Several calculation methods of electric potential are given for the conductor in electric fields to expand addition method , to discuss the problem of electric potential of complex conductor in electric fields , so we can solve the problem of conductor in many complex electric fields 摘要就静电场中导体的电势计算方法叠加法加以扩充,对静电场中复杂的导体的电势问题进行了分类讨论,由此解决了很多复杂的静电场中的导体的电势问题。
The digital correlators of the two structures are designed with the foundation series 3 . 1 xlinx design tools software . the classical structure emphasizes on the design of the adder , whose general form and 3 - 2 compressor structure are designed and analyzed . in this system , an express addition method is put forward , and its synthesis performance proves that it is superior to the two structures mentioned above 文中利用xilinx公司的foundationseries软件,详细设计了两种结构的数字相关器,经典结构的数字相关器以加法器的设计为重点,设计并仿真了一般结构和3 - 2压缩结构的加法器,针对本系统文中还提出了一种快速计算加法的设计思想,综合后比前两种结构在性能上有明显的提高;修正结构的数字相关器是基于模块化的思想设计实现的,并以一个码元的不同延时点为例,详细分析了相关器的性能。
Fourthly , set up the price theory model of the mould . combining the book of mould valuate method consult manual " and some actual conditions of mould factories , five kinds of methods : weight method ; man - hour method ; unit ' s weight method ; man - hour addition method ; similar comparative method are constructed and appraised 另外还建立了一些常用加工方法工时计算的数学模型;然后剖析了《模具计价办法参考手册》中的两种估价方法,工时法和重量法;针对覆盖件模具的特点,根据成都某模具厂的经验建立了单位重量法和工时累加法的数学模型。
