Because the olefinic hydroxyl groups are linked with olefinic carbon, so it can ionize H〓 ion and present the properties of weak acid, and so the olefinic hydroxyl groups change into the structure of alcoholate in the presence of alkali , but the structure of alcoholate may change into the structure of olefine alcohol again, after the Na〓 ions is removed, or when the pH value of its solution turn into pH. Because the structure of the olefine alcohol is not stable and is easy to isomerizate to become the structure of olefine ketone, so there appear the ca. 1730cm〓 C=O absorption peak in the IR spectra of the products.
明确指出了在C〓、C〓富勒醇中存在烯碳羟基与叔碳羟基等二类羟基,烯碳羟基由于与一个共轭体系相连,从而其羟基可以离解而呈现出弱酸的性质,因而在碱性条件下易形成烯醇钠盐的结构,当除去钠离子后或在酸性溶液中,烯醇钠盐结构转变为烯醇结构,但由于烯醇结构不如烯酮结构稳定,从而形成烯醇结构后,烯醇结构异构化为烯酮结构,因此在其产物的IR谱图上出现1730cm〓附近的C=0吸收信号。

Three are three major actions that Mn effects fracture behavior in the alloy at room temperature, as follow: One is that Mn fines grains, antiphase domains and weakens dislocation clog, which retain formation of cleavage crackle. The second is that Mn decreases APB energy and promotes slop and cross slip, in particular, a large number of cross slip make deformed APBs transform from line type into zigzag type and the APBs interact and cross each other, resulting in propagation of cleavage cracks. The last is that Mn raises the relative proportion of cleavage strength to grain-boundary strength and then restrains formation and propagation of cleavage crack.
Mn对合金室温断裂行为的影响主要反映在三个方面,一是Mn的存在细化晶粒和反相畴,使得位错塞积程度减小,从而阻碍解理裂纹源的生成;二是Mn的存在提高解理强度与晶界强度的相对比值,从而抑制了解理裂纹的形成和扩展;三是Mn降低反相畴界能量、促进超位错的滑移、交滑移,特别是断裂前位错大量的交滑移使形变反相畴由直线型变为折线"Z"字型,反相畴界间的相互作用、相互交错阻碍了解理裂纹的扩展。
