The roundness tester is a highly precision instrument that is wildly used to measure the rotary work piece in mechanical industry. The aged roundness tester was astricted by the technique condition of that time, so its way of measurement is not at all advanced. Because these roundness testers have been used for a long time, they have a highly failure rate and their accuracy can not be insured.

圆度仪是机械工业中应用最广泛的检测回转体零件圆度误差的高精度仪器，由于老式的圆度仪受当时技术条件的限制，评定方法落后，再加上这些圆度仪的使用时间较长，使用时仪器的故障率一般都较高，测量精度也不能保证。

The results of continuous experiments with BAF show that: the short nitrification occurs when the Qair/Qinfluent ratio is 4:1 with NO_2~--N accounting for 72% of NOx--N; the suitable recirculation rate is 200%; the ratio of external acetate dose to NH4+-N concentration is 2:1 attributing to the short nitrification; BAF needs being backwashed when the headloss increases to 6 cm every 17~20 days; in the water reuse context, 98.7% water yield can be obtained.Lastly, the long-term operation of SBR-BAF system indicates it can treat the wastewater efficiently.

BAF反应器连续流试验结果表明：最佳气水比为4：1，硝化类型以短程硝化为主，NO_2~--N占到NOx--N的72%；综合考虑对TN的去除率和动力消耗，最佳回流比为200%；最佳缺氧/好氧容积比为3：5；由于短程反硝化较全程反硝化碳源需求量低，在BAF反应器进水NH4+-N 40mg/L左右的情况下，乙酸钠投加量为80mg/L以COD计设定水头损失达到6cm时进行反冲洗，随水温不同，反冲洗周期为17~20d，产水率为98.7%。
