PLIC3D algorithm, a 3-dimensional VOF method with piecewise linear interface construction and split and unsplit propagation, is specially devised for better solution to free surfaces. Particularly split PLIC3D is applied in numerically modeling draining from bottom of a cylindrical vessel and water-exit of a revolution body, from which evolutions of free surfaces are mainly illustrated.

重点在直角坐标系中推导了用斜面构造自由界面，使用分裂和不分裂推进的三维VOF方法：PLIC3D，以改善自由面求解精度；并用分裂的PLIC3D算法模拟了三维的柱形容器泄漏和旋成体出水问题，结果主要显示了它们的液面运动变化。

DRG co-cultured with sciatic nerve undergoing Wallerian degeneration for 14 days in vivo in serum free DMEM/F12,1 sciatic nerve segment was added into co-culture system at the first moment, the axons were strong and straight and could adhered to each other, and the number of axons dramatically reduced compared with that of DRG cultured alone in serum free medium.

分别在无血清和有血清的条件下将新生鼠的背根神经节和体内变性14天的大鼠坐骨神经段进行联合培养作为实验组，并以在相应条件下单独培养的DRG的轴突的生长情况作为对照组来观察比较轴突的生长情况。

Methods: Serum-free conditioned media of Schwann cell cultures from facial and sciatic nerves of neonatal and Wallerian degenerating segments in adult rats were individually collected and concentrated by ultra-filtration with molecular weight cut-off at 30 000 and 10 000. The growth activities of FMNs in vitro were determined by means of MTT assay under the condition of serum-free medium added with different components of concentrated SC-CMs.

收集1～4代大鼠沃勒变性段和乳鼠面神经及坐骨神经SC体外无血清条件培养液，超滤浓缩，测定分离纯化的FMN细胞在含不同来源的SC分泌的可溶性物质的条件培养液中的生长活性。
