贵刊90年10期刊登了“关于理想气体排尽液柱的温度问题”一文(下称“关文”)对问题:在长为 L 厘米的玻璃管内有一段长为 h 厘米的水银柱封闭着一段长为a厘米的气柱,如图1-I 所示,玻璃管竖直放置.此时,温度为 T_1,大气压强为 b 厘米汞柱,问:温度至少升到多高,才可使水银柱全部排尽?“关文”得出:理想气体升温膨胀排尽液柱有两种情况:一是气体连续升温,直
In your issue of the 90th issue of your publication, the article “On the temperature of the ideal gas exhausted liquid column” (hereinafter referred to as “Changwen”) is a problem: There is a length of h cm in a glass tube of length L cm. The mercury column encloses a column of air with a length of a cm. As shown in Figure 1-I, the glass tube is placed vertically. At this time, the temperature is T_1 and the atmospheric pressure is bcmHg. Q: The temperature rises at least High, can make all the mercury column drained? “Kuan Wen” is drawn: the ideal gas warming up and expelling the liquid column there are two cases: First, continuous gas temperature, straight
