查询词典 fluid

The experiment results shown that: 1 the smaller the pH value, the smaller the use amount of alkaline metal and the alkali earth metal electrolyte demulsifier, when the pH value was 3, the waste fluid could be demulsified no any demulsifier and the use amount of the demulsifier did not increase remarkably along with the wiredrawing fluid concentration increased. 2 Using polymeric ferric sulfate as coagulant demulsifying, when the pH value was 8.4, the best adding amount was 40 mL per liter wastewater and the best precipitation time was 4 hours. Then the COD concentration was 480 mg/L, reaching the water quality requirements to enter the sewage treatment plant.

objective:to explore the method of ultrasonography in the diagnosis of oligohydramnios in late pregnancy,the association of olignophdramnios with pregnant complications and its effect on perineonate.methods:the clinical data in 84 patient with oligohydramnios from january 2004 to december 2006 in our hospital were collected,and 100 patients with normal amniotic fluid volume selected randomly served as control at the same time.the complications of pregnancy and adverse perinatal outcomes were analysed.results:afi method was much better than afv in diagnosis of oligohydramnios by ultrasonography.the combination of both methods could obviously improve the diagnostic accuracy of oligohydramnios.oligohydramnios could cause pregnant complications,the rate of cesarean section,fetal distress,asphyxia neonatorum and meconium -stained fluid improved significantly.conclusion:oligohydramnios in late pregnancy can cause adverse effect to perineonate,it is a dangerous omen to perineonate and need to be done immediately.ultrasonography is a dependable diagnostic method of oligohydramnios in late pregnancy.

目的：探讨超声诊断晚期妊娠羊水过少的方法，羊水过少与妊娠并发症的关系及对围生儿的影响。方法：收集我院2004年1月~2006年12月住院分娩足月妊娠产妇超声诊断羊水过少者84例，与临床符合率相比较，同时随机抽取同期在我院住院分娩的羊水量正常孕妇100例作为对照组，两组妊娠并发症及围生儿情况进行比较。结果：超声诊断羊水过少afi法优于afv法，两种方法结合可明显提高羊水过少的诊断准确率，羊水过少易伴发妊娠并发症，且妊娠晚期羊水过少孕妇剖宫产率及胎儿窘迫、羊水粪染、新生儿窒息的发生率明显增加，差异均有显著性。结论：妊娠晚期羊水过少会给围生儿造成不良的影响，是危险的征兆，需及时处理，超声检查是产前诊断羊水过少的可靠方法。
