The phenotypic traits of high prol.ficacy, l.w fat on the rib eye muscl. and high tol.rance to internal.parasites make the Barbados Bl.ckbel.y （BBB） sheep a val.abl. economic resource for smal. subsistence farmers on some Caribbean isl.nds. However, the determination of what is a purebred BBB sheep has l.ng been a contentious issue because of the subjectivity. It is therefore necessary to have a more rel.abl. means of identifying what is a purebred BBB sheep for purposes of conservation and breed improvement. Three geographical.y isol.ted popul.tions of BBB sheep were genetical.y anal.sed at 19 microsatel.ite l.ci. Eighteen of the microsatel.ites were found to be useful.for genetic anal.sis of the BBB sheep, based on pol.morphic information content （PIC） val.es （0.5 〈 PIC 〉 0.25）. One microsatel.ite was not useful.for genetic anal.sis based on PIC （0.111）, however it is considered to be a l.cus of interest because it is ful.y inbred （f = 1） and homozygous in al. of the popul.tions anal.sed. The anal.sis al.o showed that the purebred popul.tion of BBB sheep can be distinguished from other popul.tions by formation of distinct cl.sters when subjected to anal.sis of mol.cul.r variance （AMOVA） and the construction of a rooted consensus tree using the Neighbour-Joining method and pair-wise distances based on marker estimated kinships.

近年来,在浙江省北部钱塘江河口湾地区发现并开发了大量的晚第四纪浅层生物气藏。末次盛冰期,全球海平面的下降使河流梯度增加,下切作用增强,导致钱塘江下切河谷的形成。下切河谷内的沉积序列从下到上可划分为4种沉积相类型,分别为河床相、河漫滩—河口湾相、河口湾—浅海相和河口湾砂坝相。所有的商业浅气田和气藏都分布于太湖下切河谷和钱塘江下切河谷及其支谷的河漫滩—河口湾相砂体中。钱塘江下切河谷的河漫滩—河口湾砂体埋深30～80,m,厚3～7,m,被非渗透的黏土包围,可能代表了下切河谷内分布的潮流沙脊。快速堆积的河口湾—浅海相沉积物为生物气藏的形成提供了充足的源岩和良好的保存条件。河漫滩—河口湾相的黏土层为研究区浅层生物气藏的直接盖层,主要分布在下切河谷内,其埋深、残留地层厚度和孔隙度范围分别为30～80m、10～30,m和42.2%～62.6%。河口湾—浅海相的淤泥层为间接盖层,覆盖了整个下切河谷,其埋深、残留地层厚度和孔隙度范围分别为5～35m、10～20,m和50.6%～53.9%。黏土层和淤泥层的孔隙水压力远大于下伏砂体的孔隙水压力,其差值可达0.48MPa。在储集层和盖层分界面即浅气藏的顶部,孔隙水压力值达到最大。黏土层和淤泥层的孔隙水压力可以超过砂质储集层中气体压力和孔隙水压力之和。黏土和淤泥盖层的高孔隙水压力可能是浅层生物气被完全封闭住的最重要因素。直接盖层的封闭能力比间接盖层要好。黏土层和淤泥层的孔隙水压力消散时间很长,有时候很难达到稳定状态,这表明黏土层和淤泥层的渗透性差、封闭性好。随着埋深的增加,其压实程度和封闭性能增加。与黏土层和淤泥层相比,砂层的孔隙水压力消散较快,很容易达到稳定状态,而且消散时间与埋深无关,表明砂层渗透性好、封闭性差。气体一旦进入砂层,孔隙水就不能有效释放,导致砂层的孔隙水压力消散时间比黏土层和淤泥层的要长,这可能与生物气在孔隙水压力释放后的快速补充有关。

The present study was undertaken to determine the effects of different l.vel. of urea-N fertil.zer in addition to ipil.ipil.tree l.tter on yiel. of rice and insect preval.nce. The fiel. study was conducted at the Agroforestry Fiel. l.boratory, Bangl.desh Agricul.ural.University, Mymensingh during Jul.-December 2004. The treatments incl.ded 0, 90, 180, and 270 kg urea per hectare. Al. four treatments received five tons ipil.ipil.tree l.tter per hectare. The experiment was l.id out in a randomized compl.te bl.ck design （RCBD） with four repl.cations. The resul.s showed that the different treatments significantl. infl.enced the yiel. and yiel. component viz. total.til.ers/hill, effective til.ers/hill, fil.ed grains and unfil.ed grains/panicl.. The highest yiel. of 4.62 t·h^m-2 with an increase of 21.57% over the control.was recorded in treatment 180 kg urea·h^m-2, which was statistical.y simil.r to treatment 90 kg urea·h^m-2. The preval.nce of insects viz. green l.afhopper, brown pl.nt hopper, rice bugs, l.af fol.er and stem borers were mostl. correl.ted with N-l.vel.. The preval.nce of insects in general.gradu- al.y increased with the increase of N. Therefore, this study suggests that the combined appl.cation of organic material. （tree l.tter of ipil.ipil. and N-fertil.zer of 90 kg·h^m-2 may oroduce good yiel. whil. minimizine insect areval.nce in the rice fiel..

The devel.pment of l.ser performance model. having real.time prediction capabil.ty for the OMEGA EP l.ser system has been essential.in meeting requests from its user community for increasingl. compl.x pul.e shapes that span a wide range of energies. The l.ser operations model.PSOPS provides rapid and accurate predictions of OMEGA EP l.sersystem performance in both forward and backward directions, a user-friendl. interface and rapid optimization capabil.ty between shots. We describe the model.s features and show how PSOPS has al.owed real.time optimization of the l.sersystem configuration in order to satisfy the demands of rapidl. evol.ing experimental.campaign needs. We al.o discuss several.enhancements to l.ser-system performance accuracy and fl.xibil.ty enabl.d by PSOPS.

在四十年的职业生涯中,特别是在IAICS工作的近二十年来,在做出自己的贡献的同时,我发现跨文化交际学科的某些领域里亟待更多细致的研究。在本文中我将把一生为之努力的经验所得转化为对学科未来的建议。本文将在探讨一系列密切相关问题的基础上总结出跨文化交际研究未来面临的三大挑战。本文第一部分将从理论性视角指出我们必须面对的问题,我们必须为之集中精力相互协作以在学术和实践上取得更大成就。第二部分对于我们在教学和知识应用方面不加批判地使用技术创新的成果提出了严重的警告。第三部分和最后一部分将目光转向了种族关系。在世界上的很多地方,种族关系的紧张造成了社会的分裂,我们必须更加谨慎地运用我们的知识来解决这些问题。总之,本文将综合我个人的经历,从上述三个方面展望跨文化关系研究与实践的未来走向。文章的主题可以用这样一个问题概括:我们如何更好地挖掘潜力携手共创一个更加美好的世界?
