Learning Chinese in a study abroad context: The case of ritual congratulating

open access: yesInternational Journal of Applied Linguistics, Volume 33, Issue 3, Page 459-475, November 2023., 2023
Abstract In this paper, we explore how and why the realisation of the ritual act of congratulating may turn out to be challenging for foreign learners of Chinese. Congratulating and other ceremonial ritual acts are not only used when someone participates in an actual ritual event: they are also required when they are mentioned in mundane events, like ...

Early incisor lesions and Equine Odontoclastic Tooth Resorption and Hypercementosis: Reliability of radiographic findings

open access: yesEquine Veterinary Journal, Volume 55, Issue 2, Page 261-269, March 2023., 2023
Summary Background In clinical practice, early diagnosis of Equine Odontoclastic Tooth Resorption and Hypercementosis (EOTRH) and other resorptive incisor diseases is difficult to achieve. The radiographic appearance of subtle pathological changes has not been described in detail and might be confused with age‐related changes.

500kV直流断路器快速机械开关典型故障特性及可靠性提升方法研究 [PDF]

open access: yes, 2023
直流断路器是构建柔性直流电网不可或缺的关键设备。快速机械开关是直流断路器中承载电流、实现快速分合闸、耐受分闸恢复电压的核心组件,其结构复杂、动作速度快、电气应力严酷、可靠性要求高,因而设计研制难度大,任一环节出现问题均会影响直流断路器乃至柔直电网的安全可靠运行。然而,目前快速机械开关由于存在设计选型不合理、工艺管控不严格、试验考核不完善等问题,导致在实际工程应用中故障率较高。针对已应用于张北柔性直流电网试验示范工程的500 kV直流断路器,分析了直流断路器研制、调试 ...

In vitro killing of canine strains of Staphylococcus pseudintermedius and Escherichia coli by cefazolin, cefovecin, doxycycline and pradofloxacin over a range of bacterial densities

open access: yesVeterinary Dermatology, Volume 31, Issue 3, Page 187-e39, June 2020., 2020
Background Bacterial densities likely fluctuate during infection and may exceed the bacterial density used in susceptibility testing. As such, investigation of bacterial killing by antibiotics over a range of varying bacterial densities may provide important differences between compounds and could impact drug selection for therapy.

A Technology and Application of Fiber Temperature Sensor for High Voltage Circuit Breaker [PDF]

open access: yes, 2015
随着中国经济的高速发展,电网规模的日益庞大,高压断路器作为电力系统中必不可少的电气设备之一,其工作状态是否正常关乎整个电力系统能否安全高效地运行。为了避免高压断路器因电阻过大或其他故障引起的局部温度超过国家标准而引发停电、火灾等大规模事故,对高压断路器的温度进行实时监测是十分必要的。 针对10KV断路器在线温度监测难的问题,本文提出一种基于反射式强度调制的光纤温度传感系统。本温度传感系统具有非接触、抗电磁干扰能力强、安装便利、性能稳定等优点,此外,本文选用双金属片作为温度敏感元件,价格低廉 ...

Research on digital discretion—The subjectification of street‐level work in public administration

open access: yesReview of Policy Research, Volume 42, Issue 1, Page 122-148, January 2025.
Abstract The article presents a systematic review of scholarly articles (n = 168) focused on digital discretion—how digital technologies affect the discretionary autonomy of street‐level bureaucrats. Two analytical tasks are performed concerning how digital transformation has affected (1) the relations between top‐down governing and the work of street ...

Design and Simulation of Contact Fatigue Testing System of Flexspline and Circular Spline in Harmonic Drive [PDF]

open access: yes, 2016
谐波齿轮传动是随着空间技术的发展而诞生的一种新型传动方式,其工作原理是利用柔轮的弹性变形波来实现运动或者动力传递,因其具有结构简单、传动精度高、传动比大等诸多优点,在航空、航天、机器人等领域得到了广泛应用。在谐波齿轮传动过程中,柔轮的运动情况比较复杂,作为弹性薄壁构件需承载交变应力,容易造成齿面磨损和疲劳断裂。因此,建立合适的模型对谐波齿轮传动过程中柔轮的错齿运动进行模拟分析具有重要意义。 本文首先针对谐波齿轮传动过程中柔轮的错齿运动设计了一种新的接触疲劳试验装置 ...
