Abstract

Having filled a fresh, tube w ith fresh spun glass, I carefully exhausted w ith th e Sprengel pum p on January 24th, and the exhaustion was kep t up till February 5th, th a t is, fo r twelve days. During th is tim e I frequently tested w ith th e McLeod gauge. A very i slight increase of pressure was found during th a t in te rv a l; bu t it was iso slight th a t I am not able to say th a t i t was g reater th an th a t
2对地下温度,对岩石的导电性,对饱和和渗吸的热效应,以及对山脉中特殊热源的观察
1月24日,我用崭新的纺纱玻璃填充了一个新管子,然后小心翼翼地用斯普伦格尔泵把它抽干,一直抽到2月5日,也就是最后一天,抽了12天。在这段时间里,我经常用麦克劳德量表进行测试。在这段时间内,压力有非常轻微的增加;但它非常小,以至于我不能说它比我们一直观察到的,甚至在斯普伦格尔泵井然有序的情况下,在真空中保持几天的情况下,它都要大。2月5日,我将三、四瓶汞通过泵浦,从麦克劳德表可以看出,真空度约为0*5 m。然后我加热,从纺丝的玻璃中冒出了大量的气体。像以前一样收集并分析了这些数据。玻璃纤维的数量为15,500,估计表面积为3527平方米。释出的气体总量为0.41℃;在我的第一个实验中,这个比例要小得多。在这些气体中,发现有78.6%是碳酸气体(可被苛性钾吸收)。低于10.5%的是氧气(被焦性没食子酸和钾肥吸收);而89.5 %的人则没有得到任何回报。m可能主要是氮。很大比例的碳酸气体rem arkable,我很难解释,除非我们m ay假设th t在大型全被玻璃tity d u rin g操作画出玻璃纤维,并附上我在th e t包含ing tube-operations期间,在这些预备考试inary试验的力量,充足的供应从吹管火焰。1885.[英语单词地下名词
