double drift 中文意思是什麼
double drift
解釋
二星流-
A slot was cut in the back plate of the double - foil shield to improve the flow field with air diversion method. the flow field and droplets trajectory near the shield are simulated in wind tunnel by fluent software to analyze the wake flow affecting the spray drift. from simulation, the improved shield spray in reducing drift is better than double - foil shield spray and conventional spray in six types of wind velocity
本文採用導流法在雙圓弧罩蓋上開口，利用fluent模擬分析和比較罩蓋噴霧流場，並模擬該流場下的霧滴運動軌跡來分析霧滴的飄失性，模擬結果表明：結構改進后的罩蓋噴霧流場得到改善，其減少霧滴飄失的效果好於原罩蓋，更優于常規無罩蓋噴霧。 -
The detecting accuracy of the beam drift would be improved, as a high performance acoustooptic modulator modulates the frequency of the laser beam drift signal far away from the power frequency, the double power frequency and high frequency noises
具體包括: 1 .利用聲光調制器將光束漂移量信號調制到遠離工頻及其倍頻干擾和高頻噪聲的頻帶段，以期提高光束漂移量的檢測精度。 -
Graded doping is adopted in both sides of the junction ( double graded doping ). this results in a strong ( drift ) electric field throughout the whole active layer. this field will accumulate minority carriers effectively and the whole internal quantum efficiency is increased
漂移場的形成是通過mbe技術，在結的兩側都採用梯度摻雜（即雙梯度摻雜） ，從而在整個有源層都建立起一個強的（漂移）電場，有效地利用載流子在電場作用下的漂移作用收集少數載流子，使得總內量子效率得以提高。 -
In this design, the double graded doping solar cell accumulates the minority carriers with the drift field, which is located at the whole graded space. this means that the accumulation of minority carriers doesn ’ t depend on the above conditions
採用與眾不同的通過在p區和n區都採用梯度摻雜這樣一個所謂雙梯度摻雜，在整個有源層獲得高達104v / cm的漂移電場。 -
To take an actual example, the triple pipe method has been adopted to consolidate the surrounding soil by rotary shot grouting pile and swaying shot diaphragm wall in the construction of vertical shaft and access drift of running tunnel from martyr ' s park to dong shan kou station in no. l line of guangzhou metro. it turns out that this method has met the double effect of both construction support and waterproof
作為施工實例，在廣州地鐵一號線烈士陵園至東山口區間隧道的豎井及聯絡通道施工中，採用三重管法對周圍地層實施了旋噴樁和擺噴墻加固，達到了施工支護和防水止滲的雙重效果。
