  1. While the speed is very large, the fuel - air mixing behind the airstream is decreased and the span that the fuel flow in the second combustor is reduced, so the combustion efficiency is decreased, h ) if the fuel streams impinge with the airstreams directly at the air - inlet exit, it make against increasing the combustion efficiency, i ) increasing air - to - fuel ratio within proper range can increase the combustion efficiency

    增加燃氣噴射速度有利於增強迴流區強度，頭部燃燒溫度上升，但速度太大則會減弱燃氣同空氣在進氣道下游的摻混燃燒，減少燃氣在室內停留時間，燃燒效率降低； 8燃氣射流與空氣流在進氣道出口直接撞擊不利於燃燒效率的提高； 9在適當范圍內增大空燃比能顯著提高燃燒效率。
  2. This the production thread application plc carries on procedure control, and realizes to crowd out machine owner ' s electrical machinery and synchronization towing the mechanical and electrical machine is transferred fast ( ly ), and the installation has the good man - machine interface, and all technology parameters all can be set up and show by way of touching the screen, and producing to consult the menu, the order name was formerly fixed in the input, and whole production line just can be according to primary pipe specifications and speed production fixing every time ; cutting the function voluntarily fixed long ( ly ) cuts, and a pattern head temperature is controlled to use the import intellect warm accuse table ( making the temperature deviation within ), therefore having pledged the quality of tube

    本生產線採用plc進行程序化控制，實現擠出機主電機、牽引機電機的同步調速，並設置有良好的人機界面，所有工藝參數均可通過觸摸屏進行設置和顯示，每次生產只需查閱菜單，輸入原先設定序號，整條生產線就可按原設定的管子規格和速度生產；切割機能自動定長切割，模頭溫度控制採用進口智能溫控表（使溫度偏差在1內） ，因此保證了管材的質量。
  3. 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

    風洞試驗參數：噴霧藥液為含1 bsf的水溶液，風速1 . 4m s ，風向垂直於噴霧扇面，溫度281k 288k ，相對濕度rh9 20 ；室內試驗參數：噴霧藥液為含2 bsf的水溶液，噴頭處風速為3 . 2m s ，風向平行於噴霧扇面，溫度291k 301k ，相對濕度rh15 21 . 2 ；分別在噴頭下風向噴幅外的空中和地面布點收集飄失和飄移沉積的霧滴量，作為評價減少霧滴飄失效果的指標：試驗結果表明：改進后的罩蓋噴霧減少霧滴飄失的效果好於雙圓弧未開口罩蓋噴霧，常規無罩蓋噴霧的霧滴飄失量大於開口罩蓋噴霧。
