Discussion on the mechanism of the calcium absorption in the human body
《Chinese Science Bulletin》2001年第16期1403-1408,共6页ZHANG Jingkun ZHANG Zemin YU Ao 
The present article discusses a new mechanism of calcium absorption in the human body. The mechanism is revealed as follows. First, after food is digested in the stomach, calcium ions (Ca2+) are released. The small in...

A NOVEL HIGH ACTIVE IRON CATALYST Fe(naph)_2-AI(i-Bu)_3-HALIDES FOR POLYMERIZATION OF BUTADIENE
《Chinese Science Bulletin》1988年第12期988-990,共3页沈琪 郭小光 许肖龙 刘国智 
Project supported by the National Natural Science Foundation of China
In recent years some kinds of iron catalysts for the polymerization of diolefins have been reported. In all of the known iron catalysts, a donor, such as P-com- pound, S-compound, N-compound or O-compound, has to be u...

INFRARED SPECTRA OF N-ACETYLACETOAMIDES AND THEIR Cu^(++) COMPLEXES
《Chinese Science Bulletin》1987年第6期424-425,共2页杨新潮 冯子刚 
The infrared spectra of 16 N-acetylacetoamides（contracted as RA in the following） and their 6 Cu++ complexes have been investigated. Their infrared characteristic bands have been primarily assigned on the basis of o...
