光纤紧套被覆层剥离力的试验研究

open access: yesGuangtongxin yanjiu, 2012
光纤紧套被覆层剥离力是体现产品质量的一项重要指标。由于前期缺乏试验数据的积累,在相关标准中未对这一指标做出明确规定。文章对光纤紧套层剥离力进行了试验性研究,试验发现由于紧套光纤的被覆层较厚,易出现"塞积"效应。"塞积"效应对判断紧套光纤剥离力的大小有重要的影响,而它本身与试验时的刀具移动距离、移动速率及总剥离长度等因素有关,这些结论对科学规范紧套层剥离力的有效范围提供了重要的科学试验依据,同时可作为开展下一步研究工作的基础。

Savoring interventions for mothers of young children: Mechanisms linking relational savoring and personal savoring to reflective functioning

open access: yesInfant Mental Health Journal: Infancy and Early Childhood, Volume 44, Issue 2, Page 200-217, March 2023., 2023
Abstract Parenting interventions can improve parenting outcomes, with widespread implications for children's developmental trajectories. Relational savoring (RS) is a brief attachment‐based intervention with high potential for dissemination. Here we examine data from a recent intervention trial in order to isolate the mechanisms by which savoring ...

浅析“三供一业”剥离对国有企业经济效益的影响

open access: yes, 2020
在我国,国有企业是我国国民经济的命脉,对我国社会经济的发展做出了突出的贡献,但是长期受计划经济的影响以及历史遗留问题,国有企业背负着“三供一业”巨大的经济负担,使得发展缓慢,企业改革困难,从而国有企业在与同行业竞争中处于劣势地位。为了促进国有企业的发展,我国计划推行剥离“三供一业”的政策,为国企减负。

试析水土保持方案编制中的表土剥离问题

open access: yes水电水利, 2019
表土剥离在编制水土保持方案中是必须考虑的内容,其直接影响了水土保持方案编制的质量,所以人们也格外重视表土剥离。但在水土保持方案编制的过程中,表土剥离依然存在着一定的不足,仍需要采取有效措以完善表土剥离。

International clinical practice recommendations on the definition, diagnosis, assessment, intervention, and psychosocial aspects of developmental coordination disorder – Chinese (Mandarin) translation

open access: yesDevelopmental Medicine &Child Neurology, Volume 61, Issue 3, Page E1-E35, March 2019., 2019
目的 本国际临床指南由欧洲残疾儿童学会(the European Academy of Childhood Disability,EACD)牵头制定,旨在解决发育性协调障碍(developmental coordination disorder,DCD)的定义、诊断、评估、干预以及与社会心理方面的临床应用关键问题。 方法 本指南针对五个领域的关键问题,通过文献综述和专家团队的正式讨论达成共识。为保证指南的循证基础,以“机制”、“评估”和“干预”为检索词, 对2012年更新以来提出的最新建议以及新增的“社会心理问题”和“青少年/成人”为检索词进行检索。根据牛津大学循证医学中心证据等级 (证据水平 [level of evidence, LOE]1–4) 将结果进行分类,最终转化为指南建议。并由国际 ...

Assessing D‐Squame as a Minimally Invasive Technique to Evaluate the Cutaneous Immune Response mRNA in a Dog Model of Canine Atopic Dermatitis

open access: yesVeterinary Dermatology, Volume 37, Issue 3, Page 353-364, June 2026.
ABSTRACT Background Canine atopic dermatitis (cAD) is a multifactorial, inherited skin disease, estimated to affect ≤ 15% of dogs. Studies of skin messenger mRNA in cAD currently use invasive methods, including blood sampling and biopsy collection, whilst advances in human atopic dermatitis study methodology have demonstrated reliable use of minimally ...

电解参数对循环冷却水处理及倒极除垢效果的影响

open access: yesGongye shui chuli, 2020
利用电化学法处理循环冷却水,探究电解参数对处理效果的影响,并探究不同倒极条件对阴极结垢的剥离效果和剥离方式。结果表明,当水质硬度为800 mg/L、Cl-质量浓度为567.2 mg/L、电流密度为10 mA/cm2、水力停留时间为10 min时,硬度去除质量浓度为300 mg/L,Cl-去除质量浓度为140 mg/L,活性氯质量浓度为8.74 mg/L,电流效率为88.44%;在除垢时间为8 min,倒极电流密度为5 mA/cm2的条件下,阴极结垢剥离率达到了94.3%,以物理脱落为主 ...

火灾下膨胀型钢结构防火涂层的破损及其对钢构件升温过程的影响

open access: yesJianzhu Gangjiegou Jinzhan, 2021
为考察火灾下膨胀型钢结构防火涂层破损模式与程度的影响因素和涂层破损对钢构件温升过程的影响,对钢构件表面涂覆防火涂层组成的试件进行隔热性能试验和标准耐火试验。试验过程中测量并记录钢构件温度,试验结束后统计分析涂层的破损情况。研究结果表明,火灾下膨胀型钢结构防火涂层的破损模式为开裂和界面剥离,涂层脱落发生在降温过程。无荷载板型和短柱试件涂层的破损模式为Ⅰ型细小裂纹和Ⅱ型小裂缝,钢基材截面最大温差与截面平均温度的比值分别小于2.2%和6.3%。轴压长柱试件涂层的破损模式为Ⅲ型与Ⅳ型大裂缝(基材为碳钢 ...

Interfacial Engineering of Sodiophilic Metal Layers on Liquid Alloys for Dendrite‐Free Sodium Metal Anodes

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT Sodium metal batteries hold significant promise for large‐scale energy storage due to the high theoretical capacity and abundant sodium sources, yet sodium‐metal anodes are hindered by dendrite propagation, unstable solid electrolyte interphase, and poor cycling efficiency arising from uneven Na deposition and volume changes.
