摘　　要：由一维线性谐振子引入q-形变谐振子,构成q-形变谐振子的量子Heisenberg-Weyl代数,构造了SU(2)q-奇偶相干叠加态,计算了在此态下的期望值,通过理论计算作图研究了其非经典效应.发现由于形变参数的影响,其压缩效应和反聚束效应具有丰富的结构.The qdeformed harmonic oscillator is introduced from one dimension harmonic oscillator,to constitute the quantum HeisenbergWel algebra.The superposed states of SU(2)′s odd and even qcoherent states are constructed and the expectation values for these states are calculated.The noncl assical properties are studied by calculating and ploting.It is found that their squeezing and anti bunching effects have plentiful structures due to the influence of the deformation parameters.
