Nitre rate is very low.These conditions are to trap the problem that must take into before oxynitride, therefore traditional industrial method of denitration is
The demand of environmental development can not be met, the oxynitride capture method of efficient economizing is the inexorable trend of environmental development.
1991, NO caused the concern of research worker as new messenger substance between a kind of neurocyte, to NO
Research be deep into central nervous system and peripheral nervous system from the beginning of blood vessel, in succession, NO is with flanking cell as target
And guanylate cyclase is activated, so that second message,second messenger's material cGMP is generated increase and may activate then and depend on the albumen of cGMP to swash
Enzyme, produces specific physiological effect.Research shows, NO is intercellular gatekeeper, will have very big sending out in field of medicaments
Exhibition space.Secondly, Fei Rui admires rad (Ferid Murad) because finding that " nitric oxide plays signal in cardiovascular system and divides
Son is acted on " and obtain the Nobel prize's soul of 1998.It can thus be seen that design synthesizing efficient for catching
The material of collection NO is extremely urgent.
