卡拉麦里金矿带典型矿床——双泉金矿的地质地球化学特征及成因

双泉金矿是东准噶尔卡拉麦里金矿带中新近发现的一个中型构造蚀变岩型金矿床。矿床产于韧性剪切带中,赋矿地层为下石炭统南明水组地层,矿石类型主要为蚀变岩型。本文通过主要矿化阶段热液矿物毒砂成分的测定,利用相图中共生金属硫化物稳定温度范围得出主要矿化阶段的温度为300~450℃,它比通过石英流体包裹体测得的均一温度更准确地代表成矿流体的温度,由此温度平均值计算出的氢氢同位素能准确判断初始流体的来源。氢氢同位素的小范围内变化可能受成矿流体不同阶段温度的变化和组分变化的影响。综合地质地球化学资料表明,双泉金矿为与韧性剪切带有关的变质热液金矿床,韧性剪切带即为导矿构造和容矿构造;成矿物质可能主要来源于下石炭统南明水组中的火山岩和火山碎屑岩.

三类高强度悬式瓷绝缘子的成分和物相分析

为探讨高原牌70kN和进口120，210kN瓷绝缘子的成分和结构性能，文中采用原子吸收光谱（AAS）和X射线衍射（XRD）方法，对三类产品进行了检测。结果表明，有效成分除K2O外，70kN和210kN的SiO2,Al2O3,Fe2O3含量接近，主晶相基本相同，有刚玉，莫来石、石英和长石等；结晶相总量：70kN35%，120kN40%,210kN48%，这表明机械强度愈大，结晶相含量愈高，只需调整70kN原样的部分成分，粒度和工艺，即生产出高等级（如210kN)瓷绝缘子。

滇西上芒岗红色粘土型金矿常量元素地球化学

西上芒岗红色粘土剖面中常量元素的垂向分布研究表明，K20、 03、Al203在剖面中的变化一致，呈双 峰曲线变化，即在坡积带稍有富集、在残积带明显富集；而SiOz与铁、铝等在剖面中的变化相反。红色粘土与 矿区地层和矿化蚀变岩的常量元素对比分析表明了红色粘土可能来源于地层和矿化蚀变岩。常量元素之间 的相关性以及常量元素与金的相关性分析表明K20、F 03、Al203在红色粘土中为共生元素；金的富集主要受红 色粘土中褐铁矿和伊利石的吸附影响。红土化参数分析说明了红色粘土剖面经历两次红土化作用，残积带相 对于其它带经受过较强的红土化作用，但整个红色粘土剖面遭受的红土化作用不强，红土化程度低。仅处于粘 土化阶段。

金山金矿构造控矿特征及其模拟实验

在前人工作的基础上，研究金山金矿构造控制产出部位，控制金山金矿蚀变糜棱岩金矿和石英脉金矿体 及矿石类型，控制金山金矿微量元素、稀土元素、同位素及流体包裹体等地球化学特征；运用中国科学院地球 化学研究所矿床地球化学国家重点实验室中的构造地球化学(构造成矿)高温高压实验条件进行构造控矿模 拟实验，模拟高温高压条件下，岩石、矿石的变形实验，构造控制成矿物质活化、迁移聚集以及构造控制金山金 矿载金矿物成矿元素变化的模拟实验和多期多次构造应力作用下成矿物质活化、迁移模拟实验。实验结果表 明：构造活动的热动力作用下，不仅使岩石、矿石产生韧性剪切变形和脆性变形，并可看出韧性变形在前，脆性 变形在后，并叠加在韧性变形之上，构造作用能使成矿物质活化、迁移并聚集在襁皱虚脱部位，层问破碎带及 裂隙交汇部位；多期多次构造应力实验不仅使变形、破裂加剧，并使成矿物质叠加富集。实验结果与金山金矿 成矿十分近似，这不仅为研究金山金矿成矿和分布规律提供实验资料和依据，也为矿区进一步找矿提供有益 信息。

辣椒氟平均含量及其影响因素研究

西南地区是我国燃煤污染型氟中毒流行最为严重的地区，同时也是我国主要辣椒优异种质资源的分布地之一。大量的研究已经证明，辣椒和玉米等食物在用煤火烘干过程中可以吸收富集燃煤过程释放到大气中的氟，因此由燃煤型氟污染引起的食物型氟中毒也不断受到关注。 国内外至今缺乏对辣椒氟的背景值、平均含量以及影响其含量变化的因素的系统研究，只有部分研究者对燃煤型地方性氟中毒地区的辣椒进行了零星的调查分析，所采样品具有很大的局限性，远远不能代表辣椒整体的氟含量水平；且国内外迄今尚无辣椒氟含量的卫生标准，由于辣椒与其他食物和蔬菜相比具有其特殊性，而目前国家有关食品中氟的限量标准（GB2762-2005）对辣椒而言明显不合适，因此只有在对辣椒中氟的含量进行充分调查研究，才能有针对性地制定出更为科学合理的卫生标准，才能为辣椒是否受到氟污染的判别及防止辣椒氟污染提供理论依据。本研究的目的、方法、结果及结论如下所示。 目的：调查我国西南部分地区新鲜辣椒及干辣椒的氟含量水平，了解辣椒中氟的分布规律，进而确定新鲜辣椒中氟的污染判别值并探讨辣椒氟污染的防治措施。方法：按照《食品中氟的测定》（GB/T 5009.18-2003）方法对采自西南77个县市的新鲜辣椒（176个）及干辣椒（296个）进行氟的含量测定，根据地区、辣椒品种、干燥方式、储存时间及赋存状态，对辣椒中氟的含量进行统计分析。结果：采自农田的新鲜辣椒氟的几何平均含量为8.9mg•kg-1（干重，176个样，置信度95％），干辣椒样品氟的几何平均含量为19.6mg•kg-1（干重，296个样，置信度95％）。结论：研究证实辣椒的干燥与储存方式不当是导致辣椒氟污染的主要原因；通过对新鲜辣椒中氟含量的研究，证实我国现行的食品中氟限量标准(GB2762-2005)并不适用于辣椒，建议以24.7mg•kg-1 (干重)、5.2mg•kg-1 (鲜重)为新鲜辣椒氟污染判别值。

学习困难儿童智力结构及其与心理语言、视动能力关系的研究

IQ Structure, Psycholinguistic and Visual-motor Abilities Study on Children Learning Disability TONG Fang Directed by professor Zhu Liqi (Developmental and educational psychology) ABSTRACT Objective To comprehensive analyze the IQ structures, and relationships among IQ, psychometric characteristics and visual-motor integration on children disability. At same time, to probe into the family factors that influenced IQ, psycholinguistic abilities and behavior of LD children. Method (1) Downloading the papers on children learning disability from www.cqvip.com and www.wanfangdata.com, in which, the articles were collected by key words from 1985 to 2005. To conduct meta-analysis on IQ construction, compare the case group and the control group, including full IQ, verbal and practice IQ. (2) Designed with model compared and self-compared, 59 diagnosed learning disability children, tested themes with WISC, ITPA and Berry’s VMI. WISC included 10 items, 5 of which subtotal to verbal and practice IQ respectively. IPTA included 10 items, too, 5 process of which subtotal to auditory and visual perception. The first 3 items shared representation level, the other 2 of that shared automatic level.VMI had one score. Analyzed factors and levels with description and Pearson Correlation. To probe to linguistic internal alternately functions of LD children, and compare the scores of groups in different IQ. (3) Analyzed the perspective questionnaire filled by parents. Early development facts compared with model groups. Factors relationships analyzed with Kendall correlation, KOM and Bartlett’s test of sphericity, Promax Rotation. Results: (1) There have been 319 papers related with LD, in which 36 with IQ and 14 valid reports have been analyzed by Meta. FIQ’s 95%CI (confidence interval) is 2.418 ~ 0.172, VIQ between the difficulty and non- difficulty group. C-WISC-R reports were 10 papers, of which, 95%CI of FIQ is 2.424 ~ 0.676, of VIQ is 2.314 ~ 1.196, of PIQ is 2.176 ~ 0.176. The VIQ comparing the PIQ, 95%CI is 1.1 ~ -0.07 in difficulty group and 0.5 ~ -0.0046 in non-difficult group. Nevertheless, in the other 4 tests, FIQ’s 95%CI is 2.00 ~ -0.818 between LD and NLD. (2) Children psycholinguistic abilities had strong relation with Berry’s VMI test excluding auditory reception, and with perceptive factor of intelligence excluding verbal expression. Auditory reception and visual closure had strong relation with FIQ and PIQ. Grammatic closure, visual association and manual expression had strong relation with concept factor. The representational and automatic levels are depended on integration of auditory and visual procession. Lower verbal expression (VE) let to lower expression process and low scores on representational level. Lower visual sequential memory (VSM) let to lower memory process and influenced automatic level. Groups compared by IQ 90 show that LD children with under IQ 90 had lower scores on items of IPTA than with up IQ 90 excluded verbal expression. It was proved that IQ administrated the linguistic ability. Nevertheless, general abilities deficiency didn’t show influencing on the types of the perceptive delay. There was mutual function among linguistic ability on LD children. Auditory and visual level are overlapped each other. Not only show higher Decoding and lower Encoding on Auditory perception, lower Decoding and higher Encoding on Visual perception, in representation, but also higher Sequential remember, lower Closure on Audition, and lower Sequential member, higher Closure on Vision, in Automation. Nevertheless, there was no different between Representational and Automatic level, which may be the relationship of parallel or evolution. (3) Major family factors were father’s education, occupation. Lower auditory perception related to unconcerned, lower visual perception related to premature delivery and written slowly. Threatened–abortion, childbirth-suffocated were known as influencing children’s IQ and later linguistic abilities. It wasn’t shown that dosage relationship with the types of perceptive delay. Conclusion: (1) The FIQ, VIQ and PIQ of Children with LD is lower than that of NLD group. There is no significantly different between VIQ and PIQ in LD and NLD groups. (2) The objectives of ITPA and WISC tests are differently. The psycholinguistic abilities had strong relation with perceptive factor and VMI. Some facts of IPTA related with FIQ. IQ had strong administration on linguistic abilities. There was mutual function among linguistic internal abilities. (3) Family facts on IQ and psycholinguistic abilities were Father’s education, abnormal pregnant and abortion. It would be pre-show development delay in early period.
