The results of the micro-structures showed that the cells of fresh and calcium-hardened carrots are isodiametrical and polyhedral and the cell walls are smooth. When heated at 110℃ and 121℃ for 10 mm, the cells of calcium-hardened carrots were still maintained. The intercellular spaces of carrots without calcium-hardening were lost when they were cooked at 121℃ for 30 min and the structure completely collapsed.

在微细构造方面：新鲜及钙硬化之胡萝卜细胞呈多角形且细胞壁平顺少有皱摺，在110℃及121℃烹煮10 min仍可维持完整细胞形状；未钙硬化之胡萝卜於121℃烹煮30min后细胞间隔消失，组织完全崩塌。

The identification of the PWL model includes two steps. First, obtain the polyhedral partition of the regression space based on a new fuzzy G-K clustering technique. In each cluster, the nonconsecutive parts of the input and output data that correspond to one of the local linear sub-models can be used to obtain the system matrices.

放松了混杂PWL系统辨识对切换已知要求的限制，在子模型辨识的同时考虑基于模糊G-K聚类的多区域划分，使用本质不连续的测量数据辨识PWL状态空间模型，并将辨识得到的状态序列变换到统一的状态空间内。

In Chapter 2, we consider the error bound and the auxiliary problem algorithm for the generalized linear complementarity problem over a polyhedral cone: First, we give an absolute and a relative global error bound for GLCP and nondegenerate GLCP, respectively, and then we explore the properties of the solution set of the problem, based on which we establish another absolute and relative error bound for GLCP which is much exacter compared with the result above.

第二章主要研究了闭凸锥上广义线性互补问题的误差界及基于其上的一个求解GLCP的辅助问题算法：(1)给出了GLCP的全局绝对误差界和在有非退化解时的全局绝对误差界及其相对误差界；(2)对GLCP的解集结构进行了探讨，并利用得到的结果给出了GLCP的另一个全局绝对误差界和相对误差界估计；(3)我们提出了一个求解GLCP的辅助问题算法，并证明在适当条件下该算法具有全局收敛性。
