超声诊断干燥综合征颌下腺病变研究进展
Progress in Ultrasonic Diagnosis of Submandibular Adenopathy in Sjogren’s Syndrome  [PDF]
易文娟, 张玉英
Advances in Clinical Medicine (ACM) , 2021, DOI: 10.12677/ACM.2021.118499
Abstract: 干燥综合征(Sjogren syndrome, SS)是一种发病率较高的慢性炎症性自身免疫性疾病，主要影响以淋巴细胞渗透为特征的颌下腺、泪腺等，导致腺体破坏和功能受损。早期诊断SS对于疾病治疗有着重要作用。因此，我们对超声检查在干燥综合征颌下腺病变方面的实际应用进行综述。
Sjogren’s syndrome (SS) is a chronic inflammatory autoimmune disease with a high incidence, which mainly affects the submandibular glands and tear glands characterized by lymphocyte infiltration, leading to gland damage and impaired function. Early diagnosis of SS plays an important role in disease treatment. Therefore, we review the practical application of ultrasound to the submandibular adenopathy of SS.
企业环境治理影响因素研究综述
Review on Influencing Factors of Enterprise Environmental Governance  [PDF]
张玉娟, 郭艳平
Advances in Social Sciences (ASS) , 2022, DOI: 10.12677/ASS.2022.111046
Abstract: 十九届六中全会强调高质量发展是生态优先绿色发展，企业作为污染物排放的主体，是绿色发展中环境治理的关键环节，剖析企业环境治理的影响因素，是实现绿色低碳发展，助推高质量发展的重要内容。现有文献主要从正式制度和非正式制度角度探讨企业环境治理的影响因素，也有部分文献着重分析了机构投资者在企业环境治理中所起的作用。通过对已有研究文献的梳理，以期为完善企业环境治理提供经验证据，为助推生态文明建设提供政策依据。
The Sixth Plenary Session of the 19th CPC Central Committee stressed that high-quality develop-ment is ecological priority and green development. As the main body of pollutant emission, enterprises are the key link of environmental governance in green development. Analyzing the influencing factors of enterprise environmental governance is an important content to realize green and low-carbon development and boost high-quality development. The existing literature mainly discusses the influencing factors of enterprise environmental governance from the perspective of formal system and informal system. Some literatures also focus on the role of institutional investors in corporate environmental governance. Through combing the existing research literature, we hope to provide empirical evidence for improving enterprise environmental governance and provide policy basis for promoting the construction of ecological civilization.
大学生外卖消费行为研究——以宁夏大学学生为例
College Students’ Consumption Behavior—A Case Study on Students in Ningxia University  [PDF]
马玉娟, 康娟, 张建, 郑芳
Sustainable Development (SD) , 2019, DOI: 10.12677/SD.2019.94092
Abstract:

随着经济发展，互联网与交通演进，高校学生的外卖消费日趋增加，外卖消费为大学生带来便捷、多样化体验，同时，由于外卖行业牵涉面广，部分环节出现了一些问题，如食品安全，环境破坏等。该论文以宁夏大学本部学生为研究对象，基于其外卖消费行为调查数据，对宁夏大学周边外卖环境优化进行了思考。未来外卖环境优化中需实现品种多样化、餐食及服务质量提升、价格合理。另外对服务人员自身素质及城市交通进行优化完善。
With economical development, and evolution of the Internet and transport, college students are spending more and more on take-out consumption. Take-out consumption brings convenient and diversified experience. Due to wide involvement of the take-out field, some problems have ap-peared in some intermediate links, such as food safety and environmental damage. This study takes the students in Ningxia University as the research objects based on survey and questionnaire of students’ take-out consumption behavior to optimize the take-out environment around Ningxia University. In order to optimize the take-out environment in the future and diversify varieties, improved food and service quality and reasonable price should be realized. In addition, the quality of service personnel and urban traffic is optimized and improved.

叙述形式的人文价值——《索菲的选择》的叙事结构分析
张玉娟
浙江大学学报(人文社会科学版) , 2001,
Abstract: ？结构主义批评、叙述学理论往往局限于对作品形式的研究，而未能对作品进行价值判断。文学批评的出路应使文本研究和审美价值判断相结合，形式研究与内容研究相结合。小说《索菲的选择》中对聚焦、时空、场所等结构因素的安排，综合运用了现代小说与传统小说的技法。这虽然使作品历史的明晰性有所减弱，但却增强了作品的情感力度，有利于表现人与社会的紧张关系，从而将生活提高到哲理的层面上进行思考，真正达到了艺术创造中对结构因素的最高要求——“有意味的形式”。
ta_2o_5mgo对超纯al_2o_2瓷显微结构和力学性能的影响
张玉娟
武汉理工大学学报 , 1983,
Abstract: ？本文研究了少量ta_2o_5、mgo对超纯al_2o_3瓷的烧结及显微结构和力学性能的影响。用金相显微镜、扫描电子显微镜(sem)和透射电子显微镜(tem)研究了试样的微观结构及断裂表面。发现少量ta_2o_5的加入能有效地促使al_2o_3瓷的烧结,其作用比mgo显著。空气介质中较低温度就能将加ta_2o_5的试样烧结至98％理论密度。ta_2o_5的加入能明显降低超纯al_2o_3瓷的烧成温度,还使瓷件强度有所提高。比较二种添加剂对超纯al_2o_3瓷烧结性能和显微结构的影响,笔者认为ta_2o_5、mgo作为超纯al_2o_3的添加剂时,各有其主要作用机埋。提出了ta_2o_5的固溶体机理,认为ta_2o_5主要是固溶到al_2o_5晶格中,使晶体中产生“组成缺陷”,从而使扩散系数dv增大、烧结致密化速率加快。还发现ta_2o_5的加入量存在最佳值。而mgo主要是富集在晶界,起抑制晶粒生长作用。在超纯al_2o_3中同时加入适量的ta_2o_5和mgo。充分发挥二者的主要作用机理在较低温度下就能将试样烧结至理论密度。超纯al_2o_3瓷的强度不仅与试样的平均晶粒尺寸有关,晶粒大小分布,晶粒间堆积结构同样是影响试样强度值的灵敏因素。用扫描电镜对试样断面研究结果表明:室温下,超纯al_2o_3瓷试样以沿晶断裂为主,随着晶粒尺寸增大,试样中的穿晶断裂量逐渐增多。穿晶断裂并不是沿某一结晶学平面发生,而是呈台阶形、螺旋形断裂。这种现象在外加0.5％ta_2o_5的c试样中尤其明显,这可能与固溶进去的杂质的存在有关。

Based on the PM2.5 mass concentration and meteorological data of Wusu city from 2016 to 2018, the distribution characteristics of PM2.5 concentration and its correlation with meteorological elements were analyzed by using conventional statistics, Pearson correlation analysis and t-test analysis. The results showed that the daily variation curve of PM2.5 mass concentration in Wusu city was unimodal, and the high value area of PM2.5 mass concentration appeared at 13:00 - 23:00, and the peak appeared at 15:00. The air pollution was the most serious in January; PM2.5 concentration showed a certain seasonal characteristics; winter > autumn > spring > summer; winter pollution days accounted for 75% of the whole year; winter air pollution reached moderate pollution level; PM2.5 mass concentration in Wusu city was negatively correlated with temperature, precipitation, average wind speed, maximum wind speed and sunshine, and positively correlated with relative humidity and air pressure.

水杨酸对梨sod、ppo同工酶和npr1表达的影响
高丽娟,张玉星
园艺学报 , 2013,
Abstract: 以鸭梨（pyrusbretschneideri‘yali’）为试材，研究外源水杨酸处理后梨叶片中内源水杨酸（sa）及超氧化物歧化酶（sod）、多酚氧化酶（ppo）同工酶的变化特点以及病程相关基因非表达子1（npr1）对水杨酸的早期应答反应。结果表明：水杨酸处理后梨叶片中内源sa含量升高，其中游离态sa含量随处理浓度增大而逐渐升高，但均显著低于对照；结合态sa随处理增大而逐渐降低，但均显著高于对照。sod、ppo同工酶酶谱分析结果显示，水杨酸处理后酶谱带表达量增强。接种病菌试验表明，0.200mmol·l-1sa可以诱导梨增强对轮纹病的抗性，且诱导处理过的叶片受到病菌侵染时sod、ppo酶活性增强。实时荧光定量pcr分析表明，0.200mmol·l-1sa诱导后梨叶片中npr1表达量明显升高，但npr1在茎中的表达受到抑制。
