3 terms and definitions

GB/T 13962, GB/T 13966 and GB/T 14666 and the following terms and definitions apply to this document. 3.1 Sample electrode samplecathode In the sample analysis, the analyzed sample is used as a cathode for the discharge pair, called the sample electrode. 3.2 On the electrode counterelectrode In the discharge process, with the sample electrode is opposed to the high pressure of the anode part. 3.3 Spark discharge sparkdischarge And a discontinuous discharge generated in the analysis gap formed between the sample electrode and the counter electrode. The discharge current is raised by the periodic charging capacitor for. After the spark is ignited, the discharge is formed, and the voltage between the gaps is calculated from the starting capacitance in a shorter time than the spark duration Pressure to low combustion voltage. Thus, compared to an arc, the spark can be considered essentially an intermittent arc with a high starting current (or peak Current) and short duty cycle (burning time versus non-burning time ratio). 3.4 Pole gauge gauge A gage for determining the distance between the electrode and the sample electrode. 3.5 Tracing profile By adjusting the position of any optical component such as a collimator, an entrance slit, a grating, etc. in the optical system to obtain the optimum luminous intensity. ......
