J*******3 发帖数: 1651 | 1 我国半导体物理研究进展
夏建白 黄 昆
半个世纪以来,半导体的研究在当代物理学和高技术的发展中都占有突出的地
位.这是因为半导体不仅具有极其丰富的物理内涵,而且其性能可以置于不断发展的精
密工艺控制之下.传统的晶体管、集成电路以及很多其他半导体电子元件都是明显的例
证.半导体超晶格和微结构则是近年来开拓的新领域,它在一个新的水平上体现了以上
半导体的特点,这个领域的开拓正有力地推进半导体研究和新一代高技术的发展.
除了半导体超晶格和微结构以外,表面、界面和杂质、缺陷是半导体物理的两个传
统研究领域,研究历史较长.这两个领域都是和半导体材料、器件性能的改善有密切的
联系,因此预期今后将继续发展下去.表面、界面方面最突出的进展是扫描隧道缇档姆

半导体材料是半导体物理研究的基础,半导体新材料、新结构的研制成功大大促进
了半导体物理研究.生长半导体超晶格材料的分子束外延等技术是超晶格领域能够形成
并不断发展的基础.最近,多孔硅、C60、GaN等每一种材料的... 阅读全帖 |

g*x 发帖数: 141 | 10 Syracuse一共1245人完赛,从1246名开始,成绩都是组委会硬塞的,8小时20多分钟,
一名一秒,一直到8小时30分为止,一直到1599名。当然,最后一名2小时20分能不能跑
完是个问题。
未完赛的第一名是1246名,我是1265名,很靠前嘛!
我的年龄组,完赛一共38人,我第39,牛不牛!最后一直给到第58名呢!
跑步,如果不下雨,我是能跑进两小时的。M18-24实际完赛的人,只有前16名跑步进了
两小时。哈哈!看来我跑步不错嘛!我之后的几个人,跑步一上来都是11、12分的pace
。我虽然不快吧,但下雨之前一直是9分多的pace。
本来伤心了好久,现在还挺开心的!
另外给我们年龄组第38名跪了,下雨之前三个计时点都是10+甚至12+的pace,终点前最
后一个计时点只比我快3分钟。然后我停了,那么大的雨,他居然冲到9+的pace完赛了
!服! |

Market Quiet, Stocks Moving; Look for Relative Strength

Indices are basically flat but there has been some stock specific action.
The S&P is still holding above recent floor of 1265, but still can’t break
above 1280-1284. Make sure to be looking for relative strength--and weakness

l****u 发帖数: 2778 | 25 1254附近压力无限大,正在等突破。。。如果突破1255上面可到1265-1267,别忘记大减仓 |

l****u 发帖数: 2778 | 26 喊早了一天,郁闷呢,昨天该去这个点的。。。。
明天在1254以上运行的话,可能会去1265-1267,1267比最低点667多了600点整,建议减仓为宜。。。
特殊位置不能不回避! |
