Firstly, the reaction thermodynamics was analyzed. Then, the reaction mechanism was studied, and the results are as following:① Ca moves to the surface of Dy〓O〓 by vapor phase;② Dy〓O〓 reduced to Dy by Ca is fast;③ Dy moves to the Fe surface mainly by vapor and various Dy-Fe alloys are produced gradually;④ The forming process of DyFe〓 may be described by Contracting Core Model;⑤ The rate-controlling step of the reaction is the Dy diffusing toward contracted and nonreaction nuclear center Fe.

首先考察反应的热力学可能性；其次探讨反应机理；通过实验确定：①Ca主要以气态形式迁移到Dy〓O〓表面参与反应；②Dy〓O〓被Ca还原为Dy的速度很快；③Dy主要以气态形式迁移到Fe表面逐级生成Dy-Fe合金；④DyFe〓的形成过程可以应用收缩核模型来描述；⑤Dy通过DyFe〓产物层向缩小的未反应核中心Fe的扩散是反应的控速步骤，通过动力学计算确定：还原扩散反应的表观活化能E〓=45kJ/mol。

When cellular Ca~(2+) concentration increased, Ca~(2+)与can combinewith calmodin create compound, the latter arose VSMC shrinking through phosphated, and can accelerate express of many cancer gene, such as c-fos、c-myc、c-myb, consequently bring the multiplication and plumped of VSMC.
