The invention provides a method for making a printing form having a relief surface on a floor from a photosensitive element. The method involves generating a polymerization rate curve for the photosensitive element from a step exposure test by measuring a cure response, such as floor thickness or one or more relief image characteristic / s, of the element relative to an energy density of a source of actinic radiation. The method exposes a photosensitive element to the source of actinic radiation based on energy density that accounts for changes in intensity of lamps used for the source of actinic radiation.

The invention belongs to the field of environmental protection, and particularly relates to a method for determination of the ecotoxicity of soil contaminated by residues of organophosphorus and pyrethroid insecticides. The method is characterized in that eisenia foetida is selected, and after being domesticated, the eisenia foetida is subjected to an exposure test in the soil to be tested; through the steps of protein extraction, SDS-PAGE protein isolation and Western Blotting detection purity analysis, if a test group and a control group are significantly different and p is less than 0.05, it is indicated that pesticide residues in the soil to be tested are toxic to soil biological growth; and if no significant difference exists, the soil to be tested is not toxic to growth. The method is suitable for early diagnosis and early warning of contaminated soil, greatly shortens the determination time of ecotoxicity, and effectively improves the diagnostic efficiency of soil ecotoxicity.
