The porine is the polyembryony animal, many obtains the ovocyte from the porine ovary although but the maturity quite to be low; Because the ROSI technology is does not have to grow the mature sole round sperm cell to pour into directly completely in the ovicell nature, jumped over the spermatozoon in to pass through the physiology and the biochemistry, if the ovicell nature mature or the activation degree were insufficient, added the round immature sperm cell maturity quite inferior reason, very possibly Causes the ROSI micro fertilization defeat.
猪是多胎动物,从猪卵巢上获得的卵母细胞数量虽然较多,但成熟度比较低;由于ROSI技术是将没有完全发育成熟的单一圆形精细胞直接注入卵胞质内,跳越了精子在穿过透明带和卵质膜等过程中所发生的生理和生化反应;如果卵胞质成熟或活化程度不够,加之圆形未成熟精细胞成熟度比较差等原因,很可能造成ROSI受精的卵母细胞内部激活因子蓄积减少和生成不足,引起精核解聚困难、精圆核不能形成、第二极体不能排出、卵母细胞孤雌发育率增加等,使ROSI显微受精失败。

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。
