The determination of minimum allowable inlet temperature should be based on the allowable shutdown time, rheology and yield behavior of crude oil, temperature condition, start-up pressure and flow rate to do a quantitative calculation and combine with the results of site test. 综合分析结果表明,含蜡原油管道最低允许进站温度,应该根据允许停输时间、原油流变和屈服特性、温度条件、启动压力和排量等条件定量计算,并与现场试验相结合来确定。
Therefore, it is an urgent task for us to research, find and use an optimal preservation means to minimum the damage of warm ischemia in the course of preservation, prolong the preservation time and increase the utilization rate of renal donor. 因此,研究、寻找和使用最佳保存方法,以降低移植肾脏的热缺血损伤,延长离体肾脏保存时间,提高供肾的利用率已成为我们面临的一项亟待解决的难题。
