In related transportation news, the Waterways Resource Act ( WRDA ) is again back in conference.

另据相关消息, 围绕《水运资源开发法》 ( WRDA ) 的会议再次召开.

In this paper, the characteristics of wedge ring detector ( WRD) are introduced. The correcting method of the responding factor is discussed theoretically, and the experimented results are given.

本文介绍了楔环阵列探测器（WRD）的特性，理论上论述了WRD线性响应因子校正的方法，并从实验上获得验证。

The spatial variability of regional water requirement ( WR ) and water deficient ratio ( WRD ) are studied with geostatistics.

应用地统计学方法研究区域 需水量 和缺水率的空间变异性.

The CGH/ WRD system ( computer generated hologram/ wedge-ring shaped detector) were synthesized with CGH and CCD devices.

提出用计算机制全息图配合CCD器件制成具有楔环探测器功能的CGH/WRD系统。

Furthermore, it was necessary to investigate the mechanism of water resources demand ( WRD), the patterns of water using as well as the measures taken for effectively managing water resources requirements.

迫切需要对水资源需求的机理进行研究，研究科学的用水模式、水资源需求调控方式以及进行水资源需求管理的有效措施。
