原理及仪器近几年来有很多的实验性的和综述性的论文发表,叙述关于无线电频率范围(几十仟周至几百兆周)的高频电流在容量分析和物理化学的研究中的应用。被分析的溶液是放在薄玻璃池(小玻杯、试管、玻管)里,池的外壁,装有两块相互绝缘的金属片,或是一个线圈(图1)。前者构成一个电容器,后者是一个电感,联接在高频振荡管的栅极
PRINCIPLES AND INSTRUMENTS In recent years there have been many experimental and reviewable papers published that describe the application of high frequency current in the radio frequency range (tens to thousands of megabytes) in capacity analysis and physico-chemical research. The solution to be analyzed is placed in a thin glass cell (small glass cup, test tube, glass tube) on the outer wall of the cell with two mutually insulated sheets of metal or a coil (Figure 1). The former constitutes a capacitor, the latter is an inductor, coupled to the high frequency oscillation tube gate
