研究发达国家通过调整产业结构降低碳排放强度,对我国实现碳达峰、碳中和目标具有重要的参考意义。本文以主要发达国家为研究对象,剖析碳排放总量、人均碳排放、碳排放强度、产业结构变化特征,据此获得调整产业结构降低碳排放的经验启示。自 1965 年以来,通过产业转移、科技创新、服务业升级,发达国家普遍形成了“脱钩型”产业结构,即支撑经济增长的同时降低碳排放的产业结构,但同时出现了“制造业空心化”的新问题。针对我国产业结构所处的工业化进程尚未完成、高耗能行业占比较大等现实国情,研究建议积极培育新能源等新兴产业,发挥数字经济在产业结构优化升级中的潜力;坚决防止“制造业空心化”,在确保产业链、供应链安全的前提下,统筹协调国内外产业转移,以此推动产业空间布局优化并促进新发展格局形成。

Exogenic electric fields can effectively accelerate bone healing and remodeling through the enhanced migration of bone marrow mesenchymal stem cells (BMSCs) toward the injured area. This study aimed to determine the following: (1) the direction of rat BMSC (rBMSC) migration upon exposure to a direct current electric field (DCEF), (2) the optimal DCEF intensity and duration, and (3) the possible regulatory role of SDF-1/CXCR4 axis in rBMSC migration as induced by DCEF. Results showed that rBMSCs migrated to the positive electrode of the DCEF, and that the DCEF of 200 mV/mm for 4 h was found to be optimal in enhancing rBMSC migration. This DCEF strength and duration also upregulated the expression of osteoblastic genes, including ALP and OCN, and upregulated the expression of ALP and Runx2 proteins. Moreover, when CXCR4 was inhibited, rBMSC migration due to DCEF was partially blocked. These findings indicated that DCEF can effectively induce rBMSC migration. A DCEF of 200 mV/mm for 4 h was recommended because of its ability to promote rBMSC migration, proliferation, and osteogenic differentiation. The SDF-1/CXCR4 signaling pathway may play an important role in regulating the DCEF-induced migration of rBMSCs.
关键词: DCEF migration osteogenesis differentiation rBMSCs SDF-1/CXCR-4

根据太阳电池直流模型和最大功率点数学条件,推出短路电流、开路电压、最大功率点电流和电压 以及填充因子随日照强度变化的数学关系式;并选取2个电池分别计算出在不同日照强度下上述电池参数随日 照强度的变化率。验证了短路电流和最大功率点电流是近似跟日照强度成正比,开路电压和最大功率点电压是 近似跟日照强度的自然对数成正比。并提出了填充因子随日照强度的变化关系不具有简单的函数形式,而对不 同的太阳电池其变化关系也迥异。最后用Multisim的模拟结果检验了理论分析计算的正确性。
