Investigate and Support Kinetics Unsympifiable by Sympy for Checks 1003 and 1004

[longxf21]

Identify and address the issue where certain kinetics expressions cannot be processed (sympified) by Sympy, resulting in their lack of support for checks 1003 and 1004. This problem suggests there are kinetics expressions that the current implementation does not accommodate, likely due to their complexity, specific functions, or symbols not recognized by Sympy.
