狼群重生日记（一）

前言 2006年9月16日,我接受了一家NGO组织的邀请,前往中国北部的锡林郭勒盟。我将在那里度过60天。在这60天中,我会追随一群“自然卫士”完成一件让我感觉战粟的任务——寻找草原狼群。     

滇川西部金沙江石炭纪蛇绿岩SHRIMP测年:古特提斯洋壳演化的同位素年代学制约

本文应用SHRIMP方法精确测定了金沙江蛇绿岩带中蛇绿岩的辉长岩和斜长岩、呈脉状产于辉长岩和变质橄橄岩中的斜长花岗岩、以及呈岩株状侵入蛇绿岩中的花岗闪长岩的锆石U-Pb年龄,提供了古特提斯洋壳演化的年代学制约。滇西之用层状角闪辉长岩的年龄为328±8Ma,书松斜长岩为329±7Ma,白马雪山辉长岩为282～285Ma,它们可能反映了海底扩张不同阶段的时代。研究还表明,在这些辉长岩和斜长岩中,部分锆石记录了375～352Ma的略老的年龄,暗示蛇绿岩浆活动可能始于晚泥盆世。在金沙江蛇绿岩中,滇西娘九丁斜长花岗岩和川西雪堆斜长花岗岩,具有高硅低钾的成分特征。但是,这些岩石的REE总量高,LREE富集;Sr初始值高,达0.7058～0.7070;在其锆石组成中,存在继承锆石。这些证据表明斜长花岗岩中存在陆壳物质的混染,可能与洋壳俯冲消减有关。娘九丁斜长花岗岩的年龄为285±6Ma,雪堆斜长花岗岩为300±5Ma,记录了古特提斯洋壳俯冲消减事件。滇西吉义独花岗闪长岩,呈岩株状侵入蛇绿岩中,年龄为263±6Ma,限定了蛇绿混杂岩的年代上限。

上海市学生人群防震减灾科普工作现状调查研究——以初中生群体为例

为了全面系统评价上海市学生人群的防震减灾科普效果,准确了解其科普需求,课题组在2014年下半年选取上海市某初级中学的部分学生作为示例,从科普知识的认知程度、需求与认知偏好、对宣传工作满意度评价、科普教育在学校开展的情况这四个方面进行问卷调查,以便及时总结经验,为今后在该人群中更加科学、高效地开展防震减灾科普宣传工作打下坚实的基础。     

大同盆地舆桑乾河上游之流向

山西全省之地形,通常成以一大高原目之。惟境内因山岭起伏,河流纵横,高原被其分割,间以河流冲积所成之狭长盆地,形势颇为零落。亘长山岭,耸出於地表之上者,或闪褶皱关系,构成重要之山脉,如太行吕梁等山脉是;或因断层关系,而为断层之断壁者,如恒山罗云山等是;其他由於火成岩之侵入者,如塔山紫金山等是。又近在本省之东北部山峯中,行被认为火山之遗迹者,见於桑乾河上游盆地之北边沿,为黄土所覆盖,保存极为完好。     

Combined effects of light intensity and NH^＋4-enrichment on growth,pigmentation, and photosynthetic performance of Ulva prolifera （Chlorophyta）

The aim of this study was to investigate the effects of light intensity and enhanced nitrogen supply on the growth and photosynthesis of the green-tide macroalga, Ulva prolifera. Thalli of U. prolifera were grown in natural or NH 4 +-enriched seawater under two different light intensities for 7 days, and then the growth rate, pigmentation, and photosynthetic performance of the thalli were evaluated. The results show that the relative growth rate(RGR) was markedly higher under the high light level than under the low light level. Enrichment with NH 4 + enhanced the RGR under high light intensity, but did not affect RGR under low light intensity. In low light conditions, NH 4 +-enrichment resulted in a marked decrease in the maximal photosynthetic rate( P m) and the maximum carbon fixation rate( V max), but it did not affect the half saturation constant for carbon( K 0.5) or the ratio of V max to K 0.5, which reflects the carbon acquisition efficiency. In high light conditions, P m, K 0.5, and the dark respiration rate( R d) increased under NH 4 + enrichment, but V max and the V max / K 0.5 ratio decreased. Regardless of the light intensity, NH 4 +-enrichment did not affect the apparent photosynthetic efficiency( α), which refl ects the ability of the alga to use light energy at low light levels. Under both low and high light intensities, the chlorophyll a(Chl a), chlorophyll b(Chl b), and carotenoids(Car) contents in thalli were higher in NH 4 +-enriched than in natural seawater, except that there was a decrease in the Chl b content of thalli in NH 4 +-enriched seawater under low light intensity. Therefore, NH 4 + enrichment improved the growth and photosynthetic performance of U. prolifera under high light intensity, but not under low light intensity. We discuss the possible mechanisms underlying these physiological responses.

雪宝顶绿柱石-白钨矿脉状矿床富挥发分成矿流体特征及其示踪与测年

研究发现四川雪宝顶绿柱石-白钨矿脉状矿床矿物包裹体存在多个流体相, 经单包体激光拉曼光谱测试表明, 除固相子晶外, 流体相自中心向外依次是气相CO₂、液相CO₂、贫水CO₂液相和盐水溶液相. 通过对流体包裹体成分、C, O和稀有气体He, Ar同位素示踪与测年研究, 认为该矿床富含挥发组分的成矿流体主要来源于岩浆期后热液, 成矿元素富集受控于深成碱性岩浆活动与地壳物质混合作用.
