上面的研究发现膜稳定剂在体内体外均抑制了内质网应激，并改善了心脏功能，而膜稳定作用实际上是维持细胞钠离子稳态的结果，为了研究内质网应激反应与钠离子活动的关系，我们用一种钠通道激活剂藜芦定刺激H9c2(2-1)细胞，30分钟时GRP78表达增加；24小时时PERK磷酸化和CHOP蛋白表达显著增加，说明钠离子通道过度激活诱发了内质网应激反应。

The dust was first mixed with NaBH4 powder to adjust the H/Cl ratio. Then, the sample was roasted at low temperature to promote the efficiency of dehalogenation/hydrogenation reaction. By way of Cl- titration, it was found that the roasting temperature (300℃~500℃), roasting time (5 to 25 minutes) and H/Cl ratio (6.0 to 20.0) would change the dissolution of Cl- from 0.0% to 17.5%. After caustic roasting and leaching of the dust, the zinc (17.4 g/l) and lead (1.6 g/l) recovery ratio were found to be 82.7% and 61.8% respectively.

利用NaBH4在低温可促进氯化冶金反应的进行，经由氯离子浓度滴定，发现随著焙烧时间、温度及H/Cl比值之调整，氯离子之溶出量变化亦相对改变，此结果说明在使用NaBH4调配H/Cl比值由6.0~20.0的变化下，烟尘中的氯成分在低温(300℃~500℃)焙烧5~20分钟，可与金属氧化物发生氯化反应，氯离子溶出量显示有0~17.5%不等之变化量。

It is the fluorosilicic ion that exsits in the slurry and plays an important role in flotation, fluorosilicic ion not only reacted with Fe〓 on the surface of aegirine to form ionic compound, but also formed stable Si-F bond in Si-O etching reaction. Only ionic compound was obtained when it was attached to hematite surface according to the theories of coordination chemistry, Compared with SiF〓, Fatty acid ion preferentially acts with Fe〓 on the minerals surface, therefore, SiF〓 Can't obstruct the adsorption of collector on the surface of hematite completly, but can reduce the flotation recovery of aegirine selectively.

运用FTIR、XPS等测试方法仔细研究了氟硅酸盐抑制剂对含铁硅酸盐钠辉石的选择性抑制作用机理，氟硅酸盐在弱酸性条件下对赤铁矿浮选的抑制作用很微弱，而对含铁硅酸盐钠辉石强烈抑制，从而扩大了两者之间的浮选差异；SiF〓是矿浆中起抑制作用的主要成分，SiF〓不仅与钠辉石表面的Fe〓形成离子型配合物，而且还与Si-O键形成稳定的Si-F共价键，而与赤铁矿表面只能形成离子型配合物，根据晶体配位场理论，与SiF〓相比较羧酸根离子将优先与矿物表面Fe〓发生配位作用，因此SiF〓的存在并不能完全阻碍捕收剂在赤铁矿表面的吸附作用，却能够选择性地抑制钠辉石的上浮。
