Phase regulated suppression and enhancement switches of four-wave mixing and fluorescence

引用

Frontiers of physics 2014年第2期9卷 153-156页

作者： Zhi-Guo Wang Peng Ying pei-Ying li hua-Yan Lan He-Qing huang Hao Tian Jian-Ping Song Yan-Peng Zhang Key Laboratory for Physical Electronics and Devices of the Ministry of Education Shaanxi Key Lab of Information Photonic Technique Xi'an Jiaotong University Xi'an 710049 China

We experimentally study the phase regulated switch between elcctromagnctically induced trans- parency and electromagmetically induced absorption in probe transmission signal and the conver- sion between enhancement and suppression in four-wave mixing and fluorescence signals for the first time. By changing the relative phase, electromagnetically induced transparency can be eonverted into electromagnetically induced absorption. In this process, the conversion from suppression to enhancement is also obtained in four-wave mixing and fluorescence signals. This research can be applied in non-linear optical device like optical switch and optical wavelength convertor.

目的:考察团体心理辅导应用于心理健康教育课程的可行性与有效性。方法:选取一年级的两个班,一个为团体心理辅导班46人,进行为期30课时,共15次的团体辅导,另一个班为对照班(50人),不进行团体辅导。团体辅导前后采用SCL-90分别对两个班的学生施测,团体辅导班学生另自评课程内容和教学效果。结果:团体辅导班与对照班相比,团体辅导后学生的SCL-90总分及除恐怖、躯体化因子外的各因子分均低于对照班,有统计学显著意义(t=2.14-4.38,P<0.01),其SCL-90总分降低值(24.47±7.23)大于对照班的总分降低值(13.35±2.49,t=6.24,P<0.01)。除学习辅导、生涯规划外,团体辅导班有93.4%(43/46)的人认为专题辅导对自己有不同程度的帮助,学生满意的专题与活动排在前三位的是小组成立、人际交往、情绪管理。结论:团体辅导应用于心理健康教育课程,并创造性地展开师生、生生之间的多向对话,对提高学生心理健康水平和促进心理健康教育课程教学改革是有效的。

在三维非恒定渗流有限元计算中,不可避免地需计算自由面上的边界积分项。建议一种高精度数值积分的方法求取自由面边界积分项。其基本思路是,基于8节点空间等参单元,根据压力为零的边界条件确定自由面满足的曲面方程,将自由面边界积分转化为ξη平面上的二重积分;然后再计算自由面与三维等参单元的交点,将交点投影到局部坐标平面ξη上,并根据点与线的相对关系,确定投影点所围成的局部坐标积分区域;再将总积分区域划分成若干个三角形子区域,并利用变步长Simpson方法计算各三角形子区域上的二重积分,从而实现了高精度的自由面边界积分。该方法避免了单元中自由面为平面的假设,可提高计算精度,特别对于单元内自由面变化剧烈情况,更为显著。将该方法应用于砂槽模型和土坝的渗流分析中,计算结果与实际情况较为接近。
