In the first part, twelve peptides, including eight conservative amino acid residues in the amino acid sequence of hydrophilic S helix of AOX. were synthesized by solid-phase method. The polypeptide was coupled to a -chymotrypsinogen, and the antibodies were obtained through immunizing rabbit by injecting this complex.

第一部分，我们按照交替氧化酶(Alternative Oxidase，AOX)位于线粒体内膜外侧亲水区S螺旋的氨基酸序列，用固相法合成由12个氨基酸残基组成的多肽，将此多肽与α-牛胰凝乳蛋白酶原A相连，用作半抗原，免疫家兔制备人工合成12肽的抗体。

More levels of nano-SiO〓 lead to larger particle size. An increase in polymerization reaction temperature causes the decrease in coagulum and increase in viscosity and particle size, and the nano-SiO〓 has same effects at certain temperature. When the levels of hydrophilic monomer acrylic acid and hydroxylethyl methacrylate in core composite are increased, the particle size of emulsifier-free emulsion decreases, in spite of the presence of nano-SiO〓.

无皂乳液具有单分散性好、表面洁净、成本低廉、不影响产品性能的特点，首次研究了含或不含纳米粒子的含羟基和羧基的丙烯酸无皂乳液聚合，发现含或不含纳米粒子的无皂乳液聚合后的粒子粒径较大，具有单分散性；较多的纳米粒子导致较大的乳液粒径；反应温度升高，凝聚物含量下降，而乳液粘度和乳胶粒粒径增加，在相同的反应温度下，纳米粒子降低了聚合过程中的凝聚物含量，增加了乳液聚合物的粘度和粒径；不论纳米粒子是否存在，当无皂乳液核组成中亲水单体AA和HEMA用量增加时，乳胶粒粒径均减少。

Each starch reagent has its own mode of action on mineral surface, such as primary starch mainly by hydrogen bond, cationic starch by the co-action of hydrogen bond and electrostatic force (for minerals with negative charge on its surface), while carboxymethyl starch, hydroxamic acid starch and dialdehyde starch principally by chemical force accompanied with hydrogen bond and electrostatic force in part. Such chemical forces ensure the close adsorption of reagent on diaspore surface and enforces the hydrophilic of mineral surface. Also the branched chain enable the starch to cover the collector adsorbed on mineral surface, so as to depress diaspore furthermore.
