1) the gas ionization bringing device (2) is placed on to the outer glass tube (7) of groove type solar thermal-collecting tube (6) to be measured
On；
2) power is applied to copper plate electrode (5) by high frequency electric source (1), it is empty in the annular of groove type solar thermal-collecting tube (6) to be measured
Between high-frequency electric field is formed in (14)；
3) high frequency electric source (1) power is adjusted, when electricity occurs for the interior gas of the annular space (14) of groove type solar thermal-collecting tube (6) to be measured
From when, record the output voltage and current values of high frequency electric source (1), and by spectral detection system (3) spectra re-recorded data, point
It analyses spectral signature wavelength and spectral light shines strength values, for identifying the gas componant and pressure in annular space；
4) when annular space (14) gas of groove type solar thermal-collecting tube (6) to be measured, which fails electric discharge, generates light-emitting plasma,
The electric current of high frequency electric source (1) is then adjusted to a certain fixed value, the output voltage numerical value of high frequency electric source (1) is recorded, it is empty to analyze annular
Between gas pressure intensity in (14).
