| 1. | Application of profibus - dp in the communication to weishan ' s culvert - brake and dam in the yellow river 在位山引黄涵闸通讯中的应用 |
| 2. | Engineering geological problems of foundation pits of floodgates in the lower reaches of yellow river 黄河下游涵闸基坑的主要工程地质问题 |
| 3. | Bpnn is suitable for the soft measurement modeling for its advange of fitting functions Bp网具有较好的函数逼近及映射能力,适合涵闸流量软测量建模。 |
| 4. | In order to solve the turaoff facing yellow river now , we need supervise the flux by the long - distance measurement 为了更好地解决黄河下游河道断流的问题,有必要对引黄涵闸过流量进行远程监测。 |
| 5. | In many low head hydraulic structure , expecially canal system structure , we are used a dopting underflow energy dissipation 在众多的低水头水工建筑物中,特别是渠系建筑物中的涵闸下游,多采用底流消能。 |
| 6. | Also , it takes a rather long time in measuring the flux in the conventional way , which interferes the gate driver to control the sluice gate in time 另外,传统测流所用的流速仪法需较长时间,不利于下游涵闸管理部门根据调度快速调控。 |
