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。

It proves the singular transport operator generates a strongly continuous C_0 semigroup V(t0)and the weak compactness properties of the second-order remained term of the Dyson-Phillips expansion for the C_0 semigroup V(t0)in L1 space,and to obtain the spectrum of the singular transport operator only consist of,at most,finitely many isolate eigenvalues which have a finite algebraic multiplicity in trip Γ.

证明了这类方程相应的奇异迁移算子产生C0半群和该半群的Dyson-Phillips展开式的二阶余项是弱紧的，从而得到了该迁移算子的谱在区域Γ中仅由至多有限个具有限代数重数的离散本征值组成等结果。上饶师院数学与计算机系江西上饶334001；南昌大学数学系江西南昌330047袁邓彬

In this paper, a new real AdaBoost algorithm based on multithreshold method was developed. Through the selection method of multioptimization threshold and combining the strategy of weak classifier threshold selection in discrete AdaBoost algorithm, the rational division of sample space was implemented.
