The continued existence of high-energy radiation in nuclear reactors at high temperatures results in the formation of radiation-induced voids,which will further lead to inevitable swellings of polycrystalline structural components and thus premature failures.A deep understanding of the effect of temperature and grain boundary on void evolution in irradiated copper is significant for preventing this kind of ***,the phase-field method was employed to study void evolution in irradiated copper under different temperatures and grain *** results show that,due to the different sensitivities of point defect production rate and vacancy diffusion rate to temperature changes,both the nucleation-growth rate and the coarsening rate during void evolution increase first and then decrease with increasing temperature;moreover,the nucleation mechanism exhibits site-saturated nucleation at low temperatures while continuous nucleation at high *** presence of grain boundary can accelerate the emergence of void because grain boundaries can absorb more interstitials than *** finer the grain size,the stronger inhibitory effect of grain boundaries on the growth rate of void,due to the formation of void denuded zone near grain *** high temperatures,the growth rate of void in fine grains is significantly reduced due to the increase of vacancy diffusion rate and the enhancement of sink effect of grain boundary on vacancy.

【目的】检验鼠李个体大小对其生殖分配的影响,比较相同径级雌雄鼠李生殖分配的差异,探讨鼠李可能存在的生殖耗费补偿机制,对今后雌雄异株植物生理生态学方面的研究提供论据支撑。【方法】在鼠李的花期和果期选择当年进行繁殖活动且生长状况与立地条件类似的植株作为调查样本,对每株鼠李的性别、叶生物量、花生物量(花期)、果生物量(果期雌株)进行了调查,通过Li-6400便携式光合作用测定仪比较不同性别鼠李叶片的光合能力。【结果】(1)大径级鼠李的生殖生物量与营养生物量均显著大于小径级鼠李(P 0.05)。(3)当光强处于500~2 000μmol/(m2?s)时,鼠李雌株单位叶面积的光合速率大于雄株。【结论】研究区域内鼠李的个体大小对其生殖分配有显著影响,这是不同个体可利用资源总量不同造成的。鼠李雌株相较于雄株,并没有因较高的生殖耗费而缩减对营养生长的投入。鼠李雌株通过光合作用获得了更多的可利用资源来满足其生殖和营养生长过程需要,这种较强的光合能力是雌株在较高繁殖压力下进化出的一种生殖耗费补偿机制。

传统结构材料限制了铅铋核能系统性能的进一步提高,为给铅铋反应堆提供高性能结构材料,针对高强Al_(17)Cr_(10)Fe_(37)Ni_(36)多主元合金开展了高温静态铅铋合金环境相容性研究。研究表明,在500~600℃的铅铋饱和氧环境下,合金形成致密的Fe-Cr-Al-O氧化膜与疏松的氧化铁双层氧化膜结构,双层氧化膜厚度仅有1.5μm,氧化膜生长速率极低;Fe-Cr-Al-O氧化膜在高温铅铋环境具有极佳的致密性、结构与组织稳定性,显著保护了液态铅铋向基体溶解。相比于传统的铁素体/马氏体钢(F/M钢)、奥氏体不锈钢,Al_(17)Cr_(10)Fe_(37)Ni_(36)多主元合金在高温铅铋环境中应用具有明显的优势。
