梁可视为平面应力状态，先按图示尺寸划分为均匀的三角形网格，共有8×10＝80个单元，5×ll＝55个节点，坐标轴以及单元与节点的编号如图。将均布载荷分配到各相应节点上，把有约束的节点5l、52、53、54、55视作固定铰链，建立如图所示的离散化计算模型。(The beam can be regarded as a plane stress state. Firstly, the beam is divided into uniform triangular meshes according to the graphic size. There are 8*10=80 elements, 5*ll=55 nodes. The coordinate axis and the numbering of elements and nodes are shown in the figure. The uniform load is distributed to the corresponding nodes, and the constrained nodes 5l, 52, 53, 54 and 55 are regarded as fixed hinges. The discrete calculation model shown in the figure is established.)

针对三种不同脉冲编码信号的模糊函数进行了设计。矩形脉冲信号，线性调频信号，相位编码信号。(The fuzzy function is designed for three different pulse coding signals.Rectangular pulse signal, linear frequency modulation signal, phase coded signal.)
