本文介绍的卡计是在Findlay等设计的卡计的基础上经改进而成。与原卡计相比,我们制造的卡计具有结构简单、制造成本低等主要特点。原卡计需用8个大小不同的B室来调节混合摩尔比。我们改进后的卡计只需用三个大小不同的B室和两个容易加工的搅拌器便能获得十二种不同的混合摩尔比。此外,我们还进行了电路分析,从理论上证明了用多个相同的热敏电阻并联使用。可获得更高的灵敏度。我们用这个卡计测量了苯——环已烷系统在25℃时的混合热。测量结果与从文献上获得的数据比较,误差在1%以内。
This article describes the design of the card is based on the design of the Findlay cards based on improved from. Compared with the original card, we manufacture the card meter has the advantages of simple structure, low manufacturing cost and other main features. The original card is required to use eight different sizes of B room to adjust the mixing ratio. Our improved card counts up to twelve different mixing ratios with just three different size B cells and two easy-to-handle mixers. In addition, we also conducted a circuit analysis, in theory, proved that the same number of thermistors used in parallel. Get a higher sensitivity. We used this card meter to measure the heat of mixing of the benzene-cyclohexane system at 25 ° C. The measured results are compared to the data obtained from the literature with an error of less than 1%.
