第三个吻痕 - 何水水

论文介绍了三向测缝计的工作原理，并结合工程实例，分析三向测缝计在煤窑沟水库整体式面板周边缝监测中的点位布设、采集监测数据，深入分析三向测缝计在混凝土砂砾石面板坝中的应用，从分析结果判断坝体面板结构结构是否运行安全，为混凝土砂砾石面板坝工程建设安全监测提供了有利的参考依据。

We present a comment on a recent letter by B. Edwards, N.W. Ashcroft, Nature 388 (1997) 652, in which the dielectric instabilty of the phase III of the solid molecular hydrogen system is suggested on the basis of electrostatics.

We present theoretically calculated optical functions for Cu$_2$O quantum well (QW) with Rydberg excitons in an external, homogeneous electric field parallel to the QW planes for the energy region above the gap, suitable to observe the Franz-Keldysh (FK) oscillations. We quantitatively describe the amplitudes and periodicity of FK modulations and the influence of both Rydberg excitons and confinement effect on this phenomenon.
