1西藏罗布莎蛇绿岩铬铁矿中金刚石的研究显示文摘在西藏罗布莎豆荚状铬铁矿中发现过金刚石,但迄今仍有人因为自己所取的小试样中没有分离出金刚石而否定罗布莎等地金刚石的存在。由于金刚石涉及西藏雅鲁藏布江缝合线和蛇绿岩、铬铁矿成因等问题,笔者重新在罗布莎铬铁矿中取样,经过选矿,又在1500kg样品中选出了25粒金刚石和近70种伴生矿物。这就表明西藏金刚石是的确存在的,而且它和蛇绿岩的铬铁矿同是深部成因的产物。白文吉 杨经绥 P.Robinson 方青松 张仲明 颜秉刚 胡旭峰 2001地质学报2001,75,3:41
2本科阶段人才培养中的分层次地学实践教学体系建设显示文摘分层次地学实践教学体系是创新人才培养的重要内容,中国地质大学(北京)经过50多年不断改革和探索,总结出以周口店地质测量实习为纽带的三层次地学实践教学体系,被证明是符合地学教学规律和行之有效的。然而,由于三层次教学间相对独立操作,从而造成各层次间在教学内容、教学方式、教学目标等的衔接尚不完全协调,进而在高端人才培养,特别是创新人才输出方面出现问题。本文针对此问题,在多年不同类型实践教学工作基础上,通过调查、总结和研究,提出了有针对性进行改革的基本思路和具体措施,并进一步提出已经或可能出现的问题。颜丹平 张维宸 王根厚 赵国春 徐德斌 张维杰 P.Robinson 2009中国地质教育2009,18,1:11
3剪切波弹性成像与传统超声及MRI对骨肌系统软组织良恶性肿瘤鉴别诊断能力的比较显示文摘目的探讨剪切波弹性成像(SWE)与单一超声检查或超声联合MRI检查相比,能否提高软组织肿块良恶性诊断的准确性。材料与方法2015年12月—2017年3月间连续招募预行软组织肿块活检的206例成年病人(年龄18~91岁,平均57.7岁),其中男89例(年龄21~91岁,平均56.0岁),女117例(年龄18~88岁,平均59.1岁),活检前病人接受了B超、MRI和SWE检查。A.N.Tavare A.M.Alfuraih E.M.A.Hensor E.Astrinakis H.Gupta P.Robinson 田禹(译) 刘晨(校) 2019国际医学放射学杂志2019,0,2:4

9Regeneration of pitch pine (Pinus rigida) stands inhibited by fire suppression in Albany Pine Bush Preserve, New York显示文摘The Pine Barrens in New York State are dominated by pitch pine(Pinus ridgida) and scrub oaks(Quercus ilicifolia and Q. prinoides). With fire suppression over the last 90 years or so, P. rigida regeneration has become sparse, even in areas set aside to preserve this type of vegetation. We evaluated the effects of fire and an alternative disturbance(mechanical removal of vegetation)for increasing P. rigida regeneration in the Albany Pine Bush Preserve in eastern New York State. By comparing cover, diameter and height of P. rigida, Q. ilicifolia, Q.prinoides, and Vaccinium spp.(blueberry) growing on the sites with a known fire history, we documented structural and compositional changes in the vegetation since its establishment. We also compared sites on which Quercus sprouts were controlled through mechanical removal. In the years following a disturbance, height and cover of Q. ilicifolia increased continuously and the species became increasingly competitive. Both the density of P. rigida seedlings and Vaccinium cover decreased significantly as the diameter and height of Quercus increased. Our results confirmed that the dominance by P. rigida could be attributed to periodic fires at intervals of 20–25 years. We conclude that removing Q. ilicifolia can favor P. rigida dominance on the barren without fire by releasing pine seedlings from competition.Chang-Seok Lee George R.Robinson Ingrid P.Robinson Hansol Lee 2019Journal of Forestry Research2019,30,1:0
