Through the experiments on hydration of AH in the following sulphate(Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4), dissoluble sulfate hydrate origining from hydration process of AH affects it's hydrous rate, hydrous rate of AH does not connect with Z/R of cation in stimulation, theory that Z/R affect hydrous rate of AH does not exist. Third, hydration of AH in dissoluble sulfate complies with dissolve-nucleate -grow theory, concentration of Ca~2+ from dissolving of CaSO_4 is higher than one of CaSO_4·2H_2O, calcium sulphate dihydrite gets a motivity of crystallization. dissoluble sulfate takes the following function: double-salt or dissoluble sulfate hydrate from hydration of AH in it becomes heterogeneous particle and a kind of nucleation catalyzer, and reduces surface barrier when DH becomes crystal because the crystal of DH precedently appears in uneven place. Results indicate hydration of AH does not conform with double-salt theory, but it conform with this mechanism: dissolve-nucleate-grow, formation of DH is an uneven nucleation and crystalizaion process.
通过对CaSO_4在Na_2SO_4 、K_2SO_4 、Rb_2SO_4 、Cs_2SO_4 、(NH_4)_2SO_4溶液中水化过程,以及CaSO_4·2H_2O、CaSO_4与以上硫酸盐反应速度、产物的研究,说明复盐理论不正确;CaSO_4在(Li_2SO_4、MgSO_4 、 Al_2(SO_4)_3 、MnSO_4 、CuSO_4 、CoSO_4 、CdSO_4 、ZnSO_4 、NiSO_4 、FeSO_4)溶液中水化,水化过程中硫酸盐水合物的析晶影响着无水硫酸钙水化,与激发剂阳离子Z/R值大小无关,阳离子的Z/R参数影响水化率的规律并不存在; 3、无水硫酸钙在可溶性硫酸盐中的水化按照溶解-成核-生长理论进行,CaSO_4达到溶解平衡时Ca~2+的浓度大于CaSO_4·2H_2O溶解平衡的Ca~2+的浓度,CaSO_4·2H_2O获得结晶的驱动力,可溶性硫酸盐起到形成晶核的作用:水化过程与CaSO_4生成复盐或析出水合物所形成的细小物相,作为异质微粒使母相中存在不均匀性,这些不均匀性有效地降低成核时的表面能位垒,使CaSO_4·2H_2O晶核优先地在这些具不均匀性的地方形成,因此这些物质起成核催化剂作用。

The effects of strain rate on plastic formation and dynamic recrystallization of 7050 aluminum alloy were discussed. The results show that the deformation of the specimen is inhomogeneous, and the effective strain in the center of the specimen is maximum. The deformation inhomogeneity increases with the increase of strain rate. The effective stress of specimen is inhomogeneous. As the strain rate increases, the minimum stress value moves from the drum-shaped region to the heart of specimen. The standard deviation of dynamic recrystallization grain size decreases with the increase of strain rate.
