The process of our study links some of the most basic questions about C〓 with beautiful classical results from analyticfunction theory. For instance, it is essential Littlewood subordination theorem that assures that composition operators act boundedly on many analytic function spaces. And there are close connections between the compactness of C〓 and the existence of angular derivatives of ψ at points of 〓D. It involves the classical Julia-Careatheodory theorem, Denjoy-Wolff theorem and Nevanlinna counting functions and so on. It makes many old theorems in analytic-function theory getting some new meanings, and bestows upon functional analysis an interesting class of linear operators. This thesis consists of six chapters as follows: Chapter 1 is a preparatory in nature.

After hears the yellow Jinlong commander in chief's order, already succeeded the hook to live this planetoid the starships, after passed through the very short time, had achieved with the planetoid the similar speed, likely the human rode in the acceleration the airship to be same, starts the anchor chain which back and forth vibrated this time already to pull taut, and started to maintain stably, all starship pilot, already not in the worry planetoid surface more than 1200 degrees high temperatures, the thick fog group which as well as raided intermittently, after received the order then the rapid start automatic hinge machine, to this planetoid superficial fast advancement, in order to set aside the enough debarkation space for the second interspace group,This time by far looks, the entire starry sky scene, looks like a big spider to lead only to creep along innumerably small spider such, has filled the mysterious visual effect, lets the human feel incomparably shocks!
