| 7 | FINITE ELEMENT METHOD ON NUMERICAL SIMULATION OF STRATUM CORNEUM'S PENETRATION PROPERTY显示文摘How the outer substance could penetrate through the skin lies in the stratum corneum, because it is the main barrier in the multi-layers of the skin. Supposing the keratin cell with a special geometry as tetrakaidecahedron, the penetration property of stratum corneum was the key problem which was numerically simulated with finite element method. At first the discretization of the stratum corneum region was given in two steps: first, the discretization of the keratin cell; second, the discretization of fattiness that surrounds the keratin. Then there was the work of numerical simulation. In this procedure, the finite element method and the multi-grid method were used. The former was to obtain the discretization of basic elements; the latter was to decrease the high frequency error. At last the visualization of the numerical simulation was shown. | 刘宇红 乔爱科 Dirk Feuchter Gabriel Wittum 曾衍钧 | 2006 | Applied Mathematics and Mechanics(English Edition)2006，27，4： | 1 |

| 18 | 角质层渗透性质的三维数值模拟显示文摘目的从数值模拟的角度研究药物渗透皮肤角质层的过程,为实际的药物工作者提供理论上的指导和帮助。方法用有限元方法离散偏微分方程的差分格式,将角质层的角蛋白细胞近似为物理学上经典的由6个四边形和8个六边形围成的三维十四面体结构,同时将角蛋白细胞间的脂质体视为十四面体结构的一部分,离散其相应的单元网格。结果得到了药物渗透皮肤角质层的三维数值模拟,并给出了模拟过程中浓度和速度变化的可视化效果示意图。结论本文所采用的几何模型与实际的生理结构模型非常接近,数值模拟结果证明这一方法对实际工作有参考意义。 | 刘宇红 Dirk Feuchter Gabriel Wittum 张恩平 曾衍钧 | 2004 | 航天医学与医学工程2004，17，4： | 0 |
| 19 | 一种多层三维几何结构的网格拆分方法显示文摘为了采用偏微分方程求解流体的多层复杂几何结构的渗透性质,本文提出了一种多层三维复杂几何结构的网格拆分方法,尤其对多层结构中的核心——1个由6个四边形和8个六边形围成的十四面体(即物理学上经典的Tetrakaidecahedron体)的空间拓扑几何结构进行了详细的分析.在完成单元体向整体结构拼接的过程中,采用一种将单元体视为内外两层的思路,既有效地存贮了网格点的信息,又大大减少计算量.并讨论了影响十四面体几何性质的参数对所生成的网格性质的影响. | 刘宇红 Dirk Feuchter Gabriel Wittum 曾衍钧 | 2006 | 北京工业大学学报2006，32，4： | 0 |
| 20 | 角质层渗透性质的有限元数值模拟计算显示文摘角质层是皮肤屏障作用的最主要部分,它决定可外界物质对皮肤的渗透情况。本研究在假设角质层细胞为一种三维的十四面体(物理学经典的Tetrakaidecahedron体)下,进行对角质层渗透性质的数值模拟工作。为此,首先完成了对角质层空间结构的网格拆分,拆分过程分两步进行:首先对角蛋白细胞的网格拆分;然后对角蛋白细胞周围的网状脂质体的网格拆分。在数值模拟过程中,则用有限元法得到方程的离散格式,用多重网格算法降低高频误差,提高计算精度。最后,给出了数值模拟结果的可视化效果图。 | 刘宇红 Dirk Feuchter Gabriel Wittum 张恩平 曾衍钧 | 2006 | 中国生物医学工程学报2006，25，2： | 0 |
