An acyclic edge coloring of a graph G is a proper edge coloring such that there are no bichromatic *** acyclic edge chromatic number of a graph G is the minimum number k such that there exists an acyclic edge coloring using k colors and is denoted by χ' a(G).In this paper we prove that χ ' a(G) ≤(G) + 5 for planar graphs G without adjacent triangles.

In this paper, we study the two-parameter maximum likelihood estimation (MLE)problem for the GE distribution with consideration of interval data. In the presence of interval data, the analytical forms for the restricted MLE of the parameters of GE distribution do not exist. Since interval data is kind of incomplete data, the EM algorithm can be applied to compute the MLEs of the parameters. However the EM algorithm could be less *** improve effectiveness, an equivalent lifetime method is employed. The two methods are discussed via simulation studies.

This study examined the temporal variation of the normalized Difference Vegetation Index （NDVI） and its relationship with climatic factors in the Changbai Mountain Natural Reserve （CMNR） during 2000 - 2009. The results showed as follows. The average NDVI values increased at a rate of 0.0024 year-1. The increase rate differed with vegetation types, such as 0.0034 year-1 for forest and 0.0017 year-1 for tundra. Trend analyses revealed a consistent NDVI increase at the start and end of the growing season but little variation or decrease observed in July during the study period. The NDVI in CMNR showed a stronger correlation with temperature than with precipitation, especially in spring and autumn. A stronger correlation was observed between NDVI and temperature in the tundra zone （2,000-2,600m） than in the coniferous forest （1,100-1,700m） and Korean pine-broadleaved mixed forest （7oo-1,1oom） zones. The results indicate that vegetation at higher elevations is more sensitive to temperature change. NDVI variation had a strong correlation with temperature change （r=0.7311, p〈0.01） but less significant correlation with precipitation change. The result indicates that temperature can serve as a main indicator of vegetation sensitivity in the CMNR.

Measuring the response of terrestrial ecosystems to elevated CO2 concentrations is very important for understanding the effects of global change. In this study,OTC (open top chambers) were used to simulate elevated CO2 concentrations in the Songnen Grass-land. As well,phytoliths in Leymus chinensis were extracted to study the relationships between phytoliths and CO2 concentration. The results show the rondel is abundant in Leymus chinensis,while the trapeziform polylobate is rare. When phytolith production is increased,the rondel phytoliths grow bigger and the proportions of the different phytolith types changes under high CO2 concentration. These types include elongate hollow,acicular hair cell,square and laminate and are only observed in samples grown under high CO2 concentrations. All this evidence demonstrates that phytoliths in Leymus chinensis are sensitive to CO2 concentration,and indicate that phytolith analysis may have potential use in the study of global change,identifying different ecotypes of Leymus chinensis and for the reconstruction of paleoatmospheric CO2 concentrations.

楚国的屈原因为其身处特殊的时代环境,且其个人的际遇遭受到了现实困境,所以屈原的生存境况带有强烈的边缘意识况味,屈赋的创作就与此有着密不可分的联系。而宋代的洪兴祖因为与屈原有着类似的历史境遇,有着相似的人生轨迹,因此他在诠释《楚辞》时,能使解释者的视界与《楚辞》作品内容的视界两者之间达到融合,能深刻体味到《楚辞》作品的真谛,在诠释中体现了自己品读《楚辞》的真知灼见。

英国高等教育在近半个世纪经历了由不收费到收费的变化。在促进高等教育公平、扩大高等教育入学率等背景下,英国高等教育学生资助问题成为一段时期内社会关注的热点问题之一。几经改革,直至2004年《高等教育改革法案》颁布实施后,英国高等教育学生资助制度框架才基本确定,突出体现了多元化、注重差异和以人为本的特点。经过数年的实践验证,目前英国高等教育学生资助制度与运行机制比较科学和顺畅,其成功经验值得我们研究和借鉴。
