    中国大学MOOC: 化学吸附:两者之间有电子转移,形成化学键。不易再生,应用较少。Chemical adsorption: the transfer of electrons between the two to form a chemical bond. Not easy to regenerate, less application.

    Which of the following is false? A: The theories of why immunoregulation beak-down results auto-immunity vary with the disorder. B: Streptococcal antigens cross-react with sarcolemmal heart muscle and the kidney. C: The adsorption of a foreign hapten onto an endogenous molecule doesn't lead to the formation of a hapten-carrier complex. D: SLE is an episode multisystemic disease that usually occurs in young women.

    下列哪些关于吸附作用的说法是正确的? A: 物质从流体相 (气体或液体) 浓缩到固体表面从而达到分离的过程称为吸附作用 (adsorption), 在表面上能发生吸附作用的固体微粒称为吸附剂 (absorbent),而被吸附的物质称为吸附物 (adsorbate) B: 如果在吸附剂和吸附物之间有电子的转移, 发生化学反应而产生化学键, 这种吸附称为化学吸附 C: 当吸附剂和吸附物之间作用力是通过分子间引力 ( 范德华力) 产生的吸附称为物理吸附 D: 物理吸附是可逆的, 可以成单分子层吸附或多分子层吸附, 选择性较差
