易变色的

Of the ice tea are completely studied based on the analysis of the reasons for the changes in the colour and flavour and the precipitation occurring during the production of the carbonated ice tea from Huaiqing Chrysanthemum flower and Oolong tea,so as to make a clear and refreshing ice tea.

对以怀菊花、乌龙茶为原料制造碳酸型冰茶时，易出现的变色、变味、沉淀等原因进行了分析，并在此基础上，对生产工艺、萃取条件、配方等进行了全面研究，制得清澈透明、清凉芳香的怀菊冰茶。

Our main products are: true, yellow gold glass Mosaic Mosaic （firing on the market at present stickup overcome and the instability of debonded）.

目前公司的主要产品有：烧成真黄白金玻璃马赛克，（烧成马赛克克服了目前市场靠粘贴而成的易脱层变色等不稳定性）。

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。

In this paper,the discolouration and microbes pollution of LAP solution by slow-cooling were indevestigated.
