Posttraumatic Growth After MDMA‐Assisted Psychotherapy for Posttraumatic Stress Disorder
Journal of Traumatic Stress, Volume 33, Issue 2, Page 161-170, April 2020., 2020 Abstract 3,4‐Methylenedioxymethamphetamine (MDMA)–assisted psychotherapy for posttraumatic stress disorder (PTSD) has been shown to significantly reduce clinical symptomatology, but posttraumatic growth (PTG), which consists of positive changes in self‐perception, interpersonal relationships, or philosophy of life, has not been studied with this ...

Rare Metals, EarlyView.ABSTRACT The limited osteogenic capacity of magnesium phosphate cement (MPC) has constrained its biomedical applications, underscoring the necessity to develop MPC with enhanced physical properties and bone‐forming capabilities. In this study, a multifunctional MPC system was developed by incorporating zoledronic acid‐loaded near‐infrared (NIR ...

Conservation Biology, EarlyView.Abstract The design of experiments to investigate the combined effects of multiple stressors requires exposing target organisms to multiple combinations of stressor doses. Concurrent manipulation of stressors is often infeasible with wildlife, but long‐lasting health effects allow individual health to be used as an integrator of prior stressor exposure.

智能城市应用现代人们的经济水平显著提高，对于生活各项设施的质量要求也随之提升。水是人们生活当中的必须资源，净水机的应用能够净化自来水质，但是一些净水机在运行时增压泵的存在比较大的噪声，影响着净水机使用的体验舒适感。基于此，文中就对净水机用增压泵的噪声分析及降噪技术分析，先对反渗透净水机增压泵运行的噪声进行测试分析，然后针对噪声的实际情况提出改善技术措施。

Dianci bileiqi, 2014 利用Obenaus模型对复合绝缘子的闪络特性进行分析,以现场运行年限不同的试品在不同喷水电导率下进行闪络试验,试验结果表明:同一试品闪络电压随着喷水电导率的增加呈指数规律下降,但憎水性差的试品变化规律不够明显。通过试验及模型计算,得出电弧总的阴阳极压降和憎水性存在一定关系,其数值大小随着憎水性能的减弱而减小。研究结果表明:憎水性是影响复合绝缘子闪络电压的主要因素,它是通过决定电弧总的阴阳极压降的大小来影响闪络电压的数值;闪络电压还受水带电导率的影响,电导率取决于绝缘子表面的积污程度。

Gaoya dianqi, 2022 复合绝缘子是电网中的关键设备，在高湿高热的南方环境中，水分容易侵入复合绝缘子，有可能导致温升、机械破坏的事故发生。为研究湿热环境下水分侵入绝缘子压接界面的侵入路径，文中选取退役的复合绝缘子进行水煮试验和浸泡试验，并用傅里叶红外光谱、X射线光电子能谱、扫描电镜和EDS元素分析等工具分析了未经处理的绝缘子高压端密封胶试样和经过处理的绝缘子低压端密封胶试样在空气界面、护套界面、金具界面上的老化程度。通过试验得出结论：密封胶护套试样在实际运行的过程中会和护套发生交联反应 ...

Gaoya dianqi, 2013 气体绝缘开关柜通常采用内锥或外锥套管作为绝缘水平试验时的高压引入接口。目前常用的高压引入装置为高压试验电缆,环氧绝缘内锥高压适配器。提出了一种新型的硅橡胶绝缘高压适配器设计,适用于各种C-GIS或其他气体绝缘开关设备的绝缘水平试验用高压引入接口。该设计结构简单、制造成本低、安装快捷方便,已广泛应用于气体绝缘开关设备的工厂出厂试验、现场交接试验等需要高压引入的场合。
