MATHEMATICAL MODELLING OF THE SYSTEM OF UO_2(NO_3)_2-HNO_3 -H_2O/30% (VOL.) TBP-KEROSENE IN SOLVENT EXTRACTION PROCESS——Ⅲ. A MODEL FOR CALCULATING THE DISTRIBUTION COEFFICIENTS OF URANYL, PLUTONIUM NITRATES AND NITRIC ACID
A linearity and good correlation coefficient were yielded from 16.0 to 112.0 μg·mL -1 for isosorbide mononitrate (r=0.999 9),and from 20.0 to 140.0 μg·mL -1 for aspirin (r=0.999 9).
METHODS: Patients ( n =55) with UA were randomly divided into 2 groups: 30 patients [M 21, F 9; age (62 6±12 9) a] in group A received antithrombotic therapy (0 4-0 6 mL nadroparin calcium, sc, bid for 7 d) and isosorbide dinitrate 10mg in 5% glucose 500 mL, iv gtt, qd for 14 d;
The specific surface area is decreasing with hydrogen nitrate concentration increases when its range from 8% to 14%, but when it ranges from 16% to 20%, the changing laws is reverse.
The results show that the depositing speed of the plating solution is between 8.0μm/h~13.5μm/h. The coating layer and base have a good bond. The hydrogen nitrate corrosion resistance time exceeds 60s.
The influences of different hydrogen nitrate concentrations, dipping time, calcination temperatures and sintering time on the samples' physical properties, crystal phase and micro structures were investigated.
When the concentration of lanthanum nitrate was at 300 mg/L and 500 mg/L, and Q of the cultures reached 3.89 and 2.54 times of normal cultures, respectively.
Indium strontium hydrogen nitrate SrIn2[PO3(OH)]4 was synthesized under mild hydrothermal conditions (T = 180 or 200°C) and characterized using IR spectroscopy, chemical analysis, and thermal analysis.
