In tills paper, the orthogonal q coherent state is constructed, its quantum statistic properties such as squeezing property, antibunching effect are studied, the effects of variable q on quantum statistic properties are studied by making use of numerical calculation. 要本文构造了正交q一相干态,研究了它的压缩性质、反聚束效应等量子统计性质,并数值计算了变形参数q的影响。
Compared with the results simulated separately by the neural network method and river dynamics method based on the variable of Q and Z. the calculation results of new model are found agreeable. 将其应用于长江宜昌-螺山段实际洪水演进计算,并且其计算结果与用神经网络模型和基于Q、Z为因变量的水动力学方法计算的结果进行了比较,取得了满意的结果。
The thesis mainly studies the properties of quasi-maximum likelihood estima-tor ( QMLE ) in nonlinear models when response variable is q dimension, many results in literatures are extended. 本文主要研究了响应变量是多维时非线性模型中极大拟似然估计的性质,推广和发展了非线性模型中关于极大拟似然估计的相关结论。
And both the wh-phrase and the trace in proper theta position are connected to a variable bound by a Q operator in semantics. 在语义中,wh-短语和处于题元位置的语迹都与Q算子约束的一个变量连接。
A concave shape micromachined variable capacitor was presented which has high Q and wide tuning ranges. 提出了一种高Q值、宽调节范围的凹型结构微机械可变电容。
