In order to meet the needs of the practical industry, the property of ammonium phosphate and the effect of sodium humate on the habitude of slurry was investigated firstly by experiments:the relation between neutralization value of the slurry and the pH value, the relation between the boiling point and the density, water content and viscosity of slurry;the influence of sodium humate added into slurry on the relation between the neutralizing value and pH value, and on the density, water content and viscosity of the slurry.

为了工业的实际需要,通过实验,首先研究了磷铵料浆的性质以及腐殖酸钠对料浆性质的影响:料浆中和度与其PH 值的关系,料浆沸(来源:AB427242C论文网www.abclunwen.com)点温度与其密度、含水量及粘度的关系;添加腐殖酸钠对料浆中和度与其PH 值之间关系的影响,以及对料浆密度、含水量及粘度的影响。

On the basis of Raman and FTIR spectra research on melt structure and water solubility mechanism in albite glasses, we can make the following conclusions:(1) Higher pressure (1bar-2. 0GPa) can lead to below frequency region (50-650cm〓) shift to higher frequency and become narrower, and result in high frequency region (850-1300cm〓) move to lower wave number and become narrower at the same time. These are consistent with the decrease of average T-O-T angle and distribution scope of bond angles (0). In addition, the intensity of 580cm〓 band decrease with increase of pressure and the changes are obvious while pressure is in the range of 0.8-1. 0GPa. And these result from the"collapse"of the planar three membered -containing rings within the glass structure.

通过对高温高压下钠长石熔体结构及水在钠长石熔体中溶解机制的Raman和FTIR光谱实验研究,可以得出以下结论:(1)随着压力升高(1bar-2.0GPa)NaAlSi〓O〓熔体玻璃Raman光谱的低频区(50-650cm〓)不断变窄并向高频方向移动,同时高频区(850-1300cm〓)不断变窄且向低频区方向移动,这表明随着压力升高T-O-T键角不断减小,并且分布范围变窄,T-O-T键角这种变化从而可使T-O键的力常数减小,导致键强减弱;另外,580cm〓谱峰强度随着压力升高不断减弱,并在0.8-1.0GPa时最为显著,这是由于在0.8-1.0GPa时包含的平面三元环结构的"垮塌"造成的。

Chemiluminescent immunoassay is one of the advanced immunoassay ofnon-radioisotopic immunoassay because of its high sensitivity, wide dynamic range,high accuracy, stable labeled protein, full automation and extensive application field.CLIA using acridinium ester derivatives as chemiluminescent label has advantages oflow background, high signal-to-noise ratio, no need of catalyst and simpleluminescence system. Different aspects associating the DMAE·NHS-based CLIA were studied in thisthesis, including synthesis of acridinium ester, chemiluminescentcharacteristics of DMAE·NHS, labelling antibody or streptavidin with DMAE·NHS,two-site sandwich chemiluminescent immunoassay for TSH, two-sitesandwich chemiluminescent immunoassay involved biotin-streptavidinsystem for TSH, and competitive chemiluminescent immunoassay usingbiotin-streptavidin system for TT〓. The desired acridinium ester, DMAE·NHS, was synthesized according to thereference method with some modifications. The products were identified by IR, NMR,MS and elemental analysis. In our method, KOH was used in place of NaOH tosynthesize benzyl ester of 3,5-dimethyl-4-hydroxybenzoic acid,2',6'-dimethyl-4'-(n-succinimidyloxycarbonyl) phenyl-acridinium-9-carboxylate waspurified on a silica gel column with chloroform/ethylacetate(4:1, v/v) as eluent andfurther purified by triturating with hexane/acetone(2:1, v/v).
