Containing potassium hydrogen isotope tritium measurement of the pressure

The case with tritium were measured during storage containing tritium at a time,[link widoczny dla zalogowanych], this method requires the measurement: (1) measurement (actually recorded) the content of lithium hydride storage device when the initial pressure Pl and the final pressure P2, the the temperature of the container to the same; (2) gas to produce lithium hydride can all be sealed in containers, if the event of a device to vent trickle content, content must be open outside the re-adjustment device, to be adjusted and filled with pure argon gas, re-calculate the start time of storage tI. According to a particular measurement of the amount of heat when the air pressure household records, temperature T and time t and other parameters, we use the \d The relative error of measurement to measure their strengths and weaknesses' d: __ × 100% (17) port where: q is the pressure measurement values, q values for the calorimetry measurements. The results in Table l. Table l back out of storage and measuring about 20 No. 1 Xionghai Lin et al: Lithium hydride containing tritium isotope content of 77 the amount of pressure measurement specific parameters and the results of the calorimetric measurement. from the table 4 the measurement results of lithium hydride can be seen that the results of two methods to measure the relative error of less than 1%,[link widoczny dla zalogowanych], consistent measurement results. pressure method depends on the contents of the error of the sealing device, sealing the case in the present, the total error of up to 196 below,[link widoczny dla zalogowanych], meet actual needs. bad one measurement data and results of two methods Note: Table population is \The pressure difference between the amount of tritium method of deep connection, and the results of this method were compared calorimetry. Comparison of the results can be seen from the air pressure method and calorimetry at the same level of error, while the pressure method has faster to save human and material resources and the advantages of easy operation. So, you can use air pressure instead of calorimetry method to measure. Reference 1 Noel GF. shabu probe and measurement of radiation.
