再用真空光量计定时曝光法成功地分析了HK-40合金，并作出了其工作曲线。
So the vacuum ultraviolet multichannel spectrophotometer is also used to analyse HK-40 alloys by controlled exposure method with the aid of experimentally calibrated curves.
结果表明，电子天平计量法可以将吸管加入溶液体积的计量精度提高2个数量级，从而大大提高了工作曲线的准确性和线性。
It showed that precision of volume was improved hundredfold by electron balance method and thus the accuracy and linearity of the work curve was improved greatly.
