研究的水质COD在线检测系统是根据朗伯-比尔定律来测试水样COD浓度,系统采用双光路设计,并选用可变光程流通池来满足在不同水体测试的要求。通过本系统检测得到的5组水样COD浓度,对系统测试COD浓度值与已知实验室化学法COD浓度值进行了二者的数值偏差及误差分析。实验结果表明,两者的最大偏差值约为7.93,最小偏差值为0...
Within a physical processor (the processor package that inserts into a processor socket), the NUMA node assignments (logical clustering) reflect the physical connection of CPU cores to integrated memory controllers and the associated DRAM. A processor socket is often represented as just one NUMA node...
