有一种富有逻辑的话表达：热致荧光变色粉末的制备 此处的热致荧光变色粉末的制备以尼罗红为例先称量 10 g 的软脂酸颗粒于试剂瓶内再称量159 mg 的尼罗红粉与软脂酸混合配置浓度为 00005 mmolg的红色热致荧光变色材料加入转子将试剂瓶盖紧后放入恒温加热磁力搅拌器中水浴 75°C恒温加热待软脂酸部分熔融出现透明液体时打开磁力搅拌开关匀速搅拌至试剂瓶中块状物消失等尼罗红充分溶解呈红色澄清溶液后

This is a logical expression describing the preparation of thermochromic fluorescent powders using Nile red as an example. First, 10 g of stearic acid particles are weighed into a reagent bottle, and then 1.59 mg of Nile red powder is mixed with stearic acid to prepare a red thermochromic fluorescent material with a concentration of 0.0005 mmol/g. The mixture is then placed in a constant temperature heating magnetic stirrer and heated in a 75°C water bath until the stearic acid melts and appears as a transparent liquid. The magnetic stirrer is then turned on, and the mixture is stirred until the solid block in the reagent bottle disappears and Nile red is fully dissolved, forming a red clear solution. The reagent bottle is then removed from the water bath and allowed to cool to a completely crystallized state at room temperature. The crystallized Nile red/stearic acid mixture is then ground into a fine powder using a ceramic mortar until there are no visible large particles and the overall texture is a fine powder
