摘      要：Systematic CR-39 bulk etching experiments were conducted over a wide range of concentrations(2–30 N)of NaOH-based *** analysis and a deep discussion of the results are presented.A comprehensive nuclear track chemical etching data bank was *** regimes of CR-39 bulk etching were *** I spans etchant concentrations from 2 to 12 *** II spans concentrations from 12 to 25 *** call this the dynamic bulk etching *** III is for concentrations greater than 25 *** this regime,the bulk etch rate is saturated with respect to the etchant *** classification is discussed and *** role of ethanol in NaOH-based etchants is explored and discussed.A parameter called the “reduced bulk etch rate is defined here,which helps in analyzing the dependence of bulk etching on the amount of ethanol in the *** bulk etch rate shows a natural logarithmic dependence on the density of ethanol in the etchant.
