Based on the construction of urban landscape forest and application of stereoscopic landscapes in CAST(Chongqing Academy of Science and Technology),Ginkgo biloba L.,Ficus virens Ait.var.sublanceolata(Miq.) Corner,Cinnamomum camphora and Magnolia liliflora were selected as major tree species and stereoscopic landscaping plants for the "CAST Stereoscopic Landscape Demonstration Project".Through investigating landscapes and functions of all these species in the urban landscaping,the authors anaiyzed stereoscopic plant landscapes of the CAST project,summarized application of these tree species in the stereoscopic landscapes,and concluded representativeness of these species in the CAST project.Finally,deficiencies of tree species in the CAST project,their maintenance and management were analyzed to ensure the reasonable application of tree species,and to provide references for the construction of urban landscape forest and popularization of stereoscopic landscapes. 展开更多

In this papert the theory of major efficiency for multiobjective programmingis established.The major-efficient solutions and weakly major-efficient solutions of multiobjective programming given here are Pareto efficient solutions of the same multiobjectiveprogramming problem, but the converse is not true. In a ceratin sense , these solutionsare in fact better than any other Pareto efficient solutions. Some basic theorems whichcharacterize major-efficient solutions and weakly major-efficient solutions of multiobjective programming are stated and proved. Furthermore,the existence and some geometricproperties of these solutions are studied. 展开更多

During the active process of reading, strategies involved will affect the process of reading comprehension, and the reader should intentionally regulate and control the reading process and adopt appropriate strategies to solve the problems during it. The purpose of this paper is to determine the use of metacognitive strategies in reading by the PE & Art majors through questionnaire. According to the result of the questionnaire, the PE & Art majors do use some metacognitive strategies in their reading, while nearly half of them do not often use metacognitive strategies in their reading. For this phenomenon, the author gives some constructive suggestions for the English majors about how to apply the metacognitive strategies in their reading: 1) preparing and planning in pre-reading; 2) monitoring and self-questioning in while-reading; 3) evaluating and adjusting in post-reading. 展开更多
