Implications of a new, biostratigraphically well-controlled, radio-isotopic age for the lower Telychian Stage of the Llandovery Series （Lower Silurian, Sweden）

引用

Episodes 2008年第3期31卷 309-314页

作者： Stig m. Bergstrom Funda Ozlem Toprak Warren D. Huff Roland mundil School of Earth Sciences Division of Geological Sciences The Ohio State University 155 S. Oval Mall Columbus Ohio 43210 USA. Department of Geoiogy University of Cincinnati Cincinnati Ohio 45221 USA Berkeley Geochronology Center 2455 Ridge Road Berkeley California 94709 USA.

Radio-isotopic analysis of single zircons from two early Telychian K-bentonites, one of which is among the most widespread Lower Paleozoic volcanic ash falls in north- ern Europe, yields overlapping weighted mean 206pb/238U ages of 438. 7± 1.0 ma and 437.8 ± 0.5 ma, respectively. The former age is from zircons of the Osmundsberg K-bentonite from the type locality at Osmundsberget in the Siljan area of central Sweden where it occurs in the lower part of the Spirograptus tur- riculatus Graptolite Zone and in the lower part of the Angochitina longicollis Chitinozoan Zone. Zircons giv- ing the latter age are from a bed previously identified as the Osmundsberg K-bentonite at the Kallholn Quarry in the same area. Based on new biostratigraphic data, the latter bed is now considered to be slightly younger than the Osmundsberg K-bentonite. The dated stratigraphic level of the ash layers is slightly younger than the base of the Telychian Stage and thus represents a minimum age for the Aeronian/Telychian Stage boundary. A U-Pb age of 〉 438 ma for the base of this stage, however, is older and in conflict with estimates in the most recent compilation of the Silurian time scale. In view of the fact that only three radio-isotopic dates from the entire Llan- dovery have been previously accepted, this new and biostratigraphically exceptionally well-controlled radio-isotopic date fills an important gap in the Lower Silurian geochronology.

我们利用“教师用康奈尔儿童行为问卷”(TRS)对美国纽约华裔儿童和中国西安儿童进行行为调查,结果显示中国、华裔及美国儿童的行为表现有许多明显的差别,他们的行为因子分析也显示了明显的不同。证明不同社会经济文化背景对儿童的行为表现模式有着明显的影响。这对儿童的早期教育,行为疾病的诊断治疗都有实际意义。同一行为问卷在不同民族不同社会经济文化背景下有着不同的因子结构,提示在移植国外行为量表时应注意到这种影响。

近两年我国电力突然短缺,已经引起政府的高度重视。由于我国风电发展的紧迫性和风电发展的潜力,特别是国际上正在如火如荼地开发风电的情景,中国- 奥地利政府间双边合作计划将风电评估列入2001～2003 年度合作计划,论文是该计划的成果之一。以我国吉林省为研究对象,采用广泛使用的风机选址算法和空间分布诊断程序( WAsP和ZAWImOD2),运用数字地形图和遥感资料获得的土地利用图,进而得到数字化的表面粗糙度,再对吉林省的风能潜力进行估算。完成了近1km2 分辨率的距地面60m高度的风速和风能密度计算,并制作了它们的分布图。这是我国第一次在较大区域上估算距地面60m 高度的风速和风能密度,其方法对我国风电资源的评估有重要的借鉴作用。结果显示最有效的风能资源在吉林省的中西部地区,而南部和东部的高风资源区位于山脊和山顶,对风能的开发有一定的限制。

森林等自然资源的保护没有当地群众的参与是不可能的。印度历史上素以人民群众参与管理自然资源而著称。然而,对森林资源来说情况并非如此,这里存在很多法律、社会和行政管理原因。1988年的新的《国家森林政策》清楚地指出,印度森林资源的管理应当有当地群众的积极参与。印度政府1990年6月的决议中提到,要将森林科学知识融进当地人民的社会文化框架之内。许多邦政府都建立了村级森林保护委员会,中央邦就是其中的一个。本文对中央邦赫尔达林业局村级群众组织的功能进行评论,也包括如何处理公共财产资源管理问题。

Effect of Ba Substitution on the Structural and magnetic Properties of BiFeO₃

Bi1-xBaxFeO3 (0 ≤ x ≤ 0.3) nanopowders were synthesized using sol-gel technique. The structural and magnetic properties were investigated using X-ray diffraction, SEm and vSm. As Ba2+ doping concentration was increased, the structure of the samples changed from rhombohedral to tetragonal or monoclinic. The structural change might be an important factor for achieving the ferroelectric properties in this material. The lattice parameters were observed to increase with increase in Ba2+ concentration. All the m-H loops showed the ferromagnetic behavior. magnetization was observed to enhance with increase in Ba concentration. The enhancement in the magnetization due to Ba2+ doping may be due to the replacement of Bi3+ ions by Ba2+ which might have resulted in the suppression of spiral spin structure.
