3) The heavy-ion micro beam radiation facility
重离子微束辐照装置
1.
The heavy-ion micro beam radiation facility can limit the heavy-ion accelerator beam, which size is about few mm of diameter, to few μm, using aperture or focused technique.
重离子微束辐照装置是一种将常规加速器产生的重离子束斑(直径为毫米量级)通过准直或聚焦的方法限制到微米水平的辐照装置。
4) Heavy ion irradiation
重离子辐照
1.
In order to study biological effects of heavy ion irradiation on maize inbred lines, the agronomic traits and photosynthetic rates were investigated from M1 to M3 of maize seeds irradiated with 12C6+ and 36Ar18+ ions.
结果表明:种子发芽势和发芽率随辐照剂量的增加而下降,不同生理状态的种子对重离子辐照的敏感性也不同。
5) low-energy N~+ beam implantation
低能离子束辐照
1.
The results showed that the low-energy N~+ beam implantation could promote the transcription of the Wis2-1A and restrain the expression of the retrotransposon s flanking gen.
为研究小麦反转录转座子Wis2-1A在低能离子束辐照小麦生物效应中的作用,用实时定量PCR的方法测定不同注量下Wis2-1A的转录水平及在基因组中的拷贝,并用转座子显示技术研究了Wis2-1A在注量为5×1017N+/cm2的低能离子束处理后的转录对其邻近基因表达的影响,结果显示:不同注量的N+辐照都能提高Wis2-1A的转录水平,但在基因组水平上的拷贝没有大的提高,且在较高注量下,由于Wis2-1A的高水平转录导致其邻近的某些基因沉默,这说明Wis2-1A在低能离子注入生物效应中起主要作用。
6) heavy ion irradiation simulation
重离子辐照模拟
1.
Dependence of radiation damage in the modified 316L stainless steel has been investigated on irradiation temperature from room temperature to 802 ℃ at 21 and 33 dpa and on irradiation dose up to 100 displacemets/atom(dpa) at room temperature by the heavy ion irradiation simulation and positron annihilation lifetime techniques.
用重离子辐照模拟和正电子湮没寿命技术研究了改进型 316L不锈钢在 21和 33dpa辐照剂量下的辐照损伤在室温到 802°C温度范围随辐照温度变化和室温下 0—100dpa剂量范围随辐照剂量变化。
补充资料：重离
1.《易．离》:"明两作离，大人以继明照于四方。"孔颖达疏:"明两作离者，离为日，日为明。"《离》卦为离上离下相重，故以"重离"指太阳。 2.古以帝王喻日，因本《易．离》之义，以"重离"指帝王或太子。
