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,... 详细信息

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。

＜正＞A model has been developed which simulates the temporal and spatial dynamics of greenhouse whitefly and the parasitoid Encarsia *** pest-parasitoid interaction is based on the local searching and parasitization behaviour of individual parasitoids in the whitefly-infested *** model comprises several submodels for（a） the parasitoid’s foraging behaviour,（b） the whitefly and parasitoid population development,（c） the spatial distribution of whitefly and parasitoid in the crop,and for（d） leaf *** model will allow us（1） to explain why the parasitoid can control whiteflies on some crops and not on others in large commercial greenhouses,（2） to improve introduction schemes of parasitoids for crops where control was difficult,（3） to predict effects of changes in cropping practices（*** climate,choice of cultivars） on the reliability of biological control,and finally（4） to develop criteria for the selection of natural enemies.

安全互联汽车，打造智慧生活

汽车制造业 2016年第12期 20-24页

作者： Timo van roermund 恩智浦半导体

前不久，恩智浦半导体联合CohdaWireless和西门子共同发布了《安全互联汽车，打造智慧生活》白皮书。未来，车辆的安全性同样受重视，但随着车载电子设备和软件数量的增加，将会需要额外的车载信息安全功能，保护车辆免受黑客攻击。

Orogenic garnet peridotites （metamorphic rocks containing the characteristic hP garnet-olivine mineral assemblage） exposed in ancient orogenic belts may contain quantitative data regarding formation of subcontinental/ subcratonic lithosphere, evolution of a lithospheric mantle wedge, incorporation of garnet peridotite into subducted continental crust, subsequent （ultra-）high pressure metamorphism during ongoing continental subduction and final exhumation back to subcrustal levels.
