According to the structural feature of parallel single disk gate valve, the strength and rigidity of body will be calculated with finite element method, and with cylindroid shell theory.
根据主闸阀结构特点，分别用有限元法和椭圆柱板壳理论公式计算了阀体的强度与刚度，并进行了分析对比，同时对闸板的刚度进行了校核。
With this method, a new storage system with 16 hard disk is realized by keeping the present computer hard disk design, adding a CPLD chip and three 74HC16245 gate drivers.
该方法融合现有的计算机硬盘设计方法，不改变硬盘的原有工作模式，只是增加一片逻辑芯片和三个74HC16245驱动器，便可实现16个硬盘的存储方式。
