弹性血管二维分岔模型的有限元分析及数值模拟

采用任意拉格朗日—欧拉方法(ALE),对二维弹性分岔血管中的速度场和压力场进行了分析.通过弹性分岔血管中与刚性分岔血管中速度场和压力场的比较,结果表明:在刚性分岔血管中,其分岔口的速度和压力都比较大;而在弹性分岔血管中,由于管壁的弹性影响,其分岔口的速度和压力都比刚性分岔血管的小,更加接近于正常的生理状况.所以,弹性血管比刚性血管的模拟效果好,它既能够方便于我们了解心血管疾病的机理,尽早地预防心血管疾病,又能够为临床实验工作提供一种好的理论分析方法.

This is Huey P. Long talking

Few Americans are familiar with the structure and myriad junctions of the EBU; one of the most important organizations concerned with the broadcasting in the world. Mr. Barber, a doctoral candidate at Northwestern University, is currently in Europe as the guest of the EBU while on a special data‐collecting grant from The Danforth Foundation.     

Advertising images among Hong Kong Chinese: Use of individual modernity and western orientation clusters in determining market segmentation∗

Advertising is a highly visible force in Hong Kong society. Within this diverse environment, media organizations and marketers attempt to define target markets (market segmentation) composed of persons who are most likely to be influenced by their marketing and advertising efforts. This research, based on a 1,019 sample face‐to‐face intercept survey, segments the market based on measures of self‐ascribed individual modernity and individual traditionalism and Chinese and Western value orientation. The scales are statistically analysed by cluster analysis, to place each respondent into clusters. The segmentation scheme viability is analysed in relation to media consumption and attitudes about specific advertising issues in six areas: 1. consumer benefits and economic force; 2. credibility; 3. entertainment value; 4. social force; 5. manipulation and motivation; and 6. repetition. The segmentation of individual modernity/traditionalism and Chinese/Western orientation provides greater differentiation than age, gender, income, education or place of residence.     

An Experimental Study of the Effect of Educational Guidance on a Selected Group of High School Sophomores

The question of an interaction over time between ability grouping and personality variables was the focus of the present study which examined pertinent data from 260 female high school students. Two standardized personality instruments, in addition to several scales designed by the E’s, were administered to students of the upper and lower ability tracks in a Catholic high school, grades 9 and 12. Ss in the lower track were found to have a lower need for achievement, a higher need to avoid failure, and a higher average score of test anxiety than Ss in the upper track. The effects of ability grouping did interact with grade level for a correlate of personality, level of aspiration. Relative to Ss in the upper track, the lower track Ss experienced a reduction in level of aspiration over time. Both future directions of associated research and educational practices were discussed within the context of the present findings.
