Discussion on the Improvement of the Reliability of Electromagnetic Relay [PDF]
, 2016 电磁继电器作为一种自动控制电气开关，广泛运用于各种控制电路中。当给予一个较小的信号输入量，如电、磁、光、热等信号时，它能够使被控制的电路实现自动切换。电磁继电器同时也是一种失效率较高的电子元器件，因其导致整机可靠性水平较低的问题历来受到广泛重视，如何提升继电器的可靠性是继电器制造企业一个非常重要的课题。尽管继电器是最早被用于可靠性研究的电子元器件，但由于历史原因，其研究对象主要限定在应用于航天航空领域的密封继电器，而那些应用于家电类继电器，因属于民用功率继电器，且价值相对较低，其可靠性研究被关注的较少 ...

Implications of Tobacco Use on Pathogen‐Driven Diseases: A Public Health and Policy Perspective
World Medical &Health Policy, Volume 17, Issue 3, Page 468-474, September 2025.ABSTRACT The tobacco epidemic remains one of the most significant global public health challenges, responsible for over 8 million deaths annually, with a substantial portion occurring among non‐smokers exposed to second‐hand smoke. While cigarette smoking remains the most prevalent form of tobacco use worldwide, the rise of electronic nicotine delivery

Return from exile: Mythology and heritage in American Born Chinese and its Disney adaptation
Popular Culture Review, Volume 35, Issue 2, Page 228-237, Fall 2024.Abstract Though American Born Chinese has received a significant degree of scholarly study, the prevalence of cultural exile in the text has not received sufficient attention. Said's theorization on exile provides a guide to examining the mindset of Jin, who willfully accepts exile from his Chinese‐American heritage because of how he feels neither ...
