查询词典 deviation factor

In this thesis, several problems of time-dependent systems in various branches of physics are investigated by making use of the generalized invariant theory and the invariant-related unitary transformation formulation. The problems are given as follows:(1) Spin model and geometric phase factor in the fiber We investigate the fiber experiment performed by Chiao-Tomita and the Chiao-Wu theory concerning the geometric phase factor in the optical fiber, and then show that the investigation of the propagation of photons inside the noncoplanar optical fiber can be regarded as that of a second-quantization spin model.

本论文用推广的不变量理论和与不变量有关的幺正变换方法研究了一些物理分支中的几个含时系统问题：(1)自旋模型与光纤中光子几何相因子问题重新考察了Chiao-Tomita光纤实验和Chiao-Wu关于光纤中光子几何相因子的理论，证明了在非共面弯曲光纤中传播的光子运动问题实际上可以化为二次量子化含时自旋模型研究。

The third chapter talked about two different treatments of quantum decoherence in V〓 system. For one the decoherence factor is been expressed in the form of a random external field. And the mean density matrix is calculated to signal the decoherence by showing its nondiagonal elements to approach to zero. In another numerical work done by us, random interaction between system and environment is imposed to mimic the decoherence factor.

第三章讨论了V〓体系中量子相干性研究的两个工作，一个用随机外场来代表消相干因素，采用对系统的密度矩阵进行随机平均的解析方法得到一些结果，一个是我们用数值计算方法的处理，其中消相干因素考虑成系统和环境的相互作用。

结果显示：(1)优生、差生的非智力因素发展水平不同，但发展顺序一致，初二是非智力因素发展的转折期；(2)非智力因素在优生中普遍高于同年级差生；并对优生、差生学习成绩影响差异显著；(3)智力因素与非智力因素呈显著正相关，它们共同影响学习成绩。

0引言 在试验设计时设置重复试验，能够估计试验误差；重复试验次数越多试验误差越低，试验精确度越高。一般认为，适宜重复次数应保证使误差项自由度至少为12，否则F检验或t检验的临界值上升很快，难以呈现显著性川。
