At the same weather and space-time, CO 2 content in rainy season was higher than that of CO 2 in dry season at both day and night.

The local ordered CoPt〓 Ll〓 phase with good FCC (111) crystalline orientation, which exists at the interfaces of multilayers and in alloy films, was considered to contribute to the PMA in Co/Pt multilayer and Co-Pt alloy films. But the appearance of large amount of ordered CoPt〓 Ll〓 phase or completely disordered Co-Pt phase will result in the decrease in PMA.

Co/Pt多层膜界面处或Co-Pt合金膜中具有FCC（111）织构特征的局部有序CoPt〓 Ll〓合金相的形成被认为可能会对多层膜和合金膜中的垂直磁各向异性作出贡献，但大量CoPt〓 Ll〓有序相或大量完全无序Co-Pt合金相的生成都会导致垂直各向异性的下降。

NO elimination reactions are much complicated in the system of NO-CO-CO2-N2 with the existence of metallic oxides. Homogeneous reaction between NO and CO, reduction of NO by the lower valued metallic oxides, direct decomposition of NO as a catalytic reaction and catalytic reaction of NO/CO may all contribute in NO elimination.

Aortic NOS/NO and HO/CO system are impaired significantly in atherosclerotic rabbits induced by high cholesterol diet. Decreases of endogenous NO and CO production are associated with atherosclerotic progression. Both L-arginine and heme-L-lysinate inhibit atherosclerotic progression by increasing NO or CO production.

高胆固醇饮食诱导的AS显著损害了主动脉NOS/NO及HO/CO系统，内源性NO及CO生成量减少与AS的发生发展密切相关。L-精氨酸及血红素-L-赖氨酸盐分别通过增加主动脉NO及CO生成量而抑制AS进展。

It is found that the nature of the interaction between CO and Pd(110) surface by population analysis and DOS analysis what the 5σ orbital of CO and the d orbital of metal formed electron donation; and the 2π* orbital of CO and 4s and 3d orbital of metal formed electron back- donation.

When SiO〓-NH〓-Rh-Co complex was used to catalyze the hydroformylation of methyl methacrylate, an optimal conversion of 93.4% and optimal selectivity of 84.4% for the normal aldehyde were both obtained at Rh/Co ratio of 2/1, which were both higher than that catalyzed by SiO〓-SiNH〓-Rh and SiO〓-Si-NH〓-Co momometallic catalysts. Clearly a synergistic action between Rh and Co atoms presented in the complex.
