在国家自然科学基金委员会的资助下,我校化学系与科教仪器厂合作,采用频率法原理首次研制成功了WTX—Ⅰ型偶极矩仪。仪器的设计采用集成块电路,以数码管显示,用打印计算器自动打印记录。该仪器测量精度高,它能反映出介电常数小数点后第四位数的变化;稳定性好,恒温下在对溶剂测量时,频率的飘移不超过±2Hz。在对不同类型化合物的测试中均能得到与文献值一致的好结果;整机设计布局合理,小巧实用。目前已由武汉大学科教仪器厂投入小批量生产。
With the support of the National Natural Science Foundation of China, the chemistry department of our university cooperated with science and education instrument factory to develop the WTX-Ⅰ type dipole moment meter for the first time using the frequency method principle. Instrument design using integrated circuit block to digital display, with a print calculator automatically print records. The instrument has high measurement accuracy, which can reflect the fourth digit change after the decimal point of the dielectric constant. The stability is good. When the solvent is measured at a constant temperature, the frequency does not drift more than ± 2 Hz. In the test of different types of compounds can get good results consistent with the literature value; machine design and layout reasonable, compact and practical. Has been invested by Wuhan University Science Instrument Factory in small batch production.
