资 源 简 介
pp contains an embedded version of PHREEQC. pp sits on top of PHREEQC and makes it relatively straightforward to do repetitive PHREEQC calculations, the type of calculations that are often needed to make a plot. pp uses tags placed within the PHREEQC input file to identify places where substitutions are to be made and has several looping mechanisms to control the values substituted. It also contains software for generating Postscript plot files. If Ghostscript and GSview are installed then automatic conversion to pdf, png, jpg, ai and epsi formats is possible, as well as viewing of the natively-generated ps files. In addition to normal PHREEQC-type calculations, pp can be used to generate predominance diagrams and to fit observations to PHREEQC models by nonlinear least squares.
