We establish some connections between geometric properties, properties in analysis and analytic properties of the inducing map ψ and operatortheoretic properties of composition operator C〓: f〓fοψ on various analytic function spaces mentioned above, include the boundedness, compactness, weak compactness, collective compactness and the Schatten class operator ideal, etc. Our results extend some previous results, for instance, the Shapiro's Nevanlinna counting function condition and the MacCluer's Carleson measure condition for the compactness of C〓 on Hardy space.

In this paper,Laterite soil adjacent to some stake of the highway in Chenzhou, Hunan section from Xiamen to Chengdu was used to investigate the deformation characteristics and protection methods of the Laterite soil subgrade under the influence of environment factors.Properties like water-holding capacity,capillary rise, coupled heat-moisture transfer and wetting deformation of samples under different compactness were studied through a series of laboratory tests.In addition,by using meteorological data of two consecutive years in Chenzhou,coupled process of moisture transfer and subgrade deformation was stimulated under the impacts of groundwater and the atmosphere.Specific work done in this paper is as follows:(1) Samples under different compactness were subjected to a series of conventional laboratory tests,such as permeability,consolidation,contraction,shear test and etc.

compactness：紧致性

空间上不同的拓朴结构,除了会影响空间的紧致性(compactness)、连通性 (connectedness) 之外,对於在该空间上运作的算子之行为与特性,也扮演著举足轻重的角色.

compactness：紧密度

对比分析表2和表3中的实验数据,可以清楚地看到纵横比(Aspect Ratio)、紧密度(Compactness)和形状因子(Shape Factor)3个参数定量表征γ′相粒子形貌的有效性.

compactness：紧性

例如,雅克.拉康(Jacques Lacan)的名字被美国和英国大学的许多人文院系的人们所崇敬,无疑,这部分地是因为他假装对数学有着深刻的理解:尽管拉康引用了一些数学上紧性(compactness)理论的关键词,他把这些词随意的混合在一起,

compactness：紧凑度

Botafogo(1992)等人根据图论提出了一些用来描述层次性超文本的大小和复杂度等方面特性的 童化指标,如紧凑度(compactness)、层(stratum)等. 这些指标对改善超文本的编写有指导作用. Blustein (1997 )等在前人研究基础上提出了一种评价超文本链接质盘的新方法,

compactness theorem：紧性定理
