solute concentration difference的用法和样例：
- If the environmental relative humidity is lower, the drop will undergo evaporation and solute concentration will rise.
- The enthalpy of mixing increased with the increase of temperature and solute concentration.
- The absortion rate was controlled by adjusting the solute concentration of the inlet gas.
- The membrane potential of shaly sand was influenced by the cation exchange capacity, hydrocarbon saturation and concentration difference of the contacted solutions.
- This paper describes the principle, method, precision, range and prospect of application of nuclear track membrane to determination of solute concentration.
