1.The 3D images from 3D CT reconstruction can show all facial bones and their connections, confirm the borderline and size of the diseased tissues and their relation to the adjacent tissues. With the aid of 3D images, the site and scope of the tissue defect and mass focus can be exactly estimated before operation.
3.Business scope: expo pictorial, real estate scheming, CIS, 2-D design, packaging design, outdoor ad.
5.And it also points out the formula of average intercept D of Auster grain and Austerization temperature T in test steel and further finds that X70 strength becomes higher and roughness becomes lower with the higher heat temperature,and within the scope of 850～1 050 ℃,the march of strength and roughness is better.
6.Plant endemism is the key problem in floristic study.Analysis of endemism in a flora has significant implications in demonstrating floristic richness and diversity,the relationship between plants and their environment,and also in conserving biodiversity of the flora.In view of the situation that most of the past studies on endemism were qualitative,this study is the first tentative approach to the introduction of quantitative indices to the analysis of floristic endemism,with an purpose to push the study of endemism from qualitative to quantitative.Four quantitative indices are introduced,i.e. level of endemism(L),coefficient of endemism(C),degree of endemism(D) and general index of endemism(A).Mathematical formulae have been given to each of the above indices and explanations for them have been presented,and the scope of their use in floristic studies has been delimited and exemplified in this paper.The result shows that they are of good applicability.The proposed indices embody full information of plant systematics and plant geography.With the aid of qualitative analysis,the application of the proposed indices will improve the comparability and precision of endemism study in floristics.
7.Through the analysis of24 major American periodicals on library science published between 1972 and 1996,this paper,from the angles of the quantifies of both the citations and the cited,draws the conclusion that library science apparently proves to be mainly a technical and practical academic subject that has a relativdy limited scope d research,an imperfect theoretical system,and a relatively poor application to other subjcets.
