By means of static and dynamic experiments, lots of research on the effect of micro-quantity heavy metal ions removal by weakly basic anion exchange resins from drinking water with alkali metals, alkaline-earth metals and anions at high concentration, has been done.

本文采用静态和动态两种试验方法，对弱碱性阴离子交换树脂在碱金属、碱土金属离子以及阴离子相对较高浓度的背景下去除饮用水中微量重金属离子（以Hg2+为研究处理对象）的效果进行了大量试验研究。

In a word, WBAER can effectively remove micro-quantity HMI from DK with alkali metals, alkaline-earth metals and anions at high concentration.

最后得出结论：应用弱碱性阴离子交换树脂能在碱金属、碱土金属离子以及阴离子相对较高浓度的背景下有效地去除饮用水中的微量重金属离子。

Electroless Ni-Co-Fe-P alloys were deposited from a soft alkaline bath, containing boric acid as a buffer agent and sodium citrate as a complexing agent. The effect of the bath pH value on the coating structure was investigated by energy-dispersive X-ray spectral analysis, scanning electron microscope and X-ray diffractrometry.

摘 要：采用H3BO3为缓冲剂、柠檬酸钠为络合剂，在弱碱性体系中化学沉积Ni-Co-Fe-P合金，运用能谱分析仪、扫描电镜和X射线衍射仪研究镀液pH值对合金结构的影响。

MethodsDross were purged from Luohanguo extract with water by ZTC1+1 clarifier, mogroside were isolated by D101 macroporous resin, decoloured on a D301R weak alkaline ion exchange resin.

方法用ZTC1+1澄清剂除去罗汉果水提液中的杂质，以D101大孔吸附树脂分离罗汉果甜苷，D301R弱碱性离子交换树脂脱色。

In weak alkaline medium, the ECL intensity of luminol could be sensitized by potassium ferricyanide. The mechanism of the sensitization is revealed as the oxidation of the luminol by potassium ferricyanide concomitant with the ECL reaction.

在弱碱性介质中，铁氰化钾对鲁米诺具有氧化作用，因而对鲁米诺的电化学发光产生增敏，提高了鲁米诺电化学发光检测的灵敏度，讨论了这一增敏作用的机理。

Effects of Polyvinylamines on drainage and retention of wood mechanical pulp and reed chemical pulp added with CaCO3 were investigated under neutrai papermaking condition.

本研究主要探讨了在弱碱性条件下聚乙烯胺对CaCO3加填的马尾松机械磨木浆和漂白芦苇化学浆的助滤、助留效果。

Relatively thick, highly protective films of boehmite, aluminum oxide hydroxide AlOOH, are formed in water near its boiling point, especially if it is made slightly alkaline, and thicker, more protective films are formed in water or steam at still higher temperatures.

比较厚的薄水铝石，高保护膜，氢氧化铝硬铝石，在水中形成接近沸点，尤其是如果它是由弱碱性，和由于铝生产的氧化形式的腐蚀状况而定，其识别厚，更形成保护膜在水或蒸汽在更高的温度。

Ni 2+ and Co 2+ can be precipitated with Bi 3+ in sulfide when Bi 3+ and sodium sulphide is added to water sample.

在中性或弱碱性条件下，向被测水样中加入适量Bi3＋和Na2S，使水样中的Ni2＋、Co2＋和Bi3＋以硫化物的形式沉淀下来。

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。
