| 1 | MINERALOGICAL FEATURES OF ULTRAMAFIC HYPOXENOLITHS IN ALKALI-RICH PORPHYRY显示文摘Ultramafic hypoxenoliths found in the alkali-rich porphyry in the Liuhe Village, Heqing, Yunnan,China, are of great significance in understanding the origin and evolution of the porphyry. This paper discusses the mineralogical features of the hypoxenoliths. It shows that the xenoliths are characterized by the upper mantle rocks modified to certain extent by the enriched mantle fluid metasomatism in the mantle environment, with the enriched mantle property of Iow-degree partial melting. This constitutes the important mineralogical evidence for the petrogenesis and mineralization of alkali-rich porphyry. | LIU Xianfan , YANG Zhengxi, LIU Jiaduo, ZHANG Chengjiang, WU Dechao and LI Youguo(Institute of Earth Science, Chengdu University of Technology, Erxianqiao Dongsan Road 1#,Chengdu, SC610059, China) | 2003 | Geotectonica et Metallogenia2003，27，1： | 2 |
| 2 | Three-dimensional discharge simulation of inductively coupled plasma (ICP) etching reactor显示文摘More and more importance has been attached to inductively coupled plasma (ICP) in semiconductor manufacture. For a deep understanding of the plasma discharge process in the etching reactor, this study made a three-dimensional simulation on the Ar plasma discharge process with the commercial software CFD-ACE, which is according to the real experiment conditions and data supplied by North Microelec-tronic Corporation. The error of the simulation results is in the range of ±20% with credibility. The numerical results show that the three-dimentional spatial distribu-tion of electron density is reduced from the chamber center to the wall. The distri-bution of electron density, electron temperature and power deposition is related to the shape and placement of the coil. | AN YiRan LU YiJia LI DongSan CHEN YaoSong | 2008 | Science China(Technological Sciences)2008，51，6： | 2 |
