experimental constant造句

• The captured droplets weight is regarded as evaluating indicator . experimental constants include : ambient temperature 281 - 288k , rh 9 % ~ 20 % , wind velocity 1 . 4m / s and vertical to the spray fan
  风洞和室内试验比较了结构改进前后的罩盖喷雾减少雾滴飘失的效果，并和常规无罩盖喷雾对比。
• 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。
