1) non-precipitation
非降水
1.
for Shenzhen metro Da~Ke running tunnel engineering,key construction techniques of Shenzhen metro Da~Ke running tunnel non-precipitation engineering and corresponding countermeasures by means of spot testing,measuring,centrifugal model experimentation and numerical simulation are expatiated roundly.
针对深圳大—科区间隧道软弱富水的地质条件、设计断面变化多样以及复杂而严格的边界限制等特点 ,全面地阐述了大—科区间非降水施工的关键技术以及在现场试验、监测、离心模型试验和数值模拟分析指导下所采取的对策措施 ,并反映了实际工程所取得的良好施工效果。
3) non-precipitation parameter
非降水参数
1.
Assessment of CLIGEN non-precipitation parameters on the Loess Plateau;
CLIGEN非降水参数在黄土高原的适应性评估
4) non-precipitation technique
非降水技术
5) Non-precipitation echo
非降水回波
1.
Non-precipitation echos were few Researched with restrict to detectivetechnique and data, because it is too weak to be detected by traditional radar.
这种回波的产生可能是由于在近地面处有逆温,逆温中潮湿的地面使水汽压随高度变化很大,导致了折射指数随高度变化很大;也可能是近地层湍流或者上空有云回波,由于多普勒雷达灵敏度很高,往往产生非降水回波,其多普勒速度特征反映了雷达站周围环境风场的结构。
2.
Non-precipitation echo from radar such as ground objects echo and super refraction and so on are important to explore quantitatively precipitation and the other products.
地物和超折射等非降水回波是影响雷达定量探测降水和其他产品的重要因素,利用降水和非降水回波反射率三维结构特征可以对雷达数据进行质量控制。
6) excessive precipitation
非常降水量
