Investigate the Effect of Resveratrol on Postovulatory Aging of Mouse Oocytes [PDF]
, 2016 大多数辅助生殖技术在体外操作，随着操作时间的延长，未受精的第二次减数分裂中期的卵母细胞会经历老化的过程，此过程限制了卵母细胞发展的潜力和受精的能力，因此如何延缓卵母细胞的老化为操作争取更多的时间是提高辅助生殖技术成功率的关键。然而，至今仍没有合适的方法能克服卵母细胞在体外发生的老化。本文的研究目的是探讨白藜芦醇是否可以改善排卵后老化的卵母细胞在体外发生的不良结局，之前有研究表明白藜芦醇可以提高不同物种在体外受精的概率。我们用小鼠第二次减数分裂中期的卵母细胞作为对照组 ...

Strangers on the ladder of the party‐state: Women in teaching in Nationalist Taiwan, 1940s–1980s
Gender &History, EarlyView.Abstract As the ruling party of a party‐state in China and Taiwan, the Nationalist Party (Kuomintang/Guomindang) built a close relationship with the teaching profession. Many teachers joined the party and there was a well‐trodden pathway from teaching into local representative politics and civil service.

Gentrification Everywhere? Delinking Culture‐Led Regeneration From Gentrification
The Developing Economies, EarlyView.ABSTRACT This paper challenges the prevalent use of “gentrification” (shishen hua [士紳化/仕紳化] or jinshen hua [縉紳化]) as a catch‐all critique of culture‐led regeneration and neighborhood transformations, including rent increases and shifts in aesthetic and tastes, in Sinophone Asia and beyond.

Gaoya dianqi, 2013 针对在役复合绝缘子的老化问题,笔者分别对实验室电晕老化和现场自然老化的HTV硅橡胶材料的憎水性、泄漏电流、表面微观形貌以及化学成分等特性进行了对比研究。结果表明,电晕老化与现场老化造成材料特性变化的规律呈现一致性:电晕老化造成材料憎水性下降,且提高电晕老化强度（电压和时间）则导致憎水性恢复变慢,甚至不能完全恢复;现场老化材料的憎水性随年限不断下降,由HC1级（2年）降至HC5级（15年）。老化还造成样品的表面电阻率下降,引起表面泄漏电流增加;老化造成硅橡胶材料降解,表面缺陷增加,孔洞增加并加深 ...

Dianci bileiqi, 2019 复合绝缘子广泛应用于输电线路中,运行年限也越来越久,长期挂网运行的复合绝缘子同时受到运行环境和自然条件的影响,致使复合绝缘子老化问题越来越受到人们的关注。选取不同运行年限的110kV复合绝缘子作为研究对象,通过对伞裙材料进行憎水性测试和红光光谱分析,研究复合绝缘子老化特性及老化机理。结果表明:复合绝缘子沿串伞裙老化呈非均匀性分布,两端伞裙表面老化严重,中间位置伞裙老化程度较轻。上伞面老化严重,下伞面老化较轻;伞裙内侧较外侧老化严重。
