A one-pot three-component method for the synthesis of 2-methyl-3-aminobenzofurans using calcium carbide as a concise solid al-kyne source,and salicylaldehydes and secondary amines as starting materials is described.This protocol has salient feature of the use of inexpensive,abundant and easy-to-handle alkyne source,avoiding the use of inflammable and explosive acetylene gas as an origi-nal alkyne source.In addition,step economy,satisfactory yield,and simple work-up procedure are also advantages of this route.

针对凸度量空间中的抽象凸结构,提出了3种新广义W-凸函数,以及利用中点W-凸性研究了凸度量空间中广义凸性的方法.首先,将线性空间中基于标准凸结构的3种广义凸函数概念引入了凸度量空间,定义了3种新广义W-凸函数;其次,在适当条件下,证明了中间点W-凸函数是中点W-凸函数,也是[0,1] ∩Q-W-凸函数,进而获得了稠密性定理,并讨论了稠密性定理在极小化问题和多目标规划问题中的应用;最后,在中点W-凸性以及上半连续性或下半连续性或W-拟凸性或W-严格拟凸性或W-半严格拟凸性等条件下,建立了W-凸函数的一些判别
随机微分方程是概率论与确定性微分方程相结合的产物,与确定性微分方程精确解的求解相比,随机微分方程精确解的求解是十分困难的.于是针对近几十年来兴起的热门边缘学科——随机微分方程的求解方法,提出了求随机微分方程数值解的方法应用及比较.讨论了求解随机微分方程数值解的方法,即Euler-Maruyama方法、Milstein方法和Runge-Kutta方法,并应用几个实例比较了在不同布朗运动影响下随机微分方程的精确解与确定性微分方程的精确解的不同之处,还比较了不同数值方法的求解结果及数值解与精确解的误差;编程图示

针对现有的房地产估值模型中不包含空间自相关性以及非线性影响因素的问题,提出了可以灵活解释变量意义的部分线性空间自回归模型来拟合房地产估值数据;对于部分线性空间自回归模型的估计问题,利用局部多项式方法与拟极大似然估计法相结合的两步估计过程得到参数部分的估计;房地产估值数据的拟合结果表明:房地产估值数据确实存在空间相关性,房屋到最近的捷运站的距离与房价呈负相关关系,而步行生活圈中便利店的数量与房价呈正相关关系,这与现实意义上的解释是相通的,另外房屋年龄与房价之间的非线性关系也被体现出来;部分线性空间自回归模型
