rain channel 中文意思是什麼
rain channel
解釋
水蝕溝-
Through examination of the recession limbs of the observed hydrographs, during periods with no rain and thus no surface runoff, one can determine the value of. for this catchment, a value of 0. 8 is obtained. the simulated subsurface runoff at each grid is routed to the outlets through a unit - hydrograph method for overland flow and the linear saint - venant equation for channel flow to get the discharge at xixian station
對所研究的流域而言，經過估算消退系數為0 . 8 .耦合著這兩種不同地下徑流機制的clm模型都可以計算出每個網格的地表地下徑流深，採用dag lohman 34 ， 35發展的匯流模型進行匯流由於是研究地下徑流，所以取每個網格的地表徑流為0 ，該模型採用單位線計算坡面匯流線性聖維南saint - venant equation進行河道匯流 -
In chapter 5, the main channel impairments, such as rain attenuation, clear air absorption and distortion due to the hpa, are covered and approaches to overcome them are suggested
從雨衰、大氣的吸收以及高功率放大器hpa等方面對lmds系統的性能惡化等方面做了仔細的研究，並針對這些不同的情況，提出了一些建議性解決方法。 -
Earlier this year, airport officials resurfaced the runway used by the tam flight, but they said workers had not yet cut grooves into the pavement to help channel rain water
今年年初，機場人員說會將tam飛機所使用過的跑道重鋪，但是他們說工作人員尚未將跑道上的凹槽改為導雨水溝。 -
This paper comprises two parts : radar clutter simulation and adaptive moving target indication. in the former part, we analyse the generation mechanism of single - channel radar correlated clutter and illuminate the simulated modeling way of rayleigh, log - norm, wei bull, k - distributed clutter with special power spetrum. all these models are used into the practical simulation of ground clutter, cloud - rain clutter and chaff jammer according to their features
在雷達雜波模擬部分分析雜波的產生尤其是單通道相關雷達雜波產生的機理，具體闡明了在指定雜波功率譜情況下，幅度服從瑞利分佈、對數正態分佈、韋伯分佈和k -分佈的雜波的建模與模擬方法，並根據不同分佈的特點，將其應用到地雜波、氣象雜波和箔條干擾的模擬中。
