生物体对环境(包括外环境和内环境)信号变化有极高的反应性。如细菌趋向营养物的运 动,视觉细胞对光的感觉,饥饿时激素信号使燃料分子(feul molecules)如糖、脂肪、蛋白质 等释放内部能量,生长因子诱导分化等都是典型的例子。细胞对外界刺激的感受和反应都是 通过信号转导系统(signal transduction system)的介导实现的

body. These organs can be classified functionally nto two main groups. The primary lymphoid organs provide appropriate microenvironments for the development and maturation of lymphocytes. The secondary lymphoid organs rap antigen from defined tissues or vascular spaces and are sites where mature lymphocytes can interact effectively with that antigen. Blood vessels and lymphatic systems connect these organs, uniting them into a functional whole Carried within the blood and lymph and populating the Macrophage Interacting with

MATLAB语言是美国 Mathworks公司研制开发的大型计算软件,自1985年问世 以来,特别是1993年4. x Windows版本的出现,使得 MATLAB语言的使用获得了巨 大的发展。它的强大的矩阵处理与运算功能、丰富的图形绘制能力深受用户的青睐 控制领域的研究者与工程技术人员对此给予了极大关注,国际上众多的知名学者在 此基础上先后开发出一系列的相关工具箱( toolbox),如控制系统工具箱( Control System Toolbox)、神经网络工具箱( Neural Network Toolbox)、系统辨识工具箱 ( Systerm Identification Toolbox)、最优化工具箱( Optimization Toolbox)、鲁 棒控制工具箱( Robust control toolbox)等,以及集成在 MATLAB上的面向结构图的 系统分析平台 Simulink。从而使得 MATLAB的功能得到了全面提高,几乎覆盖了控制 领域各个硏究分支
