在两次计量校准间隔期内，采用测量过程控制方法保证测量仪器的精度。
Measurement Process Control is adopted for a measuring instrument to guarantee its precision in the interval of two calibrations.
该方法是一种基于信号采样时钟速率的全数字化处理过程，其同步精度可达到信号采样间隔的1%以上，且便于FPGA或DSP实现。
The method is a fully-digitized process at the sampling clock rate, so that it can be conveniently implemented by FPGA or DSP, whose synchronization precision can reach 1% of the sampling interval.
借鉴LOD思想，利用多种采样间隔获得不同精度数据网格。
Using the idea of LOD for reference, obtain diverse data grids of various precisions by different sampling intervals.
