解(jie)決(jue)問(wen)題(ti)的(de)辦(ban)法(fa)是(shi)改(gai)變(bian)通(tong)風(feng)方(fang)式(shi)，通(tong)過(guo)安(an)裝(zhuang)在(zai)雞(ji)舍(she)末(mo)端(duan)的(de)排(pai)風(feng)扇(shan)進(jin)行(xing)排(pai)風(feng)，關(guan)閉(bi)雞(ji)舍(she)前(qian)端(duan)為(wei)縱(zong)向(xiang)通(tong)風(feng)而(er)設(she)計(ji)的(de)進(jin)風(feng)口(kou)，並(bing)使(shi)空(kong)氣(qi)從(cong)雞(ji)舍(she)側(ce)牆(qiang)上(shang)方(fang)的(de)進(jin)風(feng)口(kou)進(jin)入(ru)雞(ji)舍(she)

這種相對較新的通風方法就是所謂的“過渡期通風”，其qi優you點dian是shi能neng在zai溫wen度du上shang下xia波bo動dong比bi較jiao大da或huo內nei部bu環huan境jing變bian化hua較jiao大da的de情qing況kuang下xia進jin行xing良liang好hao的de通tong風feng。進jin行xing這zhe樣yang的de通tong風feng時shi，我wo們men可ke以yi關guan閉bi雞ji舍she前qian端duan為wei縱zong向xiang通tong風feng而er設she計ji的de進jin風feng口kou，開kai啟qi一yi半ban或huo較jiao少shao的de風feng機ji讓rang新xin鮮xian空kong氣qi從cong雞ji舍she側ce牆qiang上shang方fang的de進jin風feng口kou進jin入ru。這zhe樣yang做zuo的de好hao處chu是shi既ji能neng進jin行xing有you效xiao的de通tong風feng又you能neng改gai善shan雞ji舍she內nei空kong氣qi均jun勻yun混hun合he
