Through the building of newgeometric relation, the expression of the height of compressive area in the corrodedbeam with rectangular section has been deduced, and the formula with corrosion rateas the main variable for the anti-bending capacity of the corroded concrete beam hasbeen suggested and verified by experiment.; 3 The influence of steel bar corrosion and the concrete regression to the flexureductility coefficient of the corroded structure component has been analyzed. Based onthe relation of steel bar and concrete at yield and ultimate, the expression for theflexure at yield and ultimate of corroded reinforced concrete beam, and the model forthe calculation of the flexure ductility has been built.

A new theoretical model, the 2CLJDQP potential function, was developed for linear molecules, which takes into account dipole, quadrupole and induction effects as well as the rotation of the dipole out of the molecular axis. The energy parameters were optimized for various types of fluids. With the modified mixing rules, the potential parameters obtained from homonuclear molecules can be used to calculate the second virial coefficients of heteronuclear molecules. The model was also successfully extended to triatomic molecules. Analysis of the contributions to the second virial coefficients of long-range interactions shows that the molecular interactions introduced in the present model, such as, the induction effects, cannot be neglected.
