西太平洋海山富钴结壳稀土元素(REE)组成原位LA-ICPMS测定

利用激光剥蚀电感耦合等离子体质谱(LA-ICPMS)微区原位分析方法,对采自西太平洋海山具完整三层结构的富钴结壳样品进行了稀土元素(REE)含量测定,结果表明,虽然均产于西太平洋海山且均具有明显的三层结构,富钴结壳化学组成受地理位置和沉积环境影响很大。绝大多数西太平洋富钴结壳具有高∑REE、高LREE/HREE、δCe正异常和δEu基本无异常或微弱正异常的特点,显示它们主要由正常海水沉积形成。结壳不同层圈之间REE组成有较大的区别,其原因主要在于其形成环境和矿物组成不同。样品0327稀土元素总量(∑REE)由亮煤层到疏松层到外层逐渐升高,且亮煤层δCe和Y/Ho变化非常大,最大值分别为38.61和105.5,显示该层生长环境较为氧化且相对动荡,而样品0346中三层结构的∑REE都非常高,且变化趋势与0327正好相反,从亮煤层到致密层∑REE有降低的趋势。亮煤层形成时海水相对较氧化的环境有利于铁锰氧化物的形成和Ce^(4+)等稀土元素的吸附,导致其中∑REE较疏松层和外层为高,而后期磷酸盐化导致REE元素的迁移和亏损。在结壳生长剖面上,由最外层到疏松层和亮煤层,δCe呈明显上升趋势,且变化范围趋大,说明该结壳所处的海水环境在由老至新的生长过程中由相对动荡和氧化变为相对平静和还原。

对重度自闭症幼儿要求行为的塑造促进其共同注意发展的研究

本研究以一名幼儿园4岁重度自闭症女幼儿为研究对象,运用语言前期情境教学法(PMT)塑造其要求行为,根据要求行为发生频率与反应类型的变迁研究共同注意的变化,并运用早期社会沟通量表(ESCS)在干预前、干预中(第20次干预)、干预后对其共同注意进行评测。干预结果为应答性共同注意(RJA)与自发性共同注意(IJA)出现并泛化。

侵华日军关内师团的编制与分类

从全面抗战爆发到日本投降,日本陆军进行了多次整建和编制调整。本文叙述了全面抗战爆发后关内日军师团的编成和编制调整过程,介绍了关内日军师团历年的分类情况,订正了一些中文资料中的错误记述。在此基础上,概括和比较了日军不同师团在作战中的不同作用。
