连二亚硫酸钠

Geochemical analyses include 'total'(concentrated HNO3 -HCl digestion) and chemical forms (three step sequential digestion, reducible, oxidizable and residual forms) of heavy metals Cu, Zn, Pb, Cr,Fe and Mn, iron oxides dithionite-citrate-bicarbonate (DCB and ammonium in the dark extraction as the estimation of total and amorphous iron oxides, respectively, total sulfur and organic matter.

化学分析包括重金属（Cu、Zn、Pb、Cr和Fe、Mn）"总量"（浓HNO3、HCl提取，非严格的总量）、形态（三步提取法，可还原态、可氧化态和残渣态）、氧化铁（连二亚硫酸钠－柠檬酸钠－重碳酸钠提取和草酸铵提取分别估计总氧化铁和无定形氧化铁）、总硫和有机质，并比较了DCB提取前后样品磁性特征的变化。

The effect of white water consistency on hydrosulfite bleaching of DIP and TMP pulps was introduced in this paper.

介绍了纸机白水浓度对DIP和TMP浆连二亚硫酸钠漂白的影响；同时介绍了3种处理和利用白水的研究方案。

Subcordiformis in Huanghai Sea near Dalian, it can be able to evolve H〓 photosynthetically. Comparing with Chlamydomonas reinhardtii in our lab, the H〓 productivity is same. By the elementary macro regulation of H〓 production with 2, 5-dibromo-3-methyl-6-isopropyl-p-benzoquinone , N, N'-dicyclohexylcarbodiimide , 3-(3, 4-dichlorophenyl)-1, 1-dimethylurea , sodium dithionate, sulfur-deprivation and cell immobilization, the results show that DCCD, immobilization and sulfur-deprivation has a positive effects on the H〓 production.

利用DCCD（质子泵抑制剂N，N'-dicyclohexylcarbodiimide）、DBMIB（光合电子传递抑制剂2，5-dibromo-3-methyl-6-isopropyl-p-benzoquinone）、DCMU[PSⅡ光合放氧抑制剂3-（3，4-dichlorophenyl）-1，1-dimethylurea]、连二亚硫酸钠、无硫调控及固定化扁藻等手段，对该扁藻产氢进行初步的宏观调控，发现DCCD的加入、扁藻的固定化和无硫调控对产氢均有正效应，其中无硫调控使扁藻产氢时间延长，总产氢量提高了近10倍。

This paper studied the process parameters in sodium hyposulphite slight bleaching of OCC pulp.

通过正交试验研究了连二亚硫酸钠用于OCC纸浆轻度漂白中相关工艺参数对纸浆光学性能的影响。

Plot of the difference absorbancy at these 3 wavelengths according to the so-called continuous variation method~([7]) clearfly demonstrates the formation of 3 complexes with the proportions of haematin: FMN=1:1, 1:2 and 1:4 in the order of decreasing affinity between the reactants.

老化血红素与FMN反应只能产生1：1的络合物，表现出一个差吸收峰(585mμ)在过量连二亚硫酸钠存在下差光谱形状略为不同，血红素及FMN皆为全还原型时，络合物络合能力降低一个数量级。
