The calibration method using a high-power halogen tungsten lamp as a calibration source has many advantages such as strong equivalence and high power, so it is very fit for the calibration of high-energy laser energy meters. However, high-power halogen tungsten lamps after power-off still reserve much residual energy and continually radiate energy, which is(More)
Electro-optical equivalent calibration with high calibration power and high equivalence is particularly well-suited to the calibration of high-energy laser energy meters. A large amount of energy is reserved during this process, however, which continues to radiate after power-off. This study measured the radiation efficiency of a halogen tungsten lamp(More)
The pearl oyster Pinctada fucata is an important commercial marine shellfish that is cultured for producing saltwater pearls. In this study, 468 single nucleotide polymorphisms (SNPs) were screened from P. fucata transcriptome data, and 119 polymorphic SNPs were successfully isolated by a two-step small-amplicon high-resolution melting assay. Of these, 88(More)
The nonlinear effect of materials and sensors in high-energy laser calorimeters is especially obvious-due to the steep temperature gradients of their absorbers. Significant measurement errors occur when traditional integral temperature sensors and methods are utilized. In an effort to remedy this, a method is proposed in this paper in which an absorption(More)
