| 1 | 日本软岩边坡工程的新发展显示文摘日本是一个多滑坡灾难的国家,也是一个有着丰富研究滑坡经验的国家,多年来对各种起因的滑坡破坏现象进行了大量的调查,在研究技术上也取得了很大进展,并能在设计领域里科学地加以控制。 | K.Kikuchi Y.Kitahara H.Nakamura S.Tanaka O.Tsuruta R.Yoshinaka 魏嘉昆 | 1989 | 露天采矿技术1989，，2： | 0 |
| 2 | 日本软岩边坡工程的新发展(续)显示文摘2.力学性质图4表明设计方法的应用与力学性质密切结合,特别是:滑弧和复杂滑动面方法,剪切强度;有限元的静态分析,强度和形变特征,包括应力、应变间的关系。有限元法的动态分析,动态剪切强度,动态形变率和衰减系数,必要时,对动态应变强度提出再定量。这些力学性质能够由现场试验获得的结果来较好地确定。(1)关于强度或变形特性,许多作者已经提出过理论的或实际的经验公式。 | K.Kikuchi Y.Kitahara H.Nakamura S.Tanaka O.Tsuruta R.Yoshinaka 魏嘉昆 | 1989 | 露天采矿技术1989，，3： | 0 |
| 3 | Refueling for Steady-State Plasma by Repetitive Pellet Injection in Large Helical Device显示文摘A repetitive pellet injector has been developed for investigation of refueling issues towards the steady-state operation in Large Helical Device (LHD). Continuous operation of more than 10000 pellet launching at 10 Hz has been demonstrated. The maximum repeating rate is 11 Hz. No technical constraint for longer operation has been found. The reliability of pellet launch has exceeded 99.9%. The initial application to the NBI-heated plasmas has been successful in the last experimental campaign of LHD. Although the pulse length is limited by the operational constraint of NBI, the plasma with a density of 8×10^19 m^-3 has been sustained for 2 s by the pellet injection at 10 Hz. A prospect for the future experiment is discussed on the basis of the initial result. | H.Yamada R.Sakamoto I.Viniar M.Goto K.Kikuchi A.Lukin S.Masuzaki J.Miyazawa S.Morita Y.Oda S.Sudo K.Tanaka | 2004 | Plasma Science and Technology2004，6，3： | 0 |
| 4 | Arc Power Limit and Distribution on the Large Negative Ion Source Based on JT-60 NNBI显示文摘The target of the large negative ion source based on neutral beam injection (N-NBI) is to produce neutral beam current of 22 A and beam power of 10 MW at 500 keV with duration time of 10 s. Since it was successfully operated in 1996, the 5.3 MW neutral beam power at 380 keV with duration time of 3 s has been achieved. In recent years improving and enhancing the beam power are going on. Several reasons such as plasma non-uniformity, higher beam density at the upper region in the beam profile, | LEIGuangjiu N.Umeda M.Kawai T.Yamamoto M.Kuriyama T.Ohga N.Ebisawa T.Yamazaki M.Kusaka K.Kikuchi S.Hikida K.Usui M.Kazawa S.Numazawa K.Mogaki A.Honda F.Satoh S.Norio K.Ooshima | 2001 | Southwestern Institute of Physics Annual Report2001，，1： | 0 |
