简介:在这份报纸,我们在Rn上为Hormander鈥檚拉普拉斯算符考虑主要特征值问题,并且我们为如此的主要特征值发现一个比较原则。我们也在整个Rn学习一个相关半线性的亚elliptic方程并且证明在一个合适的条件下面,我们无穷地有这个问题的许多积极答案。关键词主要特征值-Hormander鈥檚拉普拉斯算符-积极答案先生(2000)题目分类35J65-35H20这个工作被中国的钥匙973工程部分地支持

简介:摘要目的探讨婴儿气质类型与个性化发展。方法对290例来我院进行常规儿保的儿童调查分析。结果在290名婴儿中,气质类型分布以易养型和中间偏易养型为主,两个年龄组之间婴儿气质类型分布情况相似,l岁内婴儿两个年龄组中男婴和女婴的气质类型分布是相似的。结论尽管气质类型的分布相对稳定。但也并非一成不变,随年龄增加,易养型婴儿比例降低,启动缓慢型婴儿比例上升。
