- Abstract: The modified acrylic super absorbent resin was prepared by aqueous solution polymerization with 2-acrylamide-2-methyl-1-propane sulfonic acid (AMPS) and carboxymethyl cellulose (CMC) containing strong hydrophilic and salt tolerant groups as modifiers. the absorption ratio of the prepared resin in deionized water and normal saline increased from 1496 g/g and 129 g/g before modification to 2944 g/g and 275g / g respectively, and the absorption ratio of soil leaching solution was 267.3 g/g. At the same time, the study on the application of the water absorbent resin in the planting of legumes found that the soil using the modified water absorbent resin can improve the germination rate of mung beans and soybeans and prolong its survival time. After 20 days of soil burial, the water absorbent resin can be degraded. At 38 ℃ , the modified acrylic resin can be degraded by 76% under the action of cellulase for 6 hours. It can be seen that the modification improves the liquid absorption capacity, salt resistance and degradation performance of acrylic water absorbent resin. As a soil water retaining agent, the water absorbent resin can improve the soil environment, save agricultural water and help agricultural development. It has important social value and environmental significance.本文以含有强亲水和耐盐基团的2-丙烯酰胺基-2-甲基-1-丙烷磺酸（AMPS）和羧甲基纤维素（CMC）为改性剂，采用水溶液聚合法，制备了改性丙烯酸高吸水树脂，其在去离子水和生理盐水中的吸液倍率分别从改性前的1496g/g和129g/g提高到2944g/g和275g/g，对土壤浸出液的吸收倍率为267.3g/g。同时，该吸水树脂用于豆类植物的种植研究发现，使用改性吸水树脂的土壤能提高绿豆发芽率，并且延长它的存活时间，土埋20天后，该吸水树脂能降解，在38℃，纤维素酶作用6h，改性丙烯酸树脂降解76%。由此可见，改性提高了丙烯酸吸水树脂的吸液能力、耐盐性能和降解性能，该吸水树脂作为土壤保水剂使用，能改良土壤环境，节约农业用水，帮助农业发展，具有重要的社会价值和环境意义。

- Abstract: Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children and adolescents. Painting therapy is a non-verbal psychotherapeutic method, which can improve the attention, impulse control and emotion management ability of children with ADHD, and relieve anxiety. This article reviews the relevant studies in China and discuss the current status and shortcomings of the application of Painting therapy in the treatment of children with ADHD, with the aim of providing more effective therapeutic references for clinical practice. This study found that painting therapy has significant therapeutic effects in the treatment of children with ADHD, and its efficacy is even better when combined with other treatments. However, there is limited research on the improvement of emotional and social functions in ADHD through painting therapy. This study identified the shortcomings of current research: there are few empirical studies on painting therapy in ADHD, and most existing studies are case studies or small-sample studies, lacking large-sample randomized controlled studies; in the design of painting therapy sessions, there are significant differences in intervention frequency and duration, which should have a direct impact on treatment effectiveness, but this was not clearly stated in the study; the painting content during the intervention process shows consistency, lacking differentiation.注意缺陷多动障碍（attentiondeficithyperactivitydisorder，ADHD）是一种常见的儿童青少年神经发育障碍。绘画治疗是一种非言语心理治疗方法，可以提高ADHD患儿注意力、控制冲动和情绪管理能力，缓解焦虑情绪。本文通过回顾国内相关研究，探讨绘画治疗在ADHD患儿治疗中应用现状及存在的不足，旨在为临床实践提供更为有效的治疗参考。本研究发现绘画治疗在ADHD患儿治疗中具有显著的疗效，与其他治疗联合进行治疗效果更好，绘画治疗对于ADHD的情绪和社会功能改善研究较少。本研究发现当前研究的不足：绘画治疗在ADHD中的实证研究较少，现有研究大多是以个案或者小样本研究为主，缺乏大样本的随机对照研究；在绘画治疗疗程设计上，干预频率、时长差异巨大，这对于治疗效果应该有直接影响，在研究中没有明确说明；干预过程中绘画内容呈现出一致性，缺乏差异化。

- Abstract: Children’s sociality is a key link in the comprehensive development of children, and has been concerned by many scholars in the field of education. Through the distribution of questionnaires to collect data, and with the help of SPSS26.0 to analyze the data, from different dimensions to understand the current situation of children’s social development in urban areas, the survey results show that: (1) There are certain differences in the development level of children’s sociality in each dimension. Among them, the average score of the dimension of living habits was 12.5, which was the lowest development level among the 15 dimensions. The average scores of honesty and justice, empathy and helping others were 16.39 and 16.26, respectively, the highest level of development among the 15 dimensions. (2) There were significant differences in the overall level of social development of children of different genders (p<0.05), and the social development level of female children was higher than that of male children. (3) There was no significant difference in the social development of children of different ages (p>0.05), but there were significant differences in the five dimensions of introversion, self-concept, independence, competitiveness and self-esteem (p<0.05). (4) The overall level of social development of urban hukou children and rural hukou children was similar, and there were only significant differences in the three dimensions of empathy and helping, competitiveness and self-esteem (p<0.05). (5) There was a significant difference in the overall level of social development between the only child and the non-only child (p<0.05), and the difference in the dimensions of empathy and helping reached an extremely significant level (p<0.01), and the difference in the four dimensions of compliance with social rules, introversion, self-concept and competitiveness reached a significant level (p<0.05). In this regard, through field observation and literature to analyze the factors affecting the social development of children, effective strategies to promote the social development of children in urban areas are proposed from the aspects of parents, kindergartens and society.幼儿社会性是幼儿全面发展中的关键环节，在教育界一直受到诸多学者的关注。本文通过发放调查问卷收集数据，并借助SPSS26.0对数据进行分析，调查结果显示：（1）幼儿社会性在每个维度上的发展水平存在一定差异。其中生活习惯这一维度的得分均值为12.5，在15个维度中发展水平最低；诚实公正、共情和助人维度的得分均值分别为16.39和16.26，在15个维度中发展水平最高。（2）不同性别幼儿社会性发展总体水平存在显著差异（p<0.05），且女性幼儿的社会性发展水平高于男性幼儿的社会性发展水平。（2）不同年龄幼儿社会性发展在总体水平上不存在显著差异（p>0.05），但在内外向性、自我概念、独立性、好胜心以及自尊心五个维度上存在显著差异（p<0.05）。（4）城镇户口幼儿与农村户口幼儿社会性发展总体水平相近，仅在共情和助人、好胜心以及自尊心三个维度上存在显著差异（p<0.05）。（5）独生幼儿与非独生幼儿的社会性发展总体水平存在显著差异（p<0.05），且在共情和助人维度上的差异性达到极其显著水平（p<0.01），在遵守社会规则、内外向性、自我概念、好胜心四个维度上的差异性达到显著性水平（p<0.05）。对此，通过实地观察结合文献分析影响幼儿社会性发展的因素，从家长、幼儿园及社会三方面提出促进城区幼儿社会性发展的有效策略。
