Here, we infer the historical biogeography and evolutionary diversification of the genus Lilium. For this purpose, we used the complete plastomes of 64 currently accepted species in the genus Lilium(14plastomes were newly sequenced) to recover the phylogenetic backbone of the genus and a timecalibrated phylogenetic framework to estimate biogeographical history scenarios and evolutionary diversification rates of Lilium. Our results suggest that ancient climatic changes and geological tectonic activities jointly shaped the distribution range and drove evolutionary radiation of Lilium, including the Middle Miocene Climate Optimum(MMCO), the late Miocene global cooling, as well as the successive uplift of the Qinghai-Tibet Plateau(QTP) and the strengthening of the monsoon climate in East Asia during the late Miocene and the Pliocene. This case study suggests that the unique geological and climatic events in the Neogene of East Asia, in particular the uplift of QTP and the enhancement of monsoonal climate, may have played an essential role in formation of uneven distribution of plant diversity in the Northern Hemisphere.

云南地处青藏高原东南缘,生物多样性丰富,季风气候特征明显。新生代剧烈的构造活动形成了众多山间盆地,其间保存了大量精美的植物化石,是探讨新生代以来植被、植物多样性和地球环境演变的理想地区。但是长期以来,由于地层年代学证据的缺乏,这些新生代沉积盆地的地质年代还存在很大争议。本研究通过对滇东南地区富宁县普阳盆地的含煤地层开展深入的孢粉学研究,探讨盆地含煤地层年代及其古气候演化过程。剖面下部煤层孢粉组合以杉粉属(Taxodiaceaepollenites)为主,指示以杉科为主的湿润沼泽森林,冬春季相对湿润;剖面上部孢粉组合指示以常绿栎类为主的亚热带常绿-落叶阔叶混交林,生长山核桃粉属(Caryapollenites)、冬青粉属(Ilexpollenites)、胡桃粉属(Juglanspollenites)、枫香粉属(Liquidambarpollenites)等亚热带常见树种,气候温暖湿润,季节分明。结合新发现的哺乳动物化石证据和周边地区不同地质时代的孢粉组合,普阳盆地含煤地层的沉积时代应为晚始新世;同时,孢粉组合也表明滇东南地区植被现代化面貌至少在晚始新世就已经开始出现。

横断山南段复杂的地形地貌和多样的气候环境造就了高度丰富的植被多样性。这种植被多样性的演化与形成是植物学、生态学等领域共同关注的科学问题,而植物化石是回答这一科学问题的重要媒介。本文基于横断山南段的9个上新世化石植物群,根据其植物组成和优势成分,分析其所代表的植被类型,总结了该地区上新世的植被多样性与空间分布,并结合古环境研究资料,探讨该地区植被多样性的兴起,植被分布格局的形成,及其与环境变迁之间的关联。结果显示,横断山南段在上新世时期已经具有了多种植被类型,包括亚热带常绿阔叶林、亚热带落叶阔叶林、硬叶常绿阔叶林、针阔叶混交林、灌丛草地等,体现了丰富的植被多样性;植被类型从南面的偏热性植被向北面的偏温性植被逐渐转变,反映了当时随纬度变化的海拔梯度,植被类型与分布呈现出与现在高度相似的格局。同时,小范围内也具有适应于不同气候的植被类型,反映了当地较大的海拔落差,可能与高大山体的存在有着密切关联。我们推测,横断山南段现在丰富的植被多样性和随纬度变化的植被面貌最晚在上新世就已基本形成,但形成时间是否更早则需要更多、更老化石植物群的发现与研究。

为了提高某厂实际生产过程中夹杂物的去除效率,以某厂220 t椭圆形钢包为原型,在相似原理的基础上建立了相似比为1∶7的水模型,分析了常规的墨水示踪剂传输过程、盐水示踪剂的混匀、渣眼面积所占比例等过程和参数,并创新地采用粒子图像测速(Particle Image Velocimetry,PIV)技术研究了油层存在时水模型中的流速变化。同时进行了工业试验,分析不同方案中夹杂物数量密度的变化规律。综合探究了3种方案钢液的流场、混匀过程以及夹杂物去除情况。研究结果表明,从长轴一侧AB孔进行流量为150 L/min的等流量吹气时(方案1),其示踪剂传输过程与偏心单孔吹气情况类似,即钢液通过靠近表面的强循环流进行混匀,且混匀时间为所有方案最低;而其两孔形成的渣眼发生聚合,渣眼面积为所有方案最大。当中心对称呈180°夹角布置的AC孔以150 L/min等流量吹气时(方案2),靠近表面钢液的水平流动有所减弱,钢包整体流速下降,但渣眼面积所占比例依然较高。对于AC孔分别以50、100 L/min差流量弱吹时(方案3),渣眼面积比例大幅度降低,减弱了钢液的二次氧化。因受表面渣层(油层)影响,靠近表面钢液流动有所增强,有利于夹杂物的去除。利用工业试验对比了方案1和方案3,发现相比方案1,延长方案3的软吹时间可明显减少10μm以上夹杂物数量。综上,钢包内钢液混匀和去除夹杂物的效果并不能兼得,还需深入研究。

中间包渣层对内部宏观流动的影响往往被忽略,且针对中间包渣/钢界面下方速度的研究较少。本工作以单流无控流装置中间包为研究对象,在水模型中使用墨水和盐水示踪剂研究宏观流动现象,并使用粒子图像测速(PIV)技术测定水油界面下方以及中间包内部区域的速度分布,从而探究油层对中间包内宏观流动以及水油界面处流场的影响。结果表明,油层对中间包内示踪剂在底部的传输和扩散有促进作用,油层的存在减缓了水油界面处墨水传输过程。无油层方案中墨水向上传输趋势明显,而含油层方案中墨水主要沿底部进行传输,与无油层方案相比,墨水从出口流出的时间有所缩短。在盐水示踪剂实验中,含油层方案的RTD曲线相比无油层方案整体向左偏移,盐水溶液较早地流出中间包出口。对于整体流场,无油层方案的速度基本都大于含油层方案速度。在靠近出口和右侧壁面的区域,存在局部速度含油方案略大于无油方案的情况,油层对流体的阻滞作用变弱。对于油层方案,靠近长水口区域的垂直速度最大,随着与水油界面距离增加,垂直速度有所增加。在靠近右侧壁面的区域中,水平速度最大,但其随液面高度变化较小。
