例句与用法

  • Experimental constants include : ambient temperature 291k ~ 301k , rh 15 % ~ 21 . 2 % , wind velocity 3 . 2m / s at the nozzle position and horizontal to the spray fan , others are same as the fore experiment . the tendency of the two experiments results is consistent with the tendency from simulation . that indicate the improved shield spray is better than the original shield spray in reducing spray drift , and also more better than conventional spray without shield
    风洞试验参数:喷雾药液为含1 bsf的水溶液,风速1 . 4m s ,风向垂直于喷雾扇面,温度281k 288k ,相对湿度rh9 20 ;室内试验参数:喷雾药液为含2 bsf的水溶液,喷头处风速为3 . 2m s ,风向平行于喷雾扇面,温度291k 301k ,相对湿度rh15 21 . 2 ;分别在喷头下风向喷幅外的空中和地面布点收集飘失和飘移沉积的雾滴量,作为评价减少雾滴飘失效果的指标:试验结果表明:改进后的罩盖喷雾减少雾滴飘失的效果好于双圆弧未开口罩盖喷雾,常规无罩盖喷雾的雾滴飘失量大于开口罩盖喷雾。
  • The calculated mean diameter , mean square - root diameter , mean cube - root diameter and liquid water content are all well matched with the observational results ; in the paper two examples have been analyzed by using the seeding region data and the possible affecting region data in leeward region . it is found that f - 100 , 2dc , and 2dp ' s particle concentrations increase in leeward region , but rising extent is different , which is likely to be due to difference of seeding effect time
    拟合值和观测值吻合的较好,计算出的平均直径、均方根直径、均立方根直径和粒子浓度与观测值也比较吻合;本文对两组个例的催化影响区域及可能采集到相应值的下风方区域进行了分析,催化下风向影响区的f - 100 、 2dc 、 2dp的粒子浓度比背景值都有所增加,但是增加的幅度不同,应该是催化响应时间的原因。
