我想知道下列意思誰能幫幫我翻譯中文給我啊

2.3. Lycopene estimationThe standard method of estimation of lycopene is spectrophotometric(Davis

1949). The absorbance of lycopeneextracted in petroleum ether (40 ml) was noted at three differentwavelengths

viz. 445

472

502. The absorbance atmaximum wavelength (k max) of 472 nm for lycopene inpetroleum ether was considered. The amount of lycopene(mg) was calculated by a specific extinction coefficient(E1%1 cm
