查询词典 through bond

Based on the researches of system factors, system characters and the influence of market structure to market behavior, the chapter points out the characteristics and rules of china bond market system variance. On account of the Promoting Effect Government Dominated behavior, compellent system variance runs through the evolution of market structure and act on it. Although derivational system variance also works, it can't be the dominant because of the long variance time and high cost.

根据制度变迁理论研究债券市场结构的制度成因、特点及其对于市场结构和行为的影响，指出中国债券市场制度变迁的特点和规律，由于在中国债券市场的发展过程中，政府主导行为具有明显推动效应，强制性制度变迁始终贯穿于市场结构演变的过程中，并对其形成重要作用；诱致性制度变迁虽然也穿插其中，但由于其变迁时间长、成本高等特点，无法形成主导力量。

Multi-bioinsecticidal-toxin BtA is a bioconjugation product with multiple acting-sites, formed by biochemical bond-linking reaction between two biotoxins, protoxin of Bacillus thuringiensis and Abamectin, through the amino and carboxyl conjugator EDC.
