Besides, because of diversity of biochip image, the shape of some spots can not be uniformly circular. Solved the problem of coarse segmentation and modification of deflexion angle, a method of tracking local spots profile—Template snake model has been proposed in the paper, it can recognize the target from roughness to precision step by step, so to guarantee the precision and efficiency of segmentation.

此外，由于生物芯片多样性特点，某些芯片样点外形并不一定是简单的孔径问题，本文在比较彻底地解决了样点粗分割及偏转角校正后，提出了局部区域的样点轮廓跟踪方法——Template snake模型，实现由粗到精的宏状多目标分层识别策略，既保证了样点分割的正确率，又加快了执行速度。

Fourth precision solution can be derived from two grid sets solution with a second precision central difference scheme by Richardson extrapolation. It reduces the amount of calculation. Uncertainty is determined from the discretization error analysis. A finer grid calculation is made to validate the extrapolation scheme.

对于2阶精度中心差分格式的2套网格数值解，用Richardson外推法可以得到4阶精度的解，其工作量比直接求解4阶离散方程的工作量减少许多；对于计算中的数值不确定度，用该方法分析了离散误差，并用逐次加密网格的方法探讨了外推法的合理性。
