style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">所謂通風系統聯網，是指不考慮巷道的實際位置、長度、斷面大小等實際幾何特征，將通風系統圖抽象為點線集成的網絡線路圖，用來表示通風動力、各路線的連接關系以及系統內的氣流分布，即礦井通風系統網絡圖。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei";

14px;">(2)節點：分支的交集稱為節點；通常，風路與大氣相交的點也被設置為節點。對于每個分支，它與兩個節點相連，其中風流入分支的節點稱為分支的開始節點，風流出分支的節點稱為分支的結束(結束)節點。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 14px;">(3)環：由兩個以上的分支(分支不重疊，只有一個節點重疊)組成的封閉風路徑稱為環或網格。</span></p><p style="text-indent: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size:
