王玉琼, 解长江
Creative Education Studies (CES) , 2019, DOI: 10.12677/CES.2019.74089
Abstract:
从对分课堂理论介绍和课程改革实施方案入手，探求在高职英语教学中实施对分课堂的理路设定与模式建构；结合实证研究、问卷调查和访谈等方法，探究学生在课后学习、课堂讨论、学习效果三个维度上的看法及在班级中践行的情况，验证高职类学生对分课堂英语课程的教学效果。研究结果表明：学习效果是学生最重视，实践程度最高的部分；实验组学生比对照组学生考试成绩有显著提高，对分课堂效果明显，为高职英语教学改革提供新的视角。

解妍琼,张莹,杜丹
空间科学学报 , 2014, DOI: 10.11728/cjss2014.01.011
Abstract: 选取第23太阳活动周（1997—2006年）期间542例由太阳爆发活动驱动的行星际激波事件，分析确定了太阳源头和行星际空间中影响行星际激波能否到达地球轨道的关键物理参数；在此基础上，建立了预测行星际激波能否到达地球的新预报模型（EdEaSPM）.回溯预报结果表明，EdEaSPM模型的预报成功率约为66%，略高于国际一流预报模型的预报成功率；EdEaSPM模型的虚报率未超过50%，改善了当前国际主流模型虚报率较大的情况；对于偏度指标，虽然当前所有模型的偏度值均大于1，但EdEaSPM模型的偏度值最接近于1且明显小于其他模型的偏度值；EdEaSPM模型的其他评价指标也都高于国际主流模型的相应指标.此外，选取2012年期间的激波事件对EdEaSPM模型进行了预报检验，预测结果与实际情况吻合.EdEaSPM模型不仅能够提前约1～3天进行预报，而且预报效果与国际一流模型具有可比性，尤其是在提高预报成功率及降低虚报率方面具有一定优势.
12Cr2Ni4A滑油附件主动轴螺纹根部裂纹分析
全琼蕊, 解菁,谢善

Abstract: 摘要 航空发动机在大修时发现12Cr2Ni4A滑油附件主动轴轴头螺纹根部有裂纹显示。采用化学成分、金相、断口分析以及硬度检测等手段对裂纹产生原因进行分析。结果表明：裂纹为过大螺母预紧力产生的应力裂纹，但螺纹部位的加工设计不当加剧了裂纹的产生，例如螺纹根部存在氰化层降低了材料的断裂韧度；止动槽与螺纹交界处未倒圆易形成应力集中；止动槽上部宽底部窄，导致垫圈内锁片挤压U型槽底部产生挤压变形。为避免此类故障的发生，提出相应的改进措施：使用限力扳手控制螺母不要过度预紧，对不需要氰化的螺纹部位采取遮蔽的方式，对止动槽与螺纹转接处处进行适当倒圆

东北大学学报:自然科学版 , 2015, DOI: 10.3969/j.issn.1005-3026.2015.01.009
Abstract: 利用电化学工作站，结合微观腐蚀形貌分析，研究了铁素体不锈钢在盐酸溶液中的腐蚀过程.结果表明:铁素体不锈钢在盐酸溶液中的腐蚀过程分为3个阶段:表面钝化膜的穿透、腐蚀产物膜的增厚以及阴阳极反应平衡.不锈钢在表面钝化膜的穿透和腐蚀产物膜的增厚阶段仅发生均匀腐蚀，而在反应平衡阶段不锈钢表面出现大量的晶间腐蚀和少量的点蚀.当盐酸质量分数大于10%时，铁素体不锈钢在盐酸溶液中的极化曲线钝化区完全消失，其腐蚀过程主要受阳极控制.随着盐酸质量分数的增大，溶液电阻Rs和电极反应的电荷转移电阻Rt均逐渐减小，同时腐蚀电极表面双电层结构中的充放电能力不发生改变.

Abstract: 川气东送管道站场、阀室大量采用一体式焊接截止阀作为压力或气体取样的根部接口阀,自投产以来,多次发生阀杆微漏,若处理不及时,持续泄漏会造成爆炸、火灾等安全事故.根据川气东送管道站场的泄漏状况,在投产初期采用更换阀门方法不可取的情况下,采取不停输带压堵漏技术.通过对现场泄漏状况的勘查,进行专用夹具的设计、制造,并在实验室内模拟现场压力表根阀泄漏后的带压堵漏治理,取得了良好效果.经现场实际应用,成功解决了困扰输气生产过程中一体式焊接截止阀阀杆泄漏的难题
儒商的人际关系营销之道
The Interpersonal Relationship Marketing of Confucian Businessman  [PDF]
解冬冬
Modern Marketing (MOM) , 2015, DOI: 10.12677/MOM.2015.54009
Abstract:
儒商一词最早现于二十世纪后的南洋华商之中，但儒商却古已有之，陶朱公、子贡等人，皆是古代儒商的代表。儒商被定义为受中国儒家文化影响的，拥有较高道德品质与文化素养的成功商人。儒商即收获了成功的事业，也受到了人们的尊重，其成功的原因正是儒商所遵循的人际关系营销之道。儒商的经营之道已经远远的超出了经济范畴，他们的营销之道也更加值得探究。
The word of Confucian businessman first appeared in twentieth century because of the Nanyang Chinese. But Tao Zhugong, Zi Gong etc. are all the representative of the ancient Confucian busi-nessman who arose before twentieth century. Confucian businessman is defined as Chinese people who are influenced by Confucian culture, as a successful businessman with high moral quality and cultural accomplishment. The Confucian businessmen harvest success and also win the people’s respect. The reason for its success is the interpersonal relationship marketing. The meaning of Confucian marketing has been far beyond the economic category and is more worthy of inquiry.

The Influence of Social Factors on Empathy for Pain  [PDF]
解鸿宇
Advances in Psychology (AP) , 2020, DOI: 10.12677/AP.2020.102024
Abstract:
共情是一个多重概念，可以指一种心理能力或者一种心理状态，通常来讲，共情指个体感知或想象其他个体的情感，并部分体验到其他个体感受的心理过程。疼痛共情是共情研究的重要部分，因为其拥有较好观测，数量化指标明确的优点，并且疼痛共情在现实生活中也具有重大的意义。而疼痛共情的影响因素则是疼痛共情的研究中的核心。疼痛共情会受到多方面因素的影响，一般来讲包括疼痛者因素、观察者因素以及情境因素。而本文则从另一个角度，社会性因素对疼痛共情的影响来进行讨论。本文主要从性别，社会地位，人际距离以及情绪背景对疼痛共情的影响进行了说明和描述，并且简要介绍了其他社会性因素对疼痛共情的影响。在本文的最后，对社会因素性对疼痛共情的影响的未来研究进行了简短的展望，未来的研究应该更加注重研究内容与理论以及实际的结合。
Empathy is a multiple concept, which can refer to a mental ability or a mental state. Generally speaking, empathy refers to the psychological process in which an individual perceives or imagines the feelings of other individuals and partially experiences the feelings of other individuals. Empathy for pain is an important part of empathy research, because it has the advantages of better observation and clear quantitative indicators, and empathy for pain has great significance in real life. The influencing factors of empathy for pain are the core of the research of empathy for pain. Empathy for pain is affected by a number of factors, including the painful person factors, the observer factors, and situational factors in general. This paper discusses the effect of social factors on empathy for pain from another perspective. In this paper, the effects of gender, social status, interpersonal distance and emotional background on empathy for pain are explained and described, and other social factors on empathy for pain are briefly introduced. At the end of this paper, the future research on the influence of social factors on empathy for pain is briefly prospected. The future research should pay more attention to the combination of research content, theory and practice.

Applied Physics (APP) , 2021, DOI: 10.12677/APP.2021.112014
Abstract: 铝合金作为汽车轻量化的主要材料，具有广泛的应用前景，如何准确评价铝合金型材弯曲成型及回弹性能对于工业生产具有重大的应用价值。针对铝合金型材的弯曲回弹，本文采用ABAQUS数值软件进行了有限元模拟，并将模拟结果与实验结果对比分析，验证模拟的可靠性。利用仿真结果获得了型材弯曲回弹时应力、应变的变化情况，给出了阻尼系数与回弹量误差之间的关系。结果表明，回弹前各部位对应的应力、应变值均大于回弹后的，应力、应变最大处基本在同一位置。回弹偏差受到阻尼系数的影响，误差最小在10%，因此数值模拟对实际产品生产有一定指导意义。
As the main material for automobile lightweight, aluminum alloy has a wide range of application prospects. Accurate evaluation of the bending forming and resilience performance of aluminum alloy profiles has great application value for industrial production. Aiming at the bending springback of aluminum alloy profiles, ABAQUS numerical software was used in this paper to carry out finite element simulation, and the simulation results were compared with the experimental results to verify the reliability of the simulation. The simulation results were used to obtain the stress and strain changes of the profile during bending and springback, and the relationship between the damping coefficient and the springback error was given. The results show that the corresponding stress and strain values of each part before springback are larger than those after springback, and the maximum stress and strain are basically at the same position. The springback deviation is affected by the damping coefficient, and the minimum error is 10%. Therefore, numerical simulation has certain guiding significance for actual product production.
