Burnett法P─V─T测定装置

The P─V─T measuring device by Burnett method

根据Ｂｕｒｎｅｔｔ［１］所提出的多次膨胀法原理设计了气体和气体混合物的Ｐ─Ｖ─Ｔ测定装置。该装置结构简单，操作方便，测量精度高。用Ｈｅ和Ｎｚ对该装置进行了校核，二种气体压缩因子的测试结果与文献值［２］［３］符合一致。

The P-V-T measuring device for gas and gas mixtures was designed according to the principle of multiple expansion advanced by Burnett. The features of this device are: simple construction, easy opearation and high measuring accuracy. The device has been checked with He and N2. The test results for the compressibility factor of these two gases are in accordance with the values stated in the literature.
