| 1 | 伊通上地幔剪切带捕虏体中富铝尖晶石的地球化学特征显示文摘伊通上地幔剪切带中辉石岩、二辉橄榄岩和易剥橄榄岩是3个主要地幔捕虏体,其中尖晶石的化学成分以富铝为特征。辉石岩中尖晶石在薄片下呈绿色,为铝含量高、铬含量低的铝尖晶石;与之相比,二辉橄榄岩和易剥橄榄岩中尖晶石在薄片下呈棕色,为铝含量相对较低、铬含量相对较高的富铝铬尖晶石。尖晶石的颜色与Al、Mg、Cr、Fe含量有关。在不同捕虏体中尖晶石成分具有不同的变化范围,尖晶石化学成分之间存在一定的相关性,Mg#与Cr#,Mg#与Fe2+和Cr与Al呈现负相关性,而Mg#与Al#呈现出正相关性,反映不同捕虏体中尖晶石具有同一来源和成因联系。在地幔岩石部分熔融和结晶过程中Cr和Al的分异明显。固溶体条件下基本服从八面体Cr Al替代关系,而不同地幔捕虏体中尖晶石的成分差异是岩浆部分熔融和结晶过程中元素分异、固溶体离子替代的结果。 | 贾大成 邢立新 潘军 M.J.van Bergen H.van Roermund | 2006 | 吉林大学学报(地球科学版)2006，36，4： | 7 |

| 3 | 伊通新生代玄武岩中辉石岩捕虏体的尖晶石成分分带显示文摘伊通新生代玄武岩中存在3种不同成因的捕虏体,其中上地幔岩浆分异结晶形成的辉石岩捕虏体中尖晶石具有独特的成分分带。电子探针分析显示在尖晶石矿物的边缘富Al,而贫Mg、Fe和Cr,矿物中心富Mg、Fe和Cr,而贫Al,从中心向两侧基本对称。从尖晶石成分分带的元素分布特征判断,其形成不是固溶体相平衡过程中的离子扩散,而可能是化学平衡过程中结晶矿物与熔浆之间化学成分平衡的结果,属于化学平衡导致的成分分带。从尖晶石矿物中心到边缘的温度变化不能反映矿物形成后所经历的温度变化状况,与尖晶石共生矿物的二辉石地质温度计所能代表的地质意义是矿物中心的温度(~1006℃).反映矿物开始结品时的温度状态。 | 贾大成 裴尧 杜有实 M.J.van Bergen H.van Roermund | 2007 | 吉林大学学报(地球科学版)2007，37，3： | 0 |

| 5 | Supplementing oat hulls to the diet of suckling piglets altered their intestinal tract and colonic microbiota development显示文摘Current study evaluated the effect of a fine and coarsely ground insoluble dietary fibre source on the gastrointestinal development of suckling pigs.Oat hulls(OH)were selected as a model feedstuff,rich in cellulose,lignin,and insoluble dietary fibre.Three experimental supplemental diets were formulated:a finely ground,low fibre and nutrient dense diet served as control(CON).For the 2 high fibre diets,15%heat-treated starch in CON was exchanged with OH,either finely(OH-f)or coarsely ground(OH-c).Litters of 10 primi-and multiparous sows(mean litter size 14.6±0.84)were used.Within a litter,experimental diets were allotted to triplets of 4 piglets.From approximately 12 d of age,piglets’individual feed intakes were recorded 2 times per day when separated from their dam for 70 min.Piglets could suckle with their dam for the remainder of the day.On d 24 and 25,from the total pool of 120 piglets,seven healthy well-eating piglets per treatment were selected for post-mortem evaluation,resulting in 14 replicates per treatment.Consumption of OH-c and OH-f did not impede clinical health and production performance of piglets.The full stomach weights tended to be greater for OH-c compared to OH-f whereas CON was intermediate(P=0.083).Supplementing OH significantly increased ileal villus height and caecal dry matter concentration(P<0.05).For the colon,OH increased its length,contents weight,short-chain fatty acid concentration and reduced total bacterial count as well asγ-proteobacteria count and proportion(P<0.05).The OH-c treatment specifically increased full gastrointestinal tract weight and caecum contents weight compared to piglets fed CON and OH-f.Furthermore,OH-c reduced colonic crypt depth when compared to OH-f(P=0.018).In conclusion,supplementing OH to a diet for suckling piglets exerted subtle developmental effects on gastrointestinal morphology and colonic microbial community.These effects were largely independent from the particle size of the OH. | Hubèrt M.J.van Hees Koen Chiers Leo A.den Hartog Theo A.T.G.van Kempen Dominiek Maes Sam Millet Geert P.J.Janssens | 2023 | Animal Nutrition2023，，1： | 0 |
| 6 | 东印度尼西亚弧-陆碰撞区地球化学与构造关系及对澳大利亚被动边缘俯冲作用的意义显示文摘当一个被动大陆边缘到达沿岛弧或活动边缘的一条俯冲带时,产生的碰撞就会引起常导致俯冲停止的构造扰动。弧-陆碰撞和陆-陆碰撞发生在大部分的地球史中,例如在从地中海西部到东南亚的特提斯中。在这些背景中陆壳继续进行下冲或俯冲的程度不仅对地表构造过程有重要控制,而且还为地壳物资再循环到地幔提供了基本条件。 | M.J.Van Bergen 韩林 | 1994 | 海洋地质译丛1994，0，4： | 0 |
