黔北上奥陶统五峰组黑色泥岩层段的Mo、V、U的富集系数都大于1,Ce异常的平均值为-0.07,说明泥岩形成于缺氧环境,特定元素比值(V/Cr、Ni/Co、V/V+Ni)和Ce/La显示泥岩形成于贫氧-缺氧环境。总体上,五峰组黑色泥岩沉积环境的特点是水体相对较深、沉积速率较低、呈贫氧-缺氧状态。五峰组黑色泥岩的TOC含量变化于1.31%~2.89%之间,平均值为1.98%;镜质组反射率(Ro)变化于1.93~2.25之间,平均值为2.07,反映有机质已达成熟-过成熟的干气阶段;有效厚度多在10 m之下,脆性矿物含量15%~35%之间,埋深大概在0~4000 m。这些特征表明五峰组黑色泥岩层段具备一定的形成页岩气的条件,具有形成页岩气藏的可能性,但由于厚度较薄,其页岩气资源远景目前尚不能确定。

当今社会是一个流动的社会,教师离开出生地异地教学成为一种常态。当教师移民到异地工作或在异地定居时,需要与生活的新地方建立一种新的联系,也需要对新生活的地方注入新的认知、认同与情感,这种新的认知、认同与情感,就是地方感。地方感可以重塑教师的生活态度,也可以影响教师的职业态度。在自编问卷的基础上,选取广东、重庆等地移民中小学教师相对较多的地域进行了较大范围调查,获1669份有效问卷。运用统计分析软件Amos 17.0和SPSS 24.0进行检验与分析,研究发现:地方感与教师职业态度之间存在显著正相关,教师地方感影响教师职业态度;地方性知识影响教师职业态度;地方依赖影响教师职业态度;地方依恋对教师职业态度显著于地方性知识、地方依赖的影响。因此,传承优秀地方性文化、完善移民教师激励政策和建设和谐幸福城市是提高教师地方感的有益策略,更是提高教师职业态度的有效策略。

A facile strategy using cheap and readily available precursors has been successfully developed for the synthesis of rare-earth doped hexagonal phase NaYF4 nanocrystals with uniform shape and small particle size as well as strong photoluminescence. Due to their optical properties and good biocornpatibility, these multicolor nanocrystals were successfully used as a bio-tag for cancer cell imaging. This novel synthetic method should also be capable of extension to the synthesis of other fluoride nanocrystals such as YF3 and LaF3.

针对微型化趋势下焊球的尺寸效应问题,研究了航天电子微焊点互连工艺过程中液-固界面反应与微观组织的影响规律,并对互连工艺进行了优化.具体研究了不同直径(200、400μm)的Sn-3.0Ag-0.5Cu和Sn-37Pb焊球分别在球栅阵列(BGA)器件侧金属化层(电镀Ni/Au)上进行单侧植球回流焊后的尺寸效应现象.研究结果表明:Sn-37Pb焊点界面处生成针状或短棒状的Ni3Sn4类型的金属间化合物(IMC)晶粒;Sn-3.0Ag-0.5Cu焊点界面处生成不规则的块状(Cu,Ni)6Sn5晶粒.两种类型的焊点在液-固界面反应过程中均表现出明显的尺寸效应现象,即焊球尺寸越小,界面生成的IMC晶粒直径越大,IMC层越厚.基于建立的浓度梯度控制(CGC)界面反应理论模型,揭示了界面反应尺寸效应产生的原因与界面反应进程中界面溶质原子的浓度梯度相关,较小尺寸焊点界面处的溶质原子浓度梯度较小,溶质原子扩散通量较低,形成的界面IMC晶粒较大.基于CGC界面反应理论模型,对200μm直径Sn-3.0Ag-0.5Cu焊点的单侧植球回流焊工艺参数进行了优化,工艺优化后界面生成的IMC晶粒直径减小了约60%,并且焊点在150 oC高温时效1000 h后的剪切强度提高了34%.
