1·Adsorption model, the thermodynamics parameters, sticking probability and activation energy of fluor hydronium on modified coke powders were investigated.

考察了改性焦粉对氟离子吸附模型、热力学参数、粘附几率和活化能，初步探讨了吸附机理。

2·The probability of packer sticking is increased because of the casing deformation and crustation in casing failure well.

在套损井中，由于套管变形、结垢等因素，进一步加大了封隔器卡钻的可能性。
