碳酸氢钠

Is the therapy with the bicarbonate effective against all sorts of tumours?

是治疗的碳酸氢钠有效地打击各种肿瘤吗？

Put one and a half tablespoons of sodium bicarbonate in the center of the paper towel.

在纸巾的中央放一大匙半的碳酸氢钠。

Sodium chloride-common table salt-is the most familiar salt; sodium bicarbonate, silver nitrate, and calcium carbonate are others.

氯化钠是最熟悉的盐；其它熟悉的盐类有碳酸氢钠、硝酸银以及碳酸钙。

The results showed that the physical an d mechanical properties of bio-fiber compo sites can be improved though foaming.

研究结果表明：以碳酸氢钠为发泡剂对生物质纤维基复合材料进行发泡可以有效提高材料的物理力学性能。

This modest amount of sodium bicarbonate prevents the potassium depletion and demineralization of bone.

这点碳酸氢钠量即可防止缺钾和骨质脱钙。

NaHCO3 (0.1 M) buffered 0.1 M sodium dithionite (Na2S2O4) at 40 °C was used to release soluble reactive PBD from FeIII oxyhydroxides under low redox conditions.

碳酸氢钠（ 0.1米）缓冲0.1米的连二亚硫酸钠（ Na2S2O4 ）在40 ° C被用来释放可溶性反应PBD从FeIII oxyhydroxides低氧化还原条件。

The influence of each condition on the reaction speed and yield was studied, and the optimal conditions were: the ratio of the amount of substance of aromatic amine and heptafluoro-isopropyl iodine was 1:1.1~1.5, the amount of substance of sodium dithionite, sodium bicarbonate, aniline compounds were respectively 1.1~1.3, the amount of substance of phase transfer catalyst TBAB and aniline compounds was 0.05~0.1, the concentration of aniline compound was 0.5~1.0 mol/L, reaction temperature was 10~20 ℃, and the solvent was aether.

最佳结果为：芳胺与七氟异丙基碘的物质的量比1：1.1~1.5，连二亚硫酸钠、碳酸氢钠与苯胺的物质的量分别为1.1~1.3，相转移催化剂四丁基溴化铵与苯胺的物质的量比在0.05~0.1，溶剂总用量使苯胺浓度在0.5~1.0 mol/L；反应温度10~20℃；溶剂采用乙醚。取代基供电子性越强，反应时间越短，产率越高；氨基的对位优先反应，氨基的邻位较难发生反应；且七氟异丙基总是优先取代在芳环电子云密度较高的位置上。

The changes of total reducing substances, oxalate extractable Fe, dithionite citrate bicarbonate extractable Fe and phosphorus adsorption in oxic and anoxic layers of two paddy soils during 6 week flooding were examined under laboratory conditions.

在实验室条件下对两种水稻土在为期 6周的淹水过程中，其氧化层和还原层土壤中还原物质总量、草酸盐可提取铁、连二亚硫酸钠-柠檬酸-碳酸氢钠可提取铁和磷吸附的变化进行了研究。

Methodssixty four patients were randomly divided into two groups, a and b, with 32 patients in each group. dobell solution was given to those in group a for gargle, six times a day; for those in group b, 50 g/l sodium bicarbonate and dobell were applied for gargle alternatively, six times a day. the infection was observed one and two weeks later.

随机抽取大剂量化疗后成年白血病住院病人64例，随机分成a、b两组，各32例。a组给予多贝尔液漱口，b组给予多贝尔液及50 g/l碳酸氢钠液交替漱口，每天6次。1、2周后观察两组口腔真菌感染发生情况。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
