centroid effect

Effects of the quantization of atomic center of mass motion on the quadrature squeezing of the quantum light field are discussed, by considering that the atom in the Jaynes Cummings model is ultracold.

考虑Jaynes Cummings模型中与光场相互作用的原子为超冷原子 ,讨论了原子质心运动的量子效应对光场两正交分量量子噪声压缩的影响 ,结果表明 ,在Jaynes Cummings模型中 ,原子质心运动的量子效应增加光场两正交分量的量子噪声 ,使其压缩效应消

Pressure decouple effect of eccentric decouple charge blasting is researched according to cement mortar model testing,meanwhile comparable testing of smooth blasting of eccentric and centric charge is researched on rock with sonic velocity evaluation in this paper.

通过水泥沙浆模型试验研究了偏心不耦合装药爆破的偏心效应,同时在石灰石块体上通过岩石声速评价对比试验,研究了药柱偏心和同心的光面爆破。
