The quantization condition is that the average lyapunov exponents show local minima as a function of the classical energy . this emphasizes that the quantized levels request the least global chaoticity 这一观点强调了体系的量子能级具有整体的最小混沌程度,是从混沌的角度来研究量子化问题的。
This is better psychovisually because it means that the perceptually least valuable component of vision is quantized first . simulations were carried out w ith the shepp - logan brain phantom 在分解抽样中,使用梅花五点式的抽样方法,这种对角线方式的取浙江大学博士学位论文样方法更符合人类视觉。
