Dianci bileiqi, 2015 为了提高电涌保护器中压敏电阻的耐电流冲击性能,生产上均采取压敏电阻的并联组合。在测试过程中发现,论文中的两种并联结构其8/20μs通流容量相差约20%。对并联组合后的压敏电阻劣化原因进行了分析,认为非对称并联结构的电流不均匀,其中一只压敏电阻承受的电流过大,导致性能迅速劣化、失效。通过加大电极片、连接片的宽度,降低阻抗,减小电流值的偏差,同时采用不同通流容量的压敏电阻进行配对并联,从而提高非对称并联结构的通流容量。

Biodiversity‐driven spatial conservation planning to delineate temporally stable regions
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract The accelerating loss of biodiversity underscores the critical need for effective conservation strategies, particularly in the face of climate change and anthropogenic pressures. We devised a conservation planning framework that adopts a temporal stacking approach to species distribution models and landscape connectivity analyses. These models

Defining and identifying relevant stakeholders to advance effective conservation
Conservation Biology, Volume 40, Issue 3, June 2026.The challenge of defining stakeholders in environmental science and an approach for refining existing definitions. Abstract Stakeholder is a contested term that has spawned a multitude of ad hoc definitions. The ambiguity of these definitions has oftentimes impeded transdisciplinary research in environmental governance and conservation science because ...

A more‐than‐human political ecology of Indonesian songbird trade
Conservation Biology, Volume 40, Issue 3, June 2026.Abstract Since its inception, conservation science has considered wildlife trade a problem. In focusing on conservation outcomes, conservationists almost completely ignore the welfare of traded animals and plants and the harms they endure. We developed a political ecology approach that incorporates the interconnectedness of people with animals and ...
