以对苯二酚生产中副产物含锰废水为原料，研究了生产高纯碳酸锰时除杂质钠盐与硫酸根的工艺，并研究了影响杂质含量的诸因素，如温度、锰离子浓度、加料方式等。

If impurity or degradation product standards are unavailable, specificity may be demonstrated by comparing the test results of samples containing impurities or degradation products to a second well-characterized procedure e.g.: pharmacopoeial method or other validated analytical procedure.

如果杂质或降解产物的标准品不能够得到，专属性可以通过比较含有杂质或降解物的样品的检测结果和另外的完好的分析方法，如，药典方法或其它验证的分析方法的结果来证实。

The general chapter 5.10 of the European Pharmacopoeia "Control of impurities in Substances for Pharmaceutical use" and the revised general monograph 2034 Substances for pharmaceutical use introduce new requirements (as also described in the guideline CPMP/QWP/1529/04 Control of impurities of Pharmacopoeial substances) that should be consulted to understand how to read the limits of the monograph and how to apply the general monograph when setting specifications.

欧洲药典总章5.10&药用物质中杂质的控制&和修改后的总论2034药用物质介绍了新的要求（在指南CPMP/QWP/1529/04 药典物质中杂质的控制），应参考这些新的要求，弄明白如何读专论的限度，以及在设定质量标准中如何使用总论。

The re are many methods to exam special impurity in drugs,including spectroscopy,stratography and multiple techniques.

归纳了药物中特殊杂质检查的多种方法，包括光谱法、色谱法以及联用技术等，为药物中特殊杂质的检查和药品质量控制提供参考。

Now,the method of dynamics is used in normal applications by measuring the sulphation degree of the solid calcium oxide to infer the reaction activity of limestone;but it is not enough on condition of many types of impurity the limestone composition,which has considerable influence on the desulphurization reaction activity of limestone.

目前，国内外主要采用动力学方法，通过测定固态CaO的硫酸盐化程度来推断石灰石的反应活性。但是这在石灰石中含有许多其它杂质成分时是不够全面的，因为这些杂质成分对石灰石的脱硫反应活性影响很大，不能忽视。

The effect of impurity H2SO4 in the simulating wet-process phosphoric acid on the rheological behavior of the ammoniated slurry was studied.

用化学试剂配制不含铁的模拟湿法磷酸，在其铝，镁，氟杂质浓度固定的条件下，改变硫酸杂质的浓度，在50 ℃下测定其氨化料浆的流变曲线。

If there are impurities in the air, they may be absorbed by our bodies and make us ill.

假如空气中的杂质，这些杂质会被我们的身体吸收，使人生病。

Secondly, the energy band structure of codoped-TiO2 shows that an acceptor level and a donor level present inside the band gap, and an electron on the donor level passivates a hole on the acceptor level, so the systems still keep semiconductor character and enhance the separation of electron-hole pairs excited by photo irradiation.

另外， V： N共掺杂TiO2的能带结构表明：导带底下方施主杂质能级上的一个电子刚好补偿价带顶上方受主杂质能级上的一个空穴，使掺杂后TiO2材料表现出半导体的显著特征，这有利于电子—空穴对的分离，提高量子产率。

Other impurities (e.g., inorganics, residual solvents) should be addressed and quantitated.

对于其它杂质(如无机杂质，残留溶剂)，应当要进行说明并定量分析。

In general as long as the temperature reaches 90 ℃, the common E. coli, hepatitis B virus and other bacteria have already perished, but we still continue to boil water, this area is to allow water in the calcium carbonate, magnesium carbonate and other ingredients to fully precipitate impurities, and the other On the one hand, because I am using tap water is treated with chlorine, so a certain degree of residual chlorine in water, in the process of boiling water, chlorine and impurities in the water will generate harmful substances called chloroform.

在一般的长期的温度达90℃，普通大肠杆菌，乙型肝炎病毒和其他细菌已经死亡，但我们仍烧开水，这方面是允许的碳酸钙，碳酸镁和其他水成分，杂质充分沉淀，以及对其他一方面，因为我使用的自来水是用氯处理，因此在水中的余氯，在一定程度上开水，氯和水中杂质的过程中，将生成所谓有害物质氯仿。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
