| 1 | Plasma Confinement Characteristics in Heliotron J——Spontaneous Change of Plasma Confinement State显示文摘Spontaneous transition of the plasma confinement mode was observed in the helicalaxis heliotron device 'Heliotron J' for three different plasma heating schemes, i.e. ECHonly, NBI-only and the combination of ECH and NBI. The transition seems to occur above a certain critical density. In addition to the confinement transition, a spontaneous shift of the hitting position of the divertor plasma flux on the wall was observed. This shift could be related with the change of the edge field topology caused by non-inductive toroidal currents. | T.Mizuuchi H.Okada K.Nagasaki S.Kobayashi S.Yamamoto F.Sano K.Kondo K.Hanatani M.Nakasuga Y.Nakamura Y.Suzuki Y.Manabe H.Shidara H.Kawazome M.Kaneko Y.Nishioka Y.Ohno T.Takamiya H.Yukimoto Y.Fukagawa Y.Morita S.Nakazawa S.Nishio K.Takahashi S.Tuboi M.Yamada K.Ohashi Y.Ijiri T.Senju K.Yaguchi K.Sakamoto K.Tohshi M.Shibano T.Obiki | 2004 | Plasma Science and Technology2004，6，4： | 1 |
| 2 | 托卡马克偏滤器中脱体等离子体的稳定性的一维模拟显示文摘用一维流体程序研究了托卡马克刮削层(SOL)中辐射阵面的稳定性;在平行于磁力线的方向上求解与时间相关的输运方程。当从芯部进入SOL等离子体的能量减少时,稳态的附着解转变成稳定的脱体解。一达到这样的稳定脱体态,强辐射阵面就与偏滤器钯相接触或与之有一小段距离。当输入的能量进一步减少,且总的损失大于输入功率时,辐射阵面开始向X点移动,使SOL等离子体冷却。在这种情况下,在我们的参数空间内得不到辐射阵面停留在偏滤器通道内的解。这与托卡马克偏滤器实验的结果定性一致,该实验表明了辐射阵面的移动。 | S.Nakazawa 雨扬 | 2002 | 国外核聚变2002，，3： | 0 |
| 3 | High-temperature deformation of L1_2-FCC two-phase Ir-15Nb-Ni refractory superalloys显示文摘The creep behaviors of the Ni added Ir 85 Nb 15 alloys were investigated at 1?650~1?800?℃ by compression tests in vacuum. X ray diffractometry, transmission electron microscopy and scanning electron microscopy were conducted to characterize the microstructure and lattice misfit change by the addition of Ni in the Ir 85 Nb 15 alloy. The results reveal that the Ni addition has a significant effect on the creep resistance of the Ir 85 Nb 15 two phase refractory superalloys. Basing on the results, the relationship among the Ni addition, lattice misfit, microstructure development, and the creep behavior in the Ni added Ir 85 Nb 15 alloys is discussed. | Y.F.Gu, Y.Yamabee Mitarai, S.Nakazawa, H.Harada (National Institute for Materials Science, 1 2 1 Sengen, Tsukuba, Ibaraki 305 0041, Japan) | 2002 | 中国有色金属学会会刊:英文版2002，12，4： | 0 |
