No coexisting liquid-and gas-rich fluid inclusions were found during quartz petrogaghy microscope observation, the lack of acid hydrothermal alteration mineral assemblages (e. g., alunite, kaolinite, barite, and anhydrite, etc), the measured bulk gas component data of pyrite-and quartz-bearing fluid inclusions distributed cluster on the volatile-temperature diagram, the similarities of the aqueous geochemical compositions among individual low-salinity fluid inclusion decrepited pits detected by SAM/AES and the sulfur isotope profile of a sirngle pyrite stain smoothly changed implied that the ore-forming fluid phase seperation didn′t, contribute significantly to Duolanashayi gold deposit

石英显微观察未发现有共存的富气相和富液相流体包裹体、金矿床明显缺乏原生酸性蚀变组合(如明矾石、重晶石及硬石膏等)、黄铁矿及石英所含流体包裹体实测结果在气相组成-温度相关图上分布较为集中，黄铁矿所含单个低盐度流体包嘉体液相组成俄歇电子能谱分析结果差别不大以及单颗粒黄铁矿硫同位素离子探针线扫描结果变化不明显等宏观与微观地质特征均说明流体相分离对形成多拉纳萨依金矿床的贡献不大

Method］ First of all,esters and lactone reacted with hydroxylamine and formed hydroxamic acid under alkaline conditions; secondly,hydroxamic acid reacted with Fe3+ and generated amaranthine hydroxamic acid-iron complex; finally,esters and lactone contents were measured indirectly at the wavelength of 506 nm.

方法］首先，酯和内酯在碱性条件下与羟胺反应生成异羟肟酸；然后，在酸性条件下异羟肟酸又与Fe3+络合生成紫红色的异羟肟酸铁络合物；最后，在506 nm波长下间接测定酯和内酯含量。

The study of 9－12 indicate that it is easy to get polyoxomolybdate with organic amine at weak acidity conditions when there are organic amine and organic acid in the same reaction systems.

化合物 9－12 的研究结果表明，在弱酸性条件下，同时存在有机酸和有机胺时，易形成含有机胺的钼氧簇，而有机酸不易进入产物晶相。

Filter, wash the precipitate with dilute ammonium hydroxide and then dissolve in 5％ acetic acid to make 10 ml of solution.

分出氯仿液，加酸性乙醇，在520毫微米下比色，測定索拉索丁的含量。

Therefore, the signal of analyte could not be suppressed when using ammonium phosphate in CE/MS.

在酸性条件下，电渗流的速度降到相当低，因此缓冲溶液中的磷酸根阴离子流入质谱的量是非常少的，所以使用磷酸铵的缓冲溶液，并不会严重影响分析物的质谱讯号。

In the process of producing ammonium phosphate, predicting the fluorine content of acidic ammonium phosphate slurry is very significant.

运用RBFN-CSR方法建立了酸性磷铵料浆浓缩过程中氟含量的预测模型，交叉验证表明，该模型具有较高的预测精度和良好的稳定性能，有一定的实际应用价值。

As an amphoteric metal, aluminium reacts both in the acidic and alkaline range, it is therefore important that, when formulating the coating, the pH value is in the 7 - 8 range.

作为一种两性金属，铝反应，无论是在酸性和碱性范围内，因此，这是重要的是，在制定涂料， pH值在7 -8范围内。

By comparing the activity of theα-amylase and the soluble acid invertase in the kernel and the pedicel, the trend of theα-amylase activity in the kernel and the pedicel showed a peak, theα-amylase activity was high in the early stage, it could promoted amylolysis, supply the nutrition for the kernel development; theα-amylase activity was low in the rapid filling stage, it was in favorable to the starch accumulation.

通过比较籽粒和小穗柄中α-淀粉酶和可溶性酸性蔗糖转化酶的活性表明，籽粒和小穗柄中α-淀粉酶活性均呈单峰变化趋势，籽粒发育早期α-淀粉酶活性较高，可以促使淀粉转化，为籽粒的早期的发育提供营养物质；籽粒发育中期为快速灌浆期，淀粉酶活性较低，利于淀粉的积累。

Mature females, in acidic water, compared with male, body color than black, chest, pelvic, anal fin deep red abdomen clearly visible outline of the ovary, and anus highlighted clearly the outer edge of the cloaca, which is crowded as a result of ovarian the result of pressure.

成熟的雌鱼，在酸性水中，与雄鱼比较，体色较黑，胸部、腹鳍、臀鳍的红色较深，腹部可见明显的卵巢轮廓，而且肛门明显突出于泄殖腔外缘，这是由于卵巢挤压的结果。

As roasting temperature rises up to 1000℃, the phase transformation from anatase to rutile finishes.

用该方法得到的TiO2为催化剂，进行可见光催化降解酸性红B的研究。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
