Abstract： In 2020, China has historically eliminated absolute poverty. While improving the well-being of the people, it has also accumulated valuable experience in poverty governance. Standing at a new historical starting point, it is necessary to analysis the practice of poverty alleviation in China, and at the same time review the multi-dimensional social changes in the poverty-stricken rural areas of our country. In order to tap the important experience in the practice of poverty alleviation in China, this study first combs the evolution characteristics of China’s poverty alleviation policies from both horizontal and vertical levels, quantitatively analyzes poverty alleviation policies from two aspects of policy density and policy intensity, and calculates the cumulative effectiveness of China’s poverty alleviation policies. Finally, selecting a number of indicators that can be measure the multi-dimensional changes in rural society to analyze the correlation between the multi-dimensional changes in rural society and the cumulative effectiveness of poverty alleviation policies. The study found that the cumulative effectiveness of poverty alleviation policies has a significant negative correlation with the incidence of poverty in rural areas, and a significant positive correlation with infrastructure construction conditions, the level of social public services, and the living standards of residents in poor rural areas.

Abstract：气体绝缘输电管道（GIL）绝缘子通常由环氧树脂 /Al2O3 复合材料浇注而成。在直流电压及负载温升作用下，绝缘子表面易积聚电荷造成电场畸变，进而引发沿面闪络。本文为探索非线性 ZnO 填料对环氧树脂 /Al2O3/ZnO 复合材料绝缘性能的影响规律，对直流电压下不同 ZnO 含量的环氧复合材料表面电位衰减进行了测量，分析了不同温度对表面电荷特性的影响，得到了基于电荷消散的非线性电导变化规律。研究结果表明：直流电压下，ZnO 颗粒掺杂可以明显促进环氧复合材料表面电荷消散；随着温度升高，载流子迁移率增大，表面电荷的消散速度加快；当 ZnO 含量超过一定阈值时，电导率在高场下呈现非线性特性，从而抑制环氧树脂复合材料表面电荷积聚。相关结果为非线性电导复合材料在调控直流气体绝缘输电管道绝缘子表面电荷特性方面的应用提供了参考。

Abstract：丁酸梭菌（Clostridium butyricum）具有调节肠道微生态平衡、产生消化酶和维生素等营养物质、提高动物免疫力、抗细胞凋亡、抗肿瘤等多种生理功能。此外，丁酸梭菌属于厌氧芽孢杆菌，对饲料加工过程中的高温、高压以及动物胃肠道环境有较好的耐受性。因此，丁酸梭菌是一种适合在畜禽生产中添加的益生菌。本文总结了丁酸梭菌的生物学特性、生理功能和对畜禽生产的影响及其作用机理，为丁酸梭菌的进一步研究和开发应用提供参考。
