group contribution method मीनिंग इन हिंदी

उदाहरण वाक्य

1. This new aqueous system method is based on the group contribution method of Mavrovouniotis.
2. A typical group contribution method using group interaction values is the UNIFAC method which estimates activity coefficients.
3. A group contribution method is used to predict properties of pure components and mixtures by using group or atom properties.
4. The dipole moment of a molecule can also be calculated based on the molecular structure using the concept of group contribution methods.
5. The UNIQUAC model also serves as the basis of the development of the group contribution method UNIFAC, where molecules are subdivided into functional groups.
6. A group contribution method uses the principle that some simple aspects of the structures of chemical components are always the same in many different molecules.
7. Other group contribution methods, especially methods like UNIFAC, which estimate mixture properties like activity coefficients, use both simple additive group parameters and group interaction parameters.
8. If the majority of Group Contribution Methods give results in gas phase, recently, a new such method was created for estimating the standard Gibbs free energy of formation ( ?fG2 ?) and reaction ( ?rG2 ?) in biochemical systems : aqueous solution, temperature of 25 ! and pH = 7 ( biochemical conditions ).
