops of Brassica napus L., Linum usitatissmum L., Allium fistulosum L. and Lens culinaris Medic. were irradiated by 80 MeV/u 12C(superscript 6+) ion beams with doses of 30, 90 and 180 Gy. The germination rates and heights of seedlings of M1 and M2 generation of these four plants were studied.

以能量为80MeV/u的12C(上标 6+)离子为诱变源辐照油菜、胡麻、大葱和兵豆的干种子后，研究了不同剂量处理对4种农作物M1和M2代种子出苗率及幼苗生长的影响。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
