The XRD and scanning electron microscopic results show that when the volume ratio between H_2SO_4 and H_3PO_4 is 2:1,the oxidation and intercalation effectiveness will be best,and the expanding volume gets to 102 mL·g~(-1).The energy dispersive X-ray spectrum analyses and the Fourier transform infrared spectra indicate there could be H_3PO_4,H_2SO_4,dihydric phosphate and sulphate containing Mn in the layers of EG.

XRD与扫描电子显微镜结果表明，当硫酸与磷酸体积比为2：1时，氧化-插层效果最佳，膨胀体积达到102 mL·g~(-1)。X射线能谱分析与傅立叶变换红外光谱分析显示，EG片层中可能插入了磷酸、硫酸以及Mn的磷酸二氢盐与硫酸盐等物质。

Metal oxide materials are employed as electrodes for Faradaic capacitors, a typical representative of metal oxides is hydrated RuO2, which can yield a capacitance as high as 768 F·g-1 in H2SO4 electrolyte for a single electrode. However, it has a relatively high cost and this will prevent broader commercial applications; Besides, if RuO2 contacts with H2SO4 electrolyte for a long time, it may dissolve at a certain extent; at the same time, H2SO4 electrolyte can erode current collector, which cause entironment pollution.

赝电容器主要是以金属氧化物为电极材料，典型代表为RuO2，无定型RuO2在H2SO4溶液中单电极的比电容高768F·g-1 ；但由于Ru是贵金属、价格昂贵、难于实现商业化，并且RuO2长时间接触硫酸电解液，会出现一定程度的溶解，同时硫酸很容易腐蚀集流体，造成环境污染。

The existence of dextran sulphate to the native ovalbumin leads to decrease about 60％ in fluorescence intensity following high pressure treatment. Complexation of polysaccharide with ovalbumin seems to protect the protein against pressure induced conformational change and aggregation; The presence of τ-carrageenan in glycinin solution is also found to protect the protein against pressure.

经超高压处理后，加入硫酸右旋糖苷的鸡蛋清蛋白溶液中的ANS荧光强度显著降低，降低约60％；这表明，硫酸右旋糖苷的加入可以和鸡蛋清蛋白相互作用，从而在超高压处理中起到稳定蛋白质天然构象的作用；对于大豆豆球蛋白溶液而言，ι-角叉菜胶的加入有维持高压下大豆豆球蛋白构象稳定性的作用。

Circular dichroism spectroscopy measurements also reveal that the ordered structure content of α-helical and β-structure of ovalbumin decrease, and the unfolded random structure is enhanced with increasing pressure; While the existence of dextran sulphate to the native ovalbumin, there are no apparent change on the secondary structure of ovalbumin; It seems same to glycinin.

圆二色性光谱分析表明，经超高压处理后，鸡蛋清蛋白分子中规则的二级结构减少，而部分规则的二级结构和无规卷曲含量增加。加入硫酸右旋糖苷的鸡蛋清蛋白溶液经超高压处理后其二级结构中各部分的含量变化不大：对于大豆豆球蛋白，加入硫酸右旋糖苷后，大豆豆球蛋白分子经超高压处理后其有序结构的减少及无规卷曲的增加都相对减缓。
