From the fact that the hydrogens of microbial methane originate in water, it may be deduced that with the reduction of HCO(superscript – subscript 3) a transfer of H atom occurs from the O atom to the C atom within HCO3 anions formed by the disassociation of dissolved CO2 in water, and furthermore, the formyl group forms.

The results showed that Eu(superscript 3+) and Li(superscript +) were successfully doped into the crystal lattice of SrZnO2 matrix and Eu(superscript 3+) preferentially occupied Sr(superscript 2+) asymmetry cationic sites, thus emitting 615 nm red light originated form 5D0→7F2 transition.

结果表明，Eu(上标 3+)和Li成功掺入SrZnO2基质中，Eu(上标 3+)离子在基质中主要占据Sr(上标 2+)离子不对称性格位，发射来源于5D0→7F2615nm为主的红光。

The bacteria did not directly oxidate SO3(superscript 2-), and the oxidization of Fe(superscript 2+) by the bacteria seemed to be the key step if oxidation of SO3(superscript 2-).

在突变菌株与Fe(上标 2+)共存时，SO3(上标 2-)的氧化速率明显高于化学氧化，且以间接氧化为主，细菌对Fe(上标 2+)的氧化是反应过程的限制步骤。

On basis of the color reactions of 4-(2-pyridine azo)-resorcin with copper, zinc and manganese, but the absorption spectrum of complex compounds which they created overlapped with each other seriously. Dealing with the spectrum data with the method of multivariate calibrations of chemometrics, we can simultaneously analyze the measured spectrum of mixture.

基于这三种金属离子均能和4-（2-吡啶偶氮）－间苯二酚发生显色反应，但所生成络合物的吸收光谱重叠比较严重，采用化学计量学的多元校正方法，解析了Cu(上标 2+)、Zn(上标 2+)、Mn(上标 2+)混合物的测量光谱。

The article analyzes change of its ingredients including Ca(superscript 2+), Fe(superscript 2+) 42(superscript 2+) within different process using chemical analysis, iodine amount and testing chemical value ,and prove the conclusion that the method abouve is one of the best ways to process ruddle through experimental data, which may cause ruddle crispy and easy to be smashed, and get the effctive ingredients, and arsenic's amount can be limited as the value require by codex (0.01%).

利用化学分析法、碘量法以及化合价数的测定法来分析代赭石不同炮制品中的Ca(上标 2+)、Fe(上标 2+)、As(上标 3+)的含量变化，通过实验数据来证实煅醋淬法是炮制代赭石最行之有效的一种理想方法，会使代赭石质地最酥脆，易于粉碎，使有效成份最易煎出，最能使炮制品中冲的含量(0.01%)符合药典要求，建议把砷的含量作为股代赭石的一个质量指标。

Citric acid can reduce the Cr(superscript 6+) in sodium dichromate into Cr(superscript 3+) and react with to yield citric acid chromium chelate at 75℃.

在75℃下用柠檬酸将重铬酸钠中的Cr(上标 6+)还原为Cr(上标 3+)，同时与Cr(上标 3+)发生螯合反应，生成柠檬酸铬螯合物。

Analysis based on the experimental results demonstrated the plausible reaction mechanism is that vit C first converts Cu(superscript 2+) to its reduced state and vit C becomes vit C radical itself, thereby stimulating the formation of peroxyl and alkoxyl radicals, and bimolecular reaction of peroxyl radicals results in (superscript 1)O2 production in the systems studied.

根据实验观察的结果，分析了这一体系中(上标 1)O2形成的可能途迳，认为首先是维生素C将Cu(上标 2+)转变为还原态，而自身失去一个电子转变为维生素C自由基，从而刺激了过氧自由基和烷氧自由基的形成，过氧自由基的双分子反应很可能就是体系内(上标 1)O2产生的反应机制。

It indicated that the amidoxime functionalized fiber had large adsorption capacity and high selectivity for uranium.

由对UO2(上标 2+)、Mg(上标 2+)、Ca(上标 2+)3种离子的吸附数据可知，铀／镁、铀／钙的选择性系数分别为20.26和4.01，表明该偕胺肟基纤维对铀具有较强的吸附选择性。

Caudatum was studied. 0.05 mg/L could be the critical mass concn. of P. caudatum fitting to Cu(superscript 2+).Below this concn., the polysaccharide content in P. caudatum was increased in a small range with the increment of mass concn. of Cu(superscript 2+),then the growth and propagation of P. caudatum was strengthened and above this concn., the polysaccharide content was decreased significantly with the increment of mass concn. of Cu(superscript 2+), then the growth and propagation of P. caudatum began to be restrained obviously and the poison was more obvious when the concn.

结果］0.05 mg/L可能是大草履虫适应Cu(上标 2+)的临界质量浓度，低于此浓度时，大草履虫体内的多糖含量随着Cu(上标 2+)质量浓度增大而呈现小幅度的增高，大草履虫的生长繁殖得到增强，高于此浓度时，大草履虫体内的多糖含量随着Cu(上标 2+)质量浓度增大而显著地降低，大草履虫生长繁殖开始明显受到抑制，且浓度越高受毒害越明显。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
