This project studies, use PH indicator (bromic phenol orchid with bromic cresol green), to different object face (be like plastic board, ceramic tile of Brown paper, thick hard paper, thick chipboard, china, bathroom and cotton cloth) planar dirt shoe imprints had a test, made with reagent of salt of sulfur cyanic acid quite, discover PH indicator is more effective.
本项目研究，使用PH指示剂，对不同的客体表面（如塑料板、褐色纸张、厚硬纸张、厚硬纸板、瓷器、浴室瓷砖和棉布等）的平面灰尘鞋印进行了试验，并与硫氰酸盐试剂作了比较，发现PH指示剂更为有效。

In this study, we developed the ammonia sensing material by using MCM-41 impregnated with bromocresol green. MCM-41 is one kind of mesoporous molecular sieves. It can be applied to many fields due to well-defined pore shapes, narrow distribution of pore sizes, large pore volumes, high surface area, excellent thermal, hydrothermal, chemical and mechanical stability. And the bromocresol green dye is commonly used as a pH indicator with colorimetric from pH 3.8 to pH 5.4.
本研究之目的是结合变色染剂及中孔洞分子筛MCM-41进行氨气吸附，研究中所选择之变色染剂溴甲酚绿是一种偏酸性之大分子有机染剂，其变色范围在pH 3.8到pH 5.4；而MCM-41由於其孔洞大小分布范围狭窄、孔洞体积大、高比表面积、具有良好的吸附容积、表面反应性强及易於改质等优点，故期望利用此复合材料，经气体吸附达到氨的移除并同时在吸附饱和前能产生显色效果。

With sodium succinate as carbon source and bromothymol blue as pH indicator,20 BTB agar plate positive strains were isolated,from which four of them were identified as aerobic denitrifiers.
利用琥珀酸钠作为碳源，溴百里酚蓝作为pH指示剂，共筛选得到20株BTB琼脂平板阳性菌。通过反硝化性能测定，复筛得到4株好氧反硝化细菌。
