连二亚硫酸钠

By addition of suitable amount of sodium hydrosulfite into blood samples which were diluted by 0.1% Na2CO3, the absorption curve from 400 nm to 600 nm and absorbance at 419 nm and 425.5 nm of the blood samples were detected for qualitative and quantitative determination of carboxyhemoglobin.

检血用0.1% Na2CO3稀释后加入连二亚硫酸钠，用紫外－可见分光光度计测定500nm-600nm吸收光谱图和419nm及425.5nm处的吸光度值，对碳氧血红蛋白进行定性和定量分析。

This paper describes two methods of 4th derivative spectrophotometryfor the determination of carboxyhemoglobin in blood.Both of them areaccurate,precise and reliable.

一氧化碳中毒血液经连二亚硫酸钠还原后成为可见光区碳氧血红蛋白和还原血红蛋白的二元吸光物质体系。

The combined ether layers were treated with sodium dithionite and washed with water (10 mL).

合并醚层治疗连二亚硫酸钠和水洗（ 10毫升）。

In this study, Fe and sodium dithionite solutions were added into Cr-spiked soils and their effects on the decrease of availability of Cr were investigated.

本研究旨在探讨将Fe或连二亚硫酸钠（Na2S2O4）等化学还原剂施於Cr污染之碱性土壤，降低有效性六价铬含量的效果。

Mmol/L. The activity of this catalase was not reduced by dithionite but was strongly inhibited by cyanide, azide, and 3-amino-1,2,4-triazole (the specific inhibitor of monofunctional catalase).

该过氧化氢酶不受连二亚硫酸钠的还原作用影响，但被氰化物、叠氮化物和3-氨基-1，2，4-三唑(单功能过氧化氢酶的专一抑制剂)强烈抑制。

These methods include hydrogenation in high-pressure,reduction by hydroborates and reduction by dithionite. This article studied these methods, especially optimized the technology of hydrogenation in normal pressure and reduction by hydroborates.

研究了常压氢化法、加压氢化法、硼氢化物还原法及连二亚硫酸钠还原法等制备四氢叶酸，并优化了常压氢化法、硼氢化物还原法的工艺条件。

The mechanism was supposed as follows: polyfluoroalkyl iodides were initiated by sodium dithionite to give R〓 which was added to one double bond of diallylacetic acid, after the sequential radical cyclization and nucleophilic substitution to form bicyclo-lactones.

这是因为：多氟烷基碘化物在连二亚硫酸钠的引发下，得到自由基R〓，后者加成到二烯丙基乙酸中的一个—C=C—双键上，然后在碱性介质中进行分子内亲核反应得到双环内酯类产物。

Methods: hypoxia model of detrusor smooth muscle cell in vitro was established by sodium hyposulfite which consumed the oxygen of the medium. the cx43 and cx43 mrna were detected by western blot and rt_pcr. the level of malondialdehyde was detected.

体外培养膀胱逼尿肌细胞，用连二亚硫酸钠清除培养基内的氧，建立缺氧模型，通过rt_pcr、western blot检测正常对照组、缺氧组及vite预处理组的逼尿肌cx43表达情况，并检测丙二醛质量浓度。
