中华民族认同和中华民族共同体意识是研究中华民族问题时不能回避的两个概念。当前学界在研究铸牢中华民族共同体意识问题时出现了忽视中华民族认同问题,强调的“共同性”是指56个民族之间的共同性,把中华民族作为56个民族的总称,甚至否认中华民族是民族实体。中华民族认同是中华民族共同体意识的基底与主干,中华民族认同和中华民族共同体意识都体现着对“中华民族”的情感归属与赞同。铸牢中华民族共同体意识要建构科学的中华民族观,并在社会生活中传播中华民族知识,同时,要依据中华民族的结构、历史、文化等民族特点来构建中华民族的经济、政治、文化和命运共同体。

光催化因具有可以直接利用太阳能、降解几乎所有的有机污染物、还原重金属离子、反应条件温和等优点,被认为是一项理想的污水处理技术。在溶剂热合成石墨烯/C_(3)N_(4)的基础上,采用水作为还原剂在较低的温度下将贵金属Pt负载到石墨烯/C_(3)N_(4)表面,得到了具有0D-2D-2D结构的Pt/石墨烯/C_(3)N_(4)复合光催化剂。采用XRD、TEM、BET、XPS、Raman、PL等技术对Pt/石墨烯/C_(3)N_(4)的结构进行了分析,并评估了它们在可见光下光催化降解RhB和还原Cr(Ⅵ)的性能。Pt和石墨烯的协同作用,不仅可以促进光生载流子的分离传输、增大比表面积,而且超细纳米颗粒Pt的生成可以提高Pt原子的利用率、增强其催化性能。因此,Pt/石墨烯/C_(3)N_(4)复合光催化剂在可见光下表现出良好的光催化性能。当Pt和石墨烯的负载量分别为0.5%和3%时,得到的Pt0.5/G3/C_(3)N_(4)的光催化性能最强,60 min可以将初始浓度40μmol/L的RhB降解97%,表观一级反应速率常数为0.0562 min^(-1),分别是C_(3)N_(4)和G3/C_(3)N_(4)的12.5和3.2倍;80 min可以将初始浓度20 mg/L的Cr(Ⅵ)还原94%,表观一级反应速率常数为0.0119 min^(-1),分别是C_(3)N_(4)和G3/C_(3)N_(4)的14.7和2.4倍。

低温容器的漏放气速率是影响真空寿命的主要因素,为了指导夹层空间抽真空工艺,建立放气数学模型去模拟夹层漏放气特性是必要的。在已有的扩散模型基础上,Malev模型考虑材料的表面脱附和吸附对放气的影响。通过与低温液氮容器放气实验数据对比,在常温下静置放气40 h后,Malev模型预测夹层空间的放气速率与实验值的相对误差为19.39%,验证了该模型对预测夹层放气速率是有效的。结果表明,马列夫模型有合理的材料放气解释,能更加真实地反映材料表面的放气情况。对拟合出的脱附参数和吸附参数进行分析,可得出表面脱附量和吸附量在放气过程中的变化情况,该模型适用于变温度工况下夹层的放气速率预测。
