为深入贯彻习近平总书记在高校思想政治工作会议上的重要指示,构建将思政课程与课程思政协同进行的新型育人模式,本文以我校化学师范专业《无机化学》课程中的“化学反应方向的判断”作为课程思政教学设计案例,从教学目标、教学内容、课程思政元素及教学活动的组织等方面探讨了课程思政在“化学反应方向的判断”课例中融合进行的教学案例设计方法及实施策略。 相似文献

工程教育专业认证的核心理念得到了广泛认同,目前我国高校正在有序开展并大力推进工程教育专业认证工作。然而,高校在推行以价值引领为目标的课程思政改革的过程中存在认识上的误区。文章从课程思政和专业认证的接受度、课程思政德育目标设置和专业认证的毕业要求、课程思政和专业认证的教学文件、课程思政和专业认证的育人格局设计四个角度论述了两者的关系及认识上存在的误区,指出了课程思政教育与工程教育专业认证的重合点、相似性和相容性,并提出将课程思政与专业认证相融合,在践行“价值引领”和“以学生为中心”理念的同时,实现专业和课程的同步提升。 相似文献

Porous microspheres with different sizes were prepared through solvent evaporation method with ethylcellulose as a matrix material and abamectin as a core material. The abamectin-loaded microspheres were characterized through scanning electron microscopy (SEM), dynamic light scattering (DLS), Fourier transform infrared spectroscopy (FTIR), and thermogravimetric analysis (TGA). The chemical structure of the microspheres was determined through FTIR. DLS analysis showed that the diameter of the microspheres range from 10 to 100 μm. SEM analysis revealed that the inner structure of the microspheres is characterized by a porous network. TGA revealed that the microspheres are thermally stable below 125 °C. The controlled release of abamectin from the microspheres into water and soil was also investigated. Abamectin was released from microspheres into water through diffusion. The release of abamectin into soil was mainly caused by erosion, a result that was verified through SEM. 相似文献

Development of microstructure in four hydrothermal reactions has been undertaken using scanning electron microscopy. These are clinker, clinker-sand, slag-lime and slag-lime-sand hydrothermal reactions. The microstructure of clinker hydration products displayed crumpled foils and tabular masses of calcium silicate hydrates; few cubic crystals of hydrogarnet appeared only during the initial stage of the reaction. In clinker-sand mixture the C-S-H phase was the only product identified. In slag-lime hydration the microstructure displayed both of the hydrogarnet crystals and the C-S-H phase. The hydration of slag-lime-sand mixture (an optimum composition) was associated with the formation of ill-crystallized tobermorite and crystalline 11A tobermorite as the main products. 相似文献

西玛津在甘蔗及土壤中的残留消解动态 总被引:1,自引:0,他引:1
为了探明西玛津使用后在甘蔗及其土壤中的残留降解规律,采用气相色谱法研究了西玛津90%水分散粒剂在甘蔗及其土壤中的残留消解降解动态和最终残留实验。结果表明:西玛津在甘蔗和土壤中的降解动态方程分别为Ct=19.157e-0.0587t和Ct=1.689 8e-0.036t,半衰期分别为11.8 d和19.3 d;以1 647 g a.i./hm2和2 470.5 g a.i./hm2的剂量在甘蔗田进行喷雾处理,收获期甘蔗和土壤中的最终残留量分别小于0.01 mg/kg和0.02 mg/kg。 相似文献

The metabolism of malonaldehyde (MA) was investigated in vivo using male Wistar rats and in vitro using rat liver mitochondria.
Twelve hr after intubation with [1,3-14C] MA, 60–70%, 5–15% and 9–17% of administered radioactivity was recovered in expired CO2, feces and urine, respectively. In rats intubated with [1,2-14C] acetate, the corresponding values were 68–82%, 1–2% and 2–3%.14CO2 evolution was initially slower after14C-MA administration than after14C-acetate administration and more radioactivity was excreted in the feces and urine. In vitro experiments using [1,3-14C] MA showed that MA is metabolized primarily in the mitochondria via reactions involving O2 utilization and14CO2 production. The apparent Km and Vmax were 0.5 mM and 9.3 nmol/min/mg protein for O2 uptake, respectively, and 2.0 mM and 2.4 nmol/min/mg protein for14CO2 production. Addition of malonic acid to mitochondrial incubates at concentrations inhibitory to succinate dehydrogenase did
not affect MA-induced O2 uptake but enhanced14CO2 production from14C-MA.14C-Acetate appeared to be the major accumulating metabolite in rat liver mitochondrial preparations following a 120-min incubation
with14C-MA. A probable biochemical route for MA metabolism involves oxidation of MA by mitochondrial aldehyde dehydrogenase followed
by decarboxylation to produce CO2 and acetate. 相似文献
