查询词典 rainfall

In this paper, the spatial distribution of soil erosion intensity on a long and straight cultivated slope was studied using 137Cs measurement and wavelet analysis. The results showed that there existed an fluctuant period of soil erosion intensity with 142m along 4 transects downslope, which suggested that the intensity of soil transporting changes between weak and strong alternately downslope during the impact of long-term erosive rainfall.

本研究通过采集开垦近100年的黑土直型坡耕地的土壤样品，利用137Cs示踪技术，结合小波分析方法，研究了长坡长直型坡耕地50多年来土壤侵蚀强度的空间变化规律，结果显示4个断面顺坡方向上的坡面侵蚀强度均存在着坡长为142 m的强弱交替变化的波动周期，这反映了长坡长直型坡土壤在长期的降雨侵蚀过程中，泥沙沿坡面输移的强弱交替变化。

A scientist measured rainfall and discharge in the seine drainage basin for a period of three years.

有一个科学家测量了塞纳河流域盆地三年内的降雨量和流量。

Fully raising rainfall use efficiency of farm-land is the basis of high efficient utilization to limited water in dry-land farming.

充分提高农田降水利用效率是旱地农业中有限水高效利用的基础。

Therefore, in order to ensure the transmission quality, reliability and economical efficiency, we must master the rainfall attenuation influence of earth station setting areas accurately while the designing the earth-space satellite communication links.

因此，在设计地—空卫星通信线路时，为了保证通信系统传输质量、提高可靠性及经济性，就必须要准确地掌握地面站设置区域的降雨衰减所产生的影响。

Since 1992, the Russian company Elate Intelligence Technologies, Inc. has demonstrated its ability to radio-control rainfall on demand over an area of 200 square miles.

自1992年以来，俄罗斯公司elate情报技术，公司已表明，它有能力的无线电控制降雨对需求的面积200平方英里。

The black soil in Northeast China had a stable soil structure, and raindrop beat was the dominant factor resulting in the development of crust. During the process of rainfall, no obvious eluviation was observed.

东北黑土结构稳定，雨滴打击是其结皮发育的主导因子，降雨过程中未发现明显的颗粒淋移现象。

The results were showed as following: The growth of fruit size appeared to be a markeddouble- peak curve and was affected by the rainfall, Thedifferences in endosarc were decided by changes of citric acid and soluble sugar content which showed opposite variety.

结果表明：果实纵横径生长动态均呈双高峰曲线，且与降雨量密切相关，内质的差异主要体现在柠檬酸和可溶性糖的变化上，菲诺的柠檬酸含量一直上升，而尤力克的柠檬酸含量在采前有下降趋势。菲诺的可溶性糖积累逐渐增多，而尤力克不断下降。

The results showed that erectness of coupling pattern between upper-layer jet and low jet and a divergence area, which came forth in right of upper-layer jet provide favorable surrounding conditions. The most intensive moisture convergence, the strongest ascending movement and the most instable convection stratification all occurred in the rainfall center. The rainstorm occurred at the warm and wet side of the negative value center of the moist potential vorticity and relative MPV, which had certain indicative significance for the forecast of rainstorm areas.

结果表明：高低空急流的优势配置，耦合形势的建立以及高空急流右侧的强辐散场的存在为暴雨的发生提供了有利的环境条件；暴雨区中上升运动和水汽辐合均大于周围区域，中低层为对流不稳定层结；暴雨区位于湿位涡和湿相对位涡负值中心附近偏暖湿气流一侧，对暴雨落区预报有一定的指示意义。

In the process of the land water circulation, rainfall and evaporation are both playing a quite important role.

摘要 在陆地水循环的过程，降雨与蒸发现象扮演著相当重要的角色。

Rainfall is one of the main reasons which evoke landslide.

边坡中降雨是诱发滑坡的主要原因之一。
