Purpose: To observe the refractive status, especially the tendency for evolution of high myopia, in eyes of Chinese school children from Xi’an ***: The study was conducted in 11514 eyes of the 5757students aged between 7~18 years in Xi’an city primary and high schools. The inclusion criterion was >-6D of the spherical equivalent refraction. The object ophthalmic examinations were done, included non-cycloplegic objective refraction, visual acuity, intraocular pressure, fundus evaluation by ophthalmologists and nurses with professional training. Specially designed questionnaires were filled in and the data were statistically analyzed with ***: Of 11514 eyes, the detection rate was 81.4%(9376eyes) for myopia and 5.3%(615 eyes) for high myopia. High myopia was found in 2.6%.(300 eyes).of right eyes, 2.7%(315 eyes) in left eyes, and 2.4%(275 eyes) were in boys and 2.9%(340 eyes) in girls. Among 12 school grades, the detection rates of high myopia increased significantly with student age, with 0.9% in the 1stgrade of primary school and12.5% in the 3rd year of senior middle school. The average refractive error of spherical equivalent refraction was(-7.43±1.29) D with 95% confidence interval(-7.54,-7.33). No significant differences were found between the right and left eyes or both genders. The distribution of myopic severity was lowest(-6D).in primary school students younger than 12 years,was higher(-8D) in junior middle school students older than13 years, and highest(-13D) in senior middle school ***: A continuous growth was evident in the severity of high myopia throughout 12 years of primary and middle school except for the first year of primary school, with growth occurring in two transitional stages between the senior primary and junior middle school years, and between the junior and senior middle school years. The distribution of high myopia was lowest, at-6D, in primary school, increased to-8D in junior middle school, and progre

霞石岩的成因及深部碳循环

岩石学报 2024年第7期40卷 2238-2254页

作者：石苡宁张招崇程志国中国地质大学(北京) 地质过程与矿产资源国家重点实验室北京100083 中国地质大学(北京)深时数字地球前沿科学中心北京100083

霞石岩是以发育霞石和单斜辉石斑晶为特征的过碱性火山岩,其单体出露体积较小,常以碳酸岩-碱性杂岩体或小体积熔岩流的形式广泛分布在板内环境中,产出的时代跨度大(从太古宙至今),产出量总体上随地球的演化而增多。通常认为霞石岩在喷... 详细信息

霞石岩是以发育霞石和单斜辉石斑晶为特征的过碱性火山岩,其单体出露体积较小,常以碳酸岩-碱性杂岩体或小体积熔岩流的形式广泛分布在板内环境中,产出的时代跨度大(从太古宙至今),产出量总体上随地球的演化而增多。通常认为霞石岩在喷发过程中上升速度快且较少受到地壳物质混染,可以很好地反映地幔源区特征。然而,目前对其源区性质仍存在争议,其争论的焦点在于源区是否存在碳酸盐,即碳酸盐化源区是否是霞石岩形成的必要条件。本文基于全球各地霞石岩的地质-地球化学数据分析,将其分为两组:第一组霞石岩的SiO_(2)和碱含量(Na _(2)O+K_(2)O)变化范围较大,出现Rb、K、Pb、Zr、Hf、Ti、Y元素的负异常,放射性同位素组成普遍较为亏损;第二组相较第一组具有更高的SiO_(2)、碱含量,更低的MgO、TiO_(2)、P_(2)O_(5)含量和Na _(2)O/K_(2)O比值,并出现U、Nb、Pb、Zr元素的正异常以及Ti元素的负异常,Nb-Ta及Zr-Hf发生分馏,放射性同位素组成较第一组更富集。结合实验岩石学结果,研究认为第一组霞石岩的原始熔体为碳酸盐化榴辉岩部分熔融熔体与地幔橄榄岩反应形成的富碳硅酸盐熔体,其直接喷发或只经历低程度的分离结晶作用;第二组霞石岩与第一组霞石岩具有相似的源区特征,但熔体经历了强烈的分离结晶及不混溶作用。因此,碳酸盐化源区是霞石岩形成的必要条件。对霞石岩露头的时间分布进行统计发现,霞石岩最早形成于太古宙,但形成量在约550Ma和80Ma突增,碳酸盐俯冲通量的增加可能是导致霞石岩形成量突增的原因,而形成于太古宙的霞石岩说明太古宙地幔中存在局部的“碳”富集或输入。

重写《刘三姐》

随着二十世纪五六十年代彩调剧、歌舞剧和电影《刘三姐》的问世，刘三姐这一壮族民间传说中的歌仙已成为海内外家喻户晓的人物形象。刘三姐作为一个文化符号，今天既已变成壮族文化的一个历史象征，也已成为壮族文化的一个现代图嘴。正因为刘三姐这一文化符号对于壮族文化、壮族民族形象的非凡意义，所以我认为在全球化和建设和谐文化的内外双重时代语境中，再度审视和重新定义刘三姐这一文化能指的内涵，是壮族文化创新与发展所必须迈出的一个步骤。

新的生活、新的矛盾、新的人物和新的情感,是当下现实主义文学必须面对并致力发现与表现的对象。王华敏锐地洞察了这一点,其近年来发表的作品体现出了现实主义写作的新探求,显示出她对现实主义把握现实又给人以超越现实的可能性的深刻认识,对现实主义与读者的审美趣味和审美共鸣之间关系的切实理解,以及由此产生的以现实主义视角与手法认识、表达社会生活的自觉意识。

本文副题之所以用“试”字，是因为我并没有读过潘琦的全部散文。作者签名赠我的漓江出版社出版的《广西当代少数民族作家丛书·潘琦卷》，民族出版社出版、徐治平主编的《广西散文百年》和报刊上见到的一些零星作品，构成了我和作者及有关研究者对话的基础。相对于达九卷之多的《潘琦文集》，这一点基础显然不够，但囿于资料不完备，也只能尝试而为之了。不过，《广西当代少数民族作家丛书·潘琦卷》这本书，我理解应是作者的代表性作品的一个结集，所以以这本书作为立论的主要依据，也还不至于太离谱吧。
