縱觀有限元分析技術的發展，目前大多集中在建立良好的用戶界面上的研究仍存在許多應用上的局限性，其中對任意剖面上可視化的研究仍處于方興未艾的階段。要實現任意剖面上可視化處理，必須先將得到的有限元計算結果進行再處理，因此在演算法上分為兩部分：求任意剖面上物理量值的演算法及二維等值線演算法。前一部分以彈性力學中「任意斜截面的應力」為理論基礎，利用線性插值方法得到截面與單元棱邊的交點坐標及交點物理量值；在此基礎上；根據已得到的單元及節點序號表、應力應變物理量表，總結出一種基於有限元剖分網格的快速生成二維等值線的演算法。Fieldbus is a kind of communication network which is a whole digitial communication multi _ embranchment data bus between intelligential field device and auto _ system. control system based on pcs ( fieldbus control system ) is a new kind of system which connect field control unit, field monitor unit, operation unit, communication interface uint with databus. lt integrates computer technology, communication technology and process cnotrol technology to adjust to demand of high standard productive control and enterprise management. lt developments and follows the advantage of traditional instrument control system and computer central control system and make up for their disadvantage so that it is applied in different industrial cnotrol area
