For different surface roughness of electrodes and glycol concentration of glycol/water mixture, pressurized water breakdown experiments are carried out. Experimental results suggest that Mirza's formula is valid and independent of surface roughness and glycol concentration, and it is accumulative for surface polish, glycol additive, and pressurization for the capability to improve electrical breakdown strength. Moreover, the increase of electrical breakdown strength of water dielectric for surface polish is explained with bubble breakdown. Especially, highest stress of 235.5kV/cm observed in glycol/water mixture with a glycol concentration of 80% at a hydrostatic pressure of 12atm is about one time greater than that in pure water at constant pressure.

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).
