Breakfast time for most people. Time for a nightcap for us!

那是大多数人的早饭时间，但却是我们临睡前的喝酒时间！

The silver accessories nigrescence changes yellow is the normal natural phenomenon, because in the air and other natural medium's sulfur and the oxide compound and so on have certain corrosive action to the silver, after wearing period of time, will present some small spots, the long time will proliferate Large expanse, will turn the black.

银饰品变黑变黄是正常的自然现象，因空气和其它自然介质中的硫和氧化物等对银都有一定的腐蚀作用，在佩戴一段时间后，就会出现一些微小的斑点，久之会扩散成片，甚至变成黑色。

Finally, the grafting polymerization of textile materials initiated by microwave low temperature plasma was conducted. Knitted cotton fabric was grafted by AMPS first, then knitted cotton and terylene/cotton fabrics were grafted with AMPS/NIPA dualistic monomers respectively. By means of grafting polymerization, the P dualisticintelligent hydrogel was added to textile.The influences of the factors on add-on, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature and time etc, was studied fully. The optimal conditions of grafting polymerization initiated by microwave low temperature plasma were determined by orthogonal design, variance analysis and mathematical statistics method so as to analyze the main influencing factors. Then swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of grafted textile were studied. The performance indexes of hydrostatic pressure, moisture permeability and bursting strength of the knitted cotton and terylene/cotton fabrics before and after grafting were compared and evaluated synthetically.

此后用微波低温等离子体引发纺织材料的接枝聚合反应，分别研究了棉针织物接枝AMPS和棉、涤棉混纺针织物接枝AMPS/NIPA二元单体，使智能凝胶以接枝的方式添加到纺织材料上；详细探讨了微波低温等离子体处理功率和时间、总单体浓度、AMPS单体浓度、交联剂浓度及聚合反应温度和时间等因素对增重率的影响，通过正交设计、方差分析及数理统计对各影响因子进行分析，确定了微波低温等离子体引发接枝聚合的最佳工艺条件；对接枝纺织材料的失水-吸水动力学、温度敏感性、pH敏感性等进行了研究；对接枝前后棉、涤棉混纺针织物的静水压、透湿性和顶破强力等服用性能指标进行了对比和综合评价。
