Branch channel flow 分汊水流
In order to relatively hold up mud and sand on the spot and control deposition , we should control head channels , branch channels , main channels on slope surface comprehensively 通过采用沟头、支毛沟、干沟及坡面的综合治理,实现相对就地拦截泥沙,从而达到控制库坝淤积的目的。
In addition , the hydrological data reorganization of branch channels of irrigated area and the calculation of water quantity and water rate can be done using this system 另外,本系统也可以进行灌区支渠水文资料整编以及水量、水费计算。本软件系统无论专业性还是适用性都很强。
For the low water head water control project at a branching channel , its flood discharge capacity is related not only with the total discharge width but also with the discharge width ratio of the two branches 摘要位于分汊河段的低水头枢纽,其泄洪能力不仅与枢纽的总泄流宽度有关,而且与两汊泄流宽度之比有关。
A new design of fractal branching channel net for cooling of electronic chips is studied . based on the generation of a fractal branching net , heat transfer and the required pumping power for fluid flow in fractal microchannels and the parallel channels are compared 论文最后介绍了一种分形微管道网络,在给出其构造过程的基础上,利用有限元法将其传热能力、所需泵送功率与平行微管道网络进行了比较。
This system is of great specialty and practicality . its application tolo trunk channels and more than 70 branch channels of qingtongxia has proved that this software is reliable , practicable , common , scientific and reasonable . it has a good popularization value 通过在青铜峡10条干渠和70多条支渠上的应用,已充分验证了该软件系统的可靠性、实用性、通用性、科学性和合理性,具有很好的推广应用价值。
Climatic mean map , it is further confirmed that it s a good approach to retrieve the equatorial zonal circulation by using the ir indicate ascending branch and wv indicate descending branch channels . the definition of the index of zonal circulation with the olr and fwv are presented and the 17 years mean annual and seasonal equatorial circulation are drawn . the climatic characteristics of the equatorial zonal circulation are analyzed in detail . consequently the fore results of the other observation are corrected 通过波耳兹曼公式换算得到的6 . 7m水汽辐射通量密度,以便于与olr比较与ncep再分析的500hpa的年气候平均图进行比较,分析其异同,进一步证明了用卫星观测的红外,水汽双通道olr表示上升运动, fwv表示下沉运动去反演纬向垂直环流是一个极好的途径。
