求翻译：实验结果表明：通过甲苯-2，4-二异氰酸酯（TDI）和环氧丙醇的反应制备双羟基环氧化合物，反应过程采用二正丁胺滴定法测定异氰酸酯基团的含量减少为空白实验值的56%-68%，反应过程中环氧值不变以及滴加二乙醇胺二步反应过程中测定剩余NCO含量减少到空白实验值的23%-33%，且反应产物环氧值与反应前相比较没有变化。是什么意思？

The experimental results show that: toluene 2,4 - diisocyanate ester (Tdi) and the reaction of glycidol preparation dihydroxy epoxy compounds, reaction with dibutylamine titration method for the determination of isocyanate ester group content was reduced to blank experiment value 56% -68% of the epo
