《煤矿安全技术》1985年第二期发表了新疆煤炭科学研究所吕昭双同志所写的“矿井地面塌陷漏风对调风的影响”一文,现就这篇文章中所存在的问题,提出以下几点异议:一、并联网路增阻调风,其中一条支路风量的最大增值究竟是多少吕昭双同志在文章的第二部分并联网路增阻调风中写道:“如图1所示,设并联网路R_1>R_2,其总风阻为R,其风量分别为Q_1、Q_2、Q,设风机的特性曲线为f. “Coal Mine Safety Technology,” 1985, the second issue of Xinjiang Institute of Coal Research Lv Zhao Shuang wrote “Mine Ground Collapse Leakage on the tone of the wind,” the article on the problems are now made the following objections : First, the parallel network increases the resistance of the wind, which one branch of the maximum value of the air volume is how much Lu Zhaozhao double comrades in the second part of the article by the parallel network resistance adjustment tone wrote: "As shown in Figure 1, and The network R_1> R_2, the total air resistance R, the air volume were Q_1, Q_2, Q, set the fan characteristic curve f.
