In this work, we study the Cauchy problem for the radially symmetric spatially homogeneous Boltzmann equation with Debye-Yukawa potential. We prove that this Cauchy problem enjoys the same smoothing effect as the Cauchy problem defined by the evolution equation associated to a fractional logarithmic harmonic oscillator. To be specific, we can prove the solution of the Cauchy problem belongs to Shubin spaces.

Molecular mechanics and quantum mechanics simulations, as molecular simulation methods, were performed to investigate the effects of different surfaces, the promoter Co/Ni, the active phase of MoS2 or WS2, the content of Si and other factors on the order of interaction between the MoS2 （WS2） single slab and the support surface. The influence of Si content was studied by molecular mechanics, and an advantageous Si content was found. Various surfaces, promoters and active phases also played an important role in the interaction between the support surfaces and active phases, and some significant trends were found out. Quantum mechanics simulation was performed to study the possible effect of electrostatic interaction between the support and the active phase, upon which the calculations suggested that the existence of a favorable Si content was possible. The electronic effects of Co/Ni promoter and the intensity of Co/Mo/Ni/W/li/AI/Si species bonded to the alumina support were also investigated by quantum mechanics, and it was found that the different electronic effects of Co and Ni might bring forth some obvious influences on the interaction between the support and the active phase. And the results of comparing the intensity of Co/Mo/Ni/W/li/AI/Si species bonded to the support can also explain the different interaction intensity in various catalyst systems.

由于形象思维方式是人类的一种本质思维方式,人类通过各种感官来认知事物的规律性,进而提取出具有代表性的特征,因此通过形象思维的方法来提取事物的本质特征符合人类认知事物的规律.针对人脸识别中特征提取问题,该算法以形象认知规律与无监督判别投影为理论基础,提出了一种仿生不相关空间局部保持鉴别分析(biomimetic uncorrelated locality preserving discriminant analysis,BULPDA)算法.算法首先根据人类形象认知的特性构建了一种新的相似系数表示方法;然后结合不相关空间概念,确保矢量空间具有不相关性;最后给出了基于奇异值分解的矢量空间求解方法,形成了一种特征提取新思路.在标准数据库上的实验结果表明,新算法优于传统的特征提取方法和其他改进的局部保持投影方法.

基于玉米油分的花粉直感效应,采用核磁共振鉴别单倍体,快速、准确、低成本地确定单倍体与二倍体之间的含油率阈值,是实现大批量自动鉴别的前提和关键。提出一种基于最小平方误差的单倍体和二倍体分类方法,通过少量籽粒确定含油率阈值的研究,对单倍体和二倍体进行识别。以10个玉米组合为研究对象,利用核磁共振分析仪测定各组合一定数量单倍体和二倍体籽粒的含油率,依据最小平方误差方法确定各组合油分阈值,并通过逐级递增训练集样本数量的方法,确定油分阈值所需训练集规模,获得含油率阈值,能够满足单倍体正确识别率及对二倍体正确拒识率的均值达到90%以上的要求,为核磁共振全自动单倍体鉴别系统的后期大规模分类提供参数指导,提高分选效率。同时因单倍体生产效率低,运用最小平方误差的方法,通过少量的单倍体及二倍体籽粒来构建油分鉴别单倍体模型,以较小的投入获得更优的分类效果在玉米单倍体自动化分选中具有非常重要的现实意义,将该分类方法应用到全自动核磁分选单倍体系统中,可以达到较好的效果,为加快单倍体工程化育种提供保障。
