渐变段 meaning in Chinese
transition region
transition section
Examples
- Pavement - width transition marking
路宽渐变段标线 - Transition tamper length
渐变段变换段长度 - Analysis on the characteristic of cold complex cavity with gradual transition of various obliquity
渐变段倾角对渐变复合腔特性影响的分析 - For example , when the design flow of upward of the peace bridge of upward of the east - one main canal is 45m3 / s , the actual flow quantity is 23 . 8m3 / s on the 30th of september in 1989 , the water level of the transition region terminal of the mouth of hao wan flume of the east - one main canal had gained the design level of 4 . 3m , and the level between downstream and shang tian yuan tunnel was generally higher . it says that the actual discharge capacity now is only about 24m3 / s which is half of the design value . this not only make the benefit of the irrigation district abnormal , but also greatly hinder the economic development of the irrigation district , and lead to the canal run frequently at small flow , high water level , lengthen the discharge duration
如东一干渠上段太平桥以上设计流量45m ~ 3 s ， 1989年9月30日实测通水流量23 . 8m ~ 3 s时，东一干渠郝湾渡槽出口渐变段末端水位已达到设计水位4 . 3m ，其下游至上天院隧洞水位也普遍偏高，即东一干渠上段目前仅能通过流量24m ~ 3 s左右，只有设计值的50左右，不仅使灌区效益得不到正常发挥，严重阻碍了灌区范围内的经济发展，而且使渠道经常处于小流量、高水位运行，延长了次通水时间，大大增加了渠道工程的安全管理难度。 - In this dissertation , the performance of linearly tapered fin - fed slot antenna ( lwsa ) is discussed in theory , simulation and experiment . the radiation pattern characteristic influenced by changes of antenna ’ s dielectric material , tapered shape and dimension is studied detailedly . though the tapered slot antenna design is very important , a good waveguide - to - finline taper transitions is also needed because they could not thought over separately
本文主要采用理论分析、数值仿真和实验等手段对线性渐变槽天线的特性进行了研究,分析了介质材料、天线渐变段以及天线尺寸对天线方向图的影响,分别设计了天线罩、线性渐变槽天线以及天线的馈电结构。
