UOC

COC concentrations reached their maxium value 1 day later than DOC and UOC, and is the most active part in the DOC.

培养系统中COC浓度达到最大值的时间比DOC和UOC要晚一天，其是总溶解有机碳中最有活性的部分。

During 1~ 5 days of age, their values of UOC and urine sodium ( UNa) were measured every 12 hours, and their urine volume ( UV) was collected daily.

日龄1～5天时，每12小时测UOC及尿钠，每日统计尿量。

Objective: To evaluate the significance of fluid therapy in premature infants using a drop of urine for measuring urine osmolarity ( UOC) value with refractometer.

目的：用一滴尿折射率方法测定尿渗透浓度（UOC），评价其在指导新生儿特别是早产儿液体治疗中的价值。

Liquid distribution curves of ERI and BL gas/ liquid distributor are gentle as well. As for pressure drop, ERI gas/ liquid distributor is the lowest, UOC is intermediary, and BL is higher;

ERI型和BL型气液分配器的液体分配曲线平缓，在压力降方面ERI型最低、UOC型居中、BL型较高；

Tne degree temperature distribution asymmetry of ERI and BL quench box are both lower than that asymmetry of UOC quench box. Pressure drop of ERI quench box is the lowest, UOC is intermediary, and BL is the highest.

ERI型和BL型急冷箱的温度分布不均度均比UOC型的低，在压力降方面ERI型最低，UOC型居中，BL型最高。
