查询词典 sodium

The conclusion was drawn by the synthesis of molecular sieve: after mixed soluble glass and aluminium sulfate with proper proportion under room temperature, it was stirred stormily to react. And then we mixed with potassium hydroxide solution after filtrating. At last, the molecular sieves of potassium type was synthesized after the mixture reacted in the oven or autoclave for 24 hours. The molecular sieve was remodeled more than twice with ammonium chloride solution that the concentration was 3mol/L and then remodeled twice with the saturated sodium chloride solution. Finally the molecular sieve was changed into the sodium type. It was named W zeolite.

通过对分子筛的合成得到：以泡花碱、硫酸铝为原料，以硅铝比按一定比例于室温下将二者混合，激烈搅拌，抽滤后与氢氧化钾溶液混合放于烘箱或高压釜中高温晶化24小时，晶化后的分子筛为钾型，先后用3mol/L氯化铵溶液和饱和食盐水各对其改型两次以上，最后改为钠型，可制得W型沸石分子筛。

So a spectrophotometric method is developed for the determination of sodium nitroprusside in the injection solution of sodium nitroprusside.

由此建立了测定硝普钠注射液中硝普钠含量的新的分光光度分析法。

The spores of Cheilolejeunea ventricosa X.L.He were cultured on MS media (without acid and vitamin, pH=6.2, with 1% agar and 1% sucrose). The sporeling development and oil body ontogeny were observed. After a 55-day-long axenic culture, young plants were obtained successfully. Sodium hypochlorite solution was used to sterilize the capsules. Our results revealed that the sterilizing treatment with 0.1% Sodium hypochlorite solution for a period of 5 seconds was optimal. Oil bodies in primary protonemata are nearly homogeneous, but distinctly compound in the leaf cells of the primary leafy shoots.

首次研究了膨叶唇鳞苔的孢子萌发、原丝体和油体发育及配子体发生的过程，结果表明：(1)使用经过改良的MS培养基（不加氨基酸和维生素，pH值为6.2，琼脂和蔗糖浓度均为1%）能在55 d左右的时间利用孢子培养获得植物体；(2)用0.1%的次氯酸钠溶液，消毒5 s是消毒孢子的最佳方案；(3)油体在孢子萌发初期为均一型，到幼叶发生后，成为可见的聚合型，但聚合的程度比野生材料要弱。

Fluoride with sodium fluoride, potassium fluoride, stannous fluoride and sodium monofluorophosphate.

氟化物有氟化钠，氟化钾，氟化亚锡及单氟磷酸钠。

The sodium, for example, should glow in the orange part of the spectrum, like a giant but very faint sodium vapor streetlamp .

例如，钠在光谱中呈现出橙色光，就象一盏巨大而非常暗淡的钠汽灯。

However, sodium hydroxide enhanced the amount of SO2 treated via the formation of sodium sulfite.

但附着的氢氧化钠可通过生成亚硫酸钠，提高对二氧化硫的除去效果。

The effect of various concentration of surfactant and sodium dodecylbenzene sulfonate on the aqueous photodegradation of sodium pentachlorophenate were studied.

研究了不同浓度的阴离子表面活性剂十二烷基苯磺酸钠对五氯酚钠在水溶液中光解的影响。

In order to improve their water solubility, 4"-fatty amido-3"-sodium carboxylate azobenzene-4-sodium sulfonates were synthesized. They are azo compounds with two hydrophilic groups of carboxyl and sulfonyl. They decrease the surface tension in dilute solution slowly, and show some surfactivity, but are not surfactants. The probable reason is their relative strong hydrophile. Furthermore, their colors are not fresh and far from our destination.

为了改善其水溶性，改用对氨基苯甲酸为原料合成了4′-脂肪酰氨基-3′-羧酸钠偶氮苯-4-磺酸钠盐，以偶氮结构为主的亲水基团上连有羧酸基和磺酸基两个亲水性较强的基团，但可能由于其亲水性太强，在稀溶液中只能缓慢地降低溶液的表面张力，具有一定的表面活性，但不是表面活性剂，而且颜色不鲜艳，距离我们的目标较远。

The company's main products are: anhydrous sodium sulphite (10000 T /), Gioia sodium (20000 T /), manganese carbonate (1000 T /).

本公司主要产品有：无水亚硫酸钠（10000T／年）、焦亚硫酸钠（20000T／年）、碳酸锰（1000T／年）。

Seven central depressants,including chloral hydrate,potassium bromide,sodium bromide,cal- cium bromide,alcohol,amytal and chloretone, were studied for their effects on the intraperito- neal toxicity of tartar emetic and sodium stibo- gluconate in mice.

1。关于吐酒石与葡萄糖酸锑 V 钠对小白鼠的致死作用，我们探索了一些中枢抑制药与兴奋药的影响。所试的抑制药有水合氯醛，溴化钾，溴化钠，溴化钙，酒精，安眠妥与三氯叔丁醇七种。兴奋药有苯甲酸钠咖啡硷与士的宁二种，以及溴咖合剂。2。
