A Gamma curve adjustment method and a Gamma curve adjustment apparatus for a display apparatus. The method includes: obtaining correspondence relationship between current grayscale voltages and first transmittances of the display apparatus, the first transmittances being the transmittances of the display apparatus driving by the current grayscale voltages; determining a target grayscale voltage corresponding to each gray scale based on the correspondence relationship between the current grayscale voltages and the first transmittances and an ideal Gamma curve; generating and outputting the target grayscale voltage corresponding to each gray scale to the display apparatus; and obtaining an actual Gamma curve of the display apparatus driven by the target grayscale voltages as a final Gamma curve. The Gamma curve adjustment method improves the speed and efficiency of adjusting the Gamma curve.

A method for helium mass spectrometric fine-leak test is based on quantitative determination of maximum test-waiting time, which gives a method for quantitative determination of the maximum test-waiting time for fine-leak test during a helium mass spectrometric test process of the sealability, and gives a method for determining the criterion for measured leak rate by taking the minimum helium gas exchange time constant, i.e., a rigour grade &#x3c4;, of an acceptable sealed electronic component as a basic criterion for helium mass spectrometric fine-leak test. Based on the inventive method for quantitative determination of the maximum test-waiting time, for most of the cavity volume ranges, the maximum test-waiting time that is determined accurately may be much longer than 1 hour or 0.5 hour as determined qualitatively by the existing related standards.
