The organophosphorus pesticide wastewater was treated by sequencing batch reactor(SBR). The results of full scale unit show that SBR has characterized by simple structure,easy and convenient operation,and higher removal rate of COD and organophosphorus. 采用 SBR生化法处理有机磷农药废水 ,生产规模试运行结果表明 ,SBR生化法具有装置结构简单、运转灵活、操作方便、COD和有机磷去除率高等特点。
State-of-the-art accuracy of .25% of full scale for reliable testing of all types of backflow prevention assemblies. 最新技术的精确度，达全量程的0.
absorbance unit full scale 满刻度吸光度单位
Ranges shall be selected such that the normal operating temperature indication is approximately 50% of full scale. 量程应有所选择，使得正常的操作温度指示大约是满量程的50%25。
Under circumstance of pulsant (fluctuant) pressure, prescribed maximum of measured pressure is one-third of full scale of the selected gauge. 在脉动（波动）压力的情况下，被测压力的最大值选用压力表满刻度值的二分之一。
