| 摘 要： | 构造了一个具有分形边界的无限深势阱，得到各阶势阱的波函数和相应的能级规律．结果发现，能级在空间尺度变换下具有标度不变性．各阶能级间具有相互嵌套的性质，即自相似性．随边界阶数的增加，粒子几率密度可出现局域化现象．

| Abstract: | The mean scatterer spacing of spleen is estimated by cepstral and wavelet transform technique, the results obtained in vitro are different from that in vivo. The connection between cepstrum and wavelet transform is shown to be a feasible method in mean scatterer spacing estimates. |
