upper shed
Examples
- Unscrew body halves using open end or adjustable wrench on flats provided
采用预备好的平头上开口或可调节扳手拧下一半阀体上的螺丝。 - The edged - based fem in combination of pml is applied to compute the radiation of an open waveguide in infinite plane . the calculated radiation patterns are in agreement with that obtained by analytical method
本文应用矢量有限元和pml分析了无穷大接地平面上开口波导的辐射特性，与理论近似方法对比完全符合。 - Some of the more pertinent variables include the relative wind , the type of terrain onto which the flammable fluid has drained , the fuel distribution , the location of the fuel spillage within the aircraft , the number of structural openings ( designed or crash produced ) that meter the inflowing air available for an internal fire , and the amount of fuel available to spill
某些更重要的因素，包括相应的风速，油料泻溢的地面状况，油料的分布，飞机内油料外溢的位置，根据结构上开口的数量（设计上的与坠机造成的）来计算灌入的空气是否会造成内部火灾，以及可能外泻的油料量。 - 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
本文采用导流法在双圆弧罩盖上开口，利用fluent模拟分析和比较罩盖喷雾流场，并模拟该流场下的雾滴运动轨迹来分析雾滴的飘失性，模拟结果表明：结构改进后的罩盖喷雾流场得到改善，其减少雾滴飘失的效果好于原罩盖，更优于常规无罩盖喷雾。
