And there are no significant differences between the two sites. The human preadipocye is composited with scaffold material, and then it implants in nude mice subcutaneously. The new fat tissue also can be observed, but it is sheet, not lumpish or hemispheroidal. We still do more research in the field of growth and control of cell, screening better scaffole material in future study.

两个部位无显著性差异，将人的前体脂肪细胞与支架材料复合后接种裸鼠皮下，也能形成新脂肪组织，但为片状，不能形成团块状或半球状，今后还将对细胞的生长调控、更好的筛选成形支架材料等进行深入研究。

Then, the dynamic behaviors of Lur'e system have been analyzed through the simulation method, and the paper presents that the final dynamic behaviors of the system are sequentially changed according to the following states: the unstable dispersing state, chaotic state, steady cycle state and balanced state respectively with the filtering wave function from weak to strong and under the condition of meeting parameters.

以一维逻辑斯蒂方程为工具，论证了一类非线性Lur'e系统通过周期倍化达到混沌的机制，深入研究了该系统由混沌转化为有规律的周期性问题，并通过仿真分析了Lur'e系统的动力学行为，得出了这类系统在满足参数条件下，随着滤波作用的由弱到强，系统的最终动力学行为依次按着不稳定的发散状态、混沌状态、稳定的周期态、平衡态的顺序变化。
