本文基于构式互动来考察“够”在用变和演变中的量性特征及其副词的规约化用法。“够”可与名词、动词、形容词组配形成构式群。随着主观性增强,“够”由表客观的足量向抽象的程度量虚化,词性上由判断动词向程度副词演变。其语法化等级呈现出非均质性,其中“够+A”时语法化等级最高。功能上“够”实现了客观的定量评估向主观的模糊定性转变。

Intercalated transition metal dichalcogenides(TMDCs)attract much attention due to their rich properties and potential *** this article,we grew successfully high-quality V_(1/3)TaS_(2) crystals by a vapor transport *** measured the magnetization,longitudinal resistivityρxx(T,H),Hall resistivityρxy(T,H),as well as performed calculations of the electronic band *** was found that V_(1/3)TaS_(2) is an A-type antiferromagnet with the Neel temperature T_(N)=6.20 K,and exhibits a negative magnetoresistance(MR)near T_(N).Both band structure calculations and Hall resistivity measurements demonstrated it is a magnetic semimetal.

目的探讨铜离子载体伊利司莫诱导子宫内膜癌细胞发生铜死亡的机制。方法采用不同浓度伊利司莫和氯化铜处理HEC-1-A细胞。细胞计数试剂-8(CCK-8)法检测细胞增殖。酶联免疫吸附测定(ELISA)法检测线粒体呼吸链复合物Ⅰ、Ⅱ、Ⅲ和Ⅳ。实时荧光定量聚合酶链反应(qRT-PCR)检测mRNA表达。免疫印迹法(Western blotting)和免疫组化法检测蛋白表达。结果单独加入伊利司莫或氯化铜不影响细胞的存活率,但同时加入50 nmol·L^(-1)伊利司莫和1μmol·L^(-1)铜离子使HEC-1-A细胞存活率明显下降(P<0.01)。伊利司莫诱导的HEC-1-A细胞死亡并不涉及细胞凋亡。采用50 nmol·L^(-1)伊利司莫和1μmol·L^(-1)铜离子处理HEC-1-A细胞后,线粒体呼吸链复合物Ⅰ、Ⅱ、Ⅲ的水平显著升高。敲减人铁氧还原蛋白1(FDX1)可明显抑制HEC-1-A细胞的铜死亡(P<0.01)。此外,FDX1在子宫内膜癌组织中低表达。结论伊利司莫可能通过FDX1/线粒体呼吸途径促进子宫内膜癌细胞发生铜死亡。

Resources are the base and core of education information, but current web education resources have no structure and it is still difficult to reuse them and make them can be self assembled and developed continually. According to the knowledge structure of course and text, the relation among knowledge points, knowledge units from three levels of media material, we can build education resource components, and build TKCM （Teaching Knowledge Combination Model） based on resource components. Builders can build and assemble knowledge system structure and make knowledge units can be self assembled, thus we can develop and consummate them continually. Users can make knowledge units can be self assembled and renewed, and build education knowledge system to satisfy users＇ demand under the form of education knowledge system.

大学体育文化作为一种亚文化,能够丰富体育文化内涵与外延,培育青年体育核心素养,对体育文化的传承意义重大。本文采用文献分析法、逻辑分析法、比较研究法,从体育历史与制度、体育教学模式与组织架构、体育教育目标与理念、运动项目与竞技水平4个方面对中韩大学体育文化进行比较分析。研究认为:(1)中韩大学体育文化因高等教育的历史流变而各具特色,中国大学体育文化虽受西方模式影响,但具有鲜明的“内生性”特征,其主要资金来源是国家财政预算;韩国大学体育文化的现代化与国际化程度高(私立占绝对话语权),其主要资金来源于韩国财阀。(2)政治属性与文化背景的双重叠加,造成了中韩大学体育文化在价值观念、组织架构、竞技水平等方面的显著差异。(3)中国大学体育文化崇尚道德教育,更强调体育教育的普及和集体主义价值,以人化的体育价值促进学生全面发展;而韩国大学体育文化侧重于专业体育人才培养,追求竞技水平与国际竞争力。建议:未来中国大学体育文化可立足本土,借鉴韩国大学运动员职业化、体育赛事等方面的先进经验,助力我国大学体育文化在新时期、新阶段下的高质量发展。

A feasible strategy for realizing the Majorana fermions is searching for a simple compound with both bulk superconductivity and Dirac surface *** this paper,we perform calculations of electronic band structure,the Fermi surface,and the surface states,and measure the resistivity,magnetization,and specific heat of a TlSb compound with a CsCl-type *** band structure calculations show that TlSb is a Dirac semimetal when spin-orbit coupling is *** is first determined to be a type-Ⅱsuperconductor with T_(c)=4.38 K,Hc1(0)=148 Oe,H_(c2)(0)=1.12 T,andκ_(GL)=*** also confirm that TlSb is a moderately coupled s-wave *** we cannot determine the band near the Fermi level EF that is responsible for superconductivity,its coexistence with topological surface states implies that the TlSb compound may be a simple material platform to realize the fault-tolerant quantum computations.

The synthesis of TiN and Al2O3 by in situ injection of reactive nitrogen gas into molten Al alloys has been evaluated over the temperature range from 1000 to 1600℃. It is shown that TiN and Al2O3 can be formed in melt with nitrogen and surplus oxygen (in vacuum room of the induction furnace) as the reactive gases over 1000℃. Up to 2.1 wt pct Al2O3 and 5.2 wt pct of TiN in situ phases in an Al alloy has been formed in a range of size from 0.8 to 5 μm. The formation mechanism of TiN and Al2O3 is discussed in this paper.
