1. The results showed that RSPP-2 is a good deoxidant and can scavenge reactive oxygen species and inhibit lipoxygenase in some modified chemical systems.

2. To determine the content of deoxidant timely and precisely is urgently need in the operation of boilers.

3. Silicon carbon ball deoxidant is produced by selecting raw materials and processing of brokening, screening, mixing, pressing ball and drying.

4. Packing with material of low venting quality and adding deoxidant were applied to inhibIt'seedstorage.

5. The process of producing low-carbon aluminium killed steel using new deoxidant in the steelmaking plant of Baotou Iron and Steel(Group) Co was introduced.

6. The results of the experiments show that the material has strong selecting adsorption character for oxygen and the respiration process can repeat well. YBCO may be used as deoxidant sieve sorbent.
