Amodel for the crystal growth of molecular sieve zeolite in the system of non-spontaneous nucleation was developed on the basis of the liquid-phase mechanism. 27 curves of crystal growth of L, Ω and ZSM-5 type zeolites were calculated by using the method of computational mathematics. The fact that the calculated curves are consistent with the experimental values shows clearly that the model is of values to explain the process of crystal growth of zeolites, particularly, the stage at the end of crystal growth (the previous other models can not explain experimental curve at this stage). At the same time, some parameters concerned are discussed.

In this parper, a sort of new rare earth color reagent-polyhalogenated bisazo chromotropic acid derivcnts have been designed and synthesized. They are easily soluble in water, alcohol and acelone, but insoluble in benzene, ether and chloroform. The absorption maxima of arscnazo or carboxyazo types reagents are at about 527-540nm and chlorophosphonoazo type at 543-549nm. The absorption maxima of the complexes of reagents with rare earth elements are at 628-650nm.The color reagents can react with rare earth elements not only in weak acidic medium (pH = 2-5), but also in strong acidic solution (such as 0.1-4N HCl, H

DNAis complexed with tetrazolium cations (Blue tetrazolum, BT) and then mixed with collodion and finally adsorbed on the macroporous spherical carbonaceous polymeric adsorbents. The percentage of DNAthus immobilized is 98-98.5%. It was applied to animal hemoperfusion for the removal of the DNAantibodies and its immune complexes which were passively infused. After 10-20 minutes adsorption, a sharp reduction of DNAbinding was observed and the futuin (AFP) binding percentage only dropped slightly. The efficiency of the specific removal of DNAimmune complex was over 75% and only less than 10% unspecific adsorption occurred. Tt has a good stability and blood compatibility. Therefore, it might be applicable 1o clinical SLEtherapy.

The thesis is primarily based on dichlorotelechelic polybutadiene-1,2 prepared first by using naphthalenelithium as initiator, extracted naphtha as solvent, butadiene as monomer, trichloroazine as terminator. Then acetic acid or alcohol or sodium hydroxide was used to hydrolyze dichloro telechelic polybutadiene-1,2 to obtain thecorresponding end product--telechelic cyanuric acid terminated polybutadiene-1,2.The latter was studied in detail by ultraviolet, infrared spectrum and acid-base potential titration. Not only the molecular structure of said prepolymer was testified but also the phenomenon of alcohol-ketone (lactam-lactim) tautomerism present in polymer solution was discovered as well. They were measured quantitatively, too.
