1.The neutron exposure per pulse deduced for the s+r stars lies between 0.45 and 0.88 mb-1. The formation of a Pb star ([Pb/Ba]>1.0) could be explained by a transfer of matter from the low-mass AGB star(M<3.0M(?)
本文计算得到,12颗s+r星对应的中子辐照量取值范围是0.45—0.88mb~(-1)。 铅星([Pb/Ba]≥1.0)可能来自低质量(M<3.0M_?)AGB星的污染。收藏指正
2.The distribution of X,γ dose rate was mea-sured with TLD dosimeter during the operation of neutron generator,the exposure rate and γ spectrawere measured nearby target holder with FJ-311G dose meter and a 3″×3″Nal(Tl)detector respec-tively after the generator having been operated for one hour and under the condition of neutron yeild of3×10~9 s~(-1).
用 FJ-377型热释光剂量仪测量了中子发生器运行过程中 X、γ射线照射量率分布; 用 FJ-311G γ微伦仪和 NaI(Tl)γ能谱仪测量了中子发生器在产额为3×10~9n/s条件下,运行1小时后,靶头附近的照射量率及γ谱。收藏指正
