Use of carrion fly iDNA metabarcoding to monitor invasive and native mammals
Conservation Biology, Volume 37, Issue 5, October 2023., 2023 Abstract Severely fragmented habitats increase the risk of extirpation of native mammal populations through isolation, increased edge effects, and predation. Therefore, monitoring the movement of mammal populations through anthropogenically altered landscapes can inform conservation. We used metabarcoding of invertebrate‐derived DNA (iDNA) from carrion

Dianci bileiqi, 2022 随着动车组服役年限的增加，其车顶绝缘子的绝缘性能会发生衰退。为研究不同服役年限下高压隔离开关用绝缘子性能衰退特性，本研究以动车组车顶复合支柱绝缘子为研究对象，对其进行了憎水性、绝缘电阻测试和雷电冲击试验。基于绝缘子憎水性测试，研究表明，服役年限为3年的绝缘子憎水性最好，为HC3级。与服役年限为3年的绝缘子相比，服役年限为4年、5年、6年和10年的绝缘子憎水性普遍下降，均为HC4-HC5左右；基于绝缘子绝缘电阻测试，研究表明，不同服役年限下绝缘子泄漏电流变化不大，均维持在30.6μA～42.0μA ...

6.3～40.5 kV干燥空气开关柜绝缘件阻燃性的实验分析与研究
Gaoya dianqi, 2020 绝缘件是6.3～40.5 kV空气绝缘开关柜设备中的薄弱环节,其中环氧树脂绝缘件在设备中应用较多,其性能直接决定开关设备的绝缘性能及运行可靠性。环氧绝缘件一般采用双酚A环氧树脂和固化剂经过复杂的化学反应制成,不同制备条件、工艺等对绝缘件的使用性能有很大影响。文中通过不同配比的环氧树脂样品的实验分析和研究,得出了玻璃化转变温度、填料、耐电痕性能等对绝缘件阻燃性的影响,对绝缘件的加工和制造有一定的指导意义。

Sexuality, Gender &Policy, Volume 7, Issue 4, Page 348-365, November 2024.Abstract In the armed conflict between Kashmiri militancy and the Indian state forces, Kashmiri women have been relentless victims of abduction, rape, molestation, and cruel objectification by the militaristic patriarchs of both sides. In the context of the state's unaccountability, the rebuttal of justice is horrific in Kashmir.

Dianci bileiqi, 2022 圆柱头和圆锥头盘形悬式瓷绝缘子的内、外绝缘性能在理论上无本质差别。相比圆锥头瓷绝缘子，圆柱头瓷绝缘子重量明显减轻，可有效降低杆塔导线的机械载荷；并且对于材料性能经时变化有较好的分散和调整能力，使得产品不受过大应力及不均匀应力的长时作用，具有较高的可靠性。为进一步提升圆柱头绝缘子产品的机械性能，笔者在不改变绝缘子铁帽及瓷件结构的前提下，建立了钢脚参数化的精细仿真模型，通过有限元法计算分析钢脚几何参数对圆柱头瓷绝缘子机械性能的影响，为产品优化提供设计参考。

Study on Flame Retardant Resin Matrix Composites [PDF]
, 2015 苯并噁嗪（BOZ）树脂是一种新型热固性树脂基体，其固化过程体积接近零收缩，耐热性优良，还拥有与传统酚醛树脂类似的优异阻燃性能。为了将BOZ树脂基复合材料应用在更高阻燃要求的场合，还需对其进行阻燃改性。黄麻纤维具有资源可再生、综合性能良好、价格低廉等优点，其复合材料在汽车内饰、轨道交通、建筑家装等领域有巨大的应用前景，但黄麻纤维易燃，必须对其进行阻燃改性。本文利用聚磷酸铵（APP）和碳纳米管（CNT）对BOZ树脂及其玻璃纤维（GF）复合材料进行了阻燃改性，以及利用水性 ...
