水凝胶具有类似于细胞外基质的理化性质，具备良好力学性能、自愈合能力和响应性，可用于构建组织再生的微纳米仿生结构，并提供微米尺度的表面形态来调节细胞行为，如细胞粘附、迁移或生存增殖分化因子的释放。因此，水凝胶被广泛应用于组织工程和药物递送等领域。然而，制备高精度的三维（3D）任意生物相容性水凝胶支架颇具挑战性。为了适应未来生物医学领域的发展，亟需开发具有精细3D几何结构的新型水凝胶材料。

单模激光Lorenz系统与3D混沌系统之间的混沌同步
非线性反馈 3D混沌系统 Lorenz混沌系统 混沌同步
2007/12/8
研究了异结构混沌系统之间的同步控制问题.采用非线性反馈控制方法实现了3D混沌系统和单模激光Lorenz混沌系统之间的混沌同步.根据系统的稳定性理论,得到了非线性反馈控制器的结构和反馈控制增益的取值范围.仿真模拟的结果表明:目标系统和响应系统达到完全同步,两系统状态变量随时间的演化轨迹完全一致,并且误差变量经过短暂的时间序列以后始终平稳地趋于零.仿真模拟的结果证明了这种方法的有效性.
