Results The result showed that 0.7% and 1% sodium pentobarbital anesthesia duration was too short, 1.5% pentobarbital sodium easily made animal deaths, and 10% chloral hydrate used for anesthesia in mice was appropriate. And the glass cannula was more suitable than adhesive bandages for enswathement.

结果 0.7%和1%戊巴比妥钠麻醉持续时间过短，1.5%戊巴比妥钠和10%水合氯醛能维持足够手术操作所需的时间，但1.5%戊巴比妥钠易导致动物死亡，故采用10%水合氯醛麻醉小鼠较合适；玻璃套管法包扎的效果较创可贴法为好且更简便。

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。

The mechanism of carbonization process of aluminate solution was analyzed thermodynamically. The results show that the internal reason of precipitation of Al3 in the process is its spontaneous nucleation caused by supersaturation of aluminate solution. The behaviors of SiO2 in the process are in accordance with that from published experiment, which implies that the content of product SiO2 from carbonization depends on its solubility but is not the result of absorption. The thermodynamic calculation for forming Na2O·Al2O3·2CO2· n H2O was achieved.

摘 要：为对高浓度铝酸钠溶液碳酸化分解过程中产品杂质含量的控制提供理论依据，分析了铝酸钠溶液碳酸化分解过程的热力学，认为该过程中Al3析出的真正机理是过饱和铝酸钠溶液的自发结晶；而基于分解过程中平衡浓度的热力学计算表明，在碳酸化分解过程中SiO2的变化规律与公认的三段变化规律一致，说明该过程产品中SiO2的含量取决于它在溶液中的平衡浓度，而非吸附所致；同时还分析了丝钠铝石的形成热力学。

Antinociception and VGSC-modulation of BmK IT2 and BmK AS—1. The results from nociceptive flexion reflex and plantar radiation heat showed: BmK IT2 (a depressant insect-selective neurotoixn) and BmK AS-1 (a new-type β-1ike neurotoxin) have significant antinociceptive effects on rat peripheral nerve system. The antinociceptive effects of BmK IT2 on the carrageenan-inflamed rats were significantly stronger than those on the normal rats. Whole-cell patch-clamping showed: Both TTX-S and TTX-R Na〓 currents induced from rat DRG neurons were significantly inhibited by BmK IT2 and BmK AS—1, and BmK IT2 was more sensitive to TTX-R than TTX-S component. All the results suggested: the peripheral antinociception of BmK IT2 and BmK AS—1 might be attributed to the inhibitory effects of them on the TTX-S and TTX-R Na〓 channel located on the peripheral ends of rat DRG neurons with small diameter.
