学科核心素养是核心素养在教学领域的具体化,深入探究其理论根基与实践向度,对学生成长起着非常关键的作用。学科核心素养培育兼具认识论、方法论和价值论三重理论根基。其中,发生认识论从认识论角度明确了学科核心素养培育的过程与要素,马克思实践观从方法论层面强调学科核心素养培育的活动形态与结构,人本哲学从价值论视角重申学科核心素养培育的本质属性与根本方向。从现实基础来说,学科核心素养培育发轫于“立德树人根本任务”,生长于“中华优秀传统文化”,生成于“时代课程教学改革”。在实践向度深思,应以多边协同促成学科核心素养培育的大环境;用学科跨界打破学科核心素养培育的“竖井式”分科边界;把实践教学作为学科核心素养培育的“源头”要素和“关键”环节;探索新质教育评价体系,立教育强国建设之功。

Background Seasonal freeze-thaw(FT) processes alter soil formation and cause changes in soil microbial communi-ties, which regulate the decomposition of organic matter in alpine ecosystems. Soil aggregates are basic structural units and play a critical role in microbial habitation. However, the impact of seasonal FT processes on the distribution of microbial communities associated with soil pores in different aggregate fractions under climate change has been overlooked. In this study, we sampled soil aggregates from two typical alpine ecosystems(alpine meadow and alpine shrubland) during the seasonal FT processes(UFP: unstable freezing period, SFP: stable frozen period, UTP: unstable thawing period and STP: stable thawed period). The phospholipid fatty acid(PLFA) method was used to determine the biomass of living microbes in different aggregate *** The microbial biomass of 0.25–2 mm and 0.053–0.25 mm aggregates did not change significantly dur-ing the seasonal FT process while the microbial biomass of > 2 mm aggregates presented a significant difference between the STP and UTP. Bacterial communities dominated the microbes in aggregates, accounting for over 80% of the total PLFAs. The microbial communities of soil aggregates in the surface layer were more sensitive to the sea-sonal FT process than those in other soil layers. In the thawing period, Gram positive bacteria(GP) was more dominant. In the freezing period, the ratio of Gram-positive to Gram-negative bacterial PLFAs(GP/GN) was low because the enrichment of plant litter facilitated the formation of organic matter. In the freezing process, pores of 30–80 μm(mesopores) favored the habitation of fungal and actinobacterial communities while total PLFAs and bacterial PLFAs were negatively correlated with mesopores in the thawing *** The freezing process caused a greater variability in microbial biomass of different aggregate fractions. The thawing process increased the differences in

目的全面了解年轻妇科癌症患者社会疏离的真实体验。方法采用目的抽样法,选取2023年6—8月在武汉市某三甲医院妇科肿瘤病房治疗的患者作为研究对象,对符合纳排标准的19例年轻妇科癌症患者进行半结构式访谈。采用Colaizzi内容分析法对资料进行分析与主题提炼。结果通过对访谈资料的分析归纳,提炼汇总为3个主题:负性情绪体验(孤独感与无助感、病耻感与自卑心理、无意义感与缺乏社交兴趣)、客观行为改变(以保护自我为目的的自我承受、以保护他人为目的的隐匿心声、沟通交流障碍)、外界支持不足(医护专业支持不足、家庭及亲友支持不良、同伴支持受限)。结论年轻妇科癌症患者正面临较高的社会疏离。医护人员应结合患者的实际情况及个体化因素,制定针对性干预方案;加强患者的心理支持、医疗信息支持及健康指导,调动全方位社会支持系统,促进患者积极融入社会,早日回归正常生活。

As significant differences in cellular physiology, metabolic potential and genetics occur among strains with morphological similarity, the screening of appropriate microalgae species for effective CO2 fixation and biodiesel production is extremely critical. In this study, ten strains of Chlorella were cultivated in municipal wastewater influent（MWI） and their tolerance for MWI, CO2 fixation efficiency and lipid productivity were assessed. The results showed that the biomass concentrations of four strains（Chlorella vulgaris, Chlorella64.01, Chlorella regularis var. minima and Chlorella sp.） were significantly higher than other strains. When the cultivation systems were aerated with 10% CO2, Chlorella sp. showed the highest CO2 fixation efficiency（35.51%）, while the highest lipid accumulation（58.48%） was observed with C. vulgaris. Scanning electron microscopy images revealed that the cells of both Chlorella sp. and C. vulgaris kept their normal morphologies after 15 day batch *** findings indicated that Chlorella sp. and C. vulgaris have fairly good tolerance for MWI,and moreover, Chlorella sp. was appropriate for CO2 fixation while C. vulgaris represented the highest potential for producing biodiesel.

目前高熵陶瓷的研究主要集中在通过元素的改变或增加获得高性能陶瓷上,忽视了由于成分的复杂性而造成的高熵陶瓷晶体结构的变化及其对性能的影响。本研究基于原位XRD技术,系统研究了高熵(Mg,Co,Ni,Zn)Ti_(2)O_(5)形成过程、高熵化后晶体结构及热膨胀系数的变化。研究发现,随温度上升,反应物首先生成高熵中间相,最终在1400℃生成高熵(Mg,Co,Ni,Zn)Ti_(2)O_(5)陶瓷。与其单相相比,高熵(Mg,Co,Ni,Zn)Ti_(2)O_(5)晶格常数及热膨胀各向异性均发生变化。以上研究表明原位XRD技术可用于阐明高熵假板钛矿陶瓷形成过程中晶体结构演化及性能变化过程,并在高熵陶瓷晶体结构解析方面具有很大的应用前景。

H13 powder is cladded on steel P20 （base） by continuous COe laser, and the influence of technological pa rameters such as the laser power is analyzed. The 3-D model of synchronous powder feeding is built under Gauss heat source. The simulative results in the heat affected zone are compared with the experimental ones, and the average er rors of width and depth are 15% and 4.5%, respectively. It is found that the simulative results provide basic data for investigating of laser cladding further.
