世界百年未有之大变局加速演进,中华民族伟大复兴进入关键时期,面临新形势新任务,“两个大局”要求宣传思想文化工作必须要有新气象新作为。习近平文化思想,既是从空间维度对世界百年未有之大变局加速演进“紧迫性”的回应,又是从时间维度对中华民族伟大复兴的战略全局加速推进“全局性”的实践。习近平文化思想的形成既基于当下的时空条件,又来源于自身的生成逻辑,是在理论、文化和实践相互贯通、辩证统一中形成和发展起来的。习近平文化思想标志着历史自信和文化自信达到了新高度,它除了呈现出文化自身的繁荣兴盛,同时也展现出外在经济与内在自觉的高度自信。

作者：徐怡茅俊涛康璇童松如陈阳杰蒋林华河海大学力学与材料学院江苏南京211100

徐变是混凝土固有的时变特性,对混凝土结构和构件的受力及长期服役性能有着重大影响。以粗集料为切入点,研究粗集料的掺量、粗集料最大粒径以及粗集料与基体性质协调性等因素对超高强混凝土的力学性能和徐变性能的影响。结果表明:掺粗... 详细信息

徐变是混凝土固有的时变特性,对混凝土结构和构件的受力及长期服役性能有着重大影响。以粗集料为切入点,研究粗集料的掺量、粗集料最大粒径以及粗集料与基体性质协调性等因素对超高强混凝土的力学性能和徐变性能的影响。结果表明:掺粗集料的超高强混凝土徐变明显小于不掺粗集料的混凝土,掺粗集料可有效降低超高强混凝土的徐变,但减小粗集料的最大粒径对徐变无明显抑制效果。此外,超高强混凝土并非强度越高徐变越小,其徐变的大小主要受超高强混凝土强度与弹性模量的协同发展程度的影响。通过修正FIB MC2010模型,建立了适用于超高强混凝土的徐变预测模型。

为深入了解花生油脂含量及脂肪酸组分的遗传特性,给花生品质育种和油脂改良提供理论依据,本研究选用227份花生资源(育成品种和地方品种)组成自然群体为试材,采用变异分析、相关性分析、主成分分析、聚类分析等方法,对花生9个主要油脂性状(油脂含量及油酸、亚油酸、棕榈酸、硬脂酸、花生酸、山嵛酸、木质素酸含量、油亚比)进行多元统计分析,以揭示油脂性状之间的关联,明确提升油脂品质的关键因素。结果表明,油亚比变异系数最大,为73.66%,硬脂酸、油酸和亚油酸的变异系数较大,指标值分别为22.06%、20.86%和20.77%,品种间存在丰富的变异类型;其他性状的变异系数为3.96%~14.83%,遗传特性相对稳定。亚油酸与棕榈酸、花生酸与硬脂酸、油酸与油亚比、山嵛酸与木质素酸呈极显著正相关,油酸与棕榈酸、油酸与亚油酸、棕榈酸与油亚比、亚油酸与油亚比呈极显著负相关。9个油脂性状可综合成3个主成分因子,即高油酸因子、饱和脂肪酸因子和粗脂肪因子,这三个因子包含了种质86.25%的信息。227份种质可聚类为3大类群:第一类的油酸、木质素酸含量和油亚比在三个类群中最高,第二类的山嵛酸和棕榈酸含量较高,第三类的花生酸和硬脂酸含量较高。结果表明参试品种间差异明显,遗传多样性丰富。
