There was no relationship between UOC and UNa .

UOC及尿钠排出两者间无直接关系。

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。

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。

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。

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；
