The fluctuation characteristics of liquid slug length in the downward inclined pipe with a large range of gas and liquid velocities were investigated on the basis of fractional theory of air / water slug flow 摘要利用非线性分析技术中的分形理论在较宽的流速范围内对下倾管中空气水段塞流的液塞长度波动特性进行了研究。
The results indicate that the distribution of liquid slug lengths can consist with the log - normal distribution , and the fluctuation of liquid slug lengths is a chaotic vibration which is sensitively dependent on the initial conditions and has permanence properties 结果表明,下倾管中段塞流的液塞长度符合对数正态分布,其波动是对初始条件敏感的混沌振荡,且具有持久性。
In the next generation of wireless communication , the base station antenna should have these functions : integration of different diversity methods to release multi - path fading , beam - downtilt to reduce co - channel interference , beam - forming to optimize coverage 在设计新一代移动通信基站天线时,应使天线能综合各种分集方式进行天线分集以消除多径效应,具有波束下倾以减少同频干扰,能波束赋形以实现优化覆盖。
So it is hope to find gently - biodegradation - oil of pingdiquan formation at declination direction of slope . the paper also points out the next aspect of exploration . east - slope of jimusaer depression and the dropped side of jimusaer rupture are the next advantageous aspect of exploration 指出吉木萨尔凹陷东斜坡及吉木萨尔断裂下盘是下一步勘探的有利方向,降解沥青(或稠油)与岩性共同形成封堵,对油气富集起封堵作用,在斜坡下倾方向有望发现第二期的受生物降解程度弱的油藏。
