查询词典 models

The ratio of final baryon to meson and baryon antibaryon correlation in e +e - annihilation are considered as sensitive observables to test the hadronizition models,because among the results obtainted in different popular hadronizition models,only those from JETSET event generator can fit experimental data by adjusting extra ad hoc parameters.

In this thesis, Water Solubility, 1-Octanol/water Partition Coefficient, molecular Total Surface Area, Aqueous Activity Coefficient, Henry Law's Constant and gas chromatogram relative retention times for biphenyl and its 209 chlorinated congeners were studies with holographic QSAR techniques and highly predictive QSAR models were developed. An internal validation (cross-validation) and external validation were performed to evaluate the predictivity and robustness of the HQSAR models. Based on these highly predictive QSARs, the corresponding data of 5 properties of all these pollutants were presented.
