(1) The implementation problem that social fair covalence is worth decided the outlook that socialistic commodity produces and destiny on certain level.

(2) The results show that the covalence bond-net is much stronger than in GPB zone and the whole covalence energy of S" phase is much strong."

(3) On the other hand, if we have a perfect covalence bond, we have identical equal sharing.

(4) The results show that the hydrogen of C—H bond on ACFs were substituted by fluorine at different condition. The C—F covalence bond was built at molecular level.

(5) Transition metal nitrides belong to a class of interstitial compounds, have the properties of covalence compound, ion crystal and transitional metals.

(6) Influence factor and control measure on the preparation of molecular template polymer by non- covalence method were reviewed concisely.

(7) C_(60) is one kind of fullerene with high conjugated cage-types structure. Its covalence between two hexagons has high reactivity, which behaves as addition reaction of double bond.

(8) Using the activated fibroin as carrier, the papain was immobilized using covalence - crosslinking method.

(9) The results show that sericin could be directly coated on the oxidized cotton fiber without any other reagent and form a covalence bond between amido group and aldehyde group .
