Therefore , it means much to develop the digitizer based on pxi bus . to establish the whole scheme of digitizer , the design studies the implements of different products based on many articles and product descriptions , and compares the advantages and disadvantages comprehensively 本设计在参阅大量文献和产品资料的基础上,对现阶段数字化仪产品作了的充分分析,多方位对比了各种实现方法的优缺点,并最终确定了pxi总线数字化仪的总体方案。
The oil field , named daqing , spent much money on software and computer equipment - - - - sun workstations . then they spent a few years , finished only little part of the work . the main aim was at vectorizing the well log curves applying foreign software 目前通常采用数字化仪或国外矢量化软件来完成这一工作,但是速度较慢,效率较低,例如,大庆油田曾经为了矢量化部分图纸,购买了矢量化软件,并购进大量sun工作站,花了几年时间才只是处理了一部分。
