He
1.
In order to investigate the effects of helium on the excess point defects and secondary defects processes in low activation Fe-Cr-Mn(W, V) alloys during electron beam and electron-He+ ion dual beam irradiation, the in situ observation was carried out using a high voltage electron microscope connected with an ion accelerator.
采用超高压电镜与离子加速器相连结的复合辐照装置,研究了注He对低活性Fe-Cr-Mn(W,V)合金辐照产生的点缺陷及二次缺陷行为的影响。

1.
Nucleation and growth of He bubbles at different annealing temperatures T≤1023 K in stainless steels HR-2 and SS321, implanted with He~+ (40—70 keV, 1×10~(16)-6×10~(17) He~+ /cm~2), were observed under TEM.
本文利用透射电镜观察了HR-2及SS321不锈钢注入He~+并在T<1023K不同温度退火后的He泡结构,发现T=0。
2.
TEM observations show that about 1 nm sized He bubbles appear in Pd_(91.
19)合金膜中,观察到分布均匀、直径约为1 nm的He泡,同时存在高密度的位错及位错环,在老化295 d的样品中,He泡直径略微增加,达1。
补充资料:人类环境
人类环境
human environment
人类赖以生存、从事生产和生活的外界条件。人类作为有理性的动物,不仅生活在自然界具有生物属性,而且生活在人与人之间关系总和的复杂社会中,又具有社会属性,所以人类环境包括人类生命维持系统中的外界环境的全部因素,即包括自然环境和社会环境两部分。
